Glasfloss21-1/2 x 23-5/16 x 1 Air Filters (Case of 6), MERV 10, Pleated, Made in USA

These were packaged great. Delivered quickly. And efficient.

They seem to be sturdy and fit well.

This was my second order of the Glassfloss a/c filters. They fit well and seem to do the job. I wish the frames were a little stronger, but I recommend them based on their cost.

Just purchased a New Carrier HVAC system. These filters are about 1/4 inch longer than the 2 included with my new system. I am traveling over the next 2 weeks, and will test adaptation once I return. Hopefully there will be no need to RETURN.

I have two Carrier units, and I thought these were about 1/2 inch too long because they dont fit... or so I thought.... I turned the units off to remove the old filter and put these in... dont fit... too long, no matter what I do. I could smash it in there, but that's not right... out of pure coincidence, I give up and turn the air back on and an unexpected thing happened. With the air ON, the filter is sucked into the hole just enough to push it in, perfect fit. Now I know, leave the air on, it goes in like a glove, air off, it wont go in. You're welcome!

Carrier makes buying their filters awkward and expensive since the sizes are odd shapes. I can’t say I would purchase these again from Amazon since the material is very fragile. They rip easily.

Easy way to purchase good quality filters in the hard to find size needed for my Carrier unit.

I'm very pleased with this brand or filters.
