I'm never without a replacement filter for my Bionare units because they just show up at my door right around the time the little light turns on. LOVE how easy that is!

I bought this to replace an old ionizer that I could no longer get new filters for. It takes up less space on the bureau and I noticed almost immediately that I'm not as stuffed up when I wake up in the mornings.

It’s a filter, you open up air cleaner and put it in. It works keeping the air clean with our 2 pups in the house.

Great product.... but

Reviewed in the United States on June 29, 2021

Verified Purchase

Machine does very well. Great product I even purchased a second unit but what I didn’t know at the time was the filters are very hard to find and when I found one it was $40+
I’m very surprised a Holmes product that works so well isn’t better supported. The unit is useless if you can’t buy replacement filters.

Does it's job great!

This machine and filters work great. I've had to change the filter more often than suggested but I think it's because we have a dog running around on carpets, throwing around toys, etc etc. Lol
