Philips

The air purifier impresses with its impressive performance and compact size thanks to the innovative double fan design. With a filter performance of 600 m³/h (CADR), it cleans rooms up to 156 m³ and can clean a 20 m² room in less than 5 minutes. The 4-layer HEPA filter system with pre-filter, NanoProtect HEPA and double activated carbon layer captures 99.97% of particles down to 0.003 micrometres - smaller than the smallest known virus.

SilentWings technology reduces the noise level by 35 % so that the air purifier remains whisper-quiet at just 15 dB(A) even at maximum power. It removes 99.99 % of allergens from dust, pollen, pets and mould, making it ideal for allergy sufferers (ECARF-certified). It also reduces 99.9 % of airborne viruses, including H1N1, Staphylococcus bacteria and SARS-CoV-2.

The activated carbon layer filters over 96% of gaseous pollutants such as NO₂, toluene and VOCs without releasing ions, chemicals or ozone. With an energy consumption of just 54 W, the air purifier is particularly energy-efficient.

The AeraSense technology monitors the air quality 1,000 times per second and automatically adjusts the cleaning performance. The device can be controlled from anywhere via the Philips Air+ app, including AI-based Auto+ mode to optimise energy consumption and noise levels.

The Fresh Bedtime mode with gentle night light ensures a restful sleep, while Fresh Wake-up cleans the air before you wake up. The long-life filter lasts up to 1 year and the accessory pack (FY4200) includes both filters. Sustainably designed, the device is made from over 30% recycled plastic and fulfils stringent durability tests for continuous operation.

Key specifications

Exact colour description

Room area

The room area is an approximate figure and is influenced by numerous factors. The indication of the room area refers to a typical flat with approx. 2.5 m room height.

CADR Value

CADR stands for "Clean Air Delivery Rate" and indicates the cleaning performance, i.e. how much room air is circulated and cleaned of different types of particles with a size between 0.09 µm and 11.0 µm within one hour. The value is given in cubic metres per hour (m3/h) and helps to compare the filter performance of air purifiers. Basically, the higher the value, the better, but the dimensioning of the air purifier should be adapted to the size of the room.
