Replacement Air filter For Blueair Blue Pure 411 Air Purifier Filter

The Air filter Replacement  for Blueair Blue Pure 411 air purifier features a three-layer filtration system:

Pre-Filtration Layer: This layer of the cartridge uses a coarse fiber mesh to capture larger particles such as dust, pet hair and pollen. The pre-filtration layer serves to extend the life of subsequent cartridges and lighten their load.

HEPASilent Cartridge Layer: This layer of cartridges uses HEPASilent technology, which combines highly efficient mechanical filtration and electrostatic adsorption to capture more than 99.97% of particles above 0.1 micron, including bacteria, viruses, dust and pollen. It purifies the air while maintaining low noise and energy consumption.

Activated Carbon Cartridge Layer: This layer of the cartridge uses activated carbon material with strong adsorption capacity to effectively remove odors, fumes and volatile organic compounds (VOCs). The activated carbon cartridge provides fresh air, making indoor air healthier and more comfortable.

The life span of the cartridge depends on the usage environment and air quality. It is usually recommended to replace the cartridge every 3 to 6 months based on actual usage to ensure continuous and effective air purification. To replace the cartridge, simply open the top cover of the purifier, remove the old cartridge and place the new cartridge in the appropriate position.
