Friedrich KWCFM Carbon Filters - 3 Pack for Kuhl and Kuhl+ Series - M Chassis Models

Fit perfect

I have a Friedrich Window air conditioner. I feel that these Premium Carbon Filters are the best you can buy. They fit perfect and really do the job capturing allergens and provide superior filtration. They absorb odors as well. I would not use any other filters. They do a great job and you can see how much pollutants were absorbed when it’s time to replace them.

I used this to replace the original filter which just basically blocks dust. This seems to be working fine, no issue on air flow.

I ordered these for a friend who has an old Friedrich window unit and he needed filters again. I had order some before off Amazon that were also universal but the thickness wasn't as good as these which are OEM. We weren't sure on the size but I did look it up using it of the website and they are uncut sheets.

I don’t know if I ordered the wrong size but this is my units information so maybe they come oversized. I still was able to use it I just had to cut it with scissors to put it in. Other than that it works well.

Product: Friedrich KWCFM carbon filters - 3 pack for Kuhl and Kuhl+ series - M chassis models Rating: 5/5 (excellent) I got these to upgrade the no-frills foam screen filter, which does nothing but keep out the largest particles of hair and airborne dust. Likes: * Much better filtration - comparable to the outer prefilter wrap of a typical HEPA filter. The finer mesh captures much finer particulate than the porous default foam sponge screen, and the activated charcoal helps attract and trap a modest percentage of other fine particulates and a modest amount of odors too. * Can be easily cut down to fit smaller units, or to fit other applications (ex: microwave oven air intake ports, garbage pail odor eaters, etc.). * Reasonable value. Nits: * The one minor advantage of the old foam filter was that it could be rinsed and reused, whereas this cannot and is intended to be disposable and replaced on a regular basis. Its not so much a nit as identifying a trade-off ... for better filtration you need disposable filters, instead of something reusable. Recommended.

I gave it a five-star because it works good good quality but it's very expensive to keep using you have to change them every two months if the price was better I would buy more

Filter seemed to match the original one that came in my air conditioner and fit in terms of thickness. The package says it is Friedrich. However, I could not find one that exactly matched my model in terms of width and length, so I had to cut to size. I would rather not do this.
