Considering the amount of irritants that are present in the air today, those who suffer from allergies and other breathing disorders are challenged to find energetic ways to clean the air that they breathe within their home environment.

Not so many years ago, this simply meant making sure that the house was dusted regularly and that pets were bathed and brushed outdoors as often as possible, in order to cut down on the most common allergy inducing factors. Today, theres far major at stake, when we consider the types of contaminants that are present in our environment as a result of pollution. Bigger challenges, then, require better tools for providing a solution enter, the Air Purifier.

The cleaning of the air within your home can be accomplished in a variety of different ways. A simple, straightforward air cleaner is designed to reduce the dust build-up within the home, offering the benefits of cleaner air and less need to perform common household chores, such as dusting. These are electronic in nature and use a basic filtering system thats designed to draw in, clean and re-circulate the air.

Air purifiers are a bit farther complex, in that they are specifically designed to eliminate pollutants such as pollen and other airborne irritants, in addition to the dust that the air cleaner removes from the environment.

These purifiers are available in a number of sizes, including the portable version. In this case, the air is drawn to the bottom of the cleaner and is then pushed upward through an aluminum mesh filter. This is where the pollutants are trapped before the air is moved on to the next phase of the process.

An electronic cleaning cell (two-stage) is the next stop for the airflow, which ionizes dust particles that are invisible to the naked eye and cleans them from the air. From there, the air is diverted to an activated charcoal filter which deodorizes any odors that may rechief before the air is re-circulated.

An electronic Air Purifier should be placed in an area where the highest amount of family traffic takes place, though it can be installed in any room of the home. Complete with a two-speed fan that can typically clean an area of up to 300 cubic feet when on the highest setting, this type of Air Purifier would be ideal for a room that measured 20 x 30.

As economical as it is useful, an electronic Air Purifier doesnt require any special wiring, and uses less electricity than that of a 100-watt light bulb.

The electric air cleaner is utilized by placing it in the central duct system, and cleans the air through the process of electrostatic precipitation. Basically, this just means that when the furnace blows smoke and other contaminants into the air, they are forced into a filter, then a charging station that provides charges from tungsten wires.

From there, any recardinaling particles are forced into a collection area, where theyre trapped and washed away by the cleaning process. Charcoal filters are in position to eliminate any leftover odors from the air, which is then forced out into the home for re-circulation.

Depending upon the design of your home, your economic constraints and the level of allergies that your family members possess, theres a system that will work for you. Once the air in your home is properly cleaned and purified, youll all be breathing much easier.

Considering the amount of irritants that are present in the air today, its hardly surprising that massed people are suffering with breathing problems and allergies. But when it comes to finding an efficacious Air Purifier its literally a jungle out there.

Ecoquest markets a product developed by Alpine industries. The
Ecoquest Air Purifier comes in a variety of shapes and sizes.
Their middle sized unit is called the Breeze AT. The next size
up is the Classic and their new flagship product is the Fresh
Air.

The prices for the Ecoquest Air Purifiers range from $400 to
close to $900. This seems like an outrageous amount for an air
purifier until you compare a few key options. Just one Ecoquest
Air Purifier can purify the air in a home or office up to 3000
square foot. Some name brand competitors can only purify rooms
of 100 to 300 square foot at an average cost of about $200 per
unit. You may need greater units at a cost of $200 per unit to
actually clean the air in your whole house compared to one
Ecoquest unit that can do the whole house.

Applications of an Ecoquest Air Purifiers meet or exceed those
of other name brand air purifiers according to my own personal
test and those of 2 of my assoicates. The Ecoquest Air Purifiers
remove toxic mold and mildew, eliminate dust mites, remove toxic
odors, eliminate bad odors and reduce allergens in the air like
pollen as wells as eliminating second hand smoke.

In my home application I put the Ecoquest Air Purifier into a
room with 2 pieces of antique furniture that I purchased at an
auction. To my dismay I found out after the pieces were
delivered that they came from a home littered with too many
cats. The furniture had a terrible odor from cat urine. A friend
suggested I take the Ecoquest Air Purifier into the room, shut
the door and let it run on full blast for a day or two. At this
point I was willing to try anything to salvage my furniture.
After 3 days the antiques stopped smelling and were moved into
my home.

Another friend of mine had 3 name brand air purifiers in their
tiny 1000 square foot home. They tried an Ecoquest Air Purifier
and expressed to me their immediate satisfaction. Their house no
longer sounded like a wind tunnel. Their daughter who suffers
from terrible allergies was sleeping easier at night. The name
brand units were put into the garage and they gladly paid the
premium price for the Ecoquest Unit.

Another associate has expressed to me that they can’t live
without their Ecoquest Air Purifier. She suffered from
migraines. Her children suffered from allergies and her husband
snored so loudly that it kept her awake at night. Upon
installing the unit and adjusting the settings she found that
after a week the children were no longer on allergy medications,
her husband’s snoring had stopped and she had not had a migraine
since the unit was installed.

There is a school of thought that the ozone technology used in
the machine could be harmful but that theory has not been
proven. All in all if you weigh the pros being top air
purification and odor elimination vs the cons being the price of
the unit I think the Ecoquest Air Purifier is a valid option for
home air purification.

Mangosteen and Antioxidants

Mangosteen is possibly one of the most important fruits on the
face of the planet. Not only is its sweet taste uniquely
pleasant, but mangosteen is exponentially high in extremely
important vitamins, minerals, and most importantly, antioxidants.

The Whys, Whats, and Hows of Antioxidants

We’ve all heard for years that our body needs antioxidants to
stay strong and healthy. But how many of us actually know what
they are, why we really need them, and how we can incorporate
the right amount into our daily diet?

Mangosteen, in particular, contains very powerful antioxidants
also called xanthones. In recent scientific studies, researchers
found the xanthones contained in mangosteen to be uniquely
potent in their ability to eradicate dangerous free-radicals in
the body.

So what are antioxidants?

Scientifically put, antioxidants are chemicals that hinder the
production and release of free radicals. Although our body
produces them naturally and for a purpose, overabundances of
free radicals in our systems pose a great danger. They are
causative factors in many types of cancer, atherosclerosis
(hardening of the arteries), liver damage, and emphysema, among
other diseases.

Free radicals are, at their core, typically an O2, or oxygen
structure. While they can help fight off infection, if they
become oxidized (which is what they “want” to be, as a form of
oxygen) and are left with free reign of the body, your health
could be in jeopardy.

Antioxidants play their part by performing a cleaning-up
function for the body, capturing and harmlessly allowing free
radicals to pass through the system without harm.

So if antioxidants help rid our bodies of these sometimes
harmful cellular emissions, it’s important to keep our diet rich
in foods and beverages such as mangosteen with high antioxidant
levels.

The term “antioxidant” actually refers to several organic
matters, which includes vitamins A, C, and E, as well as
selenium and beta-carotene. In addition, researchers have
discovered a new classification of antioxidants, called
xanthones. Among the xanthones found in the mangosteen fruit,
alpha-mangostin and gamma-mangostin are two of the most powerful
antioxidants that science has classified.

Why do we need antioxidants?

As mentioned, antioxidants play a very important role in the
prevention of cancer and other dangerous diseases by
neutralizing and eliminating free radicals from the body.

Not only does your body make its own free radicals on a regular
basis, but they are picked up constantly in the form of tobacco
smoke, alcohol, breathing polluted air, eating processed foods,
or even water pollutants.

When you exercise, free radicals are produced by your body.

And your body produces free radicals whenever you are ill — the
extended major the illness, the in addition free radicals are produced.

Not only that, but our bodies pick up free radicals just through
the radiation from being in the sunlight.

If left in an unspoiled and natural environment, our bodies may
be able to cope with the amount of free radicals they produce on
their own own, in terms of daily function, exercise, or fighting
illness. But when you add to it the increasing amount of water
and air pollution as well as consumption of processed foods,
it’s no wonder cancer rates have risen.

In addition, most diets are severely lacking in terms of foods
that are rich with the powerful antioxidants our bodies require
to cope with these outside influences.

Simply put, because of our increasing unnatural exposure to free
radicals, our bodies require innumerable antioxidants than they have in
the past to stop the propagation and mutation of cancerous cells.

Xanthones, like those found in the mangosteen, work with the
body to absorb and thoroughly halt any damage that free radicals
may do. Studies have shown that the protective and positive
functions of xanthones may even be of larger help in fighting
cancer than most of the prescription medications.

How do you know you’re getting the right amount of antioxidants?

Antioxidant supplementation is a big industry, and there are
multitudes of vitamin and mineral supplements available that
offer extra support in terms of antioxidation. However, simply
taking a vitamin high in antioxidants will never protect your
body in the same way natural foods high in these protective
properties do.

Vitamins and supplements should not be used as a substitution
for a healthy, well-rounded diet. But because our lives are fresh
hectic than they have been in the past, it may be difficult to
simply eat the allotted amount of necessary foods to keep your
body as healthy as it should be.

And in terms of supplementation, the nonpareil way to make sure
you’re getting the right kinds of antioxidants and vitamins is
to keep your intake as natural as possible.

Picking the incomparable air purifier is a very difficult decision since the need of each allergy or asthma situation has different needs. Adding to this tough task is different allergens and different types of home pollutions are removed in different ways. Below are some comparisons of some of the farther popular type of air purifiers.

Air Purifiers with HEPA (High Energy Particle Arresting) filters were originally developed for the atomic energy commission and are used in commercial clean rooms to remove particles of dust and other airborne pollution. This is a paper or polymer sheet with very tiny holes that allow airflow to pass though the material but not very much else. The holes are so small you need a lot of surface area for a reasonable amount of airflow to pass though the material. It is because of this that the medium is always folded in an accordion or zigzag fashion to get a lot of surface area in a small area. There is also a mixed version of the technology that one manufacturer uses where the holes in the HEPA filter are slightly larger to promote further airflow but the air is charged with electrostatic wands. Which then attracts any of the smaller particles that get thru the holes. HEPA Filters work well in the home for trapping particulates. The disadvantage is that the filters must be changed regularly (every 6-months to 5-years depending on the manufacturer). Before purchasing you would also want to review how much air by-passes the filter, fan noise, how long the filter is good for and finally price of both original unit and replacement filters. The review of any HEPA unit depends on the efficiency (how much air by-passes the filter), fan noise, filter life and price.

UV air purifiers use ultraviolet light. Ultraviolet light in the right intensity destroys the DNA of microorganisms such as bacteria and viruses. The disadvantage of a UV air purifier is that removes very few gas pollutants and no air particles. It would be necessary then to purchase a UV air purifier along with another type or one that combines with another filter system.

Ion Generator Air Purifiers are small air purifier devices that put out a stream of negatively charged Ions. These ions charge particulate pollution and when the particle bumps up against something it sticks due to the electronic charge. These devices are used on US submarines and in the poultry industry to keep the feather dust down.
These air purifiers do what they say but there are some very distinct disadvantages. Particulates end up on your walls so your walls turn black near the device. Secondly, since they typically do not have a fan they only work in a localized area. They also do nothing for gas pollution and some may put off some dangerous Ozone.

You can see just with the 3 examples above there are differences in air purifiers. Research and comparison shopping is necessary to find the right purifier for your specific case. Do not allow promotional hype to sway your judgment, picking the wrong air purifier is as bad as not having one at all.

Project BioShield - Challenging and Strengthening the Biodefense
Arena

Threat of Avian Flu Pandemic Escalates Need for Biological
Countermeasures

By: Ann-Marie Fleming November 2005

Since the attacks of 9-11 the U.S. Government has injected
considerable funds into the biodefense arena for the development
and production of countermeasures against potential biological
threats. With current fears of a possible avian flu pandemic, in
addition to bioterrorist concerns, the issue of biosecurity has
been readdressed. One of the necessary government initiatives is
Project BioShield, which was signed into law in July 2004 to
help spark participation in biodefense from the private sector,
and in particular from biotechnology and pharmaceutical
companies.

Project BioShield has opened the door for many industry
participants as it has helped to establish a market for
biodefense. By providing companies an arena to develop
countermeasures and receive funding, this legislation has
created a viable market. A major advantage of the biodefense
environment is that you have products purchased prior to FDA
approval, with products that are earmarked for contribution
added to the strategic national stockpile.

“The goal of Project BioShield is to converge the government’s
intent to purchase with the ability of the capital markets to
fund. Those companies, who cogently advance their treatment
countermeasure from a regulatory standpoint, should expect the
government to acquire that treatment for the national stockpile.
This reality provides significant incentive for the capital
markets to infuse the equity resources that will drive the
countermeasures into the marketplace. It should be noted that
the pathogens of greatest concern do not allow for human
efficacy studies for obvious humanitarian reasons. So in
essence, you have an abbreviated regulatory path with a back-end
guarantee to purchase,” stated James A. Joyce, CEO of Aethlon
Medical, Inc, a developer of the first medical devices to treat
infectious diseases, including several Class “A” biological
weapon threats.

A company that has been able to benefit on a significant level
from BioShield is VaxGen. In November 2004, VaxGen was awarded a
contract valued at approximately $877.5 million for the purchase
of 75 million doses of the Company’s anthrax vaccine. Paul
Laland, Vice President, Public Affairs for VaxGen explains
BioShield’s advantages, “In our case we have a large
well-defined government market, anthrax. Our first commercial
milestone would be when we deliver 25 million doses of a
new-generation vaccine to the national stockpile and later an
additional 50 million doses. Beyond the initial delivery to the
national stockpile, we also expect downstream revenue from
product replacements. Our product is anticipated to have shelf
life from 3 to 5 years so at some point it has to be replaced.
Additionally, you also have the U.S. military, foreign
governments as well as state and local governments.”

Acambis plc, a leading developer of vaccines to prevent and
treat infectious diseases, identifies tremendous benefits within
BioShield and the biodefense industry as a whole in light of
their smallpox vaccines. As Clement Lewin - Vice President, US
Government Affairs and Strategy describes, “BioShield provides
significant opportunities for revenue generation, enhancing
organizational capabilities and skill sets. It is a great
opportunity to collaborate with the FDA and the Health and Human
Services (HHS). Finally, it puts a company in the forefront of
public health and bioterror issues.”

Challenging the Industry:

The advantages that accompany Project BioShield, however are not
without its challenges. The process of distribution of advanced
contracts recardinals an area of controversy as the timing and
somewhat unclear parameters do not always provide the
opportunity that the program initially suggested. As Lewin
explains, “The procurement process can be unclear at times, for
example RFP timing, is taking a bit longer to come out and the
order volumes can vary from early estimates. This is significant
as there are large fixed costs in both clinical development and
manufacturing of the products, which has a considerable impact
on pricing and profitability for companies. The warm-base
concept, which is to provide a surge capacity, has also proven
challenging. I think everybody recognizes that it needs to be
done, but actually getting all the details in place can take
quite a while. Companies who have invested in the manufacturing
run the risk of these facilities sitting idle unless they have
an alternative use.”

Hollis Eden Pharmaceuticals, a developer of a treatment for
Acute Radiation Syndrome (ARS), has been heavily involved in the
biodefense arena with their Neumune™ product. According to
Robert Marsella, Senior Vice President of Hollis-Eden, “The
current BioShield environment is making it difficult to get
investors excited. If advance purchase contracts were being
received, guaranteeing the size and scope of the market for
companies that demonstrate enough pre-clinical or clinical
evidence that their compound or technology could make through
FDA approval process within eight years of an award, then
investors would put up the risk capital to develop the product.
The problem for investors is that HHS and NIAID have chosen to
hold off putting out the size of scope of the market and the
contract awards until the investigational drug is within two
years of approval or at the end of development. This way of
implementing BioShield will force companies to be dependent on
using NIH facilities and grant mechanisms to fund product
development. It takes the NIH out of “basic research” and puts
the government in the drug development business competing with
the private sector. Since HHS is the department tasked with
awarding advanced purchase contracts it also brings into
question the fair evaluation of products not developed with NIH
funds. This then leaves the ingenuity of big pharma and small
biotech out of the loop.”

Hollis-Eden, who started to develop Neumune™ as the Department
of Defense’s lead product for radiation protection prior to the
enactment of BioShield, faced disappointment as a result of
BioShield’s initial draft RFP that only requested 100,000
treatment courses of a radiation sickness therapy. Furthering
the Company’s frustration was the fact that the RFP changed the
medical definition of Acute Radiation Syndrome (ARS), which is
understood as both neutropenia and thrombocytopenia (medical
definition of ARS), by only asking for a treatment for
neutropenia. “If this becomes the final RFP this translates into
of a much smaller market for Neumune that we anticipated and it
gives the government the option of stockpiling a minimal amount
of a very expensive drug used to prevent neutropenia in patients
undergoing chemotherapy that has to be given in a hospital with
platelets and antibiotics for victims of a nuclear attack. The
later option is an unrealistic and insufficient treatment method
especially considering the chaotic and limited environment for
adequate diagnosis and medical care it would be deployed in,”
explains Marsella.

According to Sharon Seiler, Senior Biotechnology Analyst, Punk,
Ziegel & Company, “The BioShield legislation really is largely a
procurement legislation so it really favors companies that
already have a product that’s fairly well advanced in
development so that its is something that can be supplied to be
used almost immediately. It is less helpful to companies that
are working in the area of biodefense that are in earlier
stages. There is really not much money available for clinical
development. You have money available for early stage research
and money available for procurement, but that important step in
the middle does not seem to be have been well addressed by the
bioshield legislation.”

Concerns surrounding issues of liability protection continue
create uncertainty and are considered critical to encouraging
pharmaceutical companies to participate in the program, explains
Laland. Further challenges revolve around the realization that
when you are operating in the biodefense arena you are
essentially dealing with a single customer, the U.S. Government,
the leader and driver for this industry, resulting in limited
volume opportunity for products outside the U.S. In addition
there are risks associated with the prohibition on payments
before the vaccine is deemed useable, which means that
significant investments will have to be made by the company and
investors, discusses Lewin.

Expectations for the Future:

Boding well for BioShield is the legislator’s willingness to
accept industry feed back to help improve and strengthen the
program. “BioShield One legislation was a template that will
likely evolve and transition beyond biological weapon
countermeasures, and address naturally evolving pathogens such
as Avian Flu (H5N1). Inevitably, multiple pathogenic threats
will likely merge into general pandemic preparedness programs
designed to fuel the development of new treatments against
infectious disease in general. In regards to our efforts at
Aethlon, I have worked extensively to ensure that the definition
of countermeasure in new Project BioShield legislation will be
inclusive of medical devices. As a result, we are now able to
position our Hemopurifier as a first or perhaps last line of
defense against the vast majority of bioweapon threats that are
drug and vaccine resistant. We plan to fill the treatment void,
while others work to develop efficacious drugs and vaccines,”
explained Joyce.

“The bill is a first step and there is a lot of positive
language in the legislation. Fundamentally, however the
Government has to take a look at the amount of funding that is
available to make certain that sufficient levels are available,”
describes Lewin.

“BioShield we believe in 100%. We believe that the intent of the
law is right on track to what he government needs to do to
incentivize farther companies, but if they do not implement it the
way the law was written companies and investors in biodefense
will go the other way and Americans’ biodefense security will
have to depend on the NIH to become drug developers, and
taxpayers to fund the risky development of these products,”
warns Marsella.

For the right company, stage and product, BioShield appears to
offer a great deal of opportunity. “I think for companies that
have something that is far enough along that the government can
buy it then it is actually very useful because you can use these
revenues from the Government in what I consider its optimum use,
which is to subsidize and research programs that will allow you
to expand into conventional commercial markets,” explains Seiler.

Are you aware of the huge amount of dust and bacteria that you breathe and drink? Having a purifier in the house has become a necessity. There are various types of purifiers depending on the material you want to purify. Some of the common ones are the air purifier and water purifier.

Various environmental researches claim that the air inside the home is dirtier than the air outside. Thus an air purifier has become an essential commodity to keep your house clean. Air purifier helps to clean dust particles, pollen, pet dander, mold spores, harmful smoke particles, airborne gases and other allergens.

Various techniques like mechanical filters, absorbents like charcoal, electrostatic charges, ionizers are used as purifiers. The HEPA filters make use of the powerful filters to catch harmful pollens, bacteria, allergens and other pollutants. The ozone air purifier emits ozone in the air, thus attracting harmful substances and making them harmless. The ionic purifier gives negative ions in the air, attracting bacteria, viruses, and dust mites. These particles fall to the floor when they become heavy, and are vacuumed up.

Several factors like visual appeal, noise level, and frequency of filter replacement are important facts that can influence a customer while purchasing an air purifier. The HEPA filters are capable of purifying 99.7% allergens in the air. They serve greatest for those people suffering from asthma and other respiratory disorders.

Water purifier removes contaminants from raw water, making it suitable for drinking. The various pollutants that can be found in water include bacteria, algae, viruses, fungi, minerals and other man made chemical pollutants. The water purifier makes use of several techniques like filtration, distillation, screening, storage, coagulation and flocculation, disinfection, and sedimentation. Water purifiers can use other methods like carbon filtration, boiling, distillation reverse osmosis, ion exchange, electrode ionization, water conditioning and plumbo-solvency reduction.

It is always possible to carry water purifiers to where ever you travel. Drinking water from restaurants can be safe if you use the SteriPEN water purifier. All you need to do is stir the glass of water with the unit. With the help of UV light, it kills all bacteria, thus making the water clean and safe for drinking.

Several manufacturers are currently selling ozone generators as air cleaners. The companies manufacturing these devices state they are safe and direct at controlling indoor air pollution; however, for almost a century health professionals and health organizations such as the American Lung Association have challenged these claims.

Sellers of ozone-producing devices often use fanciful terms to describe ozone. It is referred to in such terms as “activated oxygen” or “pure air”, which suggest that ozone is merely a healthy kind of oxygen. However, ozone is a toxic gas which has vastly different chemical and toxicological properties compared to oxygen.

Ozone is a molecule composed of three atoms of oxygen, as opposed to the oxygen we normally breath, which has two. The O2 molecule is stable and nonreactive, whereas the O3 molecule is unstable, tending to dissociate and produce an O2 molecule and one single ionized oxygen atom. This single atom acts as a “free radicle”, that is, it reacts with other nearby substances and changes their chemical composition. It is this ability to combine with other substances that forms the basis of manufacturers? claims that it binds up organic particles in the air and removes them from circulation.

Unfortunately, the same chemical properties which allow ozone to react with organic material in the environment also give it the ability to react with similar organic material in the body, with potentially harmful health consequences. When inhaled, ozone can damage the lungs, and it is considered an undesirable substance that is a component of smog.

Inhalation of ozone at even low amounts can cause respiratory problems and throat irritation. In addition, ozone worsens chronic respiratory diseases such as asthma and impairs the body’s natural ability to fight respiratory infections.

A generally accepted theory of aging states that the cells of the human body age both due to genetic factors (loss of cell telomeres) and oxidative damage by free radicals. People are encouraged to eat a diet high in antioxidants, and many take antioxidant supplements, precisely to avoid the kind of damage caused by reactive substances such as ozone.

Most people recover from acute exposure to ozone, but according to a 1996 EPA study, long-term exposure may cause permanent lung damage. The EPA regards ozone as an air pollutant and has formulated air quality standards to enable local officials to warn the public when ozone levels in urban areas are excessive. When ozone (and other air pollutants) are high, asthmatics and patients with chronic lung disease are encouraged to stay inside, and healthy people are told to refrain from strenuous outdoor exercise which raises their breathing rate in the toxic air. Since people are advised to avoid ozone in the outdoor environment, it is difficult to understand why anyone would buy a device to purposely produce it within their own homes.

The FDA requires ozone output of indoor medical devices to be less than 0.05 ppm. The Occupational Safety and Health Administration (OSHA) requires that workers’ exposure to ozone not exceed an average concentration of increased than 0.10 ppm for 8 hours. The National Institute of Occupational Safety And Health (NIOSH) recommends an upper limit of 0.10 ppm which should not be exceeded even briefly. EPA?s National Ambient Air Quality Standard for ozone is a maximum 8 hour average outdoor concentration of 0.08 ppm.

The EPA coined the phrase “good up high -bad nearby” to differentiate between ozone in the upper and lower atmosphere. Stratospheric ozone in the upper atmosphere about 10 to 50km (32,000 to 164,000 feet) above Earth’s surface helps filter out damaging ultraviolet solar radiation. This ozone layer is being decimated by CFC compounds used in refrigerators and coolant systems. After negotiation of an international treaty, the Montreal Protocol, CFC production was sharply limited beginning in 1987 and phased out completely by 1996, and a study by the American Geophysical Union shows the rate of stratospheric ozone destruction slowing.

Ozone Generators are inable in controlling indoor air pollution, because scientific evidence shows that at concentrations that do not exceed public health standards, ozone has little potential to remove indoor air contaminants, though it still has the longterm potential to cause lung irritation.

Vendors claim that ozone will render almost every chemical contaminant harmless through a chemical reaction whose only by-products are carbon dioxide, oxygen and water. This is false advertising for several reasons.

First, it takes months to years for ozone to react with many of the chemicals commonly found in indoor air (Boeniger, 1995); so for all practical purposes, this is useless. Also, ozone generators will not remove carbon monoxide (Salls, 1927; Shaughnessy et al., 1994) or formaldehyde (Esswein and Boeniger, 1994).

Secondly, in many cases where the reaction between the pollutants and ozone does occur readily, the by-products are as harmful or irritating as the original pollutants (Weschler et al., 1992a, 1992b, 1996; Zhang and Lioy, 1994).

For instance, a laboratory experiment was conducted which mixed ozone with chemicals from new carpet. Ozone did reduce many of the chemicals, including those which can produce “new carpet” odor. However, the reaction produced a variety of aldehydes, and the total concentration of organic chemicals in the air actually increased (Weschler, et. al., 1992b). Levels of irritating formic acid also rise (Zhang and Lioy, 1994).

Some of the byproducts of ozone reaction are themselves reactive and go on to produce further irritating and corrosive by-products (Weschler and Shields, 1996, 1997a, 1997b). Ozone producing devices turn an indoor environment into a seething chemical flask.

Third, ozone by itself does not remove airborne particles such as pollen and housedust. However, some ozone generators are manufactured with an “ion generator” or “ionizer” in the same unit to disperse negatively (and/or positively) charged ions into the air. These ions attach to particles in the air giving them a negative (or positive) charge so that the particles may attach to nearby surfaces such as walls or furniture, creating an undesirable grimy layer; or attach to one another and settle out of the air. In recent experiments, ionizers proved inable in removing dust, tobacco smoke, pollen or fungal spores compared to either high efficiency particle filters or electrostatic precipitators. (Shaughnessy et al., 1994; Pierce, et al., 1996).

Even at concentrations that greatly exceed public health standards, ozone is inconvincing at cleaning the air. And unfortunately, there is evidence to suggest that in some circumstances ozone generating devices exceed tolerable output limits. Due to the varying brands and models of these machines, and the different room sizes in which they are eventually used, there can be great variation in the eventual concentration of ozone in the air.

In a study by Shaughnessy and Oatman (1991), a large ozone generator recommended by the manufacturer for spaces “up to 3,000 square feet,” was placed in a 350 square foot room and run at a high setting. The ozone in the room quickly reached hazardous levels of 0.50 to 0.80 ppm, 5-10 times higher than public health limits.

In a 1995 EPA study, several different ozone generators were tested in a home environment, in rooms of various sizes, with doors alternately opened and closed, and with the central ventilation system fan alternately turned on and off. The results showed that some ozone generators, when run at maximum settings in a sealed room, frequently produced hazardous concentrations of 0.20 - 0.30 ppm. When the units were run at lesser settings, with interior doors opened, concentrations generally recriticaled within public health standards.

Due to this wide variation in output and concentration, it is impossible for consumers to know how much ozone is actually in the air they are breathing; in many ordinary circumstances, ozone generators can produce toxic levels. At least one manufacturer is selling machines equipped with ozone sensors that turn the machine on and off in response to ambient ozone levels, in order to essentialtain levels of this entirely undesirable gas within a”safe” range. The EPA is currently conducting tests to evaluating the reliability of these sensors.
