Love Blue Signature

Easy to set up and use. After a week truly feel the difference in our home. Bonus, it’s beautifully designed serving as an end table in the living room.

Does a great job!

I bought the air purifier specifically to deal with smoke from Southern California brush fires. Fortunately, we have not had any fires locally since the purchase. But it does a good job if my husband overheats the olive oil while cooking.

Clean air at last

The system was easy to start. (One of my daughters set up the app) We immediately noticed the air was cleaner. We have two dogs and two cats so how well it treats dander, etc we aren't completely sure of yet, but after the first few weeks, I am confident it will handle the load. The system is super quiet and attractive. All-in-all, I would rate our experience, so far, an A+. Very happy.
