I copy & paste the following for you all to judge for yourself.
Will prolong use cause 'White Dust" to form on the nesting planks and damage it forever?

We need more data. FYI, Air-O-Swiss is a manufacturer of ultrasonic Humidifier. Looks like it needs
super clean water & a lot of maintenance. Use it at your own risk.
"The Air-O-Swiss Room Humidifier System works by Ultrasonic Humidification. Water from the Removable Water Reservoir first travels through a Dimineralization Cartridge. The granules within the cartridge remove minerals from the water that can produce "white dust" in the room and also prevents lime scale build-up within the humidifier, making cleaning a simple task. White dust is caused when minerals are carried into the room air from a humidifier and precipitates out when the water vapor evaporates. After leaving the Dimineralization Cartridge, the water travels to the base of the unit where it contacts the patented Ionic Silver Stick®. The Ionic Silver Stick® releases silver ions to kill bacteria and viruses within the water and maintain constant water purity. If the pre-heating option was selected, the water will be heated to 176°F. The water within the base then travels to the Nebulizer Chamber and contacts the Ultrasonic Vibrator, which creates high frequency oscillations to transform the water in the base into a micro-fine mist. The Ultra-Quiet Fan pushes air into the Nebulizer Chamber where the air and micro-fine mist mix together. The air continues up the Evaporation Chamber and is released into the room where the water vapor fully evaporates immediately to release moisture and increase the relative humidity of the room
Maintenance
Water conditions will dictate the amount of maintenance and cleaning required. Using hard water with a lot of minerals will require more frequent demineralization cartridge changes and unit cleaning. The design and features of the Air-O-Swiss Humidifier provides a system that requires much less maintenance and has lower operating costs when compared to other humidifier systems.
Maintenance Procedures
*
Every two weeks check the unit base for any deposits. Clean any deposits around the titanium disc with the provided brush. Use a mixture of white vinegar and warm water in a 1:2 ratio to help remove deposits.
*
Replace the demineralization cartridge every 2-3 months, depending on water conditions. More frequent changes may be needed for hard water (high mineral content) conditions.
*
Replace the Ionic Silver Stick® once a year."
