Veva HEPA Filter B Replacement, Compatible with Germ Guardian FLT4825 HEPA, AC4900CA, AC4825, AC4850PT, AC4820, Pack of 2 HEPA Filter / 8 Carbon Pre-Filters for GermGuardian Filter B

These filters from this company specifically (VEVA) are the only off-brand filters that work in the Germ Guardian air purifier. The certified genuine Germ Guardian filters can be really expensive so this is a great alternative at half the price. But dont buy the ones from other companies, they dont work. Or at least the couple of companies I have tried did not. Dont know about all of them. But really I would not trust off-brand filters for this product, it is very finicky. Essentially (depending on how bad the air is) these last for quite a while. I blow smoke into them and they have still lasted for months. Highly recommended!

These filters have worked well with our air filtering machine. They fit well, last as long as the originals, and we can certainly tell a difference a difference in how our air feels when we breathe it -- feels lighter and fresher -- and we dont smell our dog or cat anymore. We have one in our bedroom and one in the kitchen/laundry room area. The cats box is in the laundry room, and the filter makes a truly substantial difference in the stinky smell in that room. It really helps! I recommend them; they are the only replacement filters we purchase.

Have been using for several decades now. I run my unit 24/7 and replace the filters once a year. What I have found that works great is: I put two (2) carbon filters on the HEPA and not the one (1) as noted in the directions. Once every two-months I take the HEPA filter out, and remove the two carbon filters. The HEPA I tap on a flat surface knocking loose fine dust. The two carbon filers I first shake outside (much hair and dust comes off). I then bring the carbon filters to the sink and thoroughly wash. You loose some of the fine carbon but much crud washes out. Squeeze the water out and attach back to the HEPA filer, re-install back into the Unit and your all set. That double carbon filter back to back catches so much crud, it extend the life of the paper HEPA filter by a factor of 2 or 3X by keeping much dust now trapped in the carbon filters away from reaching the paper HEPA that would have clogged it...

Good price for new filters. We run the air purifier 24/7 in our basement and it works great. I like that I can order the replacement filters on amazon because they arrive so quickly.

I have tried 4 different brands for my 4 air purifiers because replacements from the manufacturer is so expensive. This brand lasts the longest, I can feel the different in my air quality compared to other brands and love the price. As long as you change out the carbon covers over filters every 30 days one filter will last 6 months with still great air quality. I have 2 dogs and 2 cats, lots of pet hair and dander, not to mention Im allergic to all 4 and a lot of environmental allergies, I cannot breath without these filters.

This is the best way.

This filter is a about half the price of the original filter, however it does include four carbon pre-filters per replacement filter rather than Germguardians single. The two fit fine in the air filter, just like the original. However, one concern I have is that the filter has 1/2 or maybe 1/3 of the number of pleats as the original. I dont have the equipment to measure accurately air flow throughput or filter effectiveness but it could imply this non-OEM filter wont last as long, or it might let less air flow through or tax the blower more. Next time Ill likely by one of each for a side by side seat of the pants comparison -- as it is, while I can say a new Veva filter seems to work better than the current old used GermGuardian FLT4825 filter, I dont know if that means much.

Good alternative at a lower price.

This filter kit is a great deal and product is great. I have two Germ Guardian HEPA air filter systems and I have used these filters several times. They work great and are easy to install. Highly recommended.

Cheaper alternative to the Germ Guardian brand. Works very well.
