Lennox 75X66 PureAir PCO-20C Replacement Metal Insert fits the PureAir unit size PCO-20C. The Lennox Healthy Climate PureAir replacement metal insert assists in oxidizing contaminants in the air with no toxic chemicals.

Lennox recommends that the metal insert be replaced every 24 months for optimum performance since the effectiveness of odor removal declines with use.

It is advisable that you change all three components of the PCO-12C or PCO-20C Healthy Climate PureAir Air Purification System - the UVA Lamps, Filter and Metal Mesh Insert every two years.
