Blueair Blue Pure 311 Auto Air Purifier

Enjoy cleaner air at the touch of a button. The intelligent and energy-efficient Blueair Blue Pure 311 Auto Air Purifier delivers exceptional performance in an attractive form. Designed for medium sized rooms, the Whisper-quiet 311 Auto is perfect for master bedrooms, living rooms, or playrooms. This smart purifier is packed with intelligent features. Our favorite is its Auto function, which monitors your room’s air quality and adjusts the fan speed accordingly. Additionally, Blueair's traditional HEPASilent™ Particle + Carbon Filter effectively traps pollen, dust, dander, bacteria, and viruses. Coupled with the activated carbon layer, it also removes odors, chemicals, gasses, and VOCs.

Blueair's One-Button Design controls it all. A single button lets you engage Auto-Mode, select between 3 adjustable fan speeds, and alerts you to change your filter. For convenience at night, the one-touch button illuminates while in use. However, after 7 seconds, the button dims down to 0% brightness. This makes the unit ideal for medium-sized bedrooms or nurseries up to 388 square feet in size.

The Blue Pure 311 Auto features Blueair's intelligent One-Touch Auto-Mode. This technology uses air quality sensors to detect incoming PM 2.5 (particulate matter). Once these harmful pollutants are detected, the setting automatically adjusts the fan speed to eliminate unwanted airborne contaminants more efficiently. Not only does the 311 Auto detect these harmful airborne particulates, but it alerts you to them as well. When your air quality is good, an illuminated indicator on the front of your 311 will turn blue. When the air quality is moderate, it turns to orange, and when the air quality becomes poor, the indicator changes to red. Because it can do all of this automatically, you no longer need to worry about adjusting the settings yourself. Simply engage auto-mode and let the 311 Auto do the work for you.

Blueair's Proprietary 3-Part Filtration System:

Also included with the Blue Pure 311 Auto is Blueair's advanced and ultra-efficient Electrostatic and Mechanical Filtration system. This groundbreaking filtration technology uses built-in ionizers to negatively charge incoming particulates. Once these particulates are negatively charged, they are then attracted to the positively charged HEPASilent™ Particle & Carbon filter. This enables the 311 to effectively filter out more particulates with a less dense filter. Consequently, using a less dense filter increases airflow rates and energy efficiency while decreasing noise levels.

• Pre-Filter Sleeve: The Blue Pure Auto comes with a stylish, functional, and machine washable pre-filter sleeve in the Arctic Trail color. This sleeve traps larger hair, dust, and dander particulates from your air before they reach the main filter. Moreover, It plays an integral part in the filtration process and helps prolong the main HEPASilent™ Particle & Carbon Filter. Pre-Filters also come in other optional interchangeable (not included) shades to match most decors. These shades include Arctic Trail (included), Archipelago Sand, Aurora Light, Winter Reed, and Night Wave.
• HEPASilent™ Particle & Carbon Filter: is made from non-woven polypropylene fibers and coconut shell derived activated carbon. This positively charged filter blend is free from chemical binders and helps filter 99.97% of airborne particulates down to 2.5 microns. Even more so, It effectively removes dust, dander, mold, pollen, bacteria, and viruses. Additionally, fine smoke particles, smoke odors, cooking odors, light gasses, and VOCs are absorbed by the carbon-based filter layer. Recommended filter replacement is every 6-months, or 4,380-hours, depending on use. This filter is conveniently 100% recyclable.
