Deploying a dehumidifier in damp areas of your home is an easy way to not only boost your comfort but also to prevent a number of problems, including sickness, mold and mildew growth, and damage to your home and its furnishings.

My own “FOBFU”—find out by fouling up—lesson illustrates why it’s smart to use a dehumidifier. I stored a bunch of camping equipment in my basement, which tended to be very humid. When I went to retrieve a sleeping bag for a camping trip, I found it ruined by the damp environment. I immediately went online to read our recent report on dehumidifiers. It turns out you can get a capable model for about $140 dollars—and perhaps even less if you combine it with a rebate or tax credit by buying an energy-efficient version.

Most dehumidifiers have features such as a built-in timer, which can be useful in some situations, and a hose-attachment point to drain the water, eliminating your having to empty a reservoir. One model even comes with a pump and plastic tubing that sends the collected water out a window or up to a slop sink or other high drain. Other factors to consider when buying a dehumidifier include energy use, noise, performance in brownout conditions, and the ability to automatically restart after a power blackout.

I’ve learned my lesson. My new dehumidifier is now humming away down the basement, keeping my camping gear in good shape.—Gian Trotta
