Carbon Activated Pre-Filter 4-pack for use with the Germ Guardian FLT4825 HEPA Filter, AC4800 Series, Filter B By Complete Filtration Services

These carbon filters came in a 4 pack for the GermGuardian FLT4825. HEPA Filter will last alot longer when using these prefilters. Excellent fit, and arrived quickly. Thank you Amazon seller for great service!

Well if you have to buy filters then this is a good brand. I dont know much about filters however i have used this brand numerous times with no issues. Of course in hindsight i wish i bought a filterless air purifier but in the meantime i will continue to use this product. Yes i will recommend.

Works fine but needs to be changed frequently. Like once a month maybe. Otherwise its gets blocked and the noise level increases

These are thicker than other filters I have bought before which is nice because it actually helps filter. Some filters I have bought are so small that they don’t really filter. These were definitely worth the price, especially since I won’t have to buy filters for awhile.

Good product for the price. I recommend using these filters instead of replacing the entire cartridge. Just clean and vacuum the cartridge with the vacuum hose attachment.

I bought this to go with the filter that it lists in the title but I had to cut it to fit the filter. Not completely compatible

This is my second order of these pre-filters. They work every time and always arrive undamaged and ready to use. I used to blow them off and keep reusing the same one but, for this price. Ill just keep buying fresh ones. These seem identical to the OEM ones but, way cheaper.

Just what I needed

it came with the fold.

Work well. Easy to install.
