Types of Dehumidifiers

Types of Dehumidifiers include:

Desiccant dehumidifiers use absorption to remove moisture from the air. It uses a desiccant wheel or silica gel to absorb water. It comes in different sizes.

A desiccant dehumidifier does not use a compressor or a cold surface to absorb moisture from the air. Instead, it has a desiccant wheel, which collects moisture from the air in the same manner as a sponge. 

Some of them use silica gel to absorb moisture. They come in different sizes. They can be small enough to fit in a gun safe or big enough to dehumidify a room, even a whole house.

Energy-efficient dehumidifiers use 15% less energy than standard dehumidifiers. They can save you money. 

Energy-efficient dehumidifiers are usually ENERGY STAR certified. These use about 15% less energy than a standard dehumidifier.  Energy-efficient dehumidifiers are some of the best. 

They save you even more energy than traditional models. You can save money and reduce your carbon footprint as they conserve energy.

A drain hose is used for the dehumidifier to continuously drain. It drains from the water bucket into a floor drain using gravity. 

Some dehumidifiers come with a drain hose option for continuous drainage. A drain port on dehumidifiers are linked to a regular garden hose. This permits collected water to drain to a floor drain continuously. 

The unit drains by gravity. So, the hose must be laid on the ground and trimmed to the shortest possible length.

A self-draining dehumidifier has a pump that forces the water out of the water bucket and into a sink or out a window. It pumps up to 16 ½’ away. 

This is the dehumidifier with an inbuilt pump that expels condensed water automatically. Its powerful pump can force water into a sink or out a window from up to 16 1/2′ away. 

They remove the need to empty a water tank and make it suitable for basements without floor drains. If the hose is blocked, the tank control mechanism shuts the unit down. This makes it essentially maintenance-free.

Air Purifier dehumidifier works both for reducing humidity indoors and removing allergens, dust mites and pet dander from the air. 

A dehumidifier and an air purifier combo can help you get cleaner air in your house. Air purifiers use filters to remove allergies, dust mites, and pet dander. 

They also remove other unpleasant particles from the air. The combination creates a more pleasant and secure environment at your location.

Quiet dehumidifiers do not have the compressor noise. They work well in living spaces and you can sleep with one running. 

Quiet dehumidifiers don’t make the normal buzzing or whooshing noises. The rotating fans are constructed in such a way that the acoustic quality is controlled. 

You can sleep with the dehumidifier working.

Humidifier-Dehumidifier device has a humidistat. When it is too humid the dehumidifier function works, and when it is too dry the humidifier starts. 

Humidifier-dehumidifier Combo has an automatic humidistat function. Whenever humidity levels drop low, the dehumidifier function stops. Then, the humidifier function kicks in. 

The reverse is also true. With these two appliances, you can have superior air quality all through the year.

An Air Conditioner dehumidifier removes humidity in the air while releasing cool air. 

This dehumidifier removes the excess moisture in the air first. Then, it circulates the air through the air ducts. You get the dual benefit of cooling your air as well as removing excess moisture.

Too much indoor moisture causes mold growth and a  dehumidifier helps prevent mold from developing. 

Dehumidifiers remove excess moisture from the air, preventing mold growth. Dehumidifiers don’t destroy mold, but they do keep it from growing into a problem.

A portable industrial dehumidifier is a large dehumidifier that has a handle and wheels to move it around. 

The Desiccant Industrial dehumidifier is large in size. It has a folding handle and caster wheels. This makes it easy to move around, hence is portable. 

It is free-standing and energy-efficient. It can function at extremely low to high humidity levels. It is also a low-temperature dehumidifier that can work at a degree or two below freezing point.

Dehumidifiers that work well in low temperatures even as low as 2-degrees are desiccant dehumidifiers. 

Desiccant dehumidifiers are the best low-temperature dehumidifiers. They can work in extremely low temperatures, even lower than 2-degrees and below. They do not freeze over.

Battery-powered dehumidifiers are codeless and usually for small spaces. They have rechargeable batteries. They last for 4-6 hours. 

Battery-powered dehumidifiers have a cordless option. They can fit into small spaces like cabinets or drawers. It is compact, and the battery lasts between 4 and 6 hours.

Humidistat or Hygrostat Dehumidifier

A humidistat monitors and manages the humidity in the air near the dehumidifier. The humidistat ensures the room is never over-dehumidified or under-humidified.
Humidity levels in other areas of your home are not measured.
When the relative humidity reaches the desired level of humidity, the unit will shut off. When the humidity is too high it will kick back on the device and reduce moisture.

Dehumidifier With Humidity

The purpose of a dehumidifier is to reduce the humidity in an indoor space. Relative humidity is the amount or percentage of water vapor in the air. Excessive humidity causes discomfort, health issues, and damages property.
Humidity is not all bad, but it does need to be under control so that the space is livable. An ideal relative humidity range is about 50%. An ideal humidity means you breathe easy.
There are issues with low humidity. Air that is too dry drier out the nose and throat. Very dry air makes people susceptibile to colds and respiratory illness. Low humidity can damage woodwork and furniture.
There are also issues with high humidity. Damp air leads to condensation on walls and windows. Air that is too wet can lead to mold spore blooms and allergens like bacteria.
Low Temperature

Low Temperature Dehumidifier

It is common for refrigerant dehumidifiers to develop ice. Ice builds on the appliance’s coils up when units run at low temperatures.
If you live in an area where it is cold or snows a lot consider a desiccant dehumidifier. Desiccant dehumidifiers run better at low temperatures compared to refrigerant models.

Desiccant dehumidifiers can work in extremely low temperatures, even lower than 2-degrees.

A defrost feature is ideal for refrigerant dehumidifiers. The low temperature switches from dehumidifying to defrosting when it senses ice. When the frost is gone the dehumidifier resumes operation.
