What are the Different Types of Dehumidifier?
Do you have a moisture problem in your basement? what about dampness creeping up the walls of your house? Do you have visible mold or mildew growing? Then the likely problem is moisture or excessive humidity, which can be coming from the basement or mid level crawl space in your house or office building. There are different types of dehumidifier to solve the problem.
This can be a sign of potential structural problems and might need to be checked out. In the meantime, the quickest and easiest way to reduce the moisture level in the air is to check out the different types of dehumidifier.
Once you have identified a need to dehumidify your basement, there are several choices to make between the different types of dehumidifiers on the market. Let us try to explain some of the differences between the types of dehumidifiers, to help you decide the best option for you.
Different types of dehumidifier
- Desiccant dehumidifiers: These are generally small dehumidifiers that utilize a chemical desiccant. This is designed to attract moisture from the air and traps it within the chemical. Generally a powdered chemical, these desiccant dehumidifiers have to be replaced when saturated with moisture. This is because the desiccant can not remove any further airborne moisture.
Peltier cycle dehumidifiers:
- Peltier cycle machines: Peltier cycle dehumidifiers remove moisture from the atmosphere using an innovative engineering method. The Peltier cycle allows the dehumidifier to run with a much higher efficiency. They operate by condensing water vapor without the need for a noisy pump and compressor. Dehumidifiers that run the Peltier cycle are much quieter and smaller than other types of dehumidifiers. They are smaller, quieter and cheaper to run.
Compressor driven dehumidifiers:
- Compressor driven dehumidifiers: The traditional method of removing moisture from the air involves compression of either the air, or some other refrigerant fluid. In effect, this process replicates the normal refrigeration process. Although it is a little more expensive than the options above, it can be used to remove large amounts of moisture from large rooms as quickly as possible.
Which is the best type of dehumidifier?
Types of Dehumidifier for Small damp spaces
If you have a small space with a damp problem, then you may be able to solve the issue of mold or mildew with a small and convenient desiccant dehumidifier. For example, if you need to dry out a small crawl space between floors, then a desiccant based dryer may be the answer. If you have a damp space or closet which is difficult to access. Or if your space does not have access to power, then the cheapest and easiest way is to place a desiccant dryer. The desiccant will have to be changed periodically. But this may be okay if the moisture problem is seasonal and not enduring.
If there is a power source in the crawl space, then a small peltier cycle dehumidifier may be the answer to the problem. For example, the “Ivation Mini” is small enough to fit inside a small crawl space. It is quiet enough to not bother those outside of the crawl space.
The Ivation Mini is a small capacity dehumidifier which is well suited to reduce humidity levels in enclosed spaces. The water storage tank is only 22 ounces, and has to be manually emptied. Fortunately, the Ivation Mini uses smart technology to shut off when the tank is full. The Ivation Mini dehumidifier runs on the Peltier cycle, so it is small, quiet and very efficient to run. It does not have a humidistat, so you have to manually switch it off if the humidity problem is seasonal.
Types of Dehumidifier for Medium sized basements
Eva-Dry Petite dehumidifier
If you need to keep a medium sized basement free of mold and mildew. Then the best way is to use a mid-range dehumidifier. A Peltier cycle dehumidifier may be the quietest and most efficient way to solve the problem.
For example, the “Eva-Dry” Electric Petite Dehumidifier is an ideal device for small to medium rooms such as bathrooms, laundries or basements. The Eva-Dry Petite dehumidifier uses a very miserly 23 Watts of electricity, so you can set and forget. It does have a limited size tank, with a shut off feature. So you will need to remember to empty the tank every so often.
Perfect to take on the road in your van or RV! The Eva-Dry Petite dehumidifier is a very handy device that you can use anywhere around your house or mobile home!
Ivation Intelligent Dehumidifier
Ivation also produce a mid-range dehumidifier which is a thermo-electric intelligent device suited for small to medium size basements basements, or perhaps bathrooms with a very high humidity level. The Ivation Intelligent Dehumidifier employs the Peltier cycle for energy efficient and quiet operation. This device can operate more than 2000 cubic ft basements with no trouble, but only has a 2 liter storage tank.
Fortunately the machine has an automatic shut off. But you will still need to empty the tank on a periodic basis to keep the moisture levels down. Not only does the Ivation have an intelligent overflow shut off, but it also comes with a humidistat. This device turns off the unit when the humidity level drops below the required level. This is an intelligent design which improves the energy efficiency of the unit and makes it one of the cheapest types of dehumidifier to run.
Types of Dehumidifier for Large Basements
There is no doubt that when you need to remove a large amount of humidity from the atmosphere of a large sized basement or damp room, then the most suitable option is to use a large capacity dehumidifier with electric powered compressor.
Keystone Energy Star Dehumidifier
One suitable option for large damp spaces is the Keystone Energy Star Dehumidifier. This is one of the best types of dehumidifier designed to remove large amounts of moisture from your house. The Keystone dehumidifier comes with either a 70 pint water storage tank, or can be plumbed directly to a drainage system for continuous operations. The Keystone dehumidifier can be programmed with different humidity settings depending on the seasonal differences. This powerful dehumidifier will actually reduce the humidity from your whole house. And you may experience the benefits of reduced humidity in more than just the basement where the machine is.
Frigidaire Energy Star Dehumidifier
Another excellent option for removing moisture from your basement is the Frigidaire Energy Star Dehumidifier. Frigidaire makes a wide range of refrigeration equipment. They are specialists when it comes to compressors, pumps and motors. The Frigidaire Energy Star Dehumidifier is designed to reduce the humidity and remove large amounts of moisture from the atmosphere. The problem on days of high humidity is that there can be a high flow rate of water condensed from the air. But the Frigidaire Energy Star Dehumidifier has both a large capacity storage tank, and can be plumbed directly to a drain where possible.
The Frigidaire Energy Star Dehumidifier is one of the best dehumidifiers on the market. Although it is a compressor driven system, it is a little noisier than a Peltier cycle machine. Still, if you leave it running in your basement, it will provide a fast and efficient way to reduce the humidity in your whole house. This helps make your house more comfortable for you, and reduces the growth of mold, mildew and other creepy crawlies.
