Best Dehumidifier for Basement: Say Goodbye to Musty Odor

A normal American home would have a trusty basement where the whole family could store everything that they are not currently using but might still need in the future. It has all sort of things like furniture, old curtains and clothing, photo albums, and other memorabilia.

This stuff gathers molds and mildew, dust, and other organisms that create that musty smell in the basement. This is why people are now on the lookout for the best dehumidifier for their basement to improve the atmosphere.

A contributing factor to the musty smell and growth of harmful organisms in the basement is its location. Understandably, they are under the house where most of the water fixtures are located.

They also easily get wet during typhoon or even with light rains. Because of the moisture present in this area in the house, it becomes a breeding ground for fungi, molds, mildew, and bacteria.

A basement would normally have a relative humidity (RH) higher than the tolerable range, which is 60% RH. Having an RH above this normal range is harmful to people, especially to children and the elderly who have weak immunity. An unhealthy RH brings sickness to the family such as allergies, asthma, and skin diseases.

Although it can be argued that the family does not often go in the basement, the air inside it still affects the overall air and humidity in the home. In addition, anything that is stored in your basement will be affected by the humidity conditions in there. With the use of the best dehumidifier for your basement, the smell can be made manageable, the health of your family will be protected and your possessions will stay in better condition.
