Duck Brand Replacement Air Conditioner Foam Filter, 24-Inch x 15-Inch x 1/4-Inch, 1285234

Very effective at filtering airflow if to have pets, temps on tower didn't change.

Well, there is not much I can write about this filter. It looks like it'll do the job. Since the weather here has been below average temperature and I did not have to turn on my AC, I don't know how well the filter will work. I'll update my review in a few months.

Great find on Amazon. I needed a new air filter that I could cut to fit for a good price.Found it on Amazon!!!

These foam panels are great at blocking out the cold air in the winter. We just put them up with a little bit of duct tape over the plastic panels. Installation took about 10 minutes. It was slightly difficult to cut the plastic bars to shape (we used a bread knife) but the installation was fairly easy. We were able to just use 1 package of foam but if you have a big gap between the air conditioner and the window (on the left and right sides) you might need a second package (I saw some of the other reviewers were complaining about this). But 1 package was fine for us. I think it prevents some cold air from getting in but haven't taken a temperature measurement to be sure. Also I think you could get foam cheaper from other places (and just tape it up) but this wasn't a bad option. And more cost effective than going to the hardware store ($20 for the same thing).Overall good value for the money.

Though supposed to be used for air conditioners, I use this for alot of other things too, along with it's competitor, Thermwell Products 15X24x1/4 A/C Filter F1524 Air Conditioner FiltersThe ducky one is more fine, which means it will capture more dust, (you will also have to wash it more). I tried using it as an aquarium filter, along with the thermwell one, but the ducky one clogged too often, and i didnt need the water super clean, so i switched it's use to a computer fan dust filter. Let me tell you, it catches alot of dust, so every once in a while, ill vacuum it up and it will work brand new.This is also super durable, when I had it during a trial run filtering my mini pond, it withstood cold/hot temperatures, the sun, and also repeated hand washed, and still held shape.So depending on use, this ducky one has much denser foam and will catch more particulates then the thermwell one.As an air conditioner filter, it works great too, easy to cut, and when clamped on the edges, the foam squished together to form a nice seal-Cheap-effective in filtering-durable-large size

These insulating foam panels are quite a bit more brittle than I expected; the foam does give in to the touch, and is reasonably flexible, but it does feel more like a formerly spongy foam that has started to become brittle after a few years of exposure, and is about to break down. I don't know if the package I received is old, or if this is how the product is supposed to feel. Hopefully, it doesn't disintegrate in less than a few years. I suppose time will tell....

Perfect cut to fit filter!

Great replacement filter works perfect
