With normal use and regular cleaning, this chamber should last an average of 3 to 6 months.
Replace sooner if you notice mineral buildup that won't come off with cleaning, cracks, cloudiness, or discoloration. Hard water shortens the lifespan — distilled water extends it.
Cleaning your humidifier chamber
- Daily: Empty any unused water, rinse with fresh water, and let air dry.
- Weekly: Wash the chamber and lid with warm, soapy water. Rinse thoroughly and air dry.
- Use distilled water whenever possible — minimizes mineral buildup and significantly extends chamber life.
- Avoid harsh cleaners, bleach, or dishwashers — these can damage the chamber materials.
