Dehumidifiers ensure a pleasant home environment during hot and humid weather conditions. Here we have reviewed the best dehumidifiers of different types, including desiccant dehumidifiers, mechanical dehumidifiers, and dehumidifying ventilators, from brands like Honeywell, Eva-dry, etc.

In a tropical country like India, the weather remains hot and humid for most parts of the year. Humidity, in a very simple form, can be described as the presence of water vapor and moisture in the air. High humidity makes the weather unpleasant, unbearable, sweaty, and salty.

Although air conditioners reduce the temperature to a satisfactory extent but fail to decrease the water vapor levels and thus, the uncomfortable surroundings prevail. As they say, technology has the solution for every problem, to combat the sticky weather conditions you are tired of, “Dehumidifiers” emerge as the Messiah!

Dehumidifiers are the appliances that decrease the level of water vapor in the air, eventually reducing the humidity and making the environment pleasant and amicable. High levels of moisture serve as the thriving point of dust mites, molds, and other allergens.

Using dehumidifiers leads to the removal of such undesirable living organisms from your periphery. Prolonged warm and humid conditions lead to the proliferation of such allergens and are potential threats as well.

Such organisms become one of the major factors for the bad and foul odor in the houses, basements, store-houses even in living rooms. For all such issues, dehumidifiers become inevitable to ensure your amiable living conditions.

In this article, we will explain to you why dehumidifiers are needed and what are the factors you need to consider before buying one.  You will also know what are the different types of dehumidifiers and how dehumidifiers work? We have provided a list of 6 best dehumidifiers available online.

Top 6 Best Dehumidifiers

Need of Dehumidifiers:

  • Decreasing humidity: The moisture in the air can be excellently dealt with and reduced using dehumidifiers. Increased levels of water vapors make your day unpleasant, and the ambiance is not well accepted.
  • Dealing fungus and allergens: Warm and humid atmosphere make the dust mites, fungus, and molds sustain and reproduce at a faster rate. They can change eventually, make your lifestyle adverse by invading your body through food or contact. Reducing the humidity ensures you to get rid of them!
  • Water stains: In closed rooms, high humidity leads to water stains on walls and furniture that ruin the look of your dream place and create additional issues.
  • Bad odor: Humidity coupled with fungus and allergens lead to foul smell, and prolongation of such conditions cannot be solved using room fresheners as well. To solve the root cause, dehumidifiers become necessary.
  • Allergic Reactions: The dust mites, mold spores, fungus, and other microbes are potential allergens, and the proliferation of such undesirable species may lead to health issues.

How Does Dehumidifier Work?

The primary and basic job of dehumidifiers is to decrease the humidity of the atmosphere by regulating the moisture level in the air. Decreasing the humidity makes it inhospitable for the thriving mites, molds, fungus, and other harmful allergens.

The mechanism that these appliances follow is pretty simple: condensation. The water vapor present in the air, which is in gaseous state condenses into the liquid state; as a result, the moisture content in the air decreases, and the air around you becomes pleasant, and you get your non-humid atmosphere.

The humid air from the surroundings move into the dehumidifiers through the inlet/fans and passes by the refrigerant cooled coils. The warm and humid air cools down due to these coils; as the air becomes colder, the ability to hold water vapors declines. This results in condensation of water vapors into water reducing the moisture content in the air.

This condensed water gets collected in certain chambers or outlets. The water is either removed periodically, mechanically, or drainage pipes are preinstalled for drainage of the water at regular intervals. Pumps are used for the removal of the condensate.

The new cool air with reduced moisture content is slightly heated and the warm, yet the non-humid air is discharged into the room. The air is slightly heated to maintain the efficiency of the dehumidifier at an optimum level. This simple yet effective strategy keeps your home safe from bad odor and harmful pathogens.

Types of Dehumidifiers:

Mechanical Dehumidifiers:

These types of dehumidifiers use refrigerated cooling coils that help in condensation of the humid and warm air that leads to a reduction in moisture content in the air. The condensate is then removed either mechanically or by installed drain hose pipes.

These dehumidifiers are quite effective for all types of weather conditions and all rooms. They come with different capacities and sizes, satisfying the varied multitude of needs.

These appliances can be either used in units for specific rooms or can be centralized and fixed for the entire house. They have certain classifications again, depending on the availability of the drain hose pipes that act as the outlet for expelling the condensate.

In other cases, the chamber needs to be emptied mechanically. Certain dehumidifiers come with an automated system where it stops when the water collecting chamber gets full.

Desiccant Dehumidifiers:

These dehumidifiers contain desiccative substances that have an affinity for moisture or water vapor. These dehumidifiers come handy and portable. But they are not as effective as the electronic\mechanical dehumidifiers and do not reduce moisture to a large extent.

They can be used for short intervals at certain locations like bathrooms, cars, or washrooms. They are much cheaper than the rest of the dehumidifiers and need no maintenance cost. They contain certain hydrophilic substances like silica gel that adsorb the water molecules from the air and reduce the humidity.

Dehumidifying Ventilator:

These types of dehumidifiers majorly help in the removal of humid air instead of reducing the moisture content. They work by using an exhaust fan that expels air outside the room and filling the room with acceptable or pleasant air from outside.

These dehumidifiers can be used in closed rooms like storerooms, basements, or other such places. They are cheaper than mechanical dehumidifiers and need less maintenance as well. But their effectiveness is not quite satisfactory because the moisture content is not reduced by them rather only expelled from the room, bringing less humid air into the room.

Buyers’ Guide

While choosing the appropriate dehumidifier, you need to look for certain parameters:

Size of the unit

Dehumidifiers are easy solutions for high humidity levels. When deciding to buy a dehumidifier, the first thing that needs to be considered is the size of the unit required. For very high humidity issues, you might need a centralized dehumidifier that uses your home’s cooling and heating system to control the entire house’s humidity level.
If the humidity is periodic and limited to localized areas of your house, a portable dehumidifier that serves a single area is perfect.

Washable filters

Few models have filters that protect the dehumidifier’s coils from dust and dirt. You can remove the filters and wash them. This cleaning needs to be done twice a month. This will reduce the cost of filter replacement now and then.

Moisture Removal Rate:

This becomes the basic and most important criteria to know the efficiency and characteristics of the dehumidifier. Usually, the dehumidifiers are categorized based on the number of pints of moisture removed per day.

Greater the humidity your experience, the greater the pint of moisture is needed to be removed. Additionally, the dehumidifiers with a greater magnitude of moisture removal rate take less time in reducing the moisture content.

Coverage Area:

Usually, dehumidifiers come with ratings in square or cubic footage. The size of the dehumidifiers depends primarily on the humidity levels and size of the room. The decision should also incorporate the airflow conditions of the area is well ventilated, and the room with good airflow has less moisture content. Usually, 50-70 pint dehumidifiers can acceptably reduce the moisture content in normal-sized rooms.

For example, when the room is slightly damp, and the room is about 1000sq. Ft, a 30-pint dehumidifier is a wise option. On the other hand, you might require a 50-pint dehumidifier for wet weather conditions.

Temperature Range:

If your room experiences a very wide range of temperatures, you need a dehumidifier that can be operated over such range. Features like defroster should be taken care of while you are concerned about the temperature ranges.

Availability of PUMP:

The condensate needs to be removed periodically from the chamber. Not all dehumidifiers come with an automatic drainage system; sometimes, you need to remove the water mechanically, which might be inconvenient. You might look for the dehumidifiers with proper pumping and installed drain hose connection.

Energy Usage:

Centralized dehumidifiers may charge you a huge sum of electricity bills. Hence energy-efficient dehumidifiers should be prioritized. The energy-saving ratings should not be ignored, as well.

Noise Level:

Although dehumidifiers are less noisy than ACs, noise can be the determining point of your decision. Less noisy and ear-friendly dehumidifiers get an edge over the others because it is all about comfort!

Ease of Use:

While buying the dehumidifier, you need to take care of the sophistication of its usage. Mobility and portability become a major criterion under this. Other features like drainage, water level control are also important.

Brand and Warranty:

A trustworthy brand’s dehumidifiers should be prioritized because they have been ensuring quality products for many years. Warranty periods are also crucial while choosing electronic devices.
