Perfect fit. Cleans the air

Perfect fit. Cleans the air better than my other filters, a lot less dust!!!!
The cardboard framing bends from the power of the air flow and it was slightly deformed and difficult to remove. Just a slightly thick frame will take care of this.

Quality product at a good price sector to your home. My ONLY complaint. The 18x24x1 is smaller then frame. Consequently I have to jam cardboard between filter and frame.

Great filters
on May 7, 2026

These are great filters. MERV13 is one of the best grade of filter and these do the job. They fit well in to the return grille and catch most of the contaminants- dust, dog hair etc. I have them delivered on a schedule so I always have a replacement when needed.

Questionable filter rating
on May 4, 2026
Posted by: Customer
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.
