How Do Humidifiers Improve Air Quality?

Dehumidifiers work as their namesake suggests. Essentially, they remove excessive moisture from the air. This moisture isn’t visible, but it sure is felt. Humid air can feel sticky and uncomfortable, making it difficult to spend any real time down there. In most cases, it’s instantly felt the second you come down the stairs. What’s worse is the results of extra moisture.

Mold can start to grow in any area where the humidity level is 60 percent or more. Mold can wreak havoc on the overall structure of your basement and anything in it. If you store any precious items down there, they’re at risk for damage over time. Damage is especially bad on wooden or porous objects. Mold will grow on carpets, clothes, and even drywall.

improve air qualityDehumidifiers help avoid these issues by bringing down the humidity level significantly. A fan pulls air into the device. This air is then stripped of its moisture thanks to its exposure to hot and cold temperatures.

Inside the dehumidifier are two sets of coils. These coils are filled with refrigerant to make them hot and cold. As the air enters the device, it first makes contact with the cold coil. When this happens, the moisture is pulled from the air and falls down to a reservoir.

The air then goes through the hot coil to warm it back up to room temperature before being recirculated into the room. With their powerful fans, dehumidifiers also keep the air moving to avoid stagnation.

How to Choose the Right Dehumidifier for Your Basement

There’s a wide range of options available. However, the right one for your space depends entirely on a number of factors. Not all dehumidifiers are the same, so it’s important to know what to look for and how to choose based on your needs.

Portability and Features

Manufacturers offer dehumidifiers in a variety of different sizes. Generally, the machines are quite large. It’s good to consider the portability of a dehumidifier to ensure that it doesn’t become cumbersome in the space. Many options come with castor wheels that make moving it a cinch. This ensures that you can easily move and empty the device as needed.

In addition to portability, take a look at some additional features you may need. Do you plan on running the machine all day long or only when you’re in the room? If you plan on running it constantly, it’s recommended to get an option with an automatic shutoff to ensure that the reservoir doesn’t overflow.

Timers and sensors can also be beneficial if your looking for something low maintenance. Additional features like hoses for emptying the reservoir and automatic functions should be considered as well.

Square Footage and Humidity Level

Before purchasing a dehumidifier, you need to consider the size of your basement and how damp the air feels. Larger spaces will need a robust system that can quickly remove moisture. You want to get a system that matches the needs of your space. A small dehumidifier won’t do much for a large room. Large systems are typically capable of removing 75 pints or more of moisture per day. Medium and small systems can remove between 45-50 pints and 25-40 pints per day respectively.

ideal humidity levelWith that being said, it’s also good to consider how much moisture there is and how much you want to run the machine.

If your basement isn’t too bad, you may be fine with a medium machine. Alternatively, a smaller space with significant moisture may need a larger option.

All in all, it’s about finding the balance you need. It’s a good idea to measure the moisture in your basement, measure its dimensions, and choose accordingly based on those parameters.

Energy Efficiency and Noise

Dehumidifiers run very similarly to that of your HVAC system, so running costs can be quite significant. Look out for energy efficient models to keep the costs down. Many newer models run on less power without sacrificing efficiency.

When it comes to noise, quieter is always better. Depending on where the dehumidifier is placed, it can produce up to 67 decibels of noise. Some manufacturers design their machines to be quieter so that it can be used around the clock. Pay attention to noise levels, especially if you’re in a smaller space.

Over to You

A dehumidifier can transform your basement from a drab and damp abyss into a comfortable space you don’t mind spending time in. These devices dramatically improve air quality by removing excess moisture and contaminants. Most people don’t even realize how much moisture the air was harboring until they see it in the reservoir.

With a high-quality unit, you can avoid potentially harmful mold and keep your basement and any of your belongings safe. Whether you’re using your basement as storage or as a relaxing man cave filled with cool gear, a dehumidifier will make the space that much better.
