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

So, let me start with a little background. I have 2 dogs and 2 cats at home. The dogs track in a lot of dust from being outside and we have 2 litter boxes constantly in use. So my air purifier is constantly working. Anyway, i ordered this 4-pack to replace the single black filter that came in the original. These ones were definitely thicker and the size was *almost* the same. These were about a centimeter too long. However, i used regular scissors and then they were perfect. They seem to be working just like the original. It still sucks in the odors, fur, and dust like the original. It already has a tan color on it because of all the dust and its only been a few days. (yuck!) Overall, this is a great deal and just needs a minor and simple modification. I dont think spending 3x more for the other filters would have been worth it. Overall, Id recommend.

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.

Work well. Easy to install.

The unit covers my entire lower level of my home which includes the kitchen living dining room and sunroom, its a very powerful device. Great product for the price.

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.

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

it came with the fold.

Bad thing is to small for my machine, maybe was bad measured in the supply.

Price is reasonable for a filter. An original one from GermGuardian is slightly overpriced. Red light was blinking after three months. I checked a filter. There were lots of dust and small light bright color particles on a filter. Check a photo. e.g.) I vacuumed my room every two weeks, so I didnt except there were lots of dust in my room I detached an original filter and replaced it with a filter by CFS. It was slightly longer than an original filter, but it did not have any problems for installment. After the replacement, I pressed a UV button for 3-5 seconds to reset a indicator (red to green).
