Blueair Blue Extension 3410 Particle Carbon Replacement Filter for the

Less dense filters make the difference
Our unique HEPASilent™ filtration technology allows our filters to be less dense. Less dense filters require less air pressure— resulting in quieter and more energy efficient air purifiers.

Remove allergens & germs
The particle filter layer helps to minimize the airborne particles that can trigger allergy symptoms, including pollen, dust, mold spores, pet dander, viruses, bacteria, and fine smoke particles.

Remove household odors
A layer of activated coconut carbon absorbs light gases, including volatile organic compounds (VOC), smog, chemicals, and annoying household odors from pets, smoke, and cooking.

6-month filter life
To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day.

Traps particles for good
The filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
