IQAir&#174 Chemicals List

Almost all of the chemicals below have a corresponding IQAir purifier which is recommended for the control of that specific gaseous contaminant. The most optimal IQAir model below is based upon light concentrations of these molecular contaminants, i.e. generally 10 PPM or less. In those cases, an IQAir model from the GC Series is recommended. If even greater quantities of carbon are required, then a model from the GCX Series should be considered which contain approximately 2-3 times more activated carbon than its GC sibling. These tests were undertaken by the media manufacturers.

* the IQAir HealthPro Plus alternative is only recommended for lower chemical concentrations.

** models with two asterisks beside them are not suitable for laboratory work.

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.
