15x24x3/16 A/C Filter

Yes this product is great for any air con. Remember this is a MERV 1- 4 rating that filters dust and pollen and animals fur. This is not 100% the best in air filtering but the UP side to this filter is it filters the air going through air con while allowing a greater volume of clean air thru and trapping some airborne particles. If you went for a higher MERV rating filter that does better filtering than this that would be a great idea but the DOWN side is that such filters restrict a lot of air volume flowing thru the air con because filter has to trap more tiny objects effectively thereby making your air con motor to over work and over heat resulting in either a break down or highigher electric bills. So please be mindful. For me, I prefer this one it is far better than the original filter that came with air con. I' ve spent £500 for my portable air con and not to allow simple thing like filter damage it or lead to higher electric bills. You should always strike a balance between air quality and and machine over load or air volume restriction. Good luck family.

I know this is intended for an air conditioner, but in my case that's not what I bought it for. I have a large dryer at home designed for use with dogs (it looks like a giant hairdryer on a stand but is much more powerful) and on the back of this was a round air intake protected by a circular sponge filter about 9cm in diameter. The replacement filters are both difficult to get hold of and, more particularly, ridiculously expensive for a bit of foam. So I bought this and am now in the process of cutting out lots of discs to make spare filters! It works perfectly well and the sheet is large enough to make so many that it'll last me years!

I used this to replace a clogged chainsaw filter. Really big sheet which can be easily cut to size.

Great product, using for my 220mm PC fan, no filter available, this does the job perfectly.

Excellent item

Exactly what was needed for our old Convair portable A/C unit. Many thanks!

Goods as described.

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.
