Indoor humidity that is too high feels damp and encourages mould. If it is too low the air feels dry and uncomfortable.
The ideal range
Most experts recommend keeping relative humidity between forty and sixty percent. This range feels comfortable and helps protect your home.
How to measure humidity
A simple digital hygrometer shows the current humidity in each room. Many dehumidifiers also have a built in display.
Adjusting with a dehumidifier
Set the target humidity on your dehumidifier and let it cycle on and off. Aim for about fifty percent in living areas and bedrooms.
