8 Reasons You May Need a Dehumidifier

A dehumidifier is designed to reduce the humidity levels in the air, creating a more comfortable and healthier environment for you and your family to live in. These can be used in homes, offices or practically anywhere you want to reduce excess humidity levels

Dehumidifiers are available in different sizes to suit the extent of the problem and the size of the room you plan to use it in. While they’re not the most stylish of appliances you could have in your home, they could help to solve many of the most common problems that people face due to high humidity levels.

But the big question is: Do you actually need a dehumidifier for your home?

To answer your question, we’ve come up with a list of 8 most common reasons why you may need a dehumidifier, many of which you have probably experienced if your home has high levels of humidity. Let’s take a look at these common problems since they might help you to decide whether purchasing a dehumidifier is the right thing to do.

1. Your home smells musty

As much as we like to have our homes smelling fresh and clean all the time, the presence of mold and mildew can prevent this from happening. Mold tends to grow when condensation combines with other environmental elements and with moisture from humidity. As it grows and spreads, it emits certain gasses which are known as microbial volatile organic compounds (MVOCs). MVOCs are responsible for that ‘musty’ smell that’s hanging around your home and since they have a low odor threshold, their strong odor is easy to smell.

How a dehumidifier helps: A dehumidifier can help take away the unpleasant moldy scent by drying out the air and preventing the growth of mold and mildew. 

2. Water leaks in your basement are common

You may have experienced water dripping all over your basement floors, rings that look like mold spores on your walls and sweaty walls after heavy rain. This is a common problem that many people have.

How a dehumidifier helps:  You might want to get a dehumidifier to dry the area out and keep it dry continuously. For those with damp basements, it would be a good idea to keep the dehumidifier running all throughout summer to avoid any potential issues.

3. You want to air-dry laundry indoors

Not everyone has the option of hanging their clothes out to dry in the sun. If you haven’t got any garden space or balconies to dry out your clothes, you’ll probably have to do it indoors. When you hang your wet clothes indoors, moisture evaporates from them, leading to problems with mold and increasing condensation levels. A dehumidifier will be extremely helpful, especially in the winter months.   

How a dehumidifier helps: By having a dehumidifier set up in the room where you hang your clothes to dry, excess moisture will be removed, creating a more comfortable environment for your clothes to dry indoors without the risk of getting ill or promoting the growth of mold. While it may not be the fastest or most effective way of drying your clothes, it certainly can work and is easy to set up.

4. You or someone in your family has allergies or asthma

If you or a family member has allergies or asthma, the reason could be excess humidity in the air. Air that has far too much moisture is an excellent breeding ground for certain allergens like mold, mildew, bacteria and dust mites. These irritants can enter your home through the windows, doors and ventilation system. When there’s plenty of moisture in the air, they can easily and quickly multiply into whole colonies of allergens, taking only a few hours.

How a dehumidifier helps: A dehumidifier can be a great solution to this problem since it takes moisture out of the air and protects your home from mold growth or dust mites which are both responsible for triggering allergy symptoms. These appliances can also clear up allergy mucous secretions quickly, leaving you congestion-free. However, be careful not to allow the humidity in your home to drop below 35% since this can cause other allergy symptoms to flare up.

5. There’s condensation on your windows

Condensation is what happens when warm air hits a cold surface, or when there’s far too much humidity inside your home. When water vapor in the air deposits on a surface that’s at a much lower temperature, the result can be condensation on your windows. Moist air makes contact with the impermeable, cold surface and releases some of its moisture onto the glass of your windows as water droplets which is what we call condensation.

How a dehumidifier helps: Since it draws excess moisture from the air, a dehumidifier combats the problem of condensation, so you won’t have to worry about sweaty windows again.

6. Your food tends to go stale or moldy quickly

Mold Food

Water or moisture has an impact on the quality of food and spoilage can easily occur when there are changes in the humidity levels. Just like moisture condenses on your windows, it can do the same on the surface of your food.  Moldy grain, lumping of dry powders like spices and soggy cereals can be the result of excessive moisture. There are also some other issues like mottling, stickiness and crystallization which can be observed in certain foods. As moisture condenses on food, it provides a suitable environment for molds and bacteria to grow and multiply in large numbers, the result being that your food spoils faster than it should.

How a dehumidifier helps: Surprising as it may seem, running a dehumidifier in your home can make your food taste better for longer. A dry environment helps to keep food fresher longer.

7. There are bugs you want to get rid of

If you’ve noticed too many bugs around in your home, there’s a high chance that they’re there because of excessive moisture in the air. Yes, bugs do love to be hydrated just like everything else to survive. Some of the most common pests that are attracted to the moisture in your home include cockroaches, silverfish, centipedes and earwigs.

How a dehumidifier helps: To get them out of your home, you’re going to have to control humidity and eliminate all sources of moisture. Investing in a dehumidifier is a great solution for getting rid of these pesky insects since it will dry out the air, creating uncomfortable living conditions for them. Where there isn’t enough moisture in the air to keep these insects alive, they will either die or leave.

8. Your furniture is getting damaged

Although you may not realize it, humidity (either too little or too much) can be a serious threat to your beautiful wooden furniture. When wood furniture is exposed to high levels of humidity, the wood can begin to expand and deteriorate. It absorbs the excess moisture which causes it to swell or expand. If wooden furniture is exposed to high humidity levels for prolonged periods of time, they may never return to their original size.

How a dehumidifier helps: Since dehumidifiers are specially designed to keep humidity levels in check, it reduces the risk of your furniture becoming damaged slowly over time. 

The Takeaway

Excess humidity, as we’ve seen, can cause major issues in your home. While this may not be the only issue, in most cases, it’s a major cause. Investing in a dehumidifier comes with a range of benefits and can solve many problems in your home. Most users find that they’re worth the cost.
