A: Hi, thank you for being a Blueair customer! The air purifier filter is located under the pre-filter fabric. Your air purifier's built-in LED warning system will glow red to notify you when you are due for a filter refresh and we also recommend replacing the filter every six months for optimal clean air. The Blue Pure 211+ Auto Particle and Carbon Filter item number is 689122016207.
A: All of our units sold in North America operate using a standard supply voltage of 110 V. Units manufactured for the North American market are not dual voltage. We do not recommend purchasing North American units with the intention of converting them for for use overseas, as this would also void the warranty.
A: Hi there, all of our purifiers utilize our HEPASilent technology!
A: The Blueair 211+Auto was recently tested to capture 99.9% of SARS-COV-2 viruses. The 211+ uses the same technology. *Performance may vary depending upon the room size and location of the device within the room, quantity of particulates in the air, and product use pattern (operational settings and use duration, etc). Not proven to prevent/reduce transmission of COVID-19.
A: Hi there, our 211+ Auto is recommended for a room up to 550 ft2 in size.
A: Hi there, we do not use MERV ratings for our purifiers as this rating scale is typically reserved for HVAC units. AHAM is the independent third-party that conducts performance testing on our units.
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: Hi there, Blueair purifiers do not release phthalates into the air. Our models with the highest removal of VOC and odors are the HealthProtect family (which feature a SmartFilter that has activated coconut carbon directly infused into the weaves), Classic 80i family (which come standard with DualProtection filters), Pro family (when upgraded with the Carbon + filter add-on or SmokeStop filters), and the Blue Pure 121 (when upgraded with the Extra Protection Particle + Carbon filter).
A: Hi there, our air purifiers are great for reducing dust accumulation in your home!
