Blueair Air Purifiers for Medium Rooms, Bedroom, Kitchen - Blue Pure 311i Max

The Blue Pure 311i Max HEPASilent™ smart air purifier is a powerful and efficient solution for quickly cleaning up to 929 square feet of living space in 30 minutes or a 387 square foot medium room 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, achieving 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 accurately calculate the filter's level of dirtiness based on actual usage, and provides more accurate guidance on when to replace the filter within 9 months.

The Blueair Blue Pure F3MAX replacement filters (model B08KPDS2CY) are designed for optimal performance with the Blue Pure 311i Max air purifier. Blueair is the only line of air purifiers that offers customizable, washable fabric pre-filters, with the Stockholm Fog pre-filter included and Limestone, Moss, and Sand pre-filters available separately.

Compared to the Blue 411 Auto model, the Blue Pure 411a Max and 411i Max have a higher pollen CADR on the high fan speed setting. However, it's important to note that the AHAM maximum allowable certified rating may vary from the AHAM seal claimed value.

The Blue Pure Max air purifiers are designed to be quieter and more energy-efficient than HEPA filtration alone. The Quiet Mark certification and tested noise levels ranging from 23 to 50 dB make these purifiers well-suited for use in living spaces. The HEPASilent dual filtration technology delivers more clean air faster while using less noise and energy.

These air purifiers are highly effective, removing at least 99.97% of tiny airborne particles down to 0.1 microns, including viruses and smoke, as well as capturing pet dander, pollen, mold allergens, and dust. The carbon filter also helps trap light household odors from smoking, pets, and cooking.

The Blueair smart air purifier app offers a range of customizable features, including scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack accurate 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's air purifiers are independently tested and certified for performance and safety, with AHAM Verifide certification, Quiet Mark certification, and ozone safety standards certification by CARB. They also have zero ozone verification (<5 ppb) by Intertek Sustainability.

These air purifiers are Energy Star Most Efficient 2023 certified, using less energy (32W on high) than a standard incandescent (60W) lightbulb, making them an environmentally-friendly choice.

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