During summer days, people complain of heat. To make themselves comfortable, they drink lots of water to feel cool inside, turn the electric fan on to dry up the sweat, and plunge in the pool to freshen up and cool their bodies from the surface. However, there are days during summer that these cooling up activities won't work; especially when we are inside our homes. These are the days when the air is humid.

Heat pump dehumidifiers are complex, low-production machines and are not low-cost items. Spring seems to be the best time to buy: in the last few years dealers have held sales early in the spring with savings of $50 to $100.

The more water a dehumidifier holds which is measured in litres or U.S. pints a day the more it costs. You pay more for special features.

A refrigerant dehumidifier with air conditioner is a best buy if you are in an area where the temperature during the year is mostly in the higher scale of the thermometer than in the lower scale. Refrigerant humidifier not only lowers the air humidity to 45%; it cools the air too during hot days. It helps climb up temperature without making the air too dry.

If you are, however, lives in a cool to freezing area, a desiccant dehumidifier will work for you best. A desiccant dehumidifier does not cool the air in the same way as a refrigerant dehumidifier does; it only controls the humidity level. But it controls the humidity automatically; lower it or put it up higher. It decreases humidity when the humidity is high (this is during hot or beginning of rainy days) and increases the humidity when it is too low, which is during crisp, windy or winter days, to make the atmosphere feel warmer.

Don't try to save money by buying a unit that does not have automatic defrost. If a room is too cool, a dehumidifier can frost over and stop removing moisture. A frosted-over dehumidifier left running for a long time will break down. If you want a great way to run your dehumidifier into the ground real quick, this is the way to do it.

Get a unit with a two-speed fan. They are quieter at lower humidity, which reduces the nuisance factor and believe me when you hear one of these things go for long periods of time you will relish some quiet time. Test all units in the store for noise level, especially if you plan to use one in or near a bedroom.
