Humidity has a very important effect on the comfort inside your home during the Winter & Summer. Weather forecasters in the summer talk about the comfort index, which attempts to show how much hotter the air temperature is likely to feel to you because of the humidity. As the humidity increases, the hotter you will feel. One of the ways air conditioners operate is to remove humidity from the air, which makes you feel cooler. This is an important part of climate control. In winter it gets a very dry cause of hot air & we need to maintain a certain level of humidity to keep our skin healthy & feel comfortable & also to keep the wooden furniture & floor in good condition.
