Review: Great & stylish 3-in-one purifier, fan and heater - We’ve had this about a month now. It is easy to use and is effective at warming up a room. The purification function seems to work well and the app lets you know key measurements like air quality, temperature and filter life. We like the clean modern design and quiet operation. When oscillating, there is a slight and faint knock noise as it reaches the end of the desired oscillation angle but after a while you don’t notice it. Assembling the device was simple and was just removing some the plastic protective wraps and installing the filter. The heat function was nice to have this winter as it helped supplement the HVAC and keep my office nice and warm.

### ⭐ Cannot control heat cycle!
*by P***N on March 22, 2026*

First Blueair is a very good filtering device companies. I own four of better hepa filter units and I am completely satisfied and give them high marks. They might not should be in the heater business with the 3 in 1 cool, filter and heat introduced last year. The units would wither not cut off and heat as high as 7 degrees warmer then the selection or they just would stop heating all together. The 3 in 1’s I owned, do not maintain temperature in a 12x12 room well. It will heat 5-7 degrees higher than the device setting. Also the device setting for temperature skips around not allowing best temperature setting of choice. My $99 heater by a brand manufacturer maintains temp 1-2 degrees of the selection to the actual room temperature. This unit costs over $400, and there is a systemic issue with the heat cycle. I returned this twice and had same issues with all three unit’s. Blueair stood by the 1 year warranty but couldn’t ship me a device that worked as expected. The comment from their support was: The temperature skipping and heating behavior you described align with how the heating mode is designed to function. When setting the target temperature, the display may skip certain numbers — this is normal behavior. The heater will continue running until the room reaches the selected temperature, and then it will automatically turn off. If the room temperature drops below the set level, the unit will resume heating to maintain the desired temperature. Well as you can see from the above photo and unit taken seconds apart, this was not the case. The unit exceeded the desired temperature setting.
