I absolutely love this Air Purifier and I would buy multiple units BUT there is a drawback. Costway is the only manufacturer of this model Air Purifier and the replacement air filters are available here on this website and they are constantly out of stock, not to mention the charcoal air filter that is a 2nd filter for this unit. The charcoal one you can find on Amazon but not with just the charcoal filter. You have to purchase a white HEPA filter that you can not use in order to get the charcoal filter. I wish Costway would have a package deal for the white HEPA filter for this unit and the charcoal filter for this unit available for purchase, but they do not!!! No this unit is on clearance it will be more difficult and eventually you will not be able to use this model unit once you can not find any replacement filters for it!! This is so frustrating and wish Costway or even Amazon would make this available to the consumer. If it were not for this one factor, I would purchase 2 more units of this model! I actually do love the unit but eventually will become useless!!!!!

We got this air purifier for our baby's room, just to get rick of some dust and odors. We've been using it for a month now, and it works great. This one has a safe lock, very helpful, since the baby likes to touch a lot of things. And you can adjust it to different modes, we usually use it in the daytime.

This is one of my best item for home essential, it purify air without making noise. Air purifier cover almost all my apartment 800sf.

This product saved my respiratory problems and I love the air in my room now.

This air purifier works well, I love the size not too big and not small, it’s the perfect size. I appreciate the child lock selection, (for those of you who have toddlers who loves to press buttons) this is a must! The sleep mode is so quiet which is my favorite part in finding a good air purifier.
