This is a great little portable air purifier. We put it in my husband‘s new small office and it works perfectly. It works very well at cleaning out our air. We live in an area with a lot of airborne allergens so this has been great. I like that it is easy to move around and clean the air. It is easy to change out the air filter. I love that it has a night mode when I put it in my daughter’s room so there is no bright light or anything to keep her awake. I think this will last us a long time, I highly recommend it!
