IQAir Model Selection Chart for Gaseous Contaminant Control
Most of the below chemicals have a corresponding IQAir model that is recommended for the control of that particular gaseous contaminant. The selection of the IQAir models is
based upon light concentrations of these contaminants, i.e. generally 10 PPM or less. The tests were undertaken by the media manufacturers.

Important Note: Although specific IQAir models may be recommended for the control of certain contaminants, the manufacturers make no claim as to the specific air cleaning results that
can be achieved under the user's individual operating conditions. The actual indoor air quality improvements that can be achieved with air cleaning systems depend not only on the
system's performance, but also on factors which are specific to that indoor environment. Important factors which will influence the air quality improvements include, intensity of the
contaminant and its source, the size of the indoor environment, the operating speed of the system, the number of air cleaners placed in the environment and the state of saturation of the
individual filter elements.
* no laboratory test work
** the IQAir HealthPro alternative is only recommended for lower chemical concentrations
