Works as great as what’s advertised.

Blue air t20i works great. It’s truly what has allowed me to survive through the fire season and summer barbecues. I have been the owner of BlueAir purifiers for at least 10 years. I endorse their products with no reservations. I never need the old school wall heater, my Blue Air does it all keeping it cozy in colder temperatures too. Thank You!

3rd Replacement Coming
on September 15, 2026

Currently in the process of receiving my 3rd replacement for this air purifier. I can just start off by saying disappointing! Even, more disappointing because of the cost. My first unit wouldn’t stay connected to the WiFi and when it would oscillate you can hear it clicking. Received a replacement not even 2 months ago and only for this to happen again. My new unit will not stay connected to WiFi. Now instead of going through a refund they are sending me a 3rd unit. Horrible unit for the price and technology.
No, I would not recommend this to a friend.

Awesome

Purchased the smaller version for my sons nursery room and the bigger one for the living room and they work well. The fan is nice and the purifier mode is noticeably making a difference in my home. Haven’t used the heat mode since it’s summer but have tested it and it seems like it will work perfect for winter time. Overall great purchase. Happy with my blue air purifiers !

T20i had a noise issue Tech Dept evaluated the noise via video sent. The replacement was sent with old unit returned ,no problems. I ended up buying 2 more purifiers sc9 for bedroom with alarm they work great .I know if there was a problem this company will uphold and stand behind warranty. Jon (5 stars)

I love this thing!

I purchased this unit because it offers heating, cooling, and air filtration in one device, and I really love it. Some reviews mentioned that it makes noise when it oscillates, but I haven’t noticed that issue. It does produce a very low sound, but it’s simply the air filter running.I actually don’t mind the sound at all. At this point it feels more like white noise in the background. I’m very glad I decided to purchase it.

Works as expected.Wish BlueAir offered a floor stand for this model?!Would make cleaning the floor easier. No need to move the unit around. Thank you.
