The Blueair Classic 405 series air purifier scrubs air of harmful particles in spaces large and small.  The Classic 405 purifies spaces up to 430 square feet and is small and stylish enough to fit into any room. With increased capacity and efficiency, the Classic 405 air purifier for asthma and allergies is a must have for premium indoor air quality.

Superior Performance, Superior Air Quality

What sets the Blueair Classic 405 apart is the sheer volume of air this unit can clean. The 405 will constantly be drawing in, cleaning and exhausting purified air in your home. Ideal for asthma and allergy sufferers, keep irritants out of the air for good with quick and thorough air purification.

In rooms up to 430 square feet the Classic 405 is rated to change the air five times an hour while delivering an impressive Clean Air Delivery Rate of 510m3 per hour when tested on dust and pollen.

Blueair uses their patented HEPASilent technology, a three-part process with incredible effective results. A small energy efficient motor draws dirty air into the unit. Particles in the air are then charged in an isolated charging chamber. Air is pushed through a polypropylene fiber HEPASilent filter. The charged particles are drawn to the filter fibers and binds with the filter media, trapping them for good. Blueair filters will trap particles as small as .1 microns 99.97% of the time. Finally, clean air is exhausted into your home.

With this special three stage process Blueair is able to operate quietly and use less energy than traditional air purifiers on the market.

Connected to Your Life

Blueair introduces comprehensive connectivity in the Classic 405. Connect your air purifier to a Blueair Aware module for real time environmental air quality feedback. When you download the Blueair Friend app for iOS or Android you can control power and fan speeds from anywhere in your home.

Energy Star certified, Blueair units use only between 15 to 90 watts of energy. HEPASilent filter media is recyclable.

 A sleek user interface and modern forms will make you want to showcase this small but powerful air purifier for asthma and allergies. A redesigned, clear, easy to read LED display sits atop the unit and will adjust fan speeds, control power and indicate filter life.
