Healthier air and 99% less bacteria NanoCloud technology allows you to moisturize the air using a natural steaming process. The invisible mist, which forms a microscopic size of water particles, provides 99% less bacteria compared to ultrasound humidifiers. The water particles are so small that bacteria are harder to attach to them. Without ions, ozone and harmful chemicals Evaporative air humidification with NanoCloud technology is a natural and safe method of moisturizing. Comfortable and healthy level of air hydration The recommended level of air hydration from 40% to 60% minimises the probability of health problems that may increase or be caused by dry air. This range of hydration also prevents the development of bacteria and moulds and makes air breathing more pleasant at home. Automatic constant hydration maintenance The intelligent sensor continuously monitors the humidity of the air and automatically maintains its constant humidification. Simply select the preferred level – 40%, 50% or 60% . You can also choose automatic mode, and the humidifier will adjust the appropriate hydration itself. With a colour indicator you can monitor whether the air in the house has already reached the humidity level set by us. Without white sediment and wet spots Water contains minerals, lime and magnesium, and when its drops settle on furniture, walls and floors, white sediment can be formed. Philips technology effectively prevents it. A very small, invisible fog is too small to carry minerals. Additionally, the mist particles are light and remain suspended in the air for longer and evenly moisturize the air without forming wet spots around the device. Water level control and work time programming The humidifier has an automatic humidity sensor that will shut down after running out of water in the tank and a clock for programming work for 1, 4 or 9 hours. Quiet and efficient work all night long In order not to disturb your sleep, the special night mode reduces the noise level of the device to a minimum. Additionally, it disables almost all light signals, leaving only the speed indicator.
