Wish the filter was a tad skinnier. When I slide the filter in, my unit causes the filter to squish and the cardboard on top bends upwards slightly. I can’t just check the filter because the filter tears, I have to remove and replace it

Well Made, good price

These are very well made and much more affordable than what is sold at the local retailer. I like that I can put these on a subscription that suits my needs. I have always rented and remembering to change the filters has always been a chore. I want my new home's a/c to work well, timely filter replacement is important for that and this makes it easier to do so.
