What You Need To Know About Dehumidifiers

The excess of moisture in the walls of houses, clothes, books, and furniture can cause serious consequences for the environment and health, especially for elderly people with respiratory problems and asthma.

How to get rid of moisture from homes, offices, libraries, and other places? A dehumidifier is a device that helps remove excess water from the air either by storing it in a tank or transferring it directly to the drain. The mini dehumidifier is used for the small space and the commercial dehumidifier is used for the large space.

The commercial dehumidifier is similar in appearance to the air conditioner and the mini is a small device. Due to the variety of models, systems, capacities, and powers, the energy expenditure will be determined by the method chosen and the conditions in which the equipment operates.

How it works

Dehumidifiers are devices specially designed to provide an immediate, quick and useful solution to all the problems caused by excessive humidity. It requires no installation in small household equipment and low installation and maintenance costs in industrial equipment.

These devices are able to make the heat not so sticky in the summer and work on the principle of condensation. The humid air is drawn in by the fan and passes through the evaporator coil, leaving the ambience cool and dry.

In this way, the moisture in the air condensate is collected in the condensing case where it is disposed to the drain pipe. The cold and dry air passes through the condensing coil where it is reheated and sent back to the enclosure.

Dehumidifiers are often presented as the only option that helps avoid severe problems with habitability and reduce space use due to high humidity in the air. It even solves domestic issues, “for example, in Raleigh, North Carolina, and other very humid areas are used to dry clothes more economically.”

In the summer, it keeps moisture out of the space, and in the winter it has some of the most important uses. In winter the humidity levels are low so moist air from a humidifier can help to balance the moisture.


In homes, shops, and industries, this equipment not only extracts excess moisture but also allows to maintain the percentage of moisture automatically. It maintains the humidity percentage advisable for human health and comfort, avoiding future diseases and bone diseases, a consequence of a constantly humid environment.

For allergic people, they are great allies, explains Dr. R. Lleonart, Secretary of the Foundation of the SEAIC, Spanish Society of Allergology and Clinical Immunology. Mites, for optimal growth, need a temperature of 25 ° C and a humidity of 85%. In areas of higher humidity, a dehumidifier can significantly reduce the growth of mites and fungi, as long as it is used constantly and in closed places, “he explains.

In this sense, we must take into account that the percentage of relative humidity suitable for comfort and health is between 45% and 55% either in summer or winter. The idea is to get that always, whether or not heating or air conditioning, that percentage is maintained.

Also, maintaining these levels prevents the proliferation of mold and bacteria and the consequent bad odors that are derived from them. Avoid anomalies and damage to electronic and mechanical equipment, such as corrosion; they avoid the deterioration of decorative elements such as curtains or carpets, paintings, scrolls; reduce the ailments of the respiratory tract.

They help prevent health problems such as painful joints or excessive sweating and even prevent the deterioration of organic substances such as food products.

The diversity of models

The technology and performance of these devices are taken into account especially in the industrial sectors, whereas in the domestic sphere, especially in homes and offices, more consideration is given to aesthetics and design.

Which device is the most appropriate? The answer depends on what kind of device you need for your home or business purpose. However, one of the characteristics that differentiate one from another is the size of the device since it can occupy a lot of space.
