Lennox Healthy Climate # X8149 UVA Bulbs for PCO-12C / PCO-20C (Formerly 10M35)
Lennox PureAir UVA Replacement Lamp. The Lennox Healthy Climate PureAir replacement UVA lamp uses UVA light rays to oxidize contaminants in the air with no toxic chemicals. Lennox recommends that the bulbs be replaced once per year for optimum performance since the bulb effectiveness declines with use.
Note: The Lennox PureAir unit (PCO-12C) requires 4 replacement UVA lamps per year. The Lennox PureAir unit (PCO-20C) requires 6 replacement UVA lamps per year.
One side of lamp has opaque coating to prevent UV light from shining on paper filter
