what is a comfortable humidity level

A comfortable indoor humidity level is usually around 40% to 50% relative humidity. For many homes, a broader 30% to 50% range still feels comfortable, while staying below 60% helps reduce mold and moisture issues.

Quick Scoop

• Best general target: 40% to 50% RH.

• Winter: often 35% to 45% RH to limit condensation on windows.

• Summer: often 40% to 50% RH for comfort.

• Too low: air can feel dry and irritating.

• Too high: can encourage mold and dust mites.

Simple rule

If you want one easy number to remember, aim for about 45% humidity most of the time. If your windows fog up or the air feels muggy, the humidity is probably too high; if your skin, nose, or throat feel dry, it may be too low.

Practical tip

A cheap hygrometer can tell you your current indoor humidity, so you can adjust with a humidifier or dehumidifier as needed.
