Why it matters
The Lennox 19L16 MERV 13 Media Filter is a replacement media filter for a whole-house air cleaner cabinet rated MERV 13.
MERV 13 is the highest grade most homes use: it catches a good share of fine particles (0.3 to 1 micron), including much wildfire smoke, but adds more airflow resistance, especially in 1-inch frames.
This listing is the 16x25x5 size; order by the size printed on your old filter's frame.
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 13 here vs 11.
