Lennox X6675 MERV 16 Media Filter: MERV 16

Why it matters

The Lennox X6675 MERV 16 Media Filter is a replacement media filter for a whole-house air cleaner cabinet rated MERV 16.

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.

Fits, per the listing: Air Cleaner.

The Lennox listing names a carbon or odor layer.

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 16 here vs 11.

Questions buyers ask

Is MERV 16 right for my home?

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. If your system is old or the filter slot is a 1-inch return grille, watch for whistling or a filter that bows; those are signs to step down a grade.
