Frost King Air Conditioner Filters, 15"x24"x3/16", Open cell foam

A very good substitute for the original which I could not get. After use remove the bobbles with the patting of cellotape. Thereafter soak in cold water and Savlon for 20 mins. Rince and dry out. It will be ready for use the summer after.

A window ac filter which can be adjusted / cut to fit any window ac. It is washable and does not interfere with the air flow.

Due to winter I haven't use it in my Ac ,will give detailed feedback after using it

It's what I needed

The item is very good and it's very useful in safeguarding the compressor of the AC

Full waste of money

lo utilice para añadirlo al splitter del aire acondicionado de la pared el tipico y sobro algo, no para repetir el corte..

Perfect replacement. Very easy installation. Each envelope contained 1 sheet of thin foam, which was more than enough material to replace filters in 2 of my through-the-wall air conditioners. This foam filter is thin; you can actually see through it. For cutting the correct sizes, I used the original filters as templates. With these new filters in place, my air conditioners are now working fine, blowing and cooling Dust Free. The new filters did not impede air flow.

This foam was purchased to limit the amount of dust accumulating in two fan heaters. After covering the air inlet grills - and emptying the barrel fans of fluff, the hot air out the front almost burns again! The airflow is unaffected, drawing cooler room air, at the back, over the internal, over-temperature cutout. That airflow is preventing it from cutting out prematurely! This foam has worked like magic!

I tried the purpose built filters on my computer fans but they just seemed to cut off too much air and there was still a lot of dirt getting around the CPU fan/radiator. The exhaust fans were pulling air into the case through unprotected inlets so getting stuff inside the case was still an issue. THIS, however is perfect as it is placed at ALL of the inlet openings where the fans get their air from. The front panel of my case has a layer of this between the metal case and the front cover covering the entire front of the chassis. As there is a much larger area for the filter to work, the fans are much more efficient doing what they are supposed to do. Instead of a fan dealing with a 120mm filter, it is using a much larger filter area. I put more material on all air inlets to the case using double sided carpet tape. The idea being that if ALL air inlets are covered whether they have a fan or not makes things so much better. None of the material is visible from the outside unless you look in the vent holes at the back of the case. They are easy to clean or for the price of the package, replace. I was considering buying a lot of these, repackage and sell them to computer owners for 5 times the price but I'm a nice guy. UPDATE, APPARENTLY AMAZON IS NOT A NICE GUY. HAS DOUBLED THE PRICE TO $22 WHILE EVERYONE ELSE IS SELLING FOR ABOUT $5. CAN'T TRUST AMAZON ANYMORE.
