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

It goes to my air purifier that I purchased from you but I have not installed these are extra

These work great for what I use them for, and the price is super reasonable.

Right - These are JUST the carbon pre-filters, and they fit perfectly with my 4800 series, come in a neat little resealable plastic bag and cost about a dollar or so less than the other inexpensive ones. The reason I keep purchasing these is that they work - and they fit, and they dont smell weird or do any of the other things some reviewers say other brands/types do. We have both the 5000 Pet Series and the 4800 series, they are different sizes, so make sure to purchase the filters that fit your specific unit, but Ive now purchased these a few times and I have yet to be let down. Theyre even actually nicer than the original GermGuardian pre-filter. Yay!

I just changed my pre-filter after 3-4 months of use. I changed it based on time rather than a change in machine operation. It was extremely dirty; it looks like it did its job well. It protected the more expensive HEPA filter. Will buy more when needed.

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.

Easy to use, and has a uv light plus quiet.

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

Just what I needed

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.

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.
