Philips PureProtect Water 3400 Series Smart 2-in-1 Air Purifier and Humidifier

3-Layer HEPA Filtration

✔NanoProtect HEPA Filtration

3-layer filtration made of pre-filter, HEPA NanoProtect, and Active Carbon captures 99.97% of particles as small as 0.003 microns — smaller than the smallest known virus!

NanoProtect HEPA technology not only traps pollutants but uses an electrostatic charge to attract them, delivering higher energy efficiency than traditional HEPA H13 filtration.

✔Removes 99.9% of viruses from the air

Independently tested to eliminate H1N1 influenza virus, Staphylococcus bacteria, and 99.97% of SARS-CoV-2.

The Active Carbon layer captures odours and removes >90% of gas pollutants including NO2 from traffic, Toluene and VOCs from paints, detergents and furniture. Safe and effective — no ions, chemicals or ozone emitted.

Hygienic Humidification

✔NanoCloud Technology

No technology releases cleaner water vapour than NanoCloud. Its ultra-fine mist is invisible to the naked eye and extremely difficult for bacteria or residue to adhere to. Humidify air with up to 99.9% fewer bacteria released than standard ultrasonic humidifiers — safe to use with tap water.

✔3.2L water tank for continuous use

Combat dry air symptoms such as dry skin, chapped lips, and irritated nose or throat with rapid humidification up to 650 ml/h. Thanks to its large 3.2L water tank, you can enjoy up to 15 hours of uninterrupted humidification without needing to refill.

Automatically Senses and Adapts

✔AeraSense Sensors & Display

AeraSense technology scans the air 1000x a second to detect harmful pollutants, intelligently selecting the best setting. It displays real-time air quality (PM2.5) as well as the current humidity level — on the device or in the app.

✔Go to sleep and wake up with fresh, clean air

Use smart scheduling to fit your routine. The built-in ambient night light creates a clean and comforting sleep environment for the bedroom or nursery. In Sleep mode, the display dims and the fan operates near-silently so the whole family sleeps soundly.
