Filters fit great, have been using this brand for over three years
I change filters every 6 months, don't use the HVAC that often.

Review filters

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.
