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

Im on my second order of these filters for the Germguardian AC4825 Air Purifier. Ive noticed no difference in performance between the replacement filters and the original filters that came with the unit. The extra carbon pre-filters seem to extend the life of the HEPA filter. Im in an old apartment building with boiler heat, so its especially susceptible to mold. Air filtration is a must.

Perfect fit for Germguardian AC4900. Filter material seems to be high quality. Im convinced all the oem and aftermarket filters are made in the same place :)

Have orders these twice. Works well great price

I love a deal and these filters cost half the price of name brand ones. They last just as long and come with more of the carbon pre filter which makes the main filter last even longer.

Extra carbon filter is really appreciated and useful. Filter works and fits great and price is awesome too! 10 stars!

Ive used these now for several years. Finally sitting down to write this, as you cannot go wrong with these. They send you several charcoal filters along with the main filter, so you have extra vs other companies that force you to buy even more. And they seem higher quality vs other companies too. Its really helped me with my breathing issues. I dont regret my purchases for one moment.

These are decent filters and at a good price. They include a coupon in the box for 50% off on their filters if you visit their web site. However, their site is down and hasnt come up since I started checking a few days ago. Thats why I gave them 4 stars instead of 5.

It works great like original one and less expensive. Even thicker than original one. I run my air purifier 24hrs 7 days a week to breathe clean air in the house and use it every rooms. I might purchase again when it needed to change but the company included extra pre filters so it will last me at least a year,. I will update when the time comes. Other buyers mentioned that it doesnt stated it True HEPA, yes it only said HEPA and dont know why. The company should explain clearly to make customers understand. Please update to make things clearly. Thank you.

Good alternative at a lower price.
