Desiccant dehumidifiers aren’t really what we can regard as standard products, which means a lot of people don’t even know many things about them. If you are looking to buy a desiccant dehumidifier for the first time, you need to equip yourself with every necessary information, which is what we aim to help you with here.
How do desiccant dehumidifiers work?
These types of dehumidifiers operate by using desiccant material. Simply put, desiccant substances like the silica gel bags usually found in clothes or electronic boxes are very magnetic to water, and they basically strip humidity from the atmosphere. The desiccant material is hung on a pivoting disc. The air from the room blows on to one portion of the disc, thereby absorbing moisture. Then, the disc pivots until it’s exposed to a warm blast of air, which gets rid of the humid, where it’s collected in the auto-drain pipe or in the tank. With this, the desiccant material is reactivated and the procedure cycles regularly in this way.
Features to consider while choosing a desiccant dehumidifier
Before deciding to select a particular model, there are some essential factors you must think about. Below are some of the most important factors a buyer must take into consideration:
Water tank capacity/volume of the absorbent
One of the most critical factors you must consider when buying a desiccant dehumidifier, or even any dehumidifier, is its water tank capacity. In general, the higher the moisture extraction’s rate, the more the water the tank will be able to contain. A larger capacity gets rid of the need to empty the water tank frequently. In addition, a larger capacity means the desiccant dehumidifier will have a larger coverage most times.
Another important feature you must look before making your purchase is the coverage area of your intended unit. In order to get the ideal unit for your space regarding coverage area, simply calculate the size of where you intend to be using it, and find a model that can process of air volume in that space effectively so that you don’t end up choosing an underperforming model. Manufacturers usually indicate the coverage area of their products.
Also called moisture extraction capacity, the dehumidification performance is quantified by the amount of moisture the machine is capable of removing from the atmosphere in a day. This should be one of your determining factors when choosing the right model for your needs. If there is a very high level of humidity at your home, we recommend you to choose a unit with a high dehumidification rate, like the EcoSeb DD122EA-SIMPLE Desiccant Dehumidifier which absorbs fifteen pints of humidity from the atmosphere daily.
Sound level for larger models
Noisy machines can be very disturbing, particularly if its located close to a bedroom. These units operate without remigration systems and compressors, which makes them perfect for people in search of quiet-operating units. They absorb excess humidity from the atmosphere by extracting water molecules into a desiccant material which draws water.
Dimensions and weight
The weight and size of a desiccant dehumidifier ought to be determined by the level of humidity and the area to be covered. Portable models are usually compact and lightweight, which makes them easy to transport and install in confined spaces. Also, the weight and size of a unit can point to its type, its coverage area, and its water tank capacity. Desiccant dehumidifiers are usually lighter and smaller than compressor models since the compressor-based models usually feature extra mechanical components.
Get yourself acquainted with warranties offered by various companies and additional incentives. You can get all those details from verified buyers online as well as authoritative reviews like this one. Backed by a five-year manufacturer’s warranty, the model with the most extended warranty on our list is the Eva-dry E-333 Renewable Mini Dehumidifier.
