The Wi-Fi enabled Blueair Classic 605 air purifier brings clean, energizing air to spacious bedrooms, living rooms or any big room that's up to 775 ft2 (72 m2). So you and your family can enjoy air that is virtually free of asthma and allergy triggers and indoor air pollutants. We’re proud to say that the Classic 605 purifies air so effectively that the Swedish Asthma and Allergy Association* recommends it for people with asthma and allergies.

Despite its exceptionally high air flow, the Classic 605 minimizes drafts, thanks to the Blueair SurroundAir™ system. SurroundAir™ takes in polluted air from the bottom and sides and releases a gentle flow of clean air from the top and sides.

The Classic 605 delivers unmatched performance thanks to HEPASilent™ technology, which combines electrostatic and mechanical filtration technologies. This combination, pioneered by Blueair, delivers high Clean Air Delivery Rate (CADR) with whisper-silent operation and high energy efficiency.

A digital control panel with easy-to-read LED icons lets you check the status of your air purifier’s Wi-Fi connection, operating speed and filter at a glance. Touch controls make it easy to adjust settings. By downloading the Blueair Friend app and connecting it to the Classic 605 you can also control your air purifier from any smart device, whether at home, at work or at play.

When you add our Blueair Aware Air Quality Monitor and connect it to the Blueair Friend app, you can also confirm that the people you love are breathing air that’s virtually free of allergy or asthma triggers and airborne pollutants.
