400 specifications

The Blueair 400 series air purifiers are designed to enhance indoor air quality by employing advanced technologies and innovative features. Built to tackle common household pollutants, the Blueair 400 series is ideal for medium to large rooms, providing efficient and effective air purification for spaces up to 1,000 square feet.

One of the standout features of the Blueair 400 series is its unique HEPASilent technology. This cutting-edge filtration system combines mechanical and electrostatic filtration to capture a remarkable 99.97% of airborne particles as small as 0.1 microns. This means it effectively removes allergens, dust, pet dander, smoke, and even some bacteria and viruses from the air. The electrostatic approach enhances the efficiency of traditional HEPA filters, allowing for quieter operation and reduced energy consumption.

In addition to HEPASilent technology, the Blueair 400 series offers a three-part filtration system that includes an activated carbon filter. This component actively absorbs odors, gases, and volatile organic compounds (VOCs), ensuring the air in your home not only feels clean but also smells fresh. The combination of these filtration elements results in healthier, cleaner air that can significantly improve the quality of life for allergy sufferers and sensitive individuals.

The design of the Blueair 400 is both functional and aesthetically pleasing. Its sleek, modern appearance fits well in any decor, while the compact structure allows it to blend seamlessly into various room styles. The unit is also equipped with Smart Sensor technology, which automatically adjusts the fan speed based on the air quality detected in the environment. This smart functionality not only optimizes air purification but also operates silently when air quality is good, enhancing user comfort.

Furthermore, the Blueair 400 series operates at various fan speeds, with a quiet mode for nighttime use that ensures minimal disturbance during sleep. The user-friendly interface allows easy control, while the filter replacement indicator takes the guesswork out of maintenance.

Overall, the Blueair 400 series air purifiers combine high performance, advanced filtration technologies, and user-friendly features, making them an excellent investment for anyone looking to improve indoor air quality. With its powerful performance and beautiful design, the Blueair 400 makes breathing easy in the comfort of your home.
