Filter Bros Carbon Filter C 4Pack Replacement Fits GermGuardian FLT28CB4 AC5250PT

Very pleased by these filters. They work great, fit my unit perfectly, and are a nicer quality than the name brand. Will definitely purchase again!

We have had our 3 Germ guardians for several years and they have continued to work quietly and kept our rooms safe and clean. We actually have 3 throughout the home! Filters and UV rods are inexpensive and easily installed! Only way to go. We have Kitty's and 2 pups, so we feel very confident in the product keeping dander under control!Easy to maintain and clean.

Consistency is good, thickness is good and cut to size, I compared this to the one that comes in my germguardian and this one is thicker,better quality, I also bought a large sheet of my own carbon filter and was able to make 6 sheets for 9.99, again the consistency in this one was better, meaning you hold it to the light and see a more consistent pattern across the whole sheet when looking at a light bulb so it is a better quality sheet and you don’t have to cut it, so you pay for What you get. I gave it 4 stars for value as they do mark it up a bit for those two things I mentioned considering I can cut my own for half the cost and get more(although not as thick) so maybe I’m just nitpicking...

I love the filter because the price was right and for me it last for 6 months. I suffer from allergies and it use to be they would come during late summer and last until the first frost. Now that I am older my allergies are lasting a lot longer. I appreciate the fact that this filter does exactlywhat is says it will do and keeps the air I breath clean in my home and free of odors that could make my allergies flare up. Very happy with my purchase.

I have tried to find company's that sell filters for a long time. I have the same filter in 2 air purifiers. Only length is the difference. Every company I have contacted could not give me the difference in sizes. It was like the same filter fit both of them. I almost bought a different air purifier because of the confusion. So, I went on Amazon (I love Amazon) to find a new one. I thought I would check and see if I could find someone that carried filters. I was surprised and I thought going through your company would be worth it. WOW. No fuss no muss. Thank you and yes they are working fine.

This is a knock off filter, not name brand. It is a little bit of a tight fit, but it’s do-able and it works fine. Lasts as long as the more expensive one. It is less expensive than the brand name, but honestly I think they’re all over-priced.

Great filters. When the Canadian smoke arrived, this filter kept the house clear from smells.

This is our third replacement filter for our air filter... always on time, always quality product... easy to install! We will continue to do business with this American based company!

I am very happy with my purchase. The quality feels way superior.
