Question about Philips PureProtect Water 3400 Series

Yes, the device can also be used without the humidification function, i.e. without water, just for air purification. Air purification takes place via a 3-layer HEPA filter system that removes pollutants such as fine dust, pollen, viruses and odours, regardless of the humidification function. The humidification function is optional and can remain switched off in summer if there is sufficient humidity.
