Dehumidifier Reviews

Dehumidifiers protect against mold and mildew that are created because of high moisture levels. When the moisture in the air is over 50% the conditions breed dust mites, mold and mildew. This worsens the air quality and aggravates allergies and asthma. The growth of mold and mildew also brings cleaning challenges. Dehumidifiers are great for basements, bathrooms, and other areas that tend to retain moisture. Using a dehumidifier passes the air through the system that removes moisture from the air and deposits it into a tank or reservoir which reduces the amount of moisture in the air. With so many different brands in many different price ranges, these reviews provide a guide for the products that are best, based on your needs.

When you are knowledgeable about the size and situation you want to solve, you can easily equip a high-quality dehumidifier.

What Is a Dehumidifier?

A dehumidifier is an appliance mainly used for extracting excessive moisture in your room or house. There are different types of this appliance – portable, large commercial equipment, and whole-house dehumidifier. It is composed of necessary materials for humid maintenance.  Some of these are exhaust fans, desiccant, ventilators and condenser coils.

Why Do You Need It a Dehumidifier?

Too much humidity can cause too much condensation on windows. It can result to mildewed odors, mold proliferation, insect attacks, and physical damages to wood furnitures, posters and wallpapers. You will experience difficulty in opening cabinets, doors, and drawers. There would be black spots and yellow marks on your wall. It can also aggravate health diseases like allergy, chronic headache and asthma. As soon as possible, it is better to address this problem immediately to prevent any physical damages.

How to Choose the Suitable Dehumidifier?

There is a wide range of choices, which vary in quality and price. You need to consider the dimensions of the room to be treated. You can get the size by calculating for the square footage of the area. You must also consider the available space in the room, desired humidity level, and your budget. Next, examine the machine based on its durability, operational sound level and energy consumption.

What Are the Different Types of Dehumidifiers?

If you have understood the different types of dehumidifiers and the perks you can get from it, it will be easier for you to find an appropriate and practical machine to use. All classes of dehumidifiers function similarly, but the level and quality of service differ. Each dehumidifier can give you different benefits and has different shortcomings. The buyer must know what he is looking for.


Here are the various types of dehumidifiers you can choose from.

  • Portable Dehumidifier

This typical type of dehumidifier is very light and has a plastic casing. The most common portable unit is known as the refrigerative dehumidifier. It makes use of hot and cold loops, a water accumulation tank and an engine. When the engine operates, the air is being pulled by the fan, passing through the cold loop. Then, the condensate is accumulated and the water is being separated with the air and stored in the tank. The drained air passes over the hot loop to keep it warm. After this process, the room temperature is expected to rise, especially if the unit has a high capacity. Some small portable units utilize a Peltier thermo electric energy pump.In this unit, it does not have moving parts and does not make any sound during engine operations. However, this can use up more energy than the usual dehumidifiers.

Another style of portable dehumidifier is a machine that performs electrolysis to get the air moisture. It makes use of a solid polymer ionic casing. Portable units are available in different sizes. As the name indicates, you can easily transfer the machine from one place to another. If you will only use it occasionally, you can easily store it in your basement. The majority of the models operates with a noise produced, which can be compared to a small fan. This type is very affordable.

  • Whole-House Dehumidifier

If you need to treat more than 3 areas, you need to equip a whole-house dehumidifier. It is a stationary machine that can support a large area. The engine can be attached to centralized air systems, which are already installed in your house. For each room, it will use the present vents to extract the damp air. What’s good with this type is that it can remove triple the amount of water that a portable unit can extract. Sometimes, models will no longer accumulate the water in its tank. It will be pulled out from the house via pipes.

  • Chemical Desiccant Dehumidifier

Analogous to a desiccant, this type of dehumidifier utilizes a drying tool such as activated alumina, silica gel and lithium chloride salt. Every unit consists of a revolving wheel. The drying tool crosses the air and consequently, it absorbs the moisture content. The air will be transported to a certain area where the drying tool will be drained and the water will be accumulated and ejected. The process will be done continuously until the ideal humidity level is reached. This unit varies in size and this is commonly used in buildings.

  • Dehumidifying ventilators

Dehumidifying ventilators are usually positioned in basements. Usually, the humidity-related problems arise in the basement. As the machine reached a predetermined amount of relative humidity, the sensor will activate its exhaust fan and as a result, the air outside will be collected inside the house.

  • Commercial Grade Dehumidifiers

This type is versatile as it can either be a portable or a stationary engine and it can use any mechanism of moisture accumulation. This is often used by huge facilities like warehouses and factories.

  • Capacity of Household Dehumidifiers

The capacity of dehumidifiers is commonly calculated by using pints of water as a unit. The measurement is pints of water per day. You will know that the dehumidifiers have high capacities when the work it can do is not typical for its size.

Tips to Effectively Use Dehumidifiers

Portable units are applicable for enclosed rooms. You must close all the doors, vents and windows. You should consistently check for the airflow of the engine. Be sure that there is approximately 12 inches of space between the machine and the wall. The drying mechanism of dehumidifiers is more effective when the room has a good air flow. You can turn on electric fans to keep the air circulating.

Care and Maintenance of Dehumidifiers

You should clean the machine with the use of soap and water regularly. By doing this, you could prevent the proliferation of bacteria and molds. Disposable air sifts should be thrown and replaced with a new one as recommended in the machine’s guide. The permanent filters must be kept clean all the time. Remember to allow the machine to rest sometimes. Allot ten minutes of rest before turning it on.

Everyone can ensure the security of their properties and prevent the spread of illnesses by monitoring the relative humidity in their place. A suitable dehumidifier would be the solution for this. Being careful in selecting a dehumidifier could save you some money and promote healthier surroundings.
