Blueair Blue Pure 211i Max vs Rabbit Air A3

The Blueair Blue Pure 211i Max is a better overall air purifier than the Rabbit Air A3. While the Blueair is a little noisier than the Rabbit Air at its minimum speed, there's little to tell them apart in terms of noise at their highest fan speed, where the Blueair outpaces the Rabbit Air by a significant margin in terms of air purification performance. It's worth noting, however, that the Blueair's ionization system can't be disabled; this system produces a negligible amount of ozone while running, which is certified to fall within safe limits, but this can still be a dealbreaker if you or a pet in your home is particularly sensitive to ozone.
