Great Air Purifier!

I was looking for a high quality air purifier and humidifier for our newborn baby. It's a must have as a new parents! I especially love the filter system and also how it looks :) It's very quiet so I almost forget it's running. I know Sharp is a trustworthy Japanese brand and I'm totally convinced it worth the money.

Breath of fresh air

I bought this unit after finding out I had several indoor allergies. After researching for sometime I deciding on this model. The first couple of days I really didn't notice it was doing much. Then I decided to rearrange my room and unplugged it for awhile. Few hours passed. I went back to the room and could definitely tell it had been off. I was astounded at the difference it made. I turned it back on and hit the quick clean button and my air was fresh once again! I would 100% buy this unit again.

Great air purifier

The air purifier works great! I was amazed after turning it on and coming back to the room several hours later to find how cleans the air smelled. The purifier is very quiet on low. Even on high it is not annoyingly loud. We have slept with it on high. The one thing I do not like is that you cannot put it right against the wall. The quality of the product is fantastic.

Awesome machine

I really like this air purifier. Earlier I used to suffer from allergies and stuffed nose in the morning, but after putting this machine in my room, I have seen huge improvement in my sleep quality and I wake up fresh in the morning.
