BLUEAIR Air Purifiers for Large Rooms, Cleans 3,048 Sq. Ft. in One Hour

The Blue Pure 211i+ Max HEPASilent™ smart air purifier is designed to quickly and efficiently clean up to 1,524 square feet of space in just 30 minutes or 635 square feet in about 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, earning 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 its use of Blueair's proprietary RealTrack algorithm, which takes into account the fan speed, usage time, and pollution levels to accurately calculate how dirty the filter is based on actual usage. This allows you to know more precisely when to replace the filter, typically within 9 months.

To ensure optimal performance, Blueair offers a genuine Blue Pure F2MAX replacement filter, which can be purchased as the Blue Pure 211i Max air purifier replacement filter B08KPHRLXR. Blueair is the only brand that offers a line of air purifiers with a customizable, washable fabric pre-filter, allowing you to tailor the look to your personal style.

The Blue Pure Max air purifiers are inspired by the latest Scandinavian design trend, arriving with the Stockholm Fog pre-filter, while Limestone, Moss, and Sand pre-filters are sold separately, giving you the flexibility to choose a look that complements your space.

Compared to the Blue 411 Auto model, the Blue Pure 411a Max and 411i Max offer up to 83% faster cleaning and 50% less noise on the high fan speed setting, making them a more efficient and quieter choice.*

The Blue Pure 211i+ Max is Quiet Mark certified, operating at a noise level of 23-53 dB, and can clean up to 3,048 square feet of space in 60 minutes, 1,524 square feet in 30 minutes, or 635 square feet in about 12.5 minutes on the high setting.

The secret to the air purifier's impressive performance is its HEPASilent dual filtration technology, which delivers more clean air faster and uses less noise and energy than HEPA filtration alone. This technology removes at least 99.97% of tiny airborne particles, including viruses and smoke, down to 0.1 microns, while also capturing pet dander, pollen, mold allergen, and dust. The built-in carbon filter also helps to trap light household odors from smoking, pets, and cooking.*

The Blue Pure 211i+ Max smart air purifier offers a range of customizable features through the Blueair app, including scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and the RealTrack accurate 6–9 month filter tracking technology. Additionally, Alexa voice control is available for hands-free operation.
