Pure Dyson humidifier, evaporator and filter should be replaced once every one or two years. If the filter element of the humidifier is not damaged, it will not affect the use, so it does not need to be replaced, but it needs to be cleaned after a period of use.
Dyson humidifier has no filter element, which saves the trouble of frequent replacement. Before releasing water mist, Dyson humidifier will use patented ultraviolet sterilization technology to let every drop of water pass through ultraviolet rays, so that users can drink more safely.
