Highly recommend for allergy and odor control

I’m really satisfied with my purchase and would highly recommend the Core 400S. I did a lot of research for an air purifier with deodorizer. I have allergies plus 2 cats. Within a few short hours of receiving and setting it up my runny nose stopped and the house smelled fresher. I purchased a Core 300S right afterward for my bedroom. Great product, easy to use and set up the app, and attractive as well.

Not a waste of money

I've had this purifier for about a week now. It makes my room feel crisp and fresh by moving stagnant air around and replacing it with purified air. The best part of this purifier are all the smart functions. It connects to my phone so I can control it from anywhere in the world. And the PM reader is super useful. Definitely not a waste of money.

Verified Purchase

I did not even unbox my Levoit air purifier because I bought it for my new grandchild's room. I chose it, however, after much shopping comparison and a strong recommendation from a friend who has two in her house.
