Customer Reviews for Frost King 15 x 24 x 3/16 Air Conditioner Foam Filter

I bought this to use as a pre-filter for shop vac filters. There is enough to make two and the joint is glued with PVC cement. The photos show how it was done.

Great for furnace filter..Great price and fast shipping

Easy to use for my camper to keep dust and dog hair from getting to the refrigerator and heater in takes

Just what I needed. Could not find it anywhere else.

Replacement for RV A/C unit. Cut it down to the perfect size. Done.

I needed this flat foam sheet to replace the seals in an auto distribution box - was a perfect application and fast delivery and fair price - could not find this in any other store but Home Depot

They are good filters

Simple product, does it’s job… Probably could be sold for less but no worries.

Works well, will buy again.

The filters were easily cut to fit and installed. I will buy them again

Filter material is easy to cut and customize to fit almost any window/wall AC unit. It's cheap and a throw away item with no need to wash to re-use.

had to trim for my application. works good.

Simply the best, easy installation

Just what you wood expect a foam filter that you can cut to fit a window unit or any other device that needs that type of filter media. Very inexpensive.

The Frost King filters have rescued my budget. Years ago, when I ran out of pre-filters for my HEPA air purifier, and my budget was at the "end of the month," I saw these in a local hardware store, and I decided to purchase them, since their job is to screen out dust and particulate matter. They worked just as well as the expensive filters. I still purchase them, since the cost of the pre-filters has skyrocketed. I will not go back to breaking the bank, when these are just as effective.

So far there working good hasn’t been long but there going to do the job.

The Frost King Window Air Conditioner Filter was and is perfect for my application. The size was generous enough such that I could cut and fit it to my air conditioner for a perfect fit. Thx

It served the purpose
