Help/advise needed for ultrasonic humidifiers white dust problem
Hello people,
Indoor summer humidity in my city/apartment drops to 10% and my goal is to maintain at least 30–35%.
My first attempt was optimistic of buying desktop 3 liter humidifiers. Used to ran them 24x7 but humidity barely moved on my meter. Small tank required frequent filling and cleaning until I decided to go for larger humidifiers.
Second and current attempt was a replacement of small ones with three units of 25 liters each which helped me elevate indoor humidity to 25-27% level, still below my target but then I started to note some strange white-power all over the furniture, inside PC, on TV screens, even inside the glass bed of my scanner which is literally impossible to penetrate and impossible to clean unless I disassemble whole scanner to get under the glass.
A bit of Googling/Reddting reveal that tap water is the culprit (which is heavy) and many people suggested either going for "evaporative humidifiers" (something I didn't knew and it's too late anyways as I have invested $300 in 25L humidifiers). I noted some people suggesting the use of distilled water but it's not affordable in my case because I need 75 liters (25 x 3) water refill daily so my costs will just skyrocket.
I Googled and used GPTs to seek options and only cost effective outcome is under-sink RO system because according to these tools things like activated charcoal, descale resins, demineralization cartridges won't help, and so on. Now before I invest time, money and efforts in RO system, did anyone tried this solution or have some advise before I go for RO system?
Thanks.
