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

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

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.

I have two of the Pure Guardian AC4825 Purifiers and change the carbon filters in them about once every 3 months. This 4 pack is perfect and fits without any problems or cutting. The price is also a lot better than buying the Pure Guardian ones.

I change this every month. Between dust, dog hair, etc. it gets pretty full by the end of the month. Seems to work.

Very easy to use and they work great! Thank you

I developed a late in life allergy to my cats. So I bought two air purifiers that have filters. As we know, filters are ridiculously expensive. The air filters I bought came with these carbon covers so I immediately ordered this box of 4. I would say I change them every 6-8 weeks (at minimum) and so far I have been able to keep the filter clean enough that I have not had to change it yet!

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.

These came in a plastic bag with holes punched in it. Carbon filters degrade when exposed to air. All the other brands I have purchased come sealed in plastic for storage until opened. I dont think Ill purchase this brand again, because there is no indicator that the filters are fresh when they arrive.

good service/delivery good product. thanks

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.
