Cleaning and Filling Your Humidifier's Water Chamber


If I lose the cap, will I need to replace my entire humidifier?

Definitely not; the cap will be a sufficient replacement.

Will this fit H3i humidifiers?

No, the design for the H3i and H4i humidifier is different. This is intended for the H4i only.
