If it isnt possible to completely replace the homes insulation, caulking or sealing windows throughout the home can be another effective way to restore the home to a more ideal inside humidity level.

The hotter the air is, the more water it can contain. Relative humidity refers to the amount of water in the air compared to the amount the air can hold at a given temperature. If you're an outdoorsy person or just particularly sensitive to that clammy, damp feeling you detect outside, it's vitally important to understand the difference between relative humidity (RH) and dew point, because the latter will actually give you a better idea of just how quickly you'll become uncomfortable with any exertion. The automatic shut-off and full tank alert will let you know when the 2-gallon capacity bucket needs emptying. During the summer we consistently have humidity levels in excess of 80% .
