AC1711/90
Purifies rooms up to 78 ㎡
300 ㎥/h clean air rate (CADR)
HEPA & Active carbon filter
Powerful airflow circulation effectively covers spaces up to 78 m and distributes ultra clean air in every corner of the room. This boosts clean air delivery to 300 m/hr CADR, purifying 20 m in only 10 min. (1)
A 3-layer filtration with NanoProtect HEPA, active carbon and pre-filter makes sure you are protected from bacteria, pollen, dust, PM2.5, pet danderand gases.The NanoProtect HEPA technology not only captures pollutants, but it uses an electrostatic charge to attract them, enabling it to purify the air faster than a HEPA H13 filter that is medically used.

The VitaShield technology captures aerosols and particles smaller than the smallest known Coronavirus (6). Virtually nothing escapes from VitaShield - It deactivates viruses and traps them inside. Tested independently by Airmid health-group to remove up to 99.9% of viruses and aerosols from the air (2). Also, tested for corona virus (7).
(1)From the air that passed through the filter, it is a theoretical time for one-time cleaning calculated by dividing the room size of 48m³ by CADR 300m³/h (assuming the room is 20m² in floor area and 2,4 m in height).
(2)Tested by Airmid Healthgroup Ltd. in a 28.5m³ chamber with airborne influenza A(H1N1); reduction measured in Turbo mode after 10–20 mins. Air purifiers don't protect against COVID-19 alone but can support overall protection (US EPA).
(3)From the air that passes through the filter. Tested with NaCl aerosol by iUTA according to DIN71460-1
(4)From the air that passes through the filter, tested with birch pollen dust on filter media according to SOP 350.003 of the Austrian OFI institute
(5)NanoProtect HEPA filter material offers lower airflow resistance than HEPA H13 filters, allowing Philips air purifiers with NanoProtect to deliver a higher Clean Air Delivery Rate (CADR) than similarly sized certified HEPA H13 filters. Test by Philips, March 2016.
(6)Tested with NaCl aerosol by iUTA per DIN71460-1, from the air that passes through the filter. Coronaviruses range approx. 0.08–0.22 microns in size (MacLachlan, Dubovi, Fenner's Veterinary Virology, 5th Ed., Academic Press, 2017, Ch. 24, pp. 435-461).
(7)Microbial Reduction Rate Test at external lab, in a test chamber contaminated with human coronavirus (HCoV-229E) aerosols, with Philips HEPA NanoProtect filter.
(8)Recommended lifetime is calculated based on the Philips users’ average usage time and the WHO urban outdoor pollution level data. Actual lifetime is impacted by usage environments and frequencies.
