Like it. works very good.

Easy to use and match with current filter

Excellent filter, it comes with a heavy duty internal filter that last 2 to 3 months, and then it has an outside carbon filter that you have to change every 30 days. Anyone that knows anything about carbon filters knows that they don’t last in most environments more than a week to 10 days. It does pick up an incredible amount of dirt and dust. However, you have to change that filter minimum every 30 days, i.e. the charcoal filter. I have another heavy duty filtration unit that I bought during Covid, three times as expensive and about 4 to 5 times better filtration. This filter change out will cost you $40, a more expensive piece of filter change may cost you $50. this is a fairly good filter machine and I would not hesitate to buy it. However, if you’re looking some thing to pick up as much viruses and Covid as possible, this is not the right one however, it helps immensely.

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.

Air filter

I put the new filter in and the red light keeps flashing. Why is this?

I bought one of these a couple of years ago. It works! I have now added another one. Its giving me just as much help as its big sister. Same model.

Works well with our Germ Guard air purifier

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

I was cutting up regular filters and using them for a long time; you can use a paperclip and strong tape to trip the little mechanism that prevents this, but over time I wanted to go back to the proper HEPA filter. More expensive sure but so much less trouble than cutting through those other filters and taping everything in to place.
