Meet the new Blue Max series with our unique HEPASilent performance, now even better; up to 83% faster cleaning¹ and 50% less noise². Breathe clean air quickly and quietly with Blueair air purifiers. Only Blueair air purifiers use HEPASilent dual filtration technology delivering up to 45%³ more clean air faster and using less noise and energy than HEPA filtration alone⁴. Blue 3250i purifies up to 48m2 living space in 30 minutes or 20m2 in 12.5 minutes on high. When it comes to filtration, the combination of two technologies ensures the removal of at least 99.97%⁵ of airborne particles down to 0.1 microns. That means even the tiniest particles, such as viruses and bacteria, are captured, while larger particles such as dust, pollen and smoke are also removed. Blueair
