Quality replacement filters
Caitlin—November 8, 2025
Not only do I like the air purifier it goes in, but the replacement filters couldn't be easier to install. You can clearly see in the picture the before/after and the fact they are good quality and look good/fit well. This filter has helped regarding my allergies in a new environment to make the air in the rooms much less filled with partials and dander. They do not have a smell, so it gives me reassurance they are clean. Read more

Work well- very tight fit- extra carbon covers for filter
douglas lowe—May 28, 2025
They work ok and I like the extra filter covers. The only issue is they’re hard to install because of a tight fit. I’m sure the brand made for my purifier work a little better but the price on these is good for what they are Read more
