Air cleaners are great for allergies and dust control
If you are considering purchasing an air purifier for
your home there are a lot of factors to consider - this is
partly why there is such a huge array of air filters and
cleaners on the marketplace.
Our goal is to review the various types of air filters,
compare and contrast the main features of each method, and
provide articles and resources from manufactures and outlets
to help make your selection process easier.

Why are ionic breeze air cleaners so popular?
A recent study by the U.S. Dept. of
Agriculture found that ionizing a room led to 52% less dust in the
air, and 95% less bacteria in the air. These results indicate
that negative air ionization can have a significant impact on the
airborne microbial load in a poultry house and at least a portion of
this effect is through direct killing of the organisms. (the
inference from this study is that if it works well in a polluted
chicken barn, it should work well indoors).
How do air purifiers work?
There are different methods of cleaning
the air, most units on the market today combine a few of the
following technologies:
HEPA Filters
HEPA air filters are made
from very tiny glass fibers that are made into a tightly woven
paper. This creates a filter consisting of a multitude of very small
sieves that can capture extremely small particles, including some
biological agents. Once trapped, contaminates and particles are not
able to flow back into circulation, due to the highly absorbent
pores of the HEPA air filter.
Ionic Filters
As most airborne particulate matter is
positively charged ions, Ionic filters clean the air by creating a
negative electrical charge which attracts the positively charged
allergens. The units typically collect the particulate matter
on steel plates and are appealing to consumers because they require
no replacement filters.
Ultraviolet
Germicidal light air filtration
This process attempts to focus on
destroying airborne germs and microorganisms using UV lighting.
Activated carbon
filters
Carbon filter pores are
highly adsorbent, forming a strong chemical bond/attraction to
odorous, gaseous, and liquid contaminates. As air is passed
through these filters the carbon operates to collect the airborne
contaminants. Overtime these units will require replacement
charcoal as it gets clogged and contaminated.
Ozone air
purifier
Ozone is one of natures most powerful
oxidants and germicides known to man. Ozone oxidizes airborne
pollutants, then reverts back to oxygen, transforming polluted air
to pure and refreshened air.
