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
versus the air	benefits. It should be noted that supporting tests,
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
electronic	amount of ozone, about 0.005 to 0.010 parts
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.
