Product Information

GermGuardian® FLT4850PT HEPA with Pet Pure Treatment GENUINE Replacement Filter B is a combination filter. It includes a HEPA filter that captures 99.97% of allergens as small as .3 microns. It also has a PetPure™ Filter Treatment, an anti-microbial agent to inhibit the growth of mold, mildew and odor-causing bacteria on the surface of the filter. The pre-filter/activated carbon filter layer captures odors from cooking, pets and smoking. It is recommended to use with the GermGuardian® AC4300, AC4900, AC4825, AC4850PT, CDAP4500 PureGuardian® AP2200CA and Black+Decker™ Model BXAP148. The use of this genuine Guardian Technologies™ replacement part will maintain the product's performance.


  • HEPA Filter captures 99.97% of dust and allergens as small as .3 microns such as household dust, pet dander, mold spores and plant pollens.
  • Charcoal filter layer reduces common odors from pets, smoking and cooking. Acts as a pre-filter to capture large dust particles, helping to extend filter life.

Replacement filter for GermGuardian Air Purifier Models AC4900, AC4825, AC4850PT, CDAP4500, AC4300; PureGuardian Model AP2200CA and Black+Decker DXAP148

Only one single combination filter needs to be replaced every 6-8 months depending on the use of the product; Charcoal replacements can be purchased separately to extend the life of your filter (Model #FLT22CB4).

Fits nicely and works well.

Excellent filter.

This filter is great for pets. I out it in the room with the cat litter box, and I can't even smell the cat anymore. Definitely ordering more.

It's the factory replacement

Factory replacement. So far its just as expected. Comes in factory box, and works just as advertised. Would recommend especially for the price compared to elsewhere.

Fits, works, wish it cost less

An OEM filter, so of course it works. . . just wish it cost less.

I've had no problems with the filter unit, so I recommend Germ Guardian to friends.


Wonderful filter

This us so easy and works so well. I have replacements when u have to change. Also so easy to clean once a month.

Costly but worth every dollar...

I had to get air purifiers in my apartment due to my downstairs neighbor who smokes like a chimney indeed. I don't how one woman can go through 5 cartons of cigarettes within 2 weeks which means 10+ cartons per month. She has lost her right leg (amputee) because she refused to take treatments that would help her to save her leg due to poor circulation. My Germ Guardians purifiers are on HIGH & my ceiling fans are always on if not I won't be able to breathe in my own apartment. Oh well that's life, but this filter is a MIRACLE worker for me. Thank you God!
