Each dehumidifier is rated on various different categories, including but not limited to their size, water storage capacity, energy use, brand, price, noise level, low temperature operation and ease of use.

Why Use a Dehumidifier?

High humidity is harmful in many different ways, and it is recommended that the humidity in a closed space should be 30% to 50%. Humidity can exceed these levels if one lives in humid climates like near coastal areas, or if the location is not well ventilated. To remove the excess water vapors from air to bring the humidity down to the optimum levels a dehumidifier is an essential. Excessive humidity in homes, offices, basements, and other closed spaces can lead to a multitude of serious problems:

  1. Mold and Mildew: Mold and mildew thrive in damp conditions; therefore high moisture level in air encourages their growth. These troublesome fungi are unsightly and can destroy the appearance of your walls and ceilings. They also lead to musty odors, and can damage your belongings like curtains, books, etc. Also mold and mildew are major environmental allergens. Therefore, if you or your family has allergies or breathing problems, these allergens can be detrimental to their health.
  2. Uncomfortable Living Environment: Highly damp condition is very uncomfortable as it makes breathing difficult and results in clingy and sweaty feeling.
  3. Weakened Foundations: High moisture can speed up the rotting of wood. With excessive water content in air the wood furniture and wooden parts of your home’s or office’s foundation will deteriorate faster weakening the structure of your home.
  4. Insects: High moisture attracts insects and centipedes giving rise to bug problems in your home making it look dirty. Insects can also threaten the health of your family.

When getting dehumidifiers one is deluged with many choices. This guide will help you choose the best dehumidifier. Read on for further knowledge on dehumidifiers and for buying advice.

How dehumidifiers work?

Dehumidifier can be divided into three different types based on their working mechanisms:

1. Refrigerant:

GE refrigerant dehumidifier

Refrigerant dehumidifiers, also known as heat-pump dehumidifiers, can be classified as mechanical dehumidifiers and are the most commonly used type. They work in a way that is very similar to air conditioners. The dehumidifier draws in moist air from the surrounding which is passed over a cold coil. The cold coil cools the air and causes the water vapors in it to condense. The water collects in a storage cup or it is directly drained. The cooled dry air is then reheated using a hot coil and returned to the surroundings.

This type of dehumidifier can effectively remove large amount of moisture from the air, but they consume considerable amount of power. The major downside with these dehumidifiers is that they involve moving parts which includes fans and a compressor, which leads to noise. Many brands are working on manufacturing silent dehumidifiers.

2. Electric:

Instead of a compressor, the electric dehumidifiers make use of thermo-electric effect to cool the air. They can also be considered as mechanical dehumidifiers. They consist of two dissimilar metals and electric current is passed through them. This produces cooling effect. These dehumidifiers cannot remove large volumes of water from the air; therefore they are only suitable for smaller spaces. Also, they are less energy efficient. However, electric dehumidifiers do not consist of any moving parts except for a fan, so they are silent.

3. Desiccant:

Desiccants like silica gel have high affinity to water, and they can absorb water from the air when moist air passes over them. Desiccant humidifiers, also known as chemical dehumidifiers, make use of silica gel to dehumidify air.

For larger desiccant dehumidifiers, moist air is drawn in from the surrounding and is passed over a layered rotor. The air passes through channels formed by the sheets on the rotor. The surface of the channel is covered with silica gel which absorbs water vapors from the air as it passes through the rotor. As the crystals absorb water vapors they become deactivated and to reactivate the crystals they are heated by passing hot air over them. The hot air carries off the moisture from the crystals. This moist air is them released in the outside environment. These dry dehumidifiers don’t store any water in liquid form, which means that they don’t need a water disposal system. This mechanism is also used in safe dehumidifiers as they don’t involve any refrigerant.

Smaller chemical dehumidifiers make use of desiccant material stored in a metal casing. They absorb the moisture from the moist air in a small space. The chemical absorbent is then recharged by heating using electricity. They are often used as closet dehumidifiers because of their small size.

Unlike mechanical dehumidifiers, this type of dehumidifiers can work at very low temperatures and they are quieter too because they don’t make use of a compressor. However, they don’t have a high capacity to absorb water.

How to choose the right dehumidifier?

No matter where you would be using the dehumidifier, there are some general factors you should keep in mind when purchasing a dehumidifier:

  1. Size: You must ensure that the dehumidifier you choose has enough capacity to effectively fulfill your dehumidifying needs. A dehumidifier’s capacity is the amount of water it can remove from the air in a day and it is usually measured in pints. To determine the capacity you need you must measure the humidity level of the location you will be using the dehumidifier for and the size of the location. Use a hygrometer to measure the humidity and measure the area in square feet. Then make use of the manufacturer’s sizing guide or Association of Home Appliances Manufacturer (AHAM) sizing guide to determine the capacity your dehumidifier must have.
  2. Storage Tank Capacity: If you are considering a mechanical dehumidifier then the capacity of the storage container is important as well. If the container is small then the gathered water may overflow and you will have to remove the water from the tank much more often.
  3. Energy Efficiency: Dehumidifiers work on electricity. To make sure that your power bills remain low the appliance you buy must waste less energy. When buying a dehumidifier check if it has Energy Star qualification to ensure that its efficiency is above the minimum levels. Read dehumidifier reviews online to determine the energy efficiency of a dehumidifier. The dehumidifier should also have automatic shut-off system, which will turn off the dehumidifier when the desired levels of humidity have been reached. This will help save power as well.
  4. Noise Level: Another important consideration is the level of noise the dehumidifier produces. Some manufacturer’s provide the noise levels in decibels, or if a value is not provided you can browse through reviews on dehumidifiers to choose quiet dehumidifiers. If you will be using a dehumidifier in an industrial environment with a lot of loud machinery or in a garage or basement then the sound produced by the dehumidifier is not an important consideration.
  5. Ease of Use: You should also consider how user friendly the dehumidifier is. You should ensure that the dehumidifier is easily movable and light weight for portability. It should have a humidistat with which you can control the humidity level you require. Also, in case of mechanical dehumidifiers, it should have a warning system to let you know when the storage tank is full.
  6. Maintenance: Like every other machinery, dehumidifier needs maintenance as well. Purchase dehumidifiers that are easy to maintain and repair. For larger dehumidifiers, a continuous water drainage system is recommended. It is much more convenient if one can connect a hose to the dehumidifier to remove the water using gravity or a pump; one will not need to empty the tank. Also, the air filter must be easy to remove and wash.
  7. Low-Temperature Capability: If you are using a dehumidifier in a place where the temperature is constantly below freezing then desiccant dehumidifiers are better options. This dehumidifier works independently of the temperature of the surroundings. If the temperature lowers occasionally then the heat-pump dehumidifier must have auto-defrost feature to prevent the water from freezing up in air passages. The danger of the freezing of water in the dehumidifier can damage it are you might have to invest in costly repairs.
  8. Price and Brand: The price of a dehumidifier can range from $200 to over a $1000. Buy a dehumidifier that adequately fulfills your needs and is cost effective as well, without compromising with quality. Look for dehumidifier sales and deals on dehumidifier to get fabulous discounts. In addition, the dehumidifier must be from a well reputed brand which have great customer service and which offer longer warranties. Make use of dehumidifier reviews to decide which brand you want.

The durability, strength and longevity of the dehumidifier are also some important factors to consider.
