Look, we all cut corners. I once used tap water in my humidifier for a week because I was too tired to go to the store. My coffee table ended up looking like it had been dusted with baby powder.
But your nose is smarter than you think. If you start smelling a slight earthy smell or feeling a tickle in your throat after using the humidifier, it’s telling you: stop using tap water.
Treating your humidifier right is like treating your pet goldfish right. A little care goes a long way. Use filtered or distilled water, clean it once in a while, and you’ll get years of sweet, misty relief. Your sinuses will actually sing.
