Three layers of ultra-advanced filtration
An outer fabric washable pre-filter starts the process by removing larger particles. This also extends the life of the main filter.
The main particle filter removes everything from pollen, dust and pet dander to bacteria.
Then a layer of activated carbon goes to work, ridding households of light odors from pets, cooking and smoking.
Maximum filtration.
Minimum noise.
Only Blueair air purifiers use HEPASilent™ dual filtration technology, delivering maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration along with a unique filter designed to produce more² clean air, cleaning your air much faster and more quietly³ than traditional HEPA filtration alone.
