Remember that RO water can make your humidifier smell weird if you don’t clean it. Seriously, it’s like the machine develops a personality and chooses “damp gym sock.”
I once left RO water in a humidifier for a week. The smell was so bad my cat left the room. That’s not a joke. She literally walked out, gave me a look, and didn’t come back for hours.
So, rule of thumb: RO water + clean humidifier = bliss. RO water + lazy you = biohazard chic. It’s your call.
But What About Cost?
RO systems are wallet-draining to install. But if you already have one for drinking water, using it in your humidifier is basically free. Your bank account will quietly thank you.
Compare that to buying gallons of distilled water from the store. One trip to the store for distilled water costs about $1.50 a gallon. Over a winter, that’s like buying a small island in jealousy.
So, yes, if you’ve got an RO system, go for it. Just know that you’re trading a little appliance risk for massive convenience and zero dust. That’s a trade I’m happy to make.
