Classic 500/600 Series Particle Filter

Our unique HEPASilent™ filtration technology allows this filter to be less dense, meaning it requires less air pressure. With it installed, your air purifier will operate quieter while using less energy.

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.

This filter's unique structure is designed to filter high volumes of air while trapping even the smallest particles. It maintains maximum airflow because it's engineered to resist clogging.

Filter fibers work to resist bacteria and mold growth in your home, helping to ensure you're never putting bacteria and mold back into the air.

This filter is compatible with the following Classic family models: 501, 503, 505, 510, 550E, 555EB, 580i, 601, 603, 605, 650E and 680i.

No, Blueair filters are less dense than traditional HEPA filters, allowing our air purifiers to be quieter and more energy-efficient. Instead of HEPA filters, we use a combination of electrostatic and mechanical filtration that we call HEPASilent™ technology to achieve the same level of filtration efficiency - with less energy and noise.
