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

Very easy to use and they work great! Thank you

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.

If you think this is a replacement for the one that comes with your air filter you are wrong. This is filter cloth but it looks as though someone free hand cut it with scissors including the wrong angles and thin pieces hanging on the side from bad cuts. they also do not have the Velcro boarder that sticks it in place. does it get the job done yes. Other side is look how much you are paying for it because thats what you would be getting for that price. Works, ill probably buy it again but dont expect perfection.

The description is somewhat misleading as this is not a four pack but one large sheet which can be cut into numerous filters. It looks like you can get 10 filters out of this one sheet but you have to cut it with scissors to match. I took the old filter out, lined it up on the sheet, cut it and then placed it on the Velcro that exists on the inside filter. It’s easy to do but first I was confused so I wanted to write this review.

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

Easy to attach. I am able to vacuum it clean and only have to change it every third month. I vacuume it the month after changing. Easy to do but I did put tape on edges to make it last one more month before changing. These pre filters are inexpensive and worth it.

Work well. Easy to install.

The filters were folded into half. There is no way to smooth the folded winkles.

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.
