Dehumidifiers are essential tools for the home that people do not seem to talk about as much as other devices. They play a vital role in protecting and maintaining your home and your belongings by removing excess moisture.
This stops mold or dampness from building up and causing damage. Dehumidifiers can also help to protect your overall wellbeing, keeping your airways open and protecting your skin.
Even the best dehumidifiers have an expiration date, and it’s important to know how long a dehumidifier will last. This guide will help you understand how long a dehumidifier will last and what you can do to help protect it.
What Affects the Lifespan of a Dehumidifier?
Not all dehumidifiers are the same, but the longevity of a dehumidifier is massively impacted by how it’s used and how it’s treated. It’s essential to be aware of these so you can help to protect your device.
Frequency of Usage
Every dehumidifier is made knowing it will only work for a certain time, and it certainly won’t last forever. The most often you use it, the shorter the lifespan will be, so it’s important to consider when you actually need it.
Many people live in areas where you only need to use a dehumidifier at specific times of the year. It may be worth investing in a hygrometer so you can understand the humidity levels in your room, and you can then determine when you need to run it.
Duration of Usage
Dehumidifiers will take some time to work but shouldn’t necessarily be left on all day. In an average room, they shouldn’t need to be left on for more than 12-15 hours, and past this point, you risk over-drying the air. You’ll also fill the tank by this point unless you have a large dehumidifier.
By running it for too long, you are burning through the lifespan of the device and putting undue strain on it. It’s worth investing in a humidifier with a built-in moisture meter so it can switch off when your air has reached the desired levels.
Level of Maintenance
Cleaning and maintenance are vital for any piece of home equipment. Your humidifier needs to be emptied regularly to run but also needs to be cleaned every few weeks. This prevents any build-up of minerals or impurities which might have been in the moisture in the air.
You should carefully examine your dehumidifier every few months to check for any broken components or issues. This will help you identify issues early and save you from having to replace the whole device. Regular cleaning and maintenance can add years to the life of your dehumidifier.
Dehumidifiers tend to fail when they’re overused. Leaving them on for long stints isn’t just bad for the machine, but it’s bad for your home too because it can over dry the air. When left on for too long, it will cause the components within to overwork and break down.
Similarly, if you fail to look after your dehumidifier, then you won’t pick up on any damage, and the components will be under more strain. All of this will mean your dehumidifier needs replaced more often.
How Many Years Does a Dehumidifier Last?
A dehumidifier will typically last 5 to 10 years, and this will be heavily influenced by the make, model, and how you look after it. After this point, your dehumidifier will start to work less effectively, and you may start noticing issues occurring.
When you see the performance start to drop, you should start to consider replacing the device.
How To Tell If Your Dehumidifier Isn’t Working Effectively
Typically, it’s your compressor or your capacitor within a dehumidifier that breaks. The compressor is the pump that circulates the refrigerant and extracts moisture from the air.
If this stops working, then you’ll find the moisture levels in your room just aren’t decreasing, and the dehumidifier has stopped being effective. You might also notice the temperature in the room rising as the machine keeps working, but no humidity is removed.
The capacitor is the circuit board which allows the motor to run. When this is damaged, the machine may struggle to turn on and will trip more regularly. Your dehumidifier is a lot less effective if it doesn’t run for at least 8-10 hours, so when it starts to trip it becomes pretty useless.
Other signs that your dehumidifier isn’t working effectively can be that the tank isn’t filling with water or that it’s filling too often. Or it could be that it’s starting to leak. All of these are signs that there’s a serious issue.
Types Of Dehumidifiers & Their Lifespan
There are two main types of dehumidifiers available, and each of them has a slightly different lifespan. Here’s a quick breakdown:
Refrigerant dehumidifiers work in the same way as fridges to cool the air. Air is drawn into the device, then cooling coils cause the temperature to drop, and air condenses within the dehumidifier. Dry air is then released back into the room.
Refrigerant dehumidifiers are reliant on the coils within the unit, and if these stop working, it’s very ineffective. If you buy a good make and model, then this should last for 5 years or longer, but some cheaper models will only give you 1 good year. If you notice your dehumidifier becoming less effective, then you should check the coil first.
Desiccant dehumidifiers work using absorbent materials within the device. Air is drawn in and passed through a chamber with these absorbent materials where the moisture is literally drawn from the air. Typically, silica gel is used to absorb the water, and then the dry air is released back into your home.
Desiccant dehumidifiers have very few moving parts and therefore last a lot longer. These aren’t normally as effective as refrigerant dehumidifiers but should last well over 5 years.
How To Make Your Dehumidifier Last Longer
To protect your investment and help your dehumidifier last longer, there are a few things you should consider:
- The Brand
Buying from a reputable brand is always a good choice. These will typically have a higher build quality and last longer. Remember, you don’t need necessarily need to spend more money, you can still get good value for money with well-known brands.
- Correct Installation
Make sure you follow the manufacturer’s instructions closely and install it correctly. The good brands give very clear instructions on how and where to install your dehumidifier, so be sure to follow them to stop any avoidable issues coming up.
- Not Overworking It
Don’t run your dehumidifier too often or for too long. The truth is that your home probably doesn’t need it, and it puts a lot of strain on the mechanisms within the device. However, by only using it when you need to, you can help protect it for longer and extend its life by a few years—getting a device with a hygrometer built-in will help because it should shut off automatically when moisture levels reach a certain level.
- Regular Maintenance
Ensure you clean your dehumidifier regularly and remove the water so no contaminants can build up in the tank. Your filters will need to be replaced regularly because they can cause dirt and bacteria to build up in the device and spread into the air in your home. Try to carry out a full maintenance routine every few months.
- Protecting Against Surges
Your dehumidifier will be on for a long time. An anti-surge device will help protect the circuits within the device from any unexpected damage and lowers the risk of any fires in your home.
- Understanding The Warranty
The best way to protect your investment is to understand the warranty. Most manufacturers will give a guarantee for at least a few years, which will mean you get a replacement device if it breaks unexpectedly.
People Also Ask (FAQ)
Are there any dehumidifiers that last a lifetime?
Most dehumidifiers will last 5 to 10 years and only have a warranty for a few years. A few brands, like Goldenrod, offer a lifetime guarantee on their products, but this isn’t common.
Should a dehumidifier run constantly?
No, your dehumidifier shouldn’t really need to run constantly, as this can put a strain on the device and make your air too dry. You should only look to run your dehumidifier for 12-15 hours per day maximum.
Dehumidifiers are a great way to help regulate the moisture in your home and protect everything in it. A good dehumidifier should last you 5 to 10 years, but to get the most from it, you need to put the effort in. Putting the time in to clean and maintain your device will help you to protect the investment and keep it working effectively for longer.
