The best dehumidifier units

Choosing the right dehumidifier is one thing you should never leave to anybody because there are important features you need to put into consideration. Among the special considerations to look after when choosing are the room and pint capacity as the 25-pint unit is only good for small bedroom or living room, the method with which you wish to remove the collected water, and the energy performance of the unit.

There are variable features also that you can look after as you choose such as the drain feature which allows operation at a continuous flow without the need to empty the bucket regularly as it has a pump that directs the water to a sink or to any draining system.

Rooms with minimal activity would need smaller unit of dehumidifier while rooms with larger areas and usually crowded with people may need larger unit. If you are an eco-save buyer who wishes to save on energy while getting hi-speed performance, you should look for a unit with Emery Star rate because it can remove a very high level of water as it performs fast at less power consumption. It should also have a humidistat that automatically shuts off the unit once the desired humidity level is attained. For locations with low temperature climate, low humidifier level is suggested, while a larger one is best for areas located with high temperature climate.

A typical unit should have washable air filter, adjustable fan, frost sensor, signal light, auto-off, and wheel. As you choose a dehumidifier, always go after the one that will meet your needs and the factors that may affect its use and performance, especially since these units are expensive and choosing one on mistake may cause you a lot of regrets.

Different Types of Dehumidifier

Compact Dehumidifiers

Compact dehumidifier is a portable one because of its lightweight feature and it usually has a wheel that is easy to maneuver and a power cord that is easy to utilize. It is possible to move the unit from one room to another so you would not need to buy one for each room of your house, especially if the space is a petite one and you seldom use the other rooms. The average range of pint capacity of this type of unit is 20-50 pint per day.

Basement Dehumidifier

Basement dehumidifier is the perfect unit for homes with basement or water drainage issues like seasonal flooding and mold and mildew problems. This is designed with features like automatic drain hoses and extra high performance for higher temperature locations. The average capacity is 50-80 pint per day.

Whole Home Dehumidifier

Whole home dehumidifier is a larger unit and is more expensive because it is designed intended for larger areas with its high performance level. This is very ideal for large homes where humidity is at high level, and it can protect any surfaces in a home from any mold and mildew, rust and rot, and may help preserve the condition of furniture and frames. The average range of capacity is 80 and above pint per day.

Dehumidifier Methods


The compressor dehumidifier is a common one that uses a compressor for its cooling coil. It may tend to function at moderate energy efficiency for small to large areas, only that it sounds louder and it needs extensive maintenance in order to function well.


Thermo-electric dehumidifier is a unit that works with the use of dissimilar metals and electric current instead of cooling coils. It is less efficient in energy consumption and ideal only for small areas but it has reduced noise.


Desiccant dehumidifier uses natural desiccant such as silica gel in absorbing moisture, which is why it is referred to as non-mechanical dehumidify technology. It absorbs humidity but does not cool the air; therefore it is more efficient in energy consumption and requires less maintenance for proper function.
