The Blueair Replacement Particle + Carbon filter for Blue Pure 311 Auto was designed specifically for the Blueair Blue Pure 311 Auto Air Purifier. It removes 99.97% of pollen, mold, dust, dander, bacteria, and viruses from the air. An Activated Coconut Shell Carbon filtration layer absorbs light gasses, VOCs, chemicals, smoke odors, cooking odors, and pet odors.
The HEPASilent™ Filtration Technology uses both mechanical and electrostatic filtration to create a less dense filter with increased airflow. This increased airflow creates a quieter and more energy-efficient filtration process. Another eco-friendly bonus is that the 311 Auto Filter is 100% recyclable.
Replacement of the Blueair 311 Auto Replacement Filter is simple. Push down on the unit's top while rotating counterclockwise, remove pre-filter sleeve and filter shelf ring, and then carefully lift the used filter out and replace with the new filter. For optimal results and to maintain peak performance and airflow, we recommend replacing the filter every 6-months
