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

Easy to replace

Should come in a roll and then you cut to height. The 1/4 inch mesh pr-filter was the right width but each was about 1/2 the height needed to fit on my primary filter. (took two). It would be nice also if they included a roll of double-sided 1/4 inch adhesive to adhere the pr-carbon mesh filter to the primary filter. Had to use some I had on hand.

They do not last long so i am looking for the same quality for less money

Needed for my germ guardian hepa filter. It was a great buy

Fits as intended but feels a bit different than the stock one and doesn’t stick as well to the Velcro on the machine but works well

Exactly what they advertised.

Very easy to use and they work great! Thank you

Product arrived day before expected delivery. These prefilters are for my Germ Guardian Air filter. They are a tiny bit bigger and a little thicker but fit fine. Very happy with them.

I like the way that it captures all the dust in the air. Works well with my Germ Guardian air filter. I dont notice the air being fresher though. With the way the carbon should work. Overall happy with this filter cartridge. Would buy again.

These are nice and cheap, which is great, but before you buy these, try washing the one you have off under the sink. If you are careful, you can probably reuse the filter a few times.
