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

I needed replacement filters for my Germ Guardian air purifier. I, accidentally, ordered the wrong size so it’s my mistake. I’m confident the filters are good; they just won’t work for my purifier. It’s a shame but I have only myself to blame.

works well

Great fit, easy change, piece of mind

Go.of. Deal and on time

They are not long enough to make contact so that they machine will run.

Good product

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.

Used for my germ guardian air purifier, no problems

Buy, buy, buy!! Get these ASAP!!!! They are just as good or even better than the name brand. HUGE money saver!!

Nice buy for my air purifier. Seems to do the job so far. They did got my machine perfectly.
