Use a carbon Odors are gases, not particles. They cannot be
filter to remove removed by the air cleaner or by any other filter
odors designed to remove particles. However, some
gases can be trapped by an activated carbon
filter or diluted with outdoor air. If odors are a
concern, talk to your heating and air condition-
ing dealer about installing a carbon filter
downstream of the air cleaner or providing an
outdoor air inlet.
The electronic Air ionizers have been marketed with claims
air cleaner about purifying the air and promising medical
benefits. It should be noted that supporting tests,
versus the air
ionizer if available, are controversial and incomplete.
Air ionizers may generate a bit of ozone, and of
course some ions (air molecules with an electric
charge). This is what your electronic air
cleaner's ionizer does, but with greater inten-
sity. However, air ionizers do not have good
collectors, if any. With air ionizers, the charged
dirt particles are collected by walls, floor and
furniture, requiring frequent cleaning of the
entire building to remove the effects of collected
contamination. By comparison, an electronic air
cleaner deposits contamination on the cell(s)
and prefilter(s) for easy cleaning.
Ozone and the Electronic air cleaners generate a very small
amount of ozone, about 0.005 to 0.010 parts
electronic
air cleaner per million (ppm). The amount is highest when
the air cleaner is new.
The average person can detect the odor of
ozone in concentrations as low as 0.003 to
0.010 ppm. The U.S. Food and Drug Adminis-
tration, and Health and Welfare Canada
recommend that indoor ozone concentration
should not exceed 0.050 ppm. As a compari-
son, the outdoor ozone level in major cities is
sometimes higher than 0.100 ppm.
