Product description

The Blue Pure 311 Auto air purifier takes a simple approach to smart air quality management with an integrated particle sensor, Auto mode setting, and LED air quality display. The air purifier delivers high performance with one-button control and customizable pre-filter colors in a lightweight, compact package. Independently evaluated and third-party tested for performance as part of the AHAM Verifide Program for room air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 250 for fine smoke particles, 250 for pollen particles, and 244 for dust particles. Recommended for medium rooms like a master bedroom, living room, or playroom with a 360° air intake to completely filter room air about every 12.5 minutes (4.8x an hour at 412 ft²) on the highest speed. The 3-step combination particle plus carbon filter works with Blueair’s HEPASilent filtration technology to remove 99.97percentage of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses and more, while an additional layer of activated coconut carbon traps light household odors. The one-touch enabled Auto mode is designed to help you maintain a comfortable and safe home environment. When enabled, the setting automatically adjusts to real-time conditions reported by the integrated particle sensor. Stay up to date on your air quality with the LED display, it changes color to indicate good, moderate, or poor.

Arctic sea ice has likely reached its minimum extent for the year, at 4.72 million square kilometers (1.82 million square miles) on September 16, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 minimum is the twelfth lowest in the nearly 43-year satellite record. The last 15 years are the lowest 15 sea ice extents in the satellite record. 

14 September 2021

Each September, the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder informs the public of the annual Arctic sea ice minimum extent, an indicator of how climate change is affecting the Arctic, the fastest-warming region of the globe.

Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona, and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation (NSF) to develop a virtual reality teaching tool called Polar Explorer.

The National Snow and Ice Data Center (NSIDC) announced this week their participation in the 50x30 Coalition, a group of governments and cryosphere and emissions research institutions endorsing the need to reduce greenhouse gas emissions 50 percent by 2030. The Coalition’s founding members endorse the scientific consensus that failure to reach this milestone will result in temperature “overshoot,” in which emissions remain too high to hold Earth within 1.5 degrees Celsius of pre-industrial levels, leading to major and irreversible damages to the environment. Damage may be especially harmful for highly temperature-sensitive frozen components of the Earth system, with impacts ranging from sea level rise to infrastructure damage to food insecurity.

Arctic sea ice has likely reached its maximum extent for the year, at 14.77 million square kilometers (5.70 million square miles) on March 21, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 maximum is tied with 2007 for seventh lowest in the 43-year satellite record.
