Blueair Blue Max 3250A/I Filter

Blueair’s proprietary RealTrack algorithm accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels

Blueair's 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 more quietly while using less energy

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.

With the unique filter design at least 99.97%³ of airborne particles, even down to 0.1 microns, are removed, while using less energy and producing less noise.

• Compatible with Blue Max 3250i & Max 3250 auto
• Recommended filter change: 6 months (4,380 hours) when used 24 hours a day
