How Does a Dehumidifier Work?

How does dehumidifier works?

This modern technology does nothing but help to make you comfortable by removing excess moisture.

Dehumidifiers have a fan inside them. As it works, air passes through the cooling coils which helps lower the temperature. At this time, the air no longer has excess moisture. It is warmed and pushed back into your room.

The dehumidifier removes the moisture and dumps it inside the water tank. Some dehumidifiers have water tanks, and some have water hoses.

Those units with water hoses permit you to drain the water directly to a sink or outside. Those with tanks require manual emptying.

If your unit has an auto shut-off function, it will automatically shut down when the water level gets to its peak.

Benefits of Using a Dehumidifier

If your home air is too moist, your electronics may be damaged.

Moreover, excess humidity favors the growth of bacteria like mold spores, mildew formations, dust mites, viruses, bacteria, and more. Too much indoor humidity is tough on allergy and asthma sufferers, including people with COPD and similar lung issues. The odor in your closet and your basement may be a result of excess humidity. Health problems associated with high humidity include:

  1. Breathing problems, such as wheezing.
  2. Stuffy nose and sinuses; sneezing.
  3. Watery and itching eyes.
  4. Some skin problems.

Various Functions of the Features in a Dehumidifier

  1. Timers: This lets you set the length of time you want the machine to work. Some dehumidifiers have a restart function in case there is a power outage. This simply means the unit will start running again automatically.
  2. Automatic Shut-off: This is an outstanding feature in any dehumidifier. It helps to turn it off when water reaches the capacity of the tank. If you are busy or asleep, it can help prevent a range of serious safety concerns.
  3. Control Settings: These controls let you choose your preferred humidity level. Normal indoor humidity level is within the range of 35 to 50 percent. You will find some dehumidifiers have digital controls. Others have knobs. Make sure you choose the one that will meet your needs.
  4. Filters: Filters help to remove dust and other particles from the air. However, they need to be replaced occasionally. Every manufacturer has different specifications as to how and when to clean or change filters. Each dehumidifier brand uses different filters sizes and types.

Humidistats Vs. Hygrometers

Humidistats: Most advanced dehumidifiers have a built-in humidistat. These features let you program moisture level. Humidistat is similar to a thermostat which people used to set their furnace temperature. However, if your machine is not equipped with a humidistat, you can purchase one separately on Amazon at a reasonable cost.

Hygrometers: Hygrometer tells the amount of moisture present in an area. This device can be built into a humidifier or dehumidifier and can be used alongside the humidistat. Whether a manual or digital readout, you can get either of them on Amazon to hang on your wall. They usually function with battery.


Dehumidifiers vs. Humidifiers, Air Purifiers, and Air Conditioners


A dehumidifier is a machine used for the removal of too much moisture present in the air. This device is useful particularly in the summer or in the humid climates to normalize the air.

Dehumidifiers have the capability to prevent the development of bacteria and mold. Some allergy and asthma sufferers who are sensitive to excess moisture may benefit from this type of product. It can help prevent wood from drying out and keep your clothes from smelling. They also can help prevent bacteria from growing in your home and causing damage.

The device works by drawing the air and passing it through an evaporation process. This enables the excess humidity to be turned into water. Finally, the water drops into the drain hose or bucket, and the dry air is forced back into the room.

Air Purifiers

This device is used to purify the air by getting rid of dirt and other small pollutants, including some that may cause disease. This process is completed by a HEPA dust filter.

This machine can be good for those prone to allergies or with a history of asthma. As soon as air enters the purifier system, it’s purified and brought back to the home. It can eliminate odors, such as musty smells or smoke odors.

Some air purifiers have ionizers. In these machines, negatively charged ions are released into the air which helps to neutralize positive ions and to help pull dust into the unit. Some of the harmful particles it can help reduce include mold, dust, smoke, and other kinds of micro-organisms in the air. The ions can help trap particles in the air that may be dangerous to your health. The positively-charged plate in the purifier attracts and holds the harmful elements.

Computers, televisions, fax machines and other electronics release harmful positive ions into the body. Placing an air purifier in locations with these devices is wise. Negative ions help to double the oxygen level in the air, reducing awful odors, germs, and dust.

Air Conditioners

Air conditioners and dehumidifiers are not the same things. You cannot use an air conditioning unit to replace a dehumidifier. A dehumidifier cannot be used in place of an air conditioner.

How do air conditioner and air dehumidifier work?

A dehumidifier is an appliance used in the home to remove moisture in the air, while air conditioners blow out cold air. In addition, dehumidifiers draw moisture from the air into the machine before releasing the air back into the home.

On the other hand, air conditioners also promote the drying of air just like a dehumidifier system but work differently. Air flowing through the cooling coil becomes cooler. The compressor then pumps it through a pipe into the condenser. The unwanted heat exits via the coil and the capacitor into the outside air. The condensed water in the air conditioner evaporator flows out through a narrow tube into the outside world.

Dehumidifying Efficiency

Since air conditioners work as desiccant dehumidifiers, they are used sometimes as temporary dehumidifiers. As a matter of fact, the moisture is extracted by desiccation into the exhaust flow. This increases the temperature of the air. An air conditioner is designed with a moisture wick and the energy saving result is not like that of a dehumidifier, which are machines designed specifically for this purpose.

Most air conditioning units are equipped with thermal control systems instead of a humidistat that is used to control dehumidifiers. Still, the humidity and temperature in a closed space are closely associated with one another. An air conditioner can also mask the humidity in your home.
