FAQ

Germ growth may happen when temperature and humidity levels are high. The Germshield™ functionality is designed to prevent germ growth inside the air purifier when the air purifier is not in use.

Register your product to extend the 1-year warranty to a 2-year warranty.

Your filter will last up to 1 year thanks to the RFID chip that accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.

When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you. Alternatively, connect to the Blueair app to receive an alert and easily re-order at the touch of a button.

The Protect 7470i operates quieter than a whisper on low at 22 db and is no louder than 45 dB on high fan speed.

To achieve maximum performance we recommend placing your Protect 7470i in a room around 418 ft² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes. The Protect will clean a 570 ft² space in 30 minutes, and 1,700 ft² in 1 hour.

¹24/7 protection refers to the key function of GermShield™ technology, that is activated when the unit is in standby mode. Tested on Staphylococcus albus and MS2 bacteriophage (deactivation) and Ecoli (growth prevention). Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.


²Air Changes per Hour (ACH) calculation is a product of recommended room size and average ceiling height over Pcadr


³Deactivation of germs on natural flora (excluding viruses)


⁴Based on third-party testing of removal rate of fine particles according to GB/T18801-2015 standard and pollen removal rate according to AHAM AC/1-2019 standard.


5Based on tests in a HealthProtect 7400 model comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration, producing higher CADR (GB/T18801-2015), lower noise level (ISO3743), and lower energy consumption (ANSI/AHAM AC-1).


6HEPASilentULTRA™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration. Based on particle CADR tests (GB/T18801-2015) comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration.
