“Since we put this air purifier in our living space, we’re not spreading the sicknesses around,” a reviewer with two young kids said. “My husband and I have hardly gotten sick all school year!”

This air purifier has an auto-function that detects when the air has pollutants and speeds its fans up accordingly to capture the dust, odors, particles like viruses and smoke, mold and more. It also catches airborne dander, helping relieve allergies for those sensitive to pets. “My partner’s sniffles and red eyes from pet dander are a thing of the past,” one wrote. “Children have less sniffles and less coughing,” said another.

You can manually set its fan speed to clear your space faster or pair it with its smartphone app for scheduling, air qualify monitoring and filter replacement (also sold on Amazon) reminders. Blueair claims this model cleans 83% faster and makes 50% less noise than earlier models of its air purifiers.

It features a night mode to turn off its lights, just in case you’d like to put yours in the bedroom, plus it connects with your Wi-Fi so you can link it with Alexa for voice commands and schedules.

Several reviewers say it’s super quiet and its auto-fuction works really well. “One morning my wife was cooking bacon,” explains a reviewer,” and the auto kicked in and ramped up to high to clear the air. Tells me the sensors really work and doing their best to keep your air clean.”
