BLUEAIR Blue Pure 311 Auto Replacement Filter

The Genuine Blue Pure 311 Auto Particle and Activated Carbon Replacement Filter is designed to protect against both gaseous and particulate contaminants. The filter's activated carbon mesh layer effectively eliminates harmful gaseous pollutants, such as volatile organic compounds (VOCs), tobacco smoke, and other odors. The advanced polypropylene filter media, on the other hand, removes particle pollutants as small as 0.1 microns, including pollen, dust, and pet dander, from your indoor air.

Featuring a 360-degree air intake and up to 4 times the filter surface area of competing replacement filters, the Blue Pure 311 Auto Particle and Activated Carbon Filter lasts longer, on average from 6 months to a year. To ensure a seamless replacement process, you can subscribe and save up to 10% on auto-delivered filters when needed. Blueair recommends replacing the filter about every 6 months, depending on usage.

Compared to the same models with only mechanical filtration, Blueair models with HEPASilent's mechanical and electrostatic filtration produced higher CADR, lower noise, and had lower energy consumption. The filter has also been independently tested and verified for its performance and safety, with a minimum reduction rate of 99.9% against E.coli, Influenza A (H1N1), and A.niger in 60 minutes. Additionally, the filter is AHAM Verifide for CADR, Ozone Safety Standards Certified by CARB, and Zero Ozone Verified (<5 ppb) by Intertek Sustainability Program.

In summary, the Genuine Blue Pure 311 Auto Particle and Activated Carbon Replacement Filter offers superior air purification capabilities, with a 360-degree air intake and up to 4 times the filter surface area of competing models. The filter effectively removes both gaseous and particulate contaminants, including the smallest airborne particles, while also trapping household odors, smoke, and VOCs. With its automated filter replacement option and independent testing for performance and safety, the Blue Pure 311 Auto Particle and Activated Carbon Filter provides a reliable and efficient air purification solution for your indoor environment.
