Blueair Blue Pure 311 Auto Air Purifier

Keep your air fresh and pure with the simple touch of a button thanks to the intelligent Blueair Blue Pure 311 Auto Air Purifier. Quiet and efficient, the 311 Auto is ideal for bedrooms and medium-sized spaces up to 388 square feet. Intuitive Air Quality Sensors are built right into the purifier to monitor current air quality conditions. Moreover, advanced Auto-Mode uses these sensors to automatically adjust your settings as needed. The 311 also boasts Blueair's proprietary HEPASilent™ Particle + Carbon Filter to remove allergens, bacteria, viruses, odors, gasses, and VOCs.

The Blueair 311 Auto stands apart from other purifiers thanks to its Smart Auto-Mode function and built-in air quality sensors. Most importantly, these two intelligent features work together to create a more efficient purification experience. First, (AQI) sensors detect harmful incoming PM 2.5 (particulate matter), including VOCs. Secondly, during auto-mode, the unit automatically adjusts settings to more effectively filter and eliminate these unwanted particles. And thirdly, the 311 Auto displays your current air quality conditions using an led color changing bar on the unit's front. The color blue indicates good air quality, orange represents moderate, and red means poor air quality. Once air quality returns to normal levels, your selected settings will resume. This technology helps streamline performance and stays on top of your indoor air quality for you.

Blueair's Proprietary Filtration System:

Blueair's Electrostatic and Mechanical Filtration is equipped with ionizers to negatively charge small incoming particles. These negatively charged particles are then physically attracted into the positively charged HEPASilent™ Particle + Carbon Filter. Uniquely, this allows the less dense filter material to trap more pollutants and particulates. Furthermore, the combination creates stronger airflow rates resulting in higher efficiency and reduced noise.

Pre-Filter Sleeve: Stylish and functional, the Pre-Filter Sleeve traps the larger particles first, helping extend the life of the HEPASilent™ Filter. It is available in five beautiful and optional shades - Archipelago Sand, Arctic Trail (included), Aurora Light, Winter Reed, and Night Waves. Not only does it allow you to customize your 311 Auto, but it is also machine washable and reusable, helping to save on future costs.

HEPASilent™ Particle & Carbon Filter: This exclusive filter by Blueair removes 99.97% of airborne particles down to 2.5 microns. These particles include dust, dander, mold, pollen, bacteria, and viruses. Additionally, the carbon layer helps absorb fine smoke particles, smoke odors, cooking odors, light gasses, and VOCs. Blueair's positively charged Particle + Carbon Filter is made from non-woven polypropylene fibers and coconut shell derived activated carbon. Moreover, this premium blend is free from chemical binders. Your HEPASilent™ filter should be replaced every 6-months, or 4,380-hours depending on use, and is 100% recyclable.

Located at the top of the unit, the One-Touch-Button Auto Mode controls the five adjustable fan speeds. Additionally, it engages auto-mode and powers the unit on/off. The one-touch-button also alerts you when it's time for the filter to be changed by glowing red. In the event that there is no activity after 7 second, the one-touch-button dims to 0% brightness. This function is ideal for dark spaces such as bedrooms or nurseries.
