4 Packs FLT4825 HEPA Replacement Filter B Compatible with AC4825 AC4300 AC4800 AC4900 AC4850, 4 True HEPA Filters & 6 Activated Carbon Pre-Filters

A great value for the money I would highly recommend this product.

These do not work with Germguardian HEPA Filters. They fit fine but my filter will not turn on with these filters installed. When I install the old filter it works just fine, the outer casing on these is cardboard while the originals are plastic. The appears to be two switches that have to be made up for the filter to function one for the filter installed and the other for the door shut. Can oly assume these filters do not trip the filter switch.

These filters were ordered as replacements for those on our two air filter units. They were installed as easily as OEM pieces,both the folded paper and the HEPA units.

Looks an works Great

The filter itself seems to be ok but I’m no scientist. The carbon pre filter is thin. Almost pointless to have it on there. You can see right through it and tears wasily. You have to have the filter unit inserted a specific way (even after installing with the arrows the right way and following directions on the package) or it will not sit correctly on the pressure safety switch. Time will tell how well these work. Used on a germ guardian.

excellent value

Very happy as it is what it is.

Took exactly 2 minutes to swap these out. Fit perfectly. Arrived fast

Fit great!

Great fit, easy change, piece of mind
