Cleaning the humidifier is important to make sure you stay healthy, and it’s performing at its best. If you have filters, then remove them intermittently and give them a rinse. One of the easiest ways to clean a humidifier is to do so with vinegar as this is a natural disinfectant. You can even run it with vinegar for a deep clean. Along with this, you should use small brushes to clear any grime. To reduce the need for cleaning, try and use distilled (or at least filtered) water as this will prevent build-up. Also, change the water more often if it’s just sitting in the tank. Most of these humidifiers are easy to clean, with some of them even having dishwasher-safe parts.
