Ideal humidity levels

Humidity varies depending on the season, the weather and where your home is. In general, humidity levels are higher in the summer and lower in the winter. It's ideal to keep the humidity in your home between 30% and 50%. Humidity that's too low or too high can cause problems.

• Low humidity can cause dry skin. It also can bother the inside of the nose and the throat. It can make the eyes feel itchy too.
• High humidity can make your home feel stuffy. It also can cause condensation, which is when water vapor in the air turns liquid. Droplets may form on walls, floors and other surfaces. Condensation can trigger the growth of harmful bacteria, dust mites and molds. These allergens can cause breathing problems and trigger allergy and asthma flare-ups.
