I get pretty good hite 'dust' from the softened well water with an Ultrasonic. Our softened well water is ~100ppm and our unsoftened is ~220. Not a huge drop but, but noticeable in things like our dishwasher. Probably amounts to our water softening system being about 20 years old. So, assuming that its a straight correlation, a filter would last me 3 months. The other option would be to cut it with distilled, which would be half as much distilled water vs. using distilled in a ultrasonic. Not that distilled is expensive but more of a pain to keep buying.Hard water greatly shortens the life of filters in evaporative humidifiers and my water is around 650 ppm..... trashed a filter in a month. Last winter I started using the condensate from my furnace in all my humidifiers. The second filter i bought is still good to go.
Btw, my furnace condensate is around 25 ppm and i run it through a 5 micron carbon filter.
