FAQ

Our HEPASilent™ dual filtration technology removes 99.97%¹ of airborne particles down to 0.1 microns, ensuring pollen, cooking odors, smoke, dust, pet dander, mold, chemicals, allergen matter and even tiny particles such as viruses and bacteria², are captured with minimal noise and energy consumption.

To achieve maximum performance we recommend placing your Blue Pure 511 Max in a room around 192 ft² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes.

Operates quieter than a whisper on low at 22 db and is no louder than 44 dB on high fan speed.

We recommend replacing the filter on your Blue Pure Mini Max every 6 months. When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you.

Register your product to extend the 1-year warranty to a 3-year warranty.
