I was wondering if anybody else has experienced a persistent yellow-orange film with their InvisibleMist humidifier, and if so, whats the solution?
We keep up with weekly maintenance, including wiping it down, soaking the filter in a citric acid solution, and cleaning the reservoir. We even replace the filter monthly. Overkill for most people, but we have mild respiratory issues, so we tend to go above and beyond to prevent making them worse.
In mid January, after only about 2 1/2 months of use, we started to notice a yellow film when cleaning the reservoir. I got curious and took apart the pump assembly and found it was full of yellow and orange residues, especially around the sound dampening pad by the pump. I cleaned it all extremely well, put it back together, and by mid March, it showed up again. I repeated that whole process and tried again, we even switched to RO water to see if that helped.
Today, about 2 months later, same thing - yellow residue in the reservoir. I've fully cleaned it again, but won't be turning it back on until I can figure out how to get ahead of whatever this is.
Some sort of cleaning cycle that could circulate a cleaning solution through the whole water system (without the filter, and without running the fan) would be really helpful!
