Air dehumidifier buying guide
After witnessing firsthand just how hostile and destructive excessive humidity can be, most people can’t help but appreciate the need for a decent dehumidifier. Fortunately, the market has a lot to offer in terms of features and functionality.
If you have just begun your search for the ideal air dehumidifier, you no doubt have more questions than answers at this point. This comprehensive air dehumidifier buying guide aims at equipping you with all the information you need to choose the ideal moisture sucking machine.
Things to consider when buying a dehumidifier
1. Size and extraction rate
Dehumidifiers come in a broad range of different shapes and sizes. The larger and more powerful a dehumidifier is, the more atmospheric water it can collect on a daily basis. If your home or office is either small or located in areas where dampness is not much of an issue, then smaller capacity dehumidifiers with around 7 litres a day extraction rate will do fine.
However, experts advise that no matter how much or how little space you have in your home, always try to buy the largest dehumidifier that your budget will allow. Going for units with over 20 litres a day extraction rates ensures faster moisture removal and some exciting features.
2. Energy efficiency
Dehumidifiers are typically rated from A to G according to their energy efficiency. If your unit is rated A, this means that it is among the most energy efficient models currently available in the market. Subsequently, A rated dehumidifiers use substantially less electricity to run than G-rated models.
You can choose to go for any rating you want, but the more energy efficient the unit is, the lower your runic costs will be. But do keep in mind that even if your particular dehumidifier does not come with an energy star rating, it doesn’t mean that is bad for the electricity.
Sometimes, industrial and commercial manufacturers just don’t need to spend all that money going through the approval process just to find out what they already know.
3. Noise factor
This is one of the most important factors that one cannot afford to overlook when buying a dehumidifier; especially if you are planning on using it when people are around such as in the bedroom, office, living room or any other populated area.
No matter what type of dehumidifier you have, they all use a fan that tends to make some noise. However, it is that compressor that will determine just how tolerable the noise levels are. Some of them vibrate quite vigorously while others hum gently and almost inaudible.
Generally, you want to keep things as quiet as possible. However, if noise is not an issue for you (maybe you plan to install the unit is a basement), then you should have no problem choosing a dehumidifier.
4. Water disposal method
Pay close attention here shoppers, because this is the feature that will determine if you will be making endless trips to the sink or doing nothing at all. While the average dehumidifier will always come with a sizeable collection tank, the extraction rate per day will always outmatch the reservoir capacity.
For example, most dehumidifiers with an extraction rate of 20 litres a day have a collection tank sized anywhere between 2 to 8 litres. This means that if you live in a very damp area, you might need to empty the massive tank every few hours.
Alternatively, you could avoid all the hassle and go for a more permanent solution. This involves connecting a continuous drain hose and utilising the power of gravity to draining the water to a floor drain or even directly outside.
Main types of air dehumidifiers
Refrigerant or compressor dehumidifiers
These are the oldest types of dehumidifiers that operate in a similar fashion to tour fridge. A typical refrigerant unit features fans to draw in air and a metal cooling plate for condensation inside the unit. As damp and humid air is drawn in the dehumidifier, it hits the metal plate and cools, then drips down to the tank below.
After this, the air is then circulated in the room, repeating the cycle over and over until the humidity reaches desired and safer levels. These units have a limitation in that they only work well at room temperature.
Desiccant dehumidifiers, on the other hand, utilise a type of desiccant material to absorb all atmospheric water from the air. While powered, the unit draws moisture packed air inside and passes it through the desiccant material. The material absorbs the water vapour, after which a warm stream of air is used to release the moisture to the tank below. Desiccant dehumidifiers are not only much quieter than refrigerant, but they are also lighter and smaller too.
How to use an air dehumidifier
Immediately after purchasing your brand new dehumidifier, it is important to follow all instructions when setting it up. Some models require assembly while others are ready to go straight out of the box.
For the first run, it is recommended that you run the dehumidifier at the highest settings possible for a couple of hours. Not only will this test out the model’s capabilities, but it will also stabilise the room’s humidity to safer levels.
Allow the dehumidifier to run for a couple of cycles and the switch it to automatic function if it has one.
Also, remember to only use certain dehumidifiers in cooler weather. Once temperatures start to drop, most dehumidifiers tend to build up frost on the machine’s coil and damage it’s efficiency. Some models are specially made for much cooler areas like the UK.
One of the most common mistakes that people make is to place their dehumidifiers in tight corners and in contact with the wall. This should only apply if your unit has a top-mounted air discharge. If not, you need to make sure there is enough air circulating the unit.
The better the circulation, the more efficient the machine is. For more efficiency, position your dehumidifier in the most humid room with all doors and windows closed.
Remember, dust is a dehumidifier’s worst enemy. It can lead to clogged filters and reduced performance; make sure you avoid dust sources at all cost.
Cleaning and maintenance
Before carrying out any cleaning and maintenance, make sure your unit is unplugged and turned off. Start by removing and cleaning the water reservoir tank with mild dishwashing liquid and warm water. T
he tank is the most vulnerable part for bacteria build up, try to clean it at least twice a month or more where possible. The air filter should also be checked on once or twice a year to ensure it is in excellent working condition.
If it needs cleaning or repair, make sure you get around to that as soon as possible to continue enjoying a fresh, healthy and damp-free environment.
Frequently Asked Questions
Q: Why is my dehumidifier blowing hot air?
A: A dehumidifier works by drawing in air and running it across coils which cool and condense the moisture. This air is then heated and removed as exhaust back into the room. As such, all dehumidifiers naturally produce some level of heat.
This heat will radiate at a constant rate as the unit circulates the air to lower the humidity. If your dehumidifier also blows out cold air, then that’s an air conditioner. Both of these appliances work exactly in the same way; except air conditioners release the hot air outside circulating the cool air back in the room.
Q: What is the difference between a dehumidifier and an air conditioner?
A: In essence, an air conditioner is quite similar to a dehumidifier. They both use different mechanisms to achieve the same result. Depending on the appliance, both dehumidifiers and air conditioners circulate air through a refrigerant.
The major difference is where the heat is expelled. Air conditioners have a fan system that circulates cool air while dumping hot air through a dedicated exhaust system. Dehumidifiers on the other hand could care less about your overheated brain. They just dump the hot air back into the room, with substantially less moisture.
Q: How do you remove moisture from the air without a dehumidifier?
A: There are many ways to remove moisture from your home. However, they depend on the cause of humidity, your home’s features and of course, budget. An easy way to achieve this is by opening your windows. Good ventilation reduces condensation in the room. You can also add a fan to keep the air moving along. As long as the air outside is less humid that inside, then air movement is usually enough to manage the humidity.
Apart from air movement, you can also absorb the moisture. Use desiccants such as salt crystals, calcium chloride and others to absorb excess moisture. Another option is to dry he air by using space heaters, chimney fires or a woodstove. Warming the air reduces humidity levels by evaporating excess water in the atmosphere.
Q: Why is it important to change air filters on desiccant dehumidifier?
A: Dehumidifiers have air filters which remove dust and contaminants from the air before passing it through the coils. This helps protect the coils from damage, wear and tear. Overtime, the air filters collect a buildup of dust and debris. If left dirty, the filter will affect the efficiency of your unit and quality of air produced.
However, you still need to replace your air filters after a while. This especially applies to people who live in extremely humid or dusty areas. After long periods of use, bacteria and mold will breed on the filter even after cleaning it. Needless to say, this can become hazardous to you and your family’s health. Always replace your humidifiers air filters before they get to this point.
