I always recommend using soft water. Even though you sometimes see the mushroom salt crystals growing no harm is done. The sodium crystals thus deposited are much less harmful than magnesium crystals. With soft water the pads stay softer and more efficient. Changing once a year, before the heating season when peak efficiency is needed, is adequate.

It turned out that the water system in customer's house used some kind of salt based filter. The white stuff building up on the Dampp Chaser pads is if a residue of the salt. (Sorry if my explanation is not very scientific.) It doesn't seem to interfere with the operation of the Dampp Chaser. If it bothers them they could switch to distilled water.

The system is perfectly maintained (water from a filtering system, the Dampp Chaser product has always been added, new piano, new building with floor heat.) Last week I 've checked the system and was amazed to see big white mushrooms growing above the humidifier pads! I asked the supplier what could be the problem and he said it's the first time he encountered this. Any ideas how to avoid this?
