Blueair Large Room Air Purifiers, 3,048 Sq.Ft. Cleaning, HEPASilent Smart Cleaner for Home, Pets, Allergies, Virus, Dust, Mold, Smoke - Blue Pure 211i Max

The Blue Pure 211i+ Max HEPASilent™ smart air purifier is designed to quickly clean up to 1,524 square feet of space in just 30 minutes, or 635 square feet in around 12.5 minutes on the high setting. This air purifier has been independently evaluated for safety standards and third-party tested for performance as part of the AHAM Verifide® Program for air cleaners. It boasts a Clean Air Delivery Rate (CADR) of 410 for fine smoke particles, dust, and pollen.

One of the standout features of this air purifier is the proprietary RealTrack algorithm, which uses fan speed, usage time, and pollution levels to accurately calculate the filter's dirt accumulation based on actual usage. This allows you to know more precisely when to replace the filter, which is typically within 9 months.

For optimal performance, it is recommended to use the genuine Blueair Blue Pure F2MAX replacement filter (model B08KPHRLXR). The Blueair line of air purifiers is unique in offering customizable, washable fabric pre-filters. The Blue Pure Max air purifiers come with the Stockholm Fog pre-filter, while Limestone, Moss, and Sand pre-filters are sold separately, allowing you to match your decor.

In terms of cleaning performance, the Blue Pure 411a Max and 411i Max models have a higher pollen CADR on the high fan speed compared to the Blue 411 Auto. However, other units may vary in their CADR ratings, as these are based on the AHAM maximum allowable certified rating, which can differ from the AHAM seal claimed value.

The Blue Pure Max air purifiers are Quiet Mark certified, operating at a noise level of 23-53 dB. They are capable of cleaning up to 3,048 square feet of space in 60 minutes, 1,524 square feet in 30 minutes, or 635 square feet in around 12.5 minutes on the high setting.

The HEPASilent dual filtration technology used in these air purifiers delivers more clean air faster, while using less noise and energy than HEPA filtration alone. This technology removes at least 99.97% of tiny airborne particles as small as 0.1 microns, including viruses and smoke, as well as capturing pet dander, pollen, mold allergens, and dust. The carbon filter also traps light household odors from smoking, pets, and cooking.

The Blueair smart air purifier app offers convenient features like scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and the RealTrack accurate filter tracking technology. Additionally, Alexa voice control is available for hands-free operation.

In summary, the Blue Pure 211i+ Max HEPASilent™ smart air purifier is a top-performing, feature-rich air purifier that delivers fast, quiet, and efficient air cleaning for spaces up to 1,524 square feet. Its advanced technology, customization options, and smart features make it a compelling choice for those seeking a high-performance air purifier.
