Allergy Air Filter for
People with Asthma and Allergies
Why do people
who suffer from asthma or allergies should get an allergy air filter?
Air quality is
a very important aspect for those who have asthma symptoms or allergies.
newspapers report daily air quality for cities around the world using
the Air Quality Index (AQI). But did you know that air quality in the home
and office can often be worse than the outdoors?
quality inside of homes is worse than outdoors? How is this possible?
are built to be much air-tight than decades ago. The
purpose is to reduce air leakage in the house to maximum the loss of
heat. This will reduce heating and cooling costs.
air-tight home can suffer from poor air quality because the air inside
is trapped. Dust, dirt, lint from bed sheets, pollen, human skins and
animal dander have no place to escape. If the floors, surfaces and air
are not constantly removed of these allergy-inducing particles, they can
worsen asthma symptoms and allergies.
For example, carpets
attract like crazy dirt, dust, dust mites, dust feces and many
allergy-causing stuff. No amount of vacuuming with even the best vacuum
cleaner will ever
remove all these substances from the carpets.
Experts even recommend removing
carpets and replacing them with laminates or hardwood flooring for
those who have severe allergies or asthma conditions.
floors, a simple wet mop will capture and trap ALL particles.
Unlike the carpets, the particles have nowhere to hide; they just rest
on the surface!
really that much dirt in the carpets?
is a very simple to prove to yourself. If you have one of those bagless
vacuum cleaners with a see-through plastic collecting unit, you can
actually SEE the dirt you pickup. Scary,
to say the least.
another way to prove to yourself that your bed sheets and pillow can
generate a lot of lint and dusts. When there is a bright stream of
sunlight shining into your bedroom window, get a pillow case and give
it a good punch.

viruses will go through a HEPA filter as many of them are smaller than
0.2 microns. For asthmatics and allergy sufferers, this is not a big issue. You
are looking to keep the air quality high and not trying to sterilize the
What about ionic cleaners or electronic cleaners?
Avoid them! Many
of these types of air filters produce ozone which can be irritating to
the lung in some people. This is especially true for those who suffer
the talk of using Ultraviolet (UV-C) to kill germs?
UV-C is used
to kill germs and viruses by damaging the DNA (genetic material) of the
germs. Damaged DNA means that the bacteria or virus are no longer able
grow and infect us.
UV-C light is used to kill of surfaces in microbiology labs. The UV-C lamps are turned
on for many hours when there is no one in the room (as exposing skin or
eyes to UV-C will cause serious damage!)
They do not work in air filters to kill the germs in the filtered air.
Why not? Because the
air flow is so fast (needed for better filtration) that it doesn't allow enough
time for the DNA to be exposed to the UV-C light!
You could improve UV-C's ability to kill off germs but then you'll have
to slow down the air flow to increase exposure time. This means very
little air will be filtered.
In the use of UV-C to sterilize countertops in the labs, remember, the
light is left on for hours (often overnight!) and the countertops
do not move and gets continuous exposure.
Choose a HEPA
air filter unit. Second, choose one with enough air flow to properly
clean the room. Getting too smaller a unit for a large room will result
in very poor air filtration. Of course, getting an oversized one for a
small room is great.
