Modified Zen

I've moved apartments since purchasing this for a larger open space. Yet I've managed to find a nook where it isn't overpowering the room. I use a rock to secure curtains stay away from it.With a cat who likes to perch herself on top of everything - having this air purifier oscillate keeps her from using it as a scratching post. Unfortunately (as others have written) it makes a lot of noise pollution. The screeching sound is just as bad for a zen household as any other pollutant.The heater is perfect to warm up a brisk morning or grey afternoon in 3 seconds. Helps keep from fiddling with apartment heater settings too.And being able to swipe clean the back filter is amazing... minimizing larger filter changes.Minimizing the oscillation screech would give this model a perfect ambience score.

Its a nice product to have at home

It’s a convenient all-in-one appliance to keep in the living room for the entire year. Whenever I see the PM2.5 level drop to zero, I know my kids are breathing clean air in a clean living room. The fan/ filtering function is good to keep the room with fresh air and cool. Don’t expect the heater function to instantly warm up your room like a traditional heater, but once you turn it on, the room temperature will rise to a comfortable level within 10-15 minutes. I understand that many people complain about heaters lacking timer settings, but I can live without it. However, it’s definitely a good feature to have. Last not least, the large size is really big, make sure your room is also big enough to place it.

Not a fan of it. Doesn’t seem to be working in my home. Has a small one and that worked better at odors than this one.
No, I would not recommend this to a friend.

It gives a homey vibe while also filtering the air well! I also really like that it has an option to rotate and is fairly quiet. Overall I'm very satisfied!

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.

Works well

It works well, although it sometimes gets turned around so it'll oscillate towards the wall, that might be due to it getting bumped into. The particle sensor is pretty reactive and the high blow settings move a good amount of air. I haven't had any regular intrusive noises like clicking or whirring, it's infinitely more quiet than my dehumidifier. I do wish it had active VOC filtration because you can still smell some strong odors. And for people who use this in their bedroom the dark mode shows basically no light so it won't keep you up. 👍

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.
