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

I have 3 rescue dogs and keep it going in the living room 24/7. You should see the filter every week. It really helps as I have allergies

Theses after market filters are cheaply made . The originals have a foam charcoal filter these are a plastic looking open spongy type filter over the white filter. They wont catch what the foam type did at all. I wont buy again.

As others have stated, the FLT4825 filter is not compatible with Germ Guardian Air Purifier. The original filter has a plastic rim that snaps into the purifier. The filter I received has foam liners on the top and bottom of the plastic panel, which prevents the filter from snapping in place, and stops the purifier from turning on.

Didn’t fit my germ guardian and had to send back

These are great filters that really help keep our allergies under control.

Great product at a great price.

Bought these filters as replacements for Germ Guardian purifiers. Great quality and they fit perfectly! Thanks

Dont buy these they break germ guardian machines.

This is the perfect replacement for the brand name version, and bonus their frame is made out of cardboard instead of nonrecyclable hard plastic.
