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

These were supposed to come with the other part of the filter for the air purifier!! I even asked if thats all i needed and I was told yes!!! The box part that the black filter is supposed to go on you never said i needed that as well!!! Now I have these black filters but the box part is missing!!! Thats not right at all!!!

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.

They’re ok, not original the ones that came with my air purifier are not as thick, they are softer, these work but seem to make my purifier noisier.

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

Price is good but too big for the filter so I recommend cutting it to fit the length. Also you should really buy the original hepa replacement once a year because it comes with the WHITE and the black filters that are meant for the filter to work well.

I have owned three of these air purifiers for a number of years. Very easy to use quiet and do a great job. I have ordered this one for a friend who has severe asthma.

Super easy to put in, works just like the one that came with the machine. very good value for the dollar.

it came with the fold.

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.

This is the best value for the pre-filters Ive found.
