Key Takeaways from the Comparison

For a small room, the Blueair Blue Pure 211+ is a no-brainer. It cleans the air from large and small particles, and also catches odors. One of the best air purifiers for any room smaller than 200 square feet.

The Blueair Blue Pure Auto 211+ is the best when it comes to the price / performance ration. It easily catches allergens and odors in 500 sq. ft. areas, providing the necessary relief for you or your family members. Great for wildfires too.

The Blueair Classic 605 is an old, but really great air cleaner for large rooms and spaces. It comes with a built-in ionizer for improved particle filtration and the whole unit can be controlled via the app (Android/iOS) or voice (Alexa/Google Home).

Another air purifier designed for large rooms is called Blueair Pro L. It has one of the highest AHAM-verified CADR ratings, and its main goal is to keep the air free from allergens, dust or smoke of any kind. It uses 2 HEPA filters that remove particles as small as 0.3 micron at 99.97% efficiency.

The Dyson Pure Hot+Cool HP04 features WiFi and built-in heater to keep you warm at cold days. It doesn’t uses HEPA filtration, however it’s still quite good at removing airborne irritants. It’s also cheaper compared to the top-notch Pro L.

On the other hand, the Dyson Pure Cool TP04 comes with the in-built cooler, which generates airflow of 800 CFM. In hot summer days it will not just keep the room or office suitable for living or working respectively, but will also remove various smells from cooking food, bathroom, outdoor pollution, and so on.
