This is a great combination of devices. It replaces a cooling fan and a heater as it filters your air.
I would recommend this to a friend!

I Love my 3-in-1 T20i

I am very happy with the performance of the 3-in-1 T20i Air Purifier. I don't need to use it daily. When needed, a few months ago, I used it to heat the living room area instead of using my central heating which heats the whole house. I did however have to manually turn it off. I do not have central A/C for our somewhat mild weather, but have successfully used the 3-in-1 to cool my living room area when the weather has heated up. Because my living, dining and kitchen areas are not separated any walls, the 3-in-1 has done a great job of eliminating cooking odors. I have not seen a significant increase in energy usage.

We love our Blueair 3 in 1! Love how it moves air and tells the filter usage and can set a schedule.

It blows good...

Unit works great so far, the app could work a little better. When looking at the graph in app, you have to kinda guess what the exact # is that the dot is on. The Protect model actually shows exactly what it is in the app. I know it shouldn't matter the model since it's the app that is the issue but for some reason it's different. Haven't tried using the heat yet so fingers crossed i won't regret the purchase...

Amazing investment worth every penny so far

I was initially looking into big name brands for a 3 in one purifier such as Dyson, shark, etc. however, I found all those long term reviews lackluster. Then, I wondered if Blueair (who I already have several air purifiers for a few years now), made exactly what I needed. To my surprise, they did! I received it quickly and it was just as easy to setup/use as my other models. I’m excited to use it every day. The corresponding app is also well developed and really enhances its features. 10/10 would recommend.

Loud Ticking Sound when Using Heater Function
on December 20, 2024
Posted by: ad88
Verified Purchase:Yes
ticking sound when using the heater. about a few hours in using the heater, the machine starts a ticking sound. I use this during the night when I sleep and am always awake from this ticking. Also frustrating that the heat control cannot be operated by remote or app, so I have to roll out of bed just to turn it off. I will be returning this, do not recommend.
No, I would not recommend this to a friend.
Response from www.blueair.comBy Blueair TeamBlueairJanuary 10, 2025
We're sorry to hear about the issue with your 3-in-1! This does not sounds like normal operating behavior to us. We are sorry to see that you've chosen to return the device and we appreciate your overall feedback. For safety reasons, you cannot activate the heater through the app or the remote. We will pass this feedback regarding changing the heat settings along to our product development team for future consideration. If you have any concerns that we can address, please reach out to us directly and we would be happy to help.

Great purifier and fan

I enjoyed the fact that I can purify my house while using the fan to cool off our living room at the same time. It saves me space.

Air purifier!
on November 12, 2024
Posted by: lailahs
[This review was collected as part of a promotion.] I literally LOVE this air purifier! It also has features to warm up the area and also to cool the area. The sleek design is such a PLUS! Literally no noise what so ever, and also comes with a remote! I just had a baby so this is going to be so helpful to make sure there isn’t any poor air! I also love that it is a 3 in 1 product, to help minimize my apartment!
