Blue Pure 511 Air Purifier

Blueair's most compact air purifier, the Blue Pure 511, utilizes HEPASilent technology to quickly clean up to 432sqft of space in 30 minutes or a 180sqft small room in about 12.5 minutes. Its compact size and low noise levels make it perfect for placement in a bedroom or office. This air purifier is 24 dB quieter than a whisper on low and 49 dB on high, making it ideal for bedrooms, nurseries, or home offices.

The HEPASilent dual filtration technology removes at least 99.97% of airborne particles down to 0.1 microns, capturing tiny particles such as viruses and bacteria, as well as larger particles like dust, pollen, and smoke. The air purifier's design is customizable with three Scandinavian-inspired washable pre-filter colors, including an Arctic Trail dark gray pre-filter.

Certified by Energy Star as the Most Efficient model, Blueair air purifiers are whisper-silent and use less energy than a light bulb, while still providing fresh air with the touch of a button. The Blue Pure 511 Genuine Replacement Filter, designed for optimal performance, is also available.

The Blue Pure Max air purifier comes with one filter preinstalled and a pre-filter for easy setup, and is for use in North America with input voltages between 110-120V. The air purifier delivers 4.8 air changes per hour (ACH), ensuring efficient and compact air purification.
