Miro recommends washing all parts once every five days. The frequency of cleaning will depend on the type and quality of water the user is using. Miro recommends using purified water.
When water stagnates, bacteria and mold will grow. We recommend treating Miro humidifiers like your dirty dishes! Just as you would wash these dishes daily, you should wash your humidifier every day.
Remember that this water is going into the air you breathe!
