How to Choose the Right Dehumidifier for your Basement/Crawl Space

It is important to consider the following in choosing the right dehumidifier for you.

Right capacity based on room size or crawl space size and condition

A choice between drainage by gravity or using a condensate pump

Other key components that contribute to the effectiveness of a dehumidifier

How to choose the right capacity dehumidifier?

Crawlspace and basement series Dehumidifiers

As soon you make up your mind and decide to buy a dehumidifier, start by looking at the space that needs to be dehumidified. This allows you to choose the right ALORAIR Crawlspace & basement series dehumidifiers.

It's important that you know which type of basement or crawl space dehumidifier you'll need, as there are far too many options for crawl space dehumidifiers and basement dehumidifiers. You'll need something that's big enough to keep your crawl space dry and your basement free from excess moisture issues.

A crawl space dehumidifier is designed for the market and is meant to help eliminate high humidity in challenging environments, especially the tight spaces like crawlspaces and the basement, where mildew and molds grow, resulting in musty odors and corrosion. Saving you and your family from dust mites and mold ever making it into your house.

The AHAM equipment has a water capacity of 55 -140pints/day. They give excellent results if the size of the room is between 2,300-8,000sq.ft. This crawl space dehumidifier has unique dual airflow and a horizontal configuration that makes the dehumidifier ideal for the basement and crawlspace.

At ALORAIR you can find ENERGY STAR qualified and efficient dehumidifiers (The HD90 and HDi90, to be specific). They work well and will continue to remove water and moisture from the air even when the temperatures are low. However, you can use other models, and they'd work fairly well too!

How to Match the Capacity and Space Area

To effectively meet capacities, including dehumidifying the basement and the Crawlspace by getting away from excess moisture, The ALORAIR dehumidifier has moisture removal capacities that range from 55- 140 pints/day (AHAM).

So it is necessary that you know how you can choose the right dehumidifier. To be able to do this, you need to measure the size of the space you need to dehumidify and match it with the machine’s capacity.

At ALORAIR, we have a simple chart that can help you find the right capacity to work for you based on the space square footage and the space conditions.

So, use this chart which makes it easier for you to choose the right size for the dehumidifier. But first, you should know whether the crawl space is damp, very damp, or moderately damp.

Note that the moisture content level of the crawl spaces will depend on many factors, including the number of people that live in the space to be dehumidified, the activities they engage in, and their routine.

Notice that the more people who live in a particular space, the more respiration and the more moisture. Houses with low height are susceptible to condensation leading to dampness and might be unable to stay dry on their own. However, most crawl space dehumidifiers can get the job done here fairly easily.

After analyzing the space environment, you can then match the environment and the space square footage of your house. You need the best crawl space dehumidifier that works for your home!

You will then need to have a look at dehumidifier capacity data which gives the capacity and the area it should be used to dehumidify. Large spaces will need a commercial dehumidifier to effectively control moisture levels. On the other hand, for small spaces, a compact size will work well too, and it'll keep the noise level down!

How many pints capacity should your dehumidifier have?

If your space has 50-75% humidity levels that you want to remove, go for a dehumidifier that has at least 20-30 pints per day capacity. It should be able to last the day without much of an issue.

For spaces slightly more humid, 75-90% humidity, you'll need a commercial dehumidifier 25-40 pints per day. Aim for 40, but you can get away with a slightly lower number too.

In rooms that are "wet" (there's a leakage or standing water is present in the room) with humidity levels at 90-100%, you'll need something more powerful so look in the capacity range of 30-50 pints, as close to 50 pints as possible and the crawl space dehumidifier will be able to get rid of most of the humidity from the room!

Observe the Room's Condition

The right capacity of a dehumidifier will greatly depend on a room’s size in sq ft and condition. A small room does not always call for a low-capacity dehumidifier: such is also true for bigger rooms. Otherwise, the humidity levels might get out of control, and mold growth might just take over the whole unit.

You need to take note of every element or activity present in your space to be able to choose between the best crawl space dehumidifiers. For instance, if small living space is occupied by many people doing lots of simultaneous activities, then you will need a large-capacity dehumidifier to effectively dry the area.

As an example, our Sentinel HDi90 does the job with its 14.7ft. hose, giving you the ability to effectively drain away from your home.

Drainage by Gravity or Condensate Pump

Depending on your desired setup, you may choose a dehumidifier that is either gravity-drained or powered by a condensate pump. So it can adequately control excess moisture and improve air quality while being energy efficient!

Gravity-Drained System

This is most effective when your dehumidifier is elevated, as it will allow adequate drainage downwards through the hose.

Condensate Pump

This allows upward drainage of water that can be disposed of away from your enclosed space. Whether that's basements or crawl space. Some pumps show serious issues with overheating and rusting. Luckily, at AlorAir, our team of experts has developed a pump that withstands any compelling issues of other brands.
