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-prices 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 however you live in an area which is colder you will need to get yourself a desiccant dehumidifier. This type of dehumidifier will only control the humidity of the air. It does not affect the temperature in any way. It will control the humidity so that on warmer days it lowers the humidity and on colder days humidifies the temperature so that the environment is comfortable.
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.
Get a unit with a two-speed fan. They are quieter at lower humidity, which reduces the nuisance factor. Test all units in the store for noise level, especially if you plan to use one in or near a bedroom.
