Ideal humidity levels

The amount of humidity in the air varies depending on the season, the weather and where your home is. Humidity levels tend to be 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 issues.

• 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 water vapor in the air to turn into liquid. This is called condensation. Droplets may form on walls, floors and other surfaces. Condensation can cause the growth of harmful bacteria, dust mites and molds. These allergens can cause breathing problems and trigger allergy and asthma flare-ups.
