The Blueair 500/600 Series Particle Filter delivers superior filtration performance with HEPASilent™ technology, combining electrostatic and mechanical filtration to capture 99.97% of airborne particles as small as 0.1 microns — even at the lowest fan speed.

This advanced filter traps dust, pollen, pet dander, mold spores, and smoke particles, while the gradient structure ensures maximum airflow and prevents clogging. Unlike traditional filters, it doesn’t re-release particles into the air — even when fully loaded.

Built with naturally antibacterial polypropylene fibers, it resists bacterial and mold growth, ensuring only clean air is recirculated. Its less dense structure means lower pressure drop, leading to greater energy efficiency. Fully recyclable, it's an eco-friendly choice for those who care about cleaner air and a healthier environment.
