> 3 dayWe have cats and kids that go in and out all the time, and we are always coming and going ourselves. lots of dust and dander. So, we have 3 air purifiers running constantly. I ONLY use these filters in my purifiers. They are the BEST! and keep the dust and odors to a minimum :)

> 3 dayI got my Germ Guardian 6 months ago and just recently my red light came in to change the filter. I was looking at the reviews on Amazon and saw that there were mixed reactions. I still purchased because some were positive and the price was better than other places! I’ve tried to touch on some of the concerning reviews I’ve seen and how my experience was similar/different. Packaging: The package appeared to be just as expected. Change in appearance: I saw a review that talked about how the filter Looked different and could be a knock off, but this doesn’t seem to be the case. My filter looked like it was good quality and there was an insert that talked about how the product was just redesigned to be efficient so it may look differently Installation: Installation was super easy and the machine had helpful labels. Frequency: I now know I should have been cleaning the black filter (not the white accordion filter) monthly so I’ll begin doing that. It recommends changing the entire filter every 6 months which is right when the light came on. Red to Green Light: I saw someone post that their light was still blinking - After changing the filter just hold down the UV button for about 5 seconds and it will reset the light. Overall, works great and many of the concerns I had previously from the reviews ended up being manageable! Save money and just purchase from Amazon. You can even set up automatic delivery for 6 months.

> 3 dayIt takes out a lot of the dusty air we have in Yuma. Maybe not all of it but sure enough there is plenty in the filter. Thinking about having one in the bedroom too. Not real quite but its doing its job so..

06-04-2025I have a Germ Guardian Model AC4825E, so I purchased this replacement filter for it. This filter fits my unit perfectly. It took about 15 seconds to install, and my unit turns on and off just fine without any problems. It is necessary to hold down the UV button for about 5 seconds to reset the flashing warning light to replace the filter. This replacement filter is performing well and seems to clean and deodorize the air just as well as the previous filter. Overall I’m very happy with this product and I will order more when I need them.
