What You Need to Know Before Buying a Dehumidifier For Your Home
Our experts have conducted a range of dehumidifier reviews for your consumption. Ask yourself the following questions when determining which dehumidifier is best for you:
Do I need a dehumidifier in my home?
Before you swipe your credit card, be certain that you need a dehumidifier. If you’ve got unfinished rooms (with dirt floors or incomplete insulation), consider finishing the project before investing in a unit. In situations like these, the dehumidifier will continue to pull moisture from outside, meaning that the unit will never be able to fully filter the air, and will be costing money to run inefficiently.
However, if you’re experiencing condensation build-up on walls or windows, peeling wallpaper and paint, or mold and mildew on floors and ceilings, it’s time to invest in a dehumidifier. Without one, you run the risk of structural damage or major health risks in your home.
Dehumidifiers can be used in any room in your home, including bathrooms, bedrooms, and laundry rooms. You can also find some models suited for cars, RVs, or boats.
How does a dehumidifier work?
Dehumidifiers are generally portable appliances used pull moisture from the air, filters it into a bucket or drainage system, and pushes dry air back out into the room. You’ll have to empty the water reservoir regularly if you don’t have a dehumidifier with continuous drainage or a built in pump.
What should I look for in a dehumidifier?
Other than size, shape, and portability, there are a few key aspects to consider when buying a dehumidifier: efficiency, capacity, automation, and power.
Efficiency can be defined as how much moisture your unit pulls from the environment. This is measured in ounces or pints per day (depending on the size of your unit), and the more your unit can pull, the less humid your space will be.
A unit’s capacity refers to the amount of moisture that your dehumidifier can hold before you’ll need to empty the reservoir. Many units come with a removable bucket or basin, which you’d need to empty in a sink or drain when it fills. Other units come equipped with pumping systems for disposing of the water continuously, as long as the unit is placed near a drain or sink.
More advanced dehumidifiers come packed with automation features to make your life easier, including automatic shut-off when your water reservoir is full, automatic defrost to prevent the freezing of your unit in colder climates, automatic restart that activates after power outages, and automatic humidity sensors to avoid making a room too dry.
In this era of high utility bills and households “going green,” you may also want to consider an energy-efficient model. If you live in a climate prone to humid summers or damp winters, your dehumidifier could be running for days on end. While this may keep the air dry, it will suck up a lot of energy, which you’ll see on your next electric bill. Some eco-friendly units use 15% less energy than others, while doing a comparable job.
So if cost and efficiency have been covered, we need to consider perhaps the most important reviews of them all, safety. When considering which dehumidifier has the best reviews for safety and overall value, we are in a good position to expect that compliance, particularly with the reputable sellers (like Amazon, Homedepot) require a safety certificate or the units they carry are specifically compliant with the safety regulations. They are often required to undertake safety reviews of the dehumidifiers that they stock. There are some things you may want to consider though in order to help prevent any safety concerns once you have your dehumidifier back in the home:
- Read the user manual and follow manufacturer’s instructions. Familiarise yourself with the unique features and requirements of your dehumidifier (and read any reviews that may have been posted online)
- Set up your dehumidifier properly. Make sure your unit is placed on a level surface, clear of other objects and that there are no obstructions to its air intake. Blocked air intakes can cause dehumidifiers to overheat and lead to increased fire hazard risk.
- Inspect power cords and replace when necessary. Thoroughly check all cables and cords to ensure that there are no exposed wires or worn cords. This is common in places where the cords/wires bend around corners or rub against any other objects. Never use a dehumidifier with a damaged power cord, as this could pose an electrical shock hazard or a fire risk. Remember to read the review booklet enclosed with your unit
- Regularly clean or replace any filters following manufacturers instructions.
- Check the air filter to ensure that is not clogged or damaged. If there are any signs of damage replace it immediately.
If you are unsure about the safety of your dehumidifier have it checked by a registered electrical worker, preferably someone who is familiar with the fault reviews of the model you are considering purchasing.
