1. What are the
main benefits that come with an air purifier?
Air purifiers benefit
your health by removing or reducing the occurrence of harmful
particles in the air. There are a variety of air purification technologies available at Air & Water to reduce odors, reduce particulates in the air, and to destroy living micro-organisms that float through the air you breathe.
2. What can an ionic
purifier do for me?
Ionic purifiers contain
a device that "ionizes" the air passing through it, causing the
particles contained to gain a charge (either
positive or negative, depending on the machine). After the air has
been charged, one of two things can happen: the particles in the air
can be attracted to an oppositely charged plate in the purification
process or the particles can be attracted to other particles that
have received an opposing charge resulting in the two particles
sticking together and falling out of the air. Purifiers that release
ions into the air have a much larger effectual range than those that
do not because the air does not need to pass through the machine to
start the purifying; air only needs to come into contact with the
charged ions that are released. Capture-type ionic purifiers only
need to be cleaned by wiping the dirt from the plates while ion-releasing purifiers require minimum maintenance.
The particles
are removed when you vacuum. Also, most ionizers are extremely quiet.
3. What does a
HEPA filter offer?
HEPA
filters use a cloth-like filter that is specifically engineered to
trap at least 99.9% of particles, 0.3 microns or larger in size. In
comparison, a smoke particle is 0.5 microns in size, nearly twice as
large as the particles that HEPA purifiers are designed to catch.
Because of this technique, HEPA filters can be extremely effective
in clearing out almost anything from the air in a room--just shut
the door and let it run. All filtration systems of this type have a
replaceable filter that can last up to five years, depending on the
environment being filtered. Although the noise level of a HEPA is
greater than that of an ionic purifier, it can usually handle a
wider variety of pollutants in the air.
4. Is there an
advantage in purchasing an active carbon purifier?
Active carbon
purifiers and filters use highly reactive carbon to chemically react
to materials as they pass through the purifier. By pushing the air
through the carbon, particulates are trapped and odors are bonded
with the carbon to hold them within the filter making for a very
effective process. Most activated carbon appliances use a HEPA
filter as well to provide the top quality, clean air output.
