    Up to 99% less bacteria: ideal for baby & toddler rooms

    Up to 99% less bacteria: ideal for baby & toddler rooms

    There is no other technology that releases cleaner water vapor into the air than Philips NanoCloud. Its ultra-fine mist is extremely difficult for bacteria to adhere to. The advantage is air humidification with up to 99% less bacteria releases than standard ultrasonic humidifiers (4), making this humidifier an ideal solution for baby rooms.

    Leaves no white dust or wet spots on floors and furniture

    Leaves no white dust or wet spots on floors and furniture

    NanoCloud's invisible mist does not release white dust or leave wet patches (5). Large droplets emitted by ultrasonic humidifiers may dampen the surroundings and carry minerals that leave white residue on nearby surfaces. NanoCloud particles are too small to carry minerals, effectively preventing residue and stains.
