BLUEAIR Air Purifiers for Medium Rooms, Homes, and Pets

The Blue Pure 311i Max HEPASilent™ smart air purifier is designed to quickly clean up to 929 square feet of living space in 30 minutes or a medium-sized room of 387 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, with a Clean Air Delivery Rate (CADR) of 250 for fine smoke particles, dust, and pollen.

The filter life is maximized thanks to Blueair's proprietary RealTrack algorithm, which uses fan speed, usage time, and pollution levels to accurately calculate the filter's dirt level based on actual usage, providing a more accurate indication of when to replace the filter within 9 months.

Blueair offers genuine Blue Pure F3MAX replacement filters (B08KPDS2CY) designed for optimal performance with the Blue Pure 311i Max air purifier. The Blueair line of air purifiers is unique in offering customizable, washable fabric pre-filters inspired by the latest Scandinavian design trends, such as the Stockholm Fog, Limestone, Moss, and Sand pre-filters.

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. Blueair's HEPASilent dual filtration technology delivers more clean air faster, using less noise and energy than HEPA filtration alone.*

The Blue Pure 311i Max air purifier is certified by Quiet Mark, operating at a noise level of 23-50 dB, and removing at least 99.97% of tiny airborne particles down to 0.1 microns, including viruses, smoke, pet dander, pollen, mold allergens, and dust. A carbon filter also traps light household odors from smoking, pets, and cooking.***

The Blueair smart air purifier app offers features like scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack filter tracking technology. Alexa voice control is also available.

The intuitive display, 5-color AQI, and simple two-button design make the Blue Pure 311i Max easy to control, with adjustable fan speeds, night mode, auto mode, brightness, and child lock.

Blueair air purifiers are independently tested for performance and safety, certified as Quiet Mark, CARB Ozone Safety Standards, and Intertek Sustainability's Zero Ozone Verified (<5 ppb). They are also Energy Star Most Efficient 2023, using less energy (32W on high) than an incandescent (60W) lightbulb.

The Blue Pure Max air purifier comes with one filter pre-installed and a pre-filter for easy setup. This product is made for North American use only and should only be used with input voltages between 110-120V.
