A dehumidifier is used in households to reduce the humidity levels so that the residents of the house are able to breathe in good quality indoor air. Among the different types of dehumidifiers are the desiccant dehumidifiers which work in a slightly different way than other types. Here is a look at how these systems work and how you can choose the best dehumidifier.

What is a desiccant dehumidifier?


These units use desiccant materials such as silica gel to absorb the water vapor. They help in maintaining the humidity levels in the range of 30 to 50 percent which is ideal to maintain the quality of the indoor air. If you are living in an area where there is a lot of weather fluctuation and you don’t know when to put on the unit and when to put it off, these desiccant dehumidifiers are ideal for you. The maintenance required in these units is also less compared to the other types and you also don’t have to empty the internal reservoir way too often.

How to choose a good desiccant dehumidifier

Here are a few points that can help you choose a good desiccant dehumidifier:

Desiccant materials are used in a rotor form in these dehumidifiers and these rotors are made from alternate layers of flat and uneven sheets covered with the desiccant. These sheets form axial air channels which run parallel through the rotor structure. Air passes through these channels and the moisture is transferred to the desiccant. Since the air is passing through this desiccant rotor, it is necessary that the rotor is non-toxic and eco-friendly.


A desiccant dehumidifier usually has four other major components besides the desiccant rotor. These are a fan to move the moist air through the desiccant rotor, a fan to move the hot air through the desiccant rotor, a heater that heats up the air for regeneration of the desiccant material, and a mechanical device to slowly rotate the desiccant rotor. If any of these components is of poor quality, your desiccant dehumidifier will not work effectively or will break down soon. So, ensure that the components are of good quality.

Do not go for cheap and low quality rotors. A good quality rotor can last up to 10 years when operated continuously.

While buying a desiccant dehumidifier, consider the size of your home or office where the humidity level is to be kept low. For a larger area, you may want to buy more than one unit to make sure that the dehumidification process works well.


Desiccant dehumidifiers are usually small in size, so buy one that can be easily placed in your office or room and does not occupy much floor space. If you want to further save floor space, you could consider a model that can be located in your ceiling..

Recent desiccant dehumidifiers look better and have a better structure also. So, choose an option that goes well with the look of your house or office.

Since the effectiveness of this type of dehumidifier depends on the desiccant material used, find out if a powerful absorbent has been used in the unit.

A desiccant dehumidifier is suitable for a small office space or a small room and if properly maintained can last for many years. It can also be used along with the cooling medium installed in your home or office which can provide you with deep drying at low rates of humidity. So, if you are looking for a dehumidifier, consider buying a desiccant dehumidifier.
