20x20x4 filter is only 3. 5 inches
These filters are a full half inch less deep than advertised, and almost an inch less than the 3M filters I have been using. Pretty disappointing.

Questionable filter rating
Bought MERV 13 rated filter. Well constructed, however, I am doubtful of its MERV 13 rating. It has half the pleats of an equivalent 3M MPR 1500 filter. So either it does not filter the same micron size of particles out or it is much more restrictive due to smaller surface area. Either way it may not be a good filter. The MERV 8 filter has same number of pleats as the MERV 13, which doesn't make sense.

Very poor quality control. Pleats
Very poor quality control. Pleats are bunched together on the sides instead of being uniformly spaced.
