The HU4811/10 humidifier from Philips distributes humidified air evenly throughout the room and spreads 99% less bacteria than ultrasonic devices. For a comfortable and healthy air humidification without haze formation in your home. This Philips humidifier offers a natural, advanced evaporation system with NanoCloud technology. For this purpose, dry air is drawn in, enriched with water molecules and released back into the room as humidified air. Due to their small size, the molecules are less able to carry bacteria into the air. Thanks to the 360° design, the air is distributed evenly throughout the room. Thus, this product prevents wet stains on floors or surfaces and reduces the risk of spreading minerals in the air, preventing white dust on furniture and surfaces. With NanoCloud technology, the water is not heated, so there is no risk of burns from hot water or warm steam. In sleep mode, the humidifier runs at a minimum noise level and all displays other than the speed indicator are off. This setting ensures that you can maintain your desired humidity level at all times, even when you are asleep. 2 fan speeds, which reach a humidification rate of 250 m/l at the highest level, are perfectly suited for rooms up to 38 m². If the tank is to be refilled, a red light indicator warns you, if the tank is completely empty, it switches off automatically. This reduces any security concerns. The Easy Clean design ensures easy cleaning. As there is no heating plate, no descaling is necessary. Only the filter has to be replaced every three months.
