Why it matters
The Lennox X0445 MERV 10 Media Filter is a replacement media filter for a whole-house air cleaner cabinet rated MERV 10.
MERV 10 sits between the standard and allergy grades, catching more of the 1 to 3 micron range (mold spores, fine dust) than MERV 8.
Media cabinet filters are made for one cabinet family; match the maker's model number on your cabinet door or old filter, not just the nominal size.
Compared with the Lennox Healthy Climate X6670 (HCF16-11) MERV 11 Filter: MERV rating 10 here vs 11.
