Air purifiers remove allergens, odors, and pollutants from
the air. They range in size, function, design and
price. With so many options and brands, deciding the best air purifier for your needs can be
confusing. We offer the best ozone-free
air cleaners that address a wide variety of needs including smoke and odor control, allergy, asthma,
multiple chemical sensitivity, and air quality issues like
pollution, cigarette smoke, pet dander and dust. If you are considering your first air
purifier, read our Air
Purifier Buying Guide for more information.
Air Purifier Technology
are many types of air purifier technologies. HEPA filters remove 99.97% of all airborne
particulates like pollen, dust, and animal dander. Many of the air cleaners we offer use activated
carbon to remove chemicals and odors. Combining both a HEPA filter
and a carbon filter provides the most effective air cleaning filtration.
Manufacturers vary on the technology used to clean the air we
breathe. In addition to HEPA filters and granulated carbon filters,
several manufacturers go a step further and use ultraviolet light and even photocatalytic oxidation.
UV light can be used in addition to HEPA and carbon filter
technologies to eradicate bacteria, viruses and mold spores. UV light, when paired with
titanium dioxide, can safely and effectively oxidize a wide array of VOCs, smoke and chemical vapors. And regardless of
the manufacturer, none of the models we carry produce any ozone, that also means all of the UV models we offer are
ozone-free as well.
Some manufacturers implement pre-filters in conjunction with the other
filter technologies mentioned above. Pre-filters extend the life of
the HEPA filter and increase air cleaner efficiency by trapping larger particles before they get to the
primary HEPA filter. To Buy Replacement UV Air Purifier Bulbs for
the current selection of UV air purifier models we offer.
Additionally, manufacturers use electrostatic or electronic filtration technology. Electrostatic air cleaners use
very small levels of positively and negatively charged particles to attract particles to collecting
plates or filters. For example, airborne particles entering an air purifier are positively charged;
and, the collection media is negatively charged causing the two to attract to one another. Manufacturers like
Blueair have ionizers built into their units, but
these are features that are not primary to their air filtration process. Other units, like
3M air purifiers, rely solely on electrostatic filters as an inexpensive alternative to
Another process used in air purification to clean the air is called ozone generation. We recommend avoiding this technology. We follow
the Environmental Protection Agency's guidelines which state that ozone generators should not be sold as air cleaners. We do not sell,
recommend, or endorse ozone generators.
Air Purifiers for Allergy Relief
Air purifiers help allergy sufferers by removing allergens in a room specific environment. We
recommend starting in the bedroom since people tend to spend more time in this room than any other in their house. Air purifiers
only remove airborne contaminants and allergens. Particles that are heavier
than air should be removed with a quality HEPA vacuum cleaner. Particles that are lighter than air include pollen, mold spores,
animal dander and dust. These particles can be effectively filtered from the air in your
home by using a quality air purifier. HEPA filters are essential for proper air filtration. A HEPA filter removes
at least 99.97% of all particles as small as 0.3 microns, though some of the air purifiers filter
particles as small as 0.1 microns with up to 99.99% efficiency.
Air Purifier Air Exchanges
A quality air purifier operates efficiently and quietly in a one room environment. To be effective, an air purifier
must have a motor attached to a fan that draws air into the unit. Once the air is pulled into the unit, it is filtered through various
types of filter media. Clean air is released back into the one room environment to start the cycle all over again. The amount of time it
takes and air purifier to cycle through all of the air in a room is referred to an "air exchange."
The more air exchanges per hour, the better air quality in the room. The number of air exchanges is determined
by two things: the cubic volume of a room and the cubic foot per minute (CFM) output of the air purifier. More air exchanges will
result from a smaller room and a greater CFM output. Ideally, we would like to see between 4 and 6 air exchanges per hour. There is
no such thing as overkill when talking about air exchanges. The more air moving through the unit; then, the more the air purifier
will filter the air.
