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

So big nice

The quality is great. It's a perfect mesh. Not too thin nor thick. I am using it as a air filter in my Epson projector

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.

The product should be rendered stiff.

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

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..

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!

This was perfect for replacing our dehumidifier filters. Just cut to fit.

This foam filter works surprisingly well for how inexpensive it is. It’s very lightweight and easy to cut into custom shapes or sizes, which makes it useful for way more than just air conditioners. I’ve seen people use it for AC units, space heaters, gaming PCs, air purifiers, and other devices that need simple airflow filtration. One of the best things about it is that it doesn’t noticeably restrict airflow. Since the foam is thin and porous, air still moves through easily while helping catch larger dust, lint, hair, and debris before they get pulled into equipment. That balance between filtration and airflow works really well for applications where thicker filters would choke performance. Installation is extremely simple. You can cut it with regular scissors using an old filter as a template, and the material trims cleanly without crumbling apart. The sizing is generous too, so one sheet can often make multiple replacement filters depending on what you’re using it for. The foam material feels durable enough to wash and reuse several times before needing replacement. It’s flexible, lightweight, and holds up surprisingly well after cleaning. The open-cell foam design also makes it easy to rinse out trapped dust and lint. Fit obviously depends on what you’re cutting it for, but because it’s so customizable, it works well in odd-shaped or hard-to-find filter sizes where official replacements are expensive or unavailable. The only small downside is that it can retain fold lines from packaging initially, but those flatten out over time or once installed. Also, because it’s a thinner foam filter, it’s more for larger particles and airflow protection rather than super fine HEPA-style filtration. Overall though, this is an excellent value filter material that’s versatile, easy to work with, maintains strong airflow, and works great for custom filter replacements and DIY projects.
