4 Packs FLT4825 HEPA Replacement Filter B Compatible with AC4825 AC4300 AC4800 AC4900 AC4850, 4 True HEPA Filters & 6 Activated Carbon Pre-Filters

My GermGuardian air purifier will not even turn on with these filters in place. When I put the old filter in, it works immediately (but the old filter needs to be replaced, which is why I bought these). Do not buy.

Didn’t fit my germ guardian and had to send back

These are perfect and half the price of name brand

Liked the quality. Disliked the price.

WE LOVE OUR HEPA FILTER, and these filter packs are a great buy!

Keep room clean

Perfect fit Works as advertised

The FLT4825 HEPA Replacement Filters are an excellent choice for anyone looking to improve the air quality in their home or office. These filters are designed to remove a wide variety of airborne particles, including dust, pollen, pet dander, and smoke, helping to ensure that the air you breathe is as clean and healthy as possible. One of the things I appreciate about these filters is how easy they are to install. It fits my AC4300 GermGuardian perfectly. Simply remove the old filter and replace it with the new one, and youre done! The filters are also very durable and long-lasting, so you wont need to replace them as often as some other filters on the market. Overall, I would highly recommend the FLT4825 HEPA Replacement Filters to anyone who wants to improve the air quality in their home or office. Theyre affordable, easy to install, and incredibly effective at removing airborne particles, making them a great investment for anyone who cares about their health and well-being.

I purchased these as they are a little more economical compared to the Name Brand. They fit fine....I have 3 units and they all have these replacement filters and work fine. I am very pleased and recommend these to all !!!

These do not work with Germguardian HEPA Filters. They fit fine but my filter will not turn on with these filters installed. When I install the old filter it works just fine, the outer casing on these is cardboard while the originals are plastic. The appears to be two switches that have to be made up for the filter to function one for the filter installed and the other for the door shut. Can oly assume these filters do not trip the filter switch.
