Clean air
I bought it to clean the air in the house took a few days to get it linked to my phone but finally got it working. It’s a little complicated because I didn’t know how to set it but getting better at it. I think it’s a good product.

Great Customer Service
Honored my protection plan without an issue
They issued me a refund for the original cost in which I repurchased the same item.
I also purchased the 4 Year Protection Plan again because their customer service is outstanding 👏
