Recommended RH Range
45–55% RH
Balanced comfort and moisture control for most homes.
Suggested Setpoint
50% RH
Use a small buffer: set 50% to stay under 60% during humidity spikes.
How This Recommendation Works
- This tool provides guidance, not a guarantee. Real RH control depends on temperature, infiltration, wet surfaces, and dehumidifier capacity.
- As a practical rule of thumb, staying below 60% RH reduces mold risk in typical indoor environments.
- Cold basements and condensation-prone rooms often need a lower RH ceiling to prevent water on windows and walls.
- For sensitive items (books, instruments), stable humidity matters more than chasing very low RH.
Next Steps
- Estimate the electricity cost of running your dehumidifier under your local rate.
- Check dew point and condensation risk if you see water on windows or cold walls.
- Review maintenance basics to keep performance and efficiency stable.
