I use one by Taotronics I got on Amazon. It’s nice not too expensive, this is a similar one Humidifiers for Bedroom, 4L Cool Mist Humidifiers with Humidistat, PARIS RHÔNE Smart Vaporizer humidifier for Home Large Room, LED Display, Quiet Operation, Sleep Mode, 24H Timer, Night Light https://www.amazon.com/dp/B09NC2SVPC/ref=cm_sw_r_cp_api_i_MSXZ59RAF4E41Q72QCD9?_encoding=UTF8&psc=1
So I use this one from Amazon
I like it because it measures the AH. However it does deposit water which is the downside. I keep a mat underneath it and wipe up water with a towel if needed. I just use tap for it. No reason to use my distilled water for anything other than feeding. I have alocasias and other finicky plants that do great.
I have a supersonic that does not deposit water but isn't as strong or have a timer which I like about the first. The humidifier you have is really nice though! Im surprised it deposits residue.
I believe the water main flushing has something to do with it. Dunno. I do know that when they flushed the water a few years ago, it wiped out my fish tank. I'm 804. Our water probably isn't too far apart if I had to guess. This is the unit I've been using and it's been solid. Take care now.
This one works great for me, you can set humidity levels or put it on a timer. In my 120cm x 60cm tent it works for well over a day before I need to refill it.
