What is a dehumidifier?

      Comments Off on What is a dehumidifier?

A dehumidifier is an electrical appliance that helps in the removal of moisture in the interior air. The dehumidifiers come in different makes and models, capacities and sizes. This includes the whole house models that are designed to work with the home heating system and the portable dehumidifiers that can be used anywhere in the house where there is a moisture problem.

A dehumidifier can also be a part of a portable air conditioning system (multifunction).

The most common types, however, are those that are portable and are designed solely to get rid of the moisture from the rooms of a house. To put it succinctly, a dehumidifier will do the exact opposite of what a humidifier (adds moisture to a room), removes moisture from a room.

Having too much moisture in a home can trigger the growth of mold and mildew. Excessive moisture can cause adverse effects to the musical instruments (wooden) and the furniture, carpets, textiles and clothing. Now while you can get rid of the water that has seeped into your home during the heavy rains with a vacuum, there are some amounts of moisture that are bound to be left behind. Heat can get the job done, but a dehumidifier will speed up the drying process a great deal and will get rid of all the moisture, providing a more permanent solution.

Some portable dehumidifiers pull in the moisture from the room and into a water tank which has to be emptied and removed regularly. Other dehumidifiers, on the other hand, expel the moisture directly into the sewage pump or out of the house through the basement window. You could always set a humidistat. It is a great feature that you may wish to have.

Things to consider while reading dehumidifier reviews

For the fact that it will improve the quality of air in your home, you should be out and about shopping for one. However, before you jump right into the market for one, you should read some reviews first to get some insight on which would be best for you. Though they are not complex machines, dehumidifiers do come in a wide variety of makes and model, shapes and sizes, features and technologies. Below are some factors that will help you to determine which is best for you while reading the reviews that will follow.

  1. Dehumidifier size

This is a factor that should be of concern to you. You should pick the space where the dehumidifier will operate. For you to get the right size and fit for your dehumidifier, ensure that you know the exact square footage of the area or basement that you intend on dehumidifying as well as have a rough idea of the room’s moisture levels. The drying capacity of a dehumidifier is measured in the pints of water that it can get rid of in 24 hours.

  1. Humidity control

You should choose a humidifier control that has automated controls to help monitor the humidity levels and set the desired humidity level. The optimal humidity levels during the summer for your home should be between 40% and 50% during the summer and 30% and 50% during the winter. There are some dehumidifiers that contain inbuilt hygrometers that measure the relative humidity and then display the numbers. Still there are those that have an adjustable thermostat that you always dial to your desired humidity levels and then the unit will automatically maintain the humidity to the set levels.

  1. Water capacity

You should always put into consideration the bucket size of the unit. The dehumidifiers with larger tubs need to be emptied less often. However for such convenience, you should expect to part with a considerable amount of money. A golden rule for this is the more water a dehumidifier can suck from the air and hold the more it is likely to cost you. Be ready to shop around as the prices tend to vary greatly. Those that have the front loading buckets are by far the easiest to empty.

  1. Defrost features

You should always prefer a dehumidifier that can work even at low temperatures. Unless you reside in an area that is warm all the year round, you should consider a system that has the defrost feature. The heat coils in the dehumidifier tend to frost when the indoor temperatures are too low. To work around this, you should get Energy Star certified units 45 to 40 degrees. Though you will pay a little extra for this defrost feature, it will cut the cost of having to repair the damaged coils.

  1. Quiet operation

It is no secret. Noise can be and is a nuisance, especially when the dehumidifier is situated close to a bedroom. Dehumidifiers that feature two-speed fans operate quietly in the lower humidity levels and also tend to be able to save on costs. Test a dehumidifier on its noise levels before you make a purchase.

  1. Mobility

You should ensure that the dehumidifier that you get can be moved from one room to the next. For this to happen, get one that has casters and a long power cord. This way, you will be able to place it anywhere it is that you want it.

  1. Automatic shutoff

Those dehumidifiers that have the Energy Star label will save you a great deal when it comes to utility bills. The dehumidifiers that are certified with this label are guaranteed to use up less energy and still be very efficient.

  1. Washable filters

There are some models that normally contain filters to protect the coils from dust, dirt and other debris. Ensure that you can easily remove and replace the filter for washing, a task that you should be able to do at the very least twice in a month. This will help the filters to last longer and get rid of the constant replacement of the filters.
