Says change filter when red light flashes. Red light continues you flash even after installing new filter. Why??

It works great Wish they were cheaper

Have used this in my mother in laws assisted living apt. She swears by it. Before she always felt she had allergies and it was dusty. Since we bought her this we have kept her in new filters whenever it tells us.

I compared the HEPA filter to the one I had bought years ago and it is the same high quality filter. It’s very easy to install obviously and it came in tip-top packaging. The carbon filter, however, is definitely useless to me. I bought a 4-set carbon filter pack and just used those. 4-stars because, to me, it is still very worth the price, but the carbon filter, again, is very flimsy and useless.

Fits perfect

I have used these for six years and I have no complaints

I have small apt and run in about 12 hours a day/night. It collects a lot of dust that I did not see on my tables. I change it more often than six months and I sweep filter every two weeks.

We have several Dogs and allergies. Item is easy to install and actually auto delivery makes it easy to know when to change out.

I love these filters. Solidly made, has some free installation, comes as 1 piece and does a great job. Also, these are longer lasting. Pricey but the quality is un-matched. Highly recommended

I 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.
