AC Safe EconomyPlus 15 in. W x 24 in. H x 1/4 in. D Polyester Air Conditioner Filter-Total Qty, 1 Count (Pack of 1), Gray|Grey

Recently purchased a true “ thru the wall” or “ built in the wall” air conditioner.It’s been working nicely but the filter that comes with it is constantly making the “ clean filter” light come on.We have cats and allergies to all the awesome stuff outside as well as some indoor allergies.Whenever the check filter light goes on ( once every 7-10 days) - there isn’t a lot of stuff in the original filter that came with the AC. But I do see some cat fur.Anyway, we only run the AC about 8-12 hours a day. I vacuum 3x daily because allergies. And some OCD.This white filter is interesting. You can see a lot better, what it’s catching, as opposed to the black filter.It cut easily, and I slipped it on top of the filter that came with the ac to hold it in place. ( hope that’s not a “no-no”.The filter us a woven nylon material. I’ve attached photos because it’s hard to describe.It’s thick, and someone else’s review complained that it isn’t 2-ply like the photo. It feels like it would be itchy if you had to wear it. Wish I could explain better.The photo that is shown on the product page is demonstrating that there are 2 layers blended together. You can not peal the layer up like they’re showing.Anyway, the filter works very well, in conjunction with my existing filter, which is a very thin ( like paper) mesh.This filter is the full 1/4 “ thick.It’s catching stuff for sure, but it hasn’t been in long enough to trigger the “ check filter” light yet.It’s doing a good job because I do see what it’s catching. It’s doing what it should.It did not have a chemical smell at all. It didn’t smell at all. Some people said it did. I was concerned since any weird smell can trigger my allergies.Content with this product. It wasn’t expensive at all. Recommend.

Used as a replacement for a worn out washable filter in a combination heating & cooling window unit.Easily trimmed to fit the old filter frame. Works quite well. Would definitely buy again.

But it works well once fitted and I'm thinking easy to wash and reuse at least one time.

I originally purchased this because the front of coil on my window heat pump was making it clear the included mesh filter was letting too much through. I use this now in front of the included filter, and vacuum it out at the same time, and it appears to be doing the job.I also use this as a pre-filter for a Hamilton Beach air purifier ( https://www.amazon.com/gp/product/B00EIDFSE8 ) that lacks one.UPDATE: I originally discarded the filter after it started to turn grey after being vacuumed, but I discovered that if I washed it using the knit/delicate cycle on my washer, it came out looking like new. I've only done this once for each filter so I can't attest to how many cycles it will endure, but it definitely lengthens the useable life of the filter.

I purchased this one, and just in case it didn't work, I purchased a more well known brand. A month later, I opted to buy another of this product because the well known brand didn't cut it for me.This filter is easy to clean, easy to hang to dry, quick to dry and overall, the best choice for us. We use it in our window because our neighbors smoke and use scented logs year round. It doesn't cut it out completely, but it helps.I will be purchasing more, but so far, the two I have don't need to be replaced. They are washable and reusable, just as advertised.

It worked good for the time I had it. Probably a little too small for my area. Only needed it for a couple weeks till my central A/C was installed.

i work in a dirty metal fabrication factory. i look forward to coming home and sitting in a clean air conditioned environment. these are absolutely perfect for my window unit, they dont have a noticeable effect on air flow yet collect a lot of the b.s. floating around at home. very easily washable. i would recommend these to anybody with an ac unit, especially considering the price! im using mine on top of the factory "mesh" filter that came with the ac unit. highly recommend!

Cut it to size for my window air conditioner- working great

good. I used it to cover the central air con.

Exactly what I needed for my ACs. I have 3 without filters. You can Cut to your own size

worked as expected

People be aware! This will not help reduce smaller particles / dust for condo. Maybe it works for very large ones but in my test, it did nothing to my condo's air conditioning unit when covering the air outlet. The dust still accumulates really quickly.
