See your air quality

Blueair Classic 690i equipped with improved laser sensor technology provides more accurate and reliable readings. At a glance, you can see the air quality in your room. Connect it to the Blueair app to track changes in – and get tips to improve – your indoor air quality, learn how air quality varies depending on your various activities, control your air purifier from afar using any smart device, and access outdoor air quality data.

Better air quality control
Your new Blueair Classic 690i is your air quality watchdog. An updated digital control panel and convenient LED touch buttons help you keep track of your air purifier’s operation, Wi-Fi connection and filter status as well as room air quality with indications of PM2.5 and VOC levels. Download the free Blueair app and connect it to the new Blueair Classic to control functions such as operating speed, child lock, night mode and more from afar using any smart device.

Blueair HEPASilent technology

Blueair HEPASilent Technology captures 99.97% of all airborne particles down to 0.1 micron in size. Its revolutionary combination of advanced filter media and an encapsulated particle-charging chamber ensures that your Blueair air purifier delivers results far superior than either mechanical or electrostatic technology alone.

Care for your loved ones
Many of us spend up to 90% of our time indoors, and indoor air is up to five times more polluted than outdoor air. With your Classic, you will get rid of 99.97% of all pollutants. When it comes to children, they are more sensitive to air pollution as their lungs, brains and immune system are still developing. They also breathe faster than adults, which means they take in more air relative to their body weight. Recent research shows that children's lungs and brains develop better when they breathe clean air. 
Timeless quality, solid performance
Available in wide range of models for every need, the next generation of our popular Classic dramatically reduces airborne particles at a significantly lower noise, using less energy. It minimizes triggers if you or your loved ones suffer from allergies, asthma and other respiratory illnesses. And thanks to the Wi-Fi connection, you will be able to switch on your Classic remotely to make sure you, your family and friends always breathe air that is 99.97% free of pollutants. With a Classic in your home, you and your family will feel healthier, happier and more energized.
