PHILIPS AC3821/20 Portable Room Air Purifier  (White)

The NanoCloud Technology provides an efficient performance up to 600 millilitres per hour by using a natural and hygienic evaporation process. Smaller molecules are less able to carry bacteria into the air after the water is evaporated. This results in preventing wet spots and white dust, and also 99% fewer bacteria being spread.

The Sleep Mode combined with the device's aerodynamic design provides a silent and efficient performance, so you can get the quiet and peace you need while sleeping.

The safety of those in your home is paramount. This air purifier, through Optimized Purification Function, effectively detects and reduces bacteria and viruses, such as H1N1 (influenza), which paves the way for a clean and healthy home.

Since it requires less than 1 kWh per day, this energy- and cost-efficient purifier helps you save power and money.

This air purifier features the AeraSense Technology which detects and displays the risk level of air allergens in your room on a scale from 1 to 12. This can effectively warn you of potential allergens which could risk the health of your loved ones.

Thanks to real-time PM2.5 feedback, the professional-grade sensor featured in this device makes use of the AeraSense technology and accurately detects and instantly responds to even the slightest change in the air.

This device allows you to choose from three modes: General, Allergen and Sleep. While the Allergen Mode is extra sensitive, the Sleep Mode can be used when you need the display lights to be dimmed and the fan to be run at its lowest speed. You can choose a particular mode which meets your specific needs at that moment.
