Blueair Blue Pure 411 Auto HEPASilent Air Purifier

A: Hi there! I'm sorry for the delay in getting back to you here. Absolutely. We have many customer who have birds and use our products.

A: Hi Yvonne! Thanks for reaching out! Yes, the 411 filter will trap dust, pollen, mold, pet dander and anything else down to .1microns. There's also a layer of activated carbon that soaks up smoke and odors.

A: Blueair purifiers utilizes HEPA(High Efficiency Particulate Air)Silent™ technology which captures at least 99.97% of airborne particles down to 0.1 microns in size, removes germs and delivers especially high performance and efficiency by combining electrostatic and mechanical filtration technologies. Each new machine comes with a new filter installed and ready to go!

A: The 411 and 311 models are slightly different in their actual size and the square footage of the space they cover. The 411's cover up to 190ft2 and the 311's covers up to 388ft2.

A: 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 Maria, the power cord for the 411 Auto is approximately 30 inches long. Our purifiers cannot be battery operated and do need to be plugged into a wall outlet to work.

A: Hi there! After 5 months of continual use, your filter light will turn yellow. This indicates that it will be time for your filter change in one month and it is time to order a new filter. After 6 months of continual use, your filter light will then turn from yellow to red, indicating it is officially time to change the filter. After replacing the filter, turn on the unit and press and hold the main button for 10-45 seconds until the light goes back to white. This will complete your filter timer reset.

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, Blueair has conducted ongoing independent testing to ensure our air purifiers do not release harmful levels of ozone. All Blueair air purifiers are tested in accordance with UL Standard 867, demonstrating ozone emission levels far below the mandated California Air Resource Board (CARB) ozone emissions limit of less than 50 parts per billion (ppb). All Blueair air purifiers are CARB certified.
