Blueair Air Purifiers for Medium Rooms, Bedroom, Kitchen

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.

One of the key features of this air purifier is the proprietary RealTrack algorithm, which uses fan speed, usage time, and pollution levels to calculate the exact filter dirtiness based on actual usage, and provides more accurate information on when to replace the filter within 9 months. Genuine Blueair Blue Pure F3MAX replacement filters (B08KPDS2CY) are designed for optimal performance.

The Blue Pure Max air purifiers are part of Blueair's top-performing line, featuring the HEPASilent dual filtration technology that delivers more clean air faster and uses less noise and energy than HEPA filtration alone. These air purifiers are certified by Quiet Mark, operating at 23-50 dB, and are Energy Star Most Efficient 2023, using less energy (32W on high) than an incandescent (60W) light bulb.

The Blue Pure Max air purifiers are designed to remove at least 99.97% of tiny airborne particles, including viruses and smoke down to 0.1 microns, as well as pet dander, pollen, mold allergens, and dust. The carbon filter also traps light household odors from smoking, pets, and cooking.

The Blue Pure 311i Max comes with intuitive controls, a 5-color AQI display, and a simple two-button design that makes it easy to control the fan speed (1-3), including night mode, auto, brightness, and child lock. The Blueair smart air purifier app also provides features such as scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack filter tracking technology.

This product is independently tested for performance and safety, and is certified by AHAM Verifide, Quiet Mark, and CARB for ozone safety. It is also verified to have zero ozone emissions (less than 5 ppb) by Intertek Sustainability.

The Blue Pure 311i Max air purifier is designed for North American use only and should only be used with input voltages between 110-120V. It comes with one filter pre-installed and a pre-filter for easy setup.
