The Blue Pure 211i+ Max HEPASilent™ smart air purifier is designed to quickly and efficiently clean spaces up to 1,524 square feet within 30 minutes or 635 square feet in approximately 12.5 minutes on the high setting. This air purifier has been independently evaluated and third-party tested to meet safety standards and performance criteria 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.

The device's performance is further enhanced by Blueair's proprietary RealTrack algorithm, which utilizes fan speed, usage time, and pollution levels to accurately calculate the filter's level of dirt and grime based on actual usage, providing you with a more precise indication of when to replace the filter, typically within 9 months.

For optimal performance, Blueair recommends using the genuine Blue Pure F2MAX replacement filter (model B08KPHRLXR). The Blue Pure line of air purifiers is the only one in the market with a customizable, washable fabric pre-filter, allowing you to personalize the look and feel of your device. Inspired by Scandinavian design trends, the Blue Pure Max air purifiers come standard with the Stockholm Fog pre-filter, while additional Limestone, Moss, and Sand pre-filters are sold separately.

Compared to the previous Blue 411 Auto model, the Blue Pure 411a Max and 411i Max models offer up to 83% faster cleaning and 50% less noise on the high fan speed setting. This improvement is achieved through Blueair's HEPASilent dual filtration technology, which delivers more clean air while using less noise and energy than traditional HEPA filtration alone.

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

In addition to its impressive performance, the Blue Pure 211i+ Max also excels in air purification effectiveness. It 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 allergens, and dust. The device's carbon filter also helps to trap light household odors from smoking, pets, and cooking.

The Blue Pure 211i+ Max air purifier offers smart features, including an accompanying app for scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack accurate 6-9 month filter tracking technology. Alexa voice control is also available for added convenience.
