Air Purifiers
Indoor air pollution can
be a big problem in your home, especially during
the winter.
Sealing up your home against the chill of winter
is a good way to save on energy bills, but it
could also keep stale air in, which can trigger
allergies.
So the Good Housekeeping Research Institute
looked at portable air-purifiers as a solution.
"The best models on the market are those
that use a motorized fan to move a lot of air
in and out of the room," said John Kupsch,
Technical Director Good Housekeeping Institute.
To help choose the correct size unit for your
room, look for a C.A.D.R. number on the box.
"C.A.D.R. stands for clean air delivery
rate and it's a certified number that actually
tells you how much clean air is being delivered
to the room," said Kupsch.
Another factor is the choice of filter material.
"One of the best filters on the market
is typically a hepa filter and this particular
filter also employs a separate carbon pre-filter
which is better for odor reduction and it also
has the pleated cloth to help filter out smoke
dust and pollen and pet dander. It has another
plastic filter that helps take out the large
particles. Other products claim to clean the
air using electrostatic means which is similar
to taking a balloon and rubbing it on your hair
and expecting the dust particles to be attracted
to that," said Kupsch.
Good Housekeeping says air purifiers that have
a hepa filter and electric motor proved to be
the most effective products.
They add that the C.A.D.R. ratings on air purifiers
range from 25 to 440; the higher the number,
the better.
