The air purifier ensures thorough cleaning in rooms up to 78 m² with a CADR of 300 m³/h. A 20 m² room is cleaned in less than 10 minutes. The 3-layer HEPA filter system (pre-filter, NanoProtect HEPA, activated carbon) removes 99.97 % of particles down to 0.003 micrometres, smaller than the smallest known virus. The automatic air humidification delivers up to 650 ml/h and adapts to the desired humidity level thanks to AeraSense technology.

With the hygienic NanoCloud technology, the air is humidified with up to 99.9 % less bacteria than with conventional devices. The purifier also removes 99.9 % of viruses (e.g. H1N1, SARS-CoV-2) and bacteria. It is whisper-quiet in idle mode (16.5 dB) and at 43 W consumes less energy than a light bulb.

AeraSense technology detects pollutants in real time and automatically optimises the settings. The Philips Air+ app can be used to control the appliance and monitor the air quality. The activated carbon layer filters over 90% of gaseous pollutants and odours, e.g. NO₂ and VOCs, without releasing harmful ions or ozone.

The 3.2-litre water tank allows up to 15 hours of humidification without refilling. The long-life filter lasts up to 1 year and the device automatically notifies you when it needs to be changed. Ideal for healthy, clean air and a pleasant indoor climate.

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.
