Since warm air holds more water than cold air, the humidity rises in the cooling air and water condense on plants and other surfaces when the dew point is reached. When cold air is warmed, the moisture drops because there is relatively less water vapor.

Humidifiers help to bring needed moisture to the air during cold weather. But during the warmer months or when there’s is high humidity level; dehumidifiers can help take out the excess moisture in the air, making the indoor air feel cooler and dry.


Since indoor and outdoor temperatures changes constantly, the best way to determine humidity is with a device known as a hygrometer. It also acts as humidity sensors or relative humidity indicators; thus the instrument gives an accurate measure of the evaporation or condensation levels of your home or office.

There are quite a few variations of hygrometers available in various price ranges. The cheaper models are mechanical but may respond less quickly than digital a type (rechargeable operated models).

  • The rot of wooden window frames because of increased condensation of our windows.
  • Mold growth on our floors and ceilings.
  • Peeling of wall paint.
