Too much moisture in the air negatively impacts personal comfort, as humidity worsens health conditions like allergies and asthma. Plus, high humidity can damage household items, like electronics, pianos, cameras, books and clothing. Excess moisture causes mold, dripping pipes, peeling wallpaper, warping wood, blistering paint as well as musty odors. A dehumidifier is the remedy.
Even if you have home air conditioning, a dehumidifier may still be a necessity. In rooms such as basements and laundry rooms, where dampness is heavier due to natural conditions or where air conditioning may not reach, a dehumidifier will help, especially in reducing musty odors.
A dehumidifier helps maintain an ideal relative humidity level in the home (RH level). During summer months, a 50% RH is recommended. In winter months, as low as 30% RH is acceptable, especially if condensation is building up on your windows.
Consider these three main factors:
Dehumidifiers are rated by pint removal capacity every 24 hours. The following guide will help you choose the right capacity model for your needs.
In very damp or wet conditions, the unit will collect a large amount of water, and you'll need to empty the internal bucket regularly. Most units have a direct drain feature, which allows for continuous operation without having to empty the unit's bucket, but requires a floor-level water drain. Without access to a floor-level drain, if you want to avoid regular emptying of an internal bucket, buy a unit with an internal pump feature that can pump water vertically up to a sink.
Energy performance is rated by the amount of water extracted every hour versus the amount of energy consumed to do so. ENERGY STAR® qualified units remove a very high level of water while consuming the least amount of power.
After properly unpacking the unit and removing all the shipping tape keeping the bucket in place, you should also check the internal bucket to ensure the float switch is not dislodged (refer to instruction manual).
If you choose to use either the direct drain or pump application that some models feature, please make sure to follow the instructions for setup in your owner's manual.
When you turn the dehumidifier on for the first time, set the relative humidity (RH) level to the driest (highest) setting possible to stabilize the room's humidity. Most units have RH settings as low as 30% and as high as 90%. After a couple of cycles, set the unit's automatic humidistat to the setting you desire. In summer, 50% RH is recommended, and as low as 30% RH is ideal in winter.
