The Lennox X8344 MERV 16 Filter Upgrade Kit is an upgrade kit for the Lennox PCO-20C Healthy Climate Air Purification System. This Lennox filter kit includes one MERV 16 filter, also known by part number X6669, and six UV bulbs, also known by part number X8149. The pleated air filter features a MERV 16 rating, which allows it to trap very small airborne particles and prevent them from circulating in your home.
The UV light bulbs utilize UVA light rays in order to oxidize contaminants in the air without using toxic chemicals. Be sure to replace these UV bulbs once per year in order to achieve the best possible results with your air cleaner.
