Lennox X6664 FAQs
Is the Lennox X6664 the same as Healthy Climate 100898-04?
Yes. Lennox X6664 is the catalogue number for Healthy Climate part 100898-04, the PureAir MERV 11 pleated filter for the Lennox PCO-12C air purifier. Lennox lists it as a nominal 17 x 26 x 4 filter rated for 1,200 CFM, and describes it as an alternative to the standard MERV 16 filter for that unit.
What are the actual dimensions of the Lennox X6664?
The Lennox X6664 is sold as 17 x 26 x 4, but Lennox lists its actual size as 16.53 x 25.90 x 3.93 inches, or about 16-1/2 x 25-7/8 x 3-15/16. Because the real size is slightly smaller than the nominal one, order by the part number on your old filter or your PCO-12C rather than a tape-measure reading.
What is the difference between the Lennox X6664 and X6666?
The Lennox X6664 and X6666 are both 17 x 26 x 4 PureAir filters for the PCO-12C, rated at 1,200 CFM, but the X6664 is MERV 11 and the X6666 is MERV 16. Lennox calls the MERV 16 the standard filter for this unit. In Lennox's test data, MERV 16 media captures 95% of 0.3 to 1 micron particles, versus 28% for MERV 11.
How often should I replace the Lennox X6664?
Lennox recommends annual replacement of the X6664 filter in the PCO-12C, but in most homes we recommend replacing it every 3 to 4 months, and sooner with pets, renovation dust or heavy heating and cooling use. Lennox's PureAir homeowner guide also calls for routine maintenance at the start of every heating and cooling season.
Does the Lennox X6664 come with the PureAir metal insert?
No. The Lennox X6664 is the pleated filter only. The PCO-12C's titanium dioxide metal mesh insert is a separate part, the Lennox 75X73 (17 x 26 x 1). If you want a filter and an insert together, Lennox's X8347 PCO-12C maintenance kit bundles a MERV 16 filter with the insert.
