Fast purification suitable for spaces of up to 158 m2
360 degree airflow circulation effectively covers spaces up to 158 m2 and distributes clean air in every corner of the room. This boosts clean air delivery to 610 m3/hr CADR. It cleans 20m2 in only 5min (3).
Independently tested to effectively remove aerosols
One form of virus transmission is through suspended aerosols. An independent German study showed that Philips air purifiers cleaned 90% of aerosols in a 30m2 classroom of 27 students in just 30 minutes (4).
Filters 99.97% particles as small as 0.003 microns
3-layer filtration with NanoProtect HEPA, active carbon filter and pre-filter captures 99.97% of ultra-fine particles as small as 0.003 microns (5). This means you are safe from PM2.5, bacteria, pollen, dust or pet dander. Certified by the European Centre for Allergy Research Foundation.
Smart sensors for intelligent purification
Scans the air 1000x a second to detect ultra fine-particles and gas. Reports the air quality in real time, and intelligently chooses the right speed for your home (in auto mode).
Thoroughly tested for quality you can trust
Philips purifiers go through 170 mandatory and strict inspection tests before releasing from factory. They are subjected to rigorous life and durability tests, for continuous operation 24/7.
Ultra-quiet operation for minimum disturbance
In Sleep mode, display lights are dimmed, and the purifier operates in near silence.
Low energy consumption
Thanks to its energy efficient design, the air purifier runs at max. 60 W power. This is equivalent to one standard light bulb.
Air quality display
