Here’s a nice low-tech solution to a pretty common problem. If your home uses forced-air heating you’ve probably had to deal with the issue of dry air. Sure those fancy, expensive plug-in humidifiers will solve the problem but why not reap the benefits of grade 2 science instead.
Simply fill this non-electric humidifier with 1.6 gallons of water and sit it on top of a standard floor register. The heat from the register evaporates the water and the rising hot air draws the moist air throughout your house. It apparently uses a wick of some sort (which probably absorbs the water and allows the hot air to pass through) that needs to be replaced on a monthly basis. The best feature of course is that this humidifer runs completely silent.
The Non-Electric Humidifier is available from Gaiam for $30.
