Buying Guide For The Best Crawl Space Dehumidifier
While looking for the best crawl space dehumidifier, you’ll variably come to a standstill on having a look at the numerous options. And, it’s very easy to get yourself a device that would remain unused or would be unusable for your crawl space. Hence, through extensive research, we have collected some of the essential points to look for while getting a dehumidifier, especially for crawl spaces.
Size
One of the first things to remember while looking for a dehumidifier is that crawl spaces don’t usually have a lot of room. Hence, if you end up buying a big device, it may not fit in that area.
Before you even start looking for a dehumidifier, we suggest taking the height of the available space. To do this, take a tape measure and find the length between the floor until it touches the brick or wooden roof. That should be the maximum height of any device you want to fit in the crawl space.
Area Coverage
Similar to the previous point, another essential point to consider is the area coverage of a device. The area of a certain space is usually measured in square feet, and brands will explicitly mention the maximum area coverage for a space.
Ideally, you should always calculate the area of the crawl space of your house before ordering a dehumidifier. Even though it might seem like a bright idea to get one with a large area coverage, it may end up causing the air to get too dry. Hence, be careful about choosing the perfect area coverage, which would also decide the size of the overall device. On average, most dehumidifiers go up to 2,500-3,000 square feet.
Dehumidifying Capacity
What’s the use of a dehumidifier if it can’t get down the humidity levels of a crawl space? That’s why while looking for one, make sure to check its performance capability. Usually, most dehumidifiers will run for a cycle of 24 hours and get rid of the moisture from the air present in a space.
Brands often market the products with the drawing capacity by mentioning the pints of water drawn per day (PPD). When you’re buying a dehumidifier for a larger space, try to get a device with more capacity to draw the maximum amount of humidity. The average range is between 10-90 pints per day, but there is some huge unit with extra capacity.
Features
While looking for the best crawl space dehumidifiers, you should also check out the features included in the device. Without a proper device, a dehumidifier can give you a hard time when it comes to using it.
One of the foremost points is the ease of use. It’s best to get a device that comes with a clear digital display that shows the settings and the humidity level. Remote control or Wi-Fi capability is always an add-on as it lets you control the device from anywhere around your home.
Another important feature is the filter present in a dehumidifier. Some come with added benefits to clear out the air quality. However, the simplest thing to look for is how frequently the filter needs a change and if the method is easy.
