  • (1)From the air that passes through the filter, it is a theoretical time for one-time cleaning calculated by dividing its Clean Air Delivery Rate (CADR) 610 m³/h by the room size of 48 m³ (assuming the room is 20 m² in floor area and 2.4 m in height).
  • (2)CADR is tested by a certified third-party lab, in accordance with GB/T18801-2015. Following improvements in our testing method and production quality control, we upgraded the CADR values of our products. If you buy a product where this information is not updated on the box yet, rest assured that the product performs at the higher specification mentioned online.
  • (3)Microbial Reduction Rate Test conducted at Airmid Healthgroup Ltd., tested in a 28.5 m³ test chamber contaminated with airborne influenza A(H1N1). An air purifier by itself does not protect against Covid-19, but can be part of the plan to protect yourself and your family (US Environmental Protection Agency)
  • (4)From the air that passes through the filter, tested with NaCl aerosol by iUTA according to DIN71460-1.
  • (5)Microbial Reduction Rate Test at external lab, in a test chamber contaminated with avian coronavirus (IBV) aerosols, with Philips HEPA NanoProtect filter.
  • (6)The recommended service life for the device is based on a theoretical calculation of the average annual regional values of harmful air particles outdoors and daily use of the air purifier for 16 hours in automatic mode.
  • (7)Tested on the filter media for 1 pass efficiency at 5.33 cm/s airflow, by a third-party lab./From the air that passes through the filter, tested to JISB 9908-2012
  • (8)Alexa and Google Home availability depends on your location
  • (9)The calculated average sound pressure at 1.5 metres from the device, based on measurements according to IEC 60704. Sound pressure level depends on the room construction, decoration and positioning of the device and listener.
  • (10) As tested in a real-life setup, with dust resuspended by a person stepping into bed.
  • (11) Based on CADR measurements according to GB/T-18801/2015 with device operating in Sleep mode and Allergy Sleep mode.
  • (12)Philips air purifiers have higher Clean Air Delivery Rate and energy efficiency with a NanoProtect HEPA filter than with a HEPA H13 filter, tested to GB/T 18801
  • (13)From the air that passes through the filter, tested with NaCl aerosol by a 3rd party laboratory
