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

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

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!

These carbon filters are half the thickness of original ones sent with the hepa filter 2 pack...not what I expected.

It’s super subjective to rate a filter without a control point. It might work. Didn’t die yet, so it’s alright.

Pleased

These organic vapor filters work pretty well. I have the air purifier in the basement apartment. The dog comes down here and sleeps on the couch and her farts (shes a fat black labrador) are devastating, but these filters quickly filter out her stinkbombs.

I like the way that it captures all the dust in the air. Works well with my Germ Guardian air filter. I dont notice the air being fresher though. With the way the carbon should work. Overall happy with this filter cartridge. Would buy again.

it came with the fold.

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!

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