Lennox X6667 FAQs
Is the Lennox X6667 the same as Healthy Climate 100898-05?
Yes. Lennox X6667 is the catalogue number for Healthy Climate part 100898-05, the PureAir MERV 11 replacement filter for the Lennox PCO-20C air purifier. Lennox lists it as a nominal 21 x 26 x 4 pleated filter rated for 2,000 CFM. If the label on your old filter shows either number, this is the matching replacement.
What is the difference between the Lennox X6667 and X6669?
The Lennox X6667 and X6669 are both 21 x 26 x 4 PureAir filters for the PCO-20C, rated at 2,000 CFM, but the X6667 is MERV 11 and the X6669 is MERV 16. In Lennox's test data, MERV 16 media captures 95% of particles from 0.3 to 1 micron, versus 28% for MERV 11.
Does the Lennox X6667 come with the PureAir metal insert?
No. The Lennox X6667 is the pleated filter only. The PCO-20C's titanium dioxide metal mesh insert is a separate part, the Lennox 75X66 (21 x 26 x 1). If you want a filter and an insert together, Lennox's X8348 PCO-20C maintenance kit bundles a MERV 16 filter with the insert.
