expansive but effective, great filtration system to provide fresh air.

Love the product, quiet, size is great, convenient for placement according to operating guidelines, replace filters as recommended and should last forever. Keeps air clean, healthy .

Very good filter. It captures almost all of the dust in the air.

Awesome, really helps to keep our room air cleaner. You can tell the air purifier really works too and picks up on things quickly. In the mornings when I spray hairspray on my hair in the bathroom and walk past it in the bedroom it kicks into high mode to clear the air haha. I have the filters on auto ship so I never forget to change them. We have much less dust in our bedroom with this running and barely notice it.

Like the machine and like the ability to preorder and schedule replacement filters. Dislike the recent big price increase on replacement filters.Runs very quietly and seems to be effective. No longer rated as highly as other products on the market.

great bargain easy to install

They fit perfect

I bought this air purifier and associated air filters to get rid of the any unpleasant odors and allergens in my home, including any associated with my cat or her litter box, because I have family members and guests who have allergies.These filters worked so well that one of my guests said he would not even have known that I had a cat unless I had told him that I had a cat. He also said he is highly allergic to cats. So I consider this very positive feedback!I keep this unit in the foyer which is open to the second story. I keep my cat and her kitty stuff in a master suite (only one room away) on the first floor with the door shut most of the time, but not all the time, to keep her contained and because there is an intake vent right outside that door and I don’t want to spread her dander all over the house. I also have a smaller Leviot air purifier in the bathroom where her litter box is.
