Filter too large

The filters were too tight and had to crush the sides of the filter to install.

I like the filters so far but the size doesn’t fit snug the door has to hold them in because they’re to lose for the frame to hold them in the casing and the 20x20 is the size I always buy but my door holds them up.

Great service for many years
It so easy not to replace filter on time
Put schedule that works for you. You’re notified and then shipped.
