If you watch television late at night, you are probably familiar
with a filterless air purifier called the Ionic Breeze. These
systems have benefits and drawbacks. Lately, there has been some
controversy over their safety. Some consider them to be unsafe,
while others swear by the results. How a Filterless Air
Purifiers Work A filterless purifier works by giving the
incoming air an electrostatic charge. This charge also charges
particles in the air. The air is then moved past an oppositely
charged collection grid. The impurities in the air are attracted
to the grid, like a magnet. The grid must be removed
periodically and cleaned of the impurities. This is easily done
with a damp cloth. Once the grid is completely dry, replace it
and turn the machine back on. These systems can be installed on
a forced air heating system to treat the whole house, or can be
purchased in portable units.
This process creates ozone in the air. If you have been outside
after a thunderstorm, you have smelled natural ozone in the air.
These systems clean the air the way nature cleans the outdoor
air.
However, some feel the ozone that is created can be a health
hazard, particularly if it is highly concentrated. If you are
using a portable air cleaner, be sure it isn’t too big for the
room in which it is being used. The square footage is listed on
the box and in the owner’s manual. Another option is to run it
for a while and then turn it off before using the room. Benefits
of a Filterless Air Purifier There are no filters to change with
this type of purification system. Replacement filters can be
expensive and not having one saves money in the long run.
They use a collection grid to collect impurities, rather than a
filter. The impurities stick to the grid and are wiped off with
a damp cloth. Once the grid is clean and dry, place it back in
the machine and turn it on.
The filtration process leaves a fresh smsell in the air that
many people find vitalizing. You won’t need to use air
fresheners with these systems.
They are nearly silent when running. This is great for night
time use. Some air purification systems can be very noisy and
may need to be turned off at night. Drawbacks of Filterless Air
Purifiers The safety of these filtration systems was called into
question a few years ago when Consumer Reports gave the Ionic
Breeze a bad review and called it hazardous. The reason is the
ozone that is a by product of the purification process. Ozone is
a pollutant and can be irritating to people with asthma or other
respiratory disorders. Sharper Image responded by adding a
component called “Ozone Guard” which is said to convert most of
the ozone into oxygen. On a later review, Consumer Reports still
gave the machine low marks, but said the ozone output is now in
acceptable levels.
These systems are fresh expensive than other air purifiers.
However, when you add in the cost of replacement filters, this
price difference curtailes over time.
The collection grid must be cleaned frequently. If it isn’t
clean, it won’t work. The frequency depends on the number of
impurities in the air. Homes with pets, smokers, a lot of dust,
etc, will need major frequent cleaning.
