Impressive power in smaller size

Up to 1.5 x more powerful than products of its size (1), thanks to its innovative double-fan design. With powerful filtration of 600 m3/h (CADR), it can easily handle large spaces of up to 156 m2 (2) and can clean a room of 20 m2 in less than 5 minutes (3).

4 layer HEPA filtration traps 99.97% of smallest particles

4 layer filtration made of a pre-filter, HEPA NanoProtect and double Active Carbon layer captures 99.97% of particles as small as 0.003 microns (4) – smaller than the smallest known virus!

Quiet, even at maximum power

Experience 35% less noise with SilentWings technology (5). Inspired by the silent flight of owls, our fan-blade design ensures purification as quiet as 15 dB(A). Even at maximum speed, it's quieter than normal conversation. (6)

Captures 99.99% of allergens from dust, pollen or pets

All-day protection for allergy sufferers. Removes 99.99% of dust mite, pollen, pet or mould spore allergens (7), known triggers of allergy or hay fever symptoms (8). ECARF-certified allergy-friendly.

Effectively reduces viruses like H1N1 (flu) from the air

Removes 99.9% of airborne viruses and bacteria. Independently tested to eliminate H1N1 influenza virus (9), Staphylococcus bacteria (10) and 99.99% of SARS-CoV-2, the cause of COVID-19 (11).

Traps smells and gas pollutants

The Active Carbon layer captures odours and removes >96% of gas pollutants that hurt indoor air (12): NO2 from industry and traffic pollution, and Toluene or VOCs from house paint, detergents and furniture. Safe and effective: no ions, chemicals or ozone emitted.

Lower energy consumption than a light bulb

Enjoy cleaner air while keeping your energy bill low. At maximum power, the air purifier uses only 54 W, less energy than a traditional light bulb.

Intelligently senses and adapts to your indoor air quality

AeraSense technology scans the air 1000 x a second to detect pollutants and gases. It reports the air quality in real time on the product display or in the app. In Auto mode, the device intelligently chooses the right speed to respond to each situation.

Control your purifier anywhere with the Philips Air+ app

Pair the air purifier with the Air+ app for indoor and outdoor air quality monitoring, remote control and voice commands via Google and Alexa. In the app, select Auto+ mode for AI technology that adapts to your routine while minimising noise and energy use.

Go to sleep and wake up with fresh, clean air

Smart scheduling to fit your routine. Choose Fresh Wake-up to slowly ramp up purification speed before your set wake-up time. At night, Fresh Bedtime cleans your room thoroughly before you come to bed and welcomes you with a cosy, warm night light.

Long-lasting filter for up to 1 year

Original filters ensure optimal performance for up to 1 year (13), reducing hassle and cost. The purifier calculates filter life and alerts you when a replacement is needed. The accessory package (FY4200) contains both filters for the device.
