The filters are slightly smaller than the sizes they say they are which makes them fit loosely in the air intake vent. Never seen this in any other brand.
Filters seem like they are decent quality but for some reason the 20x24 is actually 19. 5x23. 5 which means they dont fit snugly in the air intake vent.
I think it is the perfect filter. It isn't always easy to find this size in my area. I'm excited that I am now on an affordable recurring purchase. One less thing I need to worry about. Thank you.
Our Museum furnace room door requires a unique sized air filter. I was able to order the exact size needed; it fits so well that double-wing, flush clips were not needed. :blush:
