3 Things to Look For When Comparing Dehumidifiers


post img Can you maintain proper indoor humidity levels without the use of a dehumidifier? The Environmental Protection Agency recommends keeping household humidity levels below 60% for a healthy, comfortable indoor environment. It’s often a challenge to stay in that recommended range, however, particularly in climates like ours here in southern Ohio, where outdoor humidity often exceeds that limit. In these cases, you’ll probably want to consider a home dehumidifier. Here are three things to think about when comparing dehumidifiers to keep your home humidity in the optimal range:

Sizing

Individual room dehumidifiers are sized according to the amount of water vapor, expressed in pints, that the unit extracts from the air in a 24-hour period. For typical households with humidity in the range of 60% to 70%, a 30-pint unit is sufficient for a 300 square foot room while large spaces of 1,000-square feet need a 60-pint unit. In very damp houses with 80% humidity, the above size figures increase to 40 pints and 70 pints, respectively.

Tank Capacity

To reduce the number of times you’ll have to empty the dehumidifier’s water tank daily, the general rule is: the bigger, the better. For example, a 30-pint unit with a 10-pint water tank will require emptying three times a day. However, a 60-pint unit with a 15-pint tank will need to be emptied four times per 24 hours.

Whole-House Vs. Room Unit

Portable room dehumidifiers reduce humidity in a limited space only, plus require manual emptying of the tank. A whole-house dehumidifier, on the other hand, removes humidity from the entire air volume of your home as it passes through your heating and cooling ductwork. The unit condenses water vapor out of the air and conveys it down a drain line connected to your household plumbing. The humidistat that controls operation can be set like a thermostat, then automatically maintains the desired indoor humidity according to your setting.
