The word mold strikes fear in the heart of every homeowner. Mold is unsightly. If allowed to spread, it can wreak significant, costly damage. Some types of mold even pose health risks, especially for people who have asthma or an immune system disorder.
What Cause Indoor Mold Growth?
An excessive amount of moisture is responsible for indoor mold growth. This moisture may originate from an aging roof, leaky plumbing, a damp basement, HVAC condensation, drafty windows or high humidity. Warmth and food sources like wood, paper, and fabric are facilitators of mold growth.

Buyer’s Guide
When you choose to purchase a dehumidifier, you also choose to make an investment in your home and your health. Before you guy, take a look at the features you absolutely need and the ones that are simply handy conveniences.
Necessary Dehumidifier Features
The size of the space that needs dehumidification should be the main detail you focus on when searching for a dehumidifier. You’ll need one that is rated to cover the square footage or cubic feet of the room. Usually, the more moisture a dehumidifier can extract, the bigger space it can cover.
Motor burnout and tank spills are two problems you want to avoid. Therefore, look for a dehumidifier that has automatic safety functions such as a shutoff and a defrost mechanism. Features like a full-tank indicator can help prevent an overfilled reservoir.
Lugging a tank filled with water can be an arduous task. To make trips to the sink easier, pick a model with a tank that has a handle. Reservoirs that easily slide in and out and have a secure lid can keep water from sloshing onto the floor.
If you need a heavy-duty dehumidifier, you don’t want to struggle under its weight. Large dehumidifiers should have wheels so that you can push instead of lift. They should also have handles to help you keep the dehumidifier steady during transport.
Handy Conveniences
A continuous drain lies in a gray area when it comes to an extra versus a necessary feature. Even though you can get by without a continuous drain, doing so with a big dehumidifier may be difficult for some people.
If you want precise control over the relative humidity, a humidity-equipped dehumidifier is a way to go. If you simply want to keep track of the humidity level, you can use a super-cheap hygrometer and buy a more basic dehumidifier.

Some models offer more than one fan speed. A dehumidifier with a variable-speed fan is helpful if you have a situation where quick moisture removal is needed, such as during the dry-out phase of a flooded basement. Otherwise, a dehumidifier with one fan speed is fine.
Finally, there is the timer. Sure, a timer is always great to have on an appliance. However, if mold growth is a concern, you’ll most likely need to run your dehumidifier around the clock, which makes a timer an extra, not a necessity.
FAQ
What Is a Cheap Way to Prevent Mold Growth?
Slapping on a new roof or gutting a home’s plumbing system can cost 10s of thousands of dollars. The average homeowner doesn’t have that kind of money lying around. Replacing a roof or a plumbing system doesn’t address the issue of high humidity.
However, a dehumidifier is an easy solution to reducing indoor humidity, and it’s a budget-friendly solution too.
How Does a Dehumidifier Work?
The sole purpose of a dehumidifier is to exchange moist air for dry air to reduce indoor humidity. To make this happen, a dehumidifier draws in the room’s moist air with a fan. Once inside of the dehumidifier, the air passes over an evaporator and a condenser, which cool the air and extract its moisture.
All the moisture collected by the dehumidifier drops into a collection tank, and the dry air is pushed back into the room. After a short span of time, the humidity level in the room decreases. When the tank is full, you remove it, dump the water and reinsert the tank.
Do I Have to Dump the Water Myself?
Not necessarily. Many dehumidifiers are equipped with a pump. You can connect a tube or hose to these humidifiers and thread it out of a window or attach it to a drain or sink. As the dehumidifier collects moisture from the air, that moisture is directed through the hose and released, so you don’t have to lift the tank and empty its contents.
Dehumidifiers without a continuous drain are often small with an easy-to-lift tank.
What’s the Ideal Relative Humidity?
To prevent mold, the relative humidity to strive for should range from 30 to 50 percent. However, it’s acceptable to keep your home’s relative humidity below 60 percent. Humidity levels above 60 percent can spark mold growth. Conversely, humidity levels below 30 percent may lead to dry sinuses and an increased likelihood of catching a cold or the flu.
How Can I Tell If My Home Is Humid?
Certain signs point to high humidity, and they are easy to spot. A musty smell in the air is one telltale sign. Discolored areas on the wall or ceiling are other indicators. Excess moisture may also cause paint to crack or wood surfaces to bubble.
If you’ve noticed signs of high humidity, you can get an exact relative humidity readout with a hygrometer. A hygrometer measures a room’s moisture level, and it shows the percentage on a needle dial or a digital display.
Do I Have to Use a Hygrometer to Monitor My Dehumidifier?
Only if you want to use one. Many dehumidifiers have a humidistat or a built-in hygrometer. While the inclusion of a humidistat was once reserved for pricey dehumidifiers, this technology is available on numerous affordable models.
A dehumidifier with a humidistat can monitor the relative humidity and be programmed to reach and maintain a specified humidity level. If you choose a model without one, you can still tell if it’s working by keeping an eye out for the signs of high humidity.
What Do Manufacturers Mean by Pints Per Day?
In a dehumidifier’s product description, you’ll see a number described as pints per day. This number tells you how much moisture the dehumidifier can remove from the air in 24 hours. Before a manufacturer can determine the number of pints per day, it must first test the dehumidifier.
This test is usually conducted in a room with a relative humidity of 60 percent and a temperature of 80 degrees Fahrenheit.
Can I Use a Dehumidifier When It’s Cold?
Whether or not you can use a dehumidifier in cooler indoor temperatures depends on the temperature itself. A typical dehumidifier is designed to shut off when the room gets colder than 65 degrees; some operate at lower temperatures.
Shutting itself down prevents ice from accumulating on the evaporator coils, which can cause the dehumidifier’s fan and compressor to malfunction. Most dehumidifiers have a fail-safe defrost cycle that kicks into gear, melting the ice before the ice causes a problem.
