A: The 211+ is effective at removing pet hair, dander, and light odors
A: Hi Sally, Blueair filters are comprised mostly of polypropylene, which is a widely recyclable plastic.
A: Hi Barbara, the 211+ is 20 H x 13 W x 13 in D.
A: Hi there, Blueair's HEPASilent™ and HEPASilent Ultra technologies use a combination of mechanical and electrostatic filtration to capture and remove harmful particles from indoor air; our technology is designed to specifically and strategically electrostatically charge particles at a very low current. This makes the particles adhere to the polypropylene fibers in the filter more easily due to electrostatic forces, which allows the use of a less dense filter, so more air can be pushed through with less noise and less energy.
A: Hello, The Blueair Blue Pure 211+ Purifier has a built-in LED indicator. The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing every 6 months.
A: Hi Matt, we would not recommend using a smart switch as we recommended running your air purifier 24/7 or as much as possible to ensure great air quality. We always suggest turning off the unit completely before unplugging the power outlet. If the power is constantly being shut off while the Air Purifier unit is running it may cause damage to its circuits in the long term. Moreover, the unit needs to be manually turned back on once power has been restored.
A: Thank you for your interest. This unit comes with a washable cloth prefilter and a particle plus carbon filter that is not washable and we recommend replacing every 6 months.
A: With Blueair products, you can breathe easy, with no increased danger from ozone. That’s because for 20 years, Blueair has been putting our air purifiers through independent tests to ensure that they do not release ozone. In fact, tests have shown that our products can actually lower ozone concentrations, with the ozone concentration in our system’s output air lower than in the incoming air. The tests are carried out in accordance with the California Air Resource Board (CARB) certification program, the most stringent requirements in the world for air purifiers. Working with Intertek, a CARB accredited test lab, Blueair products undergo a comprehensive series of tests to measure ozone emissions. In these 8-hour-long tests, air purifiers are tested on high and low speed – with and without the filter installed. The Intertek facility features environmental chamber technology, the most trusted and proven scientific method available for testing to see if products produce ozone. None of the Blueair products tested and investigated produced detectable ozone levels. Not only were Blueair purifiers found to comply with the requirements of the UL Standard 867 Section 37.1.2 criteria for emitting a maximum ozone concentration of less than 0.050 ppm, but also no measurable ozone concentration was detected at all.
A: Thank you for your interest. This unit covers 540sq.ft.
A: Blueair products are ETL listed and safe for use.
