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 basing on room size and condition
  • Choice between drainage by gravity or using a condensate pump
  • Other key components that contributes 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. This equipment are designed for the market and are meant to help eliminate high humidity in environments that look challenging especially the crawlspace and the basement where mildew and molds grow resulting in musty odors and corrosion. The AHAM equipment have a water capacity of 55 -140pints/day. They give excellent results if the size of the room is between 2,300-8,000sq.ft. They have a unique dual airflow and a horizontal configuration that makes the dehumidifier ideal for basement and crawlspace. Every dehumidifier you buy from ALORAIR are ENERGY STAR qualified and efficient. They work well and will continue to remove water even when the temperatures are low.

How You Can Match the Capacity and the Space Area

To effectively meet capacities including dehumidifying the basement and the Crawlspace, The ALORAIR dehumidifier have 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 look at 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 that can work for you based on the space square footage and the space conditions. So, use this chart which makes it easier for you choose the right size of the dehumidifier. But first, you should know whether space is damp, very damp or moderately damp. Note that the moisture content level 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 the people who live in a particular space, the more the respiration and the more the moisture. Houses that have low height are susceptible to condensation leading to dampness. After analyzing the space environment, you can then match the environment and the space square footage of your house. You will then need to have a look at a dehumidifier capacity data which gives the capacity and the area it should be used to dehumidify.

Observe the Room Condition

The right capacity of a dehumidifier will greatly depend on a room’s size and condition. A small room does not always call for a low-capacity dehumidifier: such is also true for bigger rooms. You need to take note of every element or activity present in your space. For instance, if a 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.

Drainage by Gravity or Condensate Pump

Depending on your desired set-up, you may choose a dehumidifier that is either gravity-drained or powered by a condensate pump.

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 away from your enclosed space. Some pumps show serious issues on overheating and rusting. Luckily, at AlorAir, our team of experts have developed a pump that withstands any compelling issues of other brands.

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.

Choose What is Right for You

You can see how the option of either draining by gravity or by a condensate pump serves absolute effectivity.
