Dehumidifiers

Dehumidifiers are commonly used by individuals who wish to lower the amount of humidity in the air. When a home has excess humidity in it, it can lead to a number of different problems for the homeowner. The house could easily harbor mold and mildew growth and be uncomfortable to live in.

In a home with a high amount of humidity, you might notice a musty odor, and many people who live in these conditions notice that their allergy symptoms are amplified. You might even find stains on the ceiling and walls. It is also not uncommon to find moisture on the insides of windows and doors.

If you are considering purchasing a dehumidifier, there are several things that you will need to consider. If you visit a local home center, there is a good chance that you will find many different models and brands to choose from. Many of these are quality products, and they all have good features about them. However, you do not want to purchase something that you do not need. There are very large dehumidifiers that may not be suitable for a small house. If you have a larger house that you need to remove humidity from, you will want to make sure that you purchase a unit large enough to do the job.

This dehumidifier buying guide will help you navigate the different features of the many dehumidifiers that are on the market. It will provide you with the information that you need in order to make an educated decision when purchasing a dehumidifier for your home.

Types of Dehumidifiers

There are two main types of dehumidifiers that you will need to be aware of. One type of dehumidifier is known as a desiccant dehumidifier. This type of dehumidifier uses desiccant material that absorbs the moisture in the air. This type of dehumidifier is very common, and it is typically used in small applications. These dehumidifiers are the least expensive types on the market, and they come in a variety of models. This type of dehumidifier is also referred to as a passive dehumidifier.

The other type of dehumidifier is a mechanical dehumidifier. This type of dehumidifier utilizes cold air coils as well as warm air coils to treat the air. The air is drawn in and runs over the cold coils. This process helps to collect the moisture on the coils, and then the moisture runs down into a collection pan. At that point, the air is sent over warm air coils in order to warm the air back up to the temperature that it was at when it came into the dehumidifier. In most cases, the air that comes out of of this type of dehumidifier will be a little bit warmer than what it was when it went into the machine. This type of dehumidifier is referred to as an active dehumidifier.

Thermoelectric and Compressor

You will generally see two different kinds of mechanical dehumidifiers to choose from. The first type of dehumidifier that you might come across uses a compressor. This type of dehumidifier works much like an air conditioner. A compressor is used to draw the air across the coils and pump it back out.

The other type of dehumidifier that you might find is the thermoelectric version. With this type of dehumidifier, an electric current goes through metals in order to create heat. The air then passes through the metals in order to have the moisture removed from it.

Dehumidifier Considerations

When you are trying to decide on a dehumidifier, there are several factors to consider:

  • Size
  • Movability
  • Capacity
  • Air filter
  • Humidistat
  • Automation
  • Drainage
  • Cost
  • Maintenance

Size--One of the most important things to consider when purchasing a dehumidifier is the size of the unit. First, you need to take into consideration how big the room is where you plan on putting the dehumidifier. Then you will be able to find the appropriate dehumidifier to match the space that you need. For example, if you are going to put it in a small room, you would not necessarily need to purchase the biggest mechanical dehumidifier on the market. A small desiccant dehumidifier would most likely be better.

Movability--You may also want to determine whether your dehumidifier can be moved from one room to another. Some dehumidifiers are easier to move around than others. If you are going to keep yours in the same spot all the time, this will not be an issue for you.

Capacity--You should also determine how much water the storage tank can hold. After extracting the moisture from the air, it stores it in a tank until you empty it. If you will not be available to empty the tank very often, you should get one with a larger tank.

Air filter--You should take a look at the air filter that is used in your particular dehumidifier. Many of them are washable, which makes them easy to clean and put back into the unit. If you have to continually purchase filters, this can add to the cost of the dehumidifier.

Humidistat--Having a built in humidistat can also be very beneficial. This will allow you to set a particular humidity percentage that you want to achieve, and the dehumidifier will be able to hit that percentage for you.

Automation--You should most likely look for a dehumidifier that is automated. This will allow the unit to shut off when it is done working.

Drainage--Some dehumidifiers utilize a built-in drainage system that will make things easier on you. With this type of system, you can hook up a hose to the unit, and it will automatically drain itself.

Cost--The cost of the unit is another important factor. You should set a budget and try to stick with it on this purchase.

Maintenance--The maintenance associated with the unit will also be important. Some dehumidifiers require more maintenance than others, and you should try to find one that does not require a lot of work on your part.
