Key Features to Look for Crawl Space Dehumidifiers
When selecting a dehumidifier for your home or business crawl space, it’s crucial to take into account specific important characteristics. Having a grasp of these attributes will enable you to make an informed choice and pick a dehumidifier that meets your requirements.
1. Moisture Removal Capacity
Typically, this is quantified using units such as pints per day (PPD) or gallons per day (GPD). When deciding on the appropriate dehumidifier capacity for your crawl space, take into account its dimensions and level of humidity. Larger areas or those with elevated humidity levels will necessitate dehumidifiers with higher moisture extraction capacities.
2. Size and Coverage Area
The size of the dehumidifier and its coverage area are also important considerations. It’s crucial to select a dehumidifier that fits the size of your crawl space appropriately. Also, evaluate the dehumidifier’s coverage capacity to ensure it can efficiently extract moisture from the entire area.
3. Energy Efficiency
Energy efficiency is crucial, especially for those planning to run the dehumidifier non-stop. It’s best to choose models that have Energy Star certification, indicating they meet strict energy efficiency guidelines set by the Environmental Protection Agency (EPA). Selecting energy-efficient dehumidifiers helps reduce energy costs and ensures effective moisture removal from your crawl space.

5. Continuous Draining Option
Choosing a dehumidifier with a continuous draining feature simplifies upkeep by removing the need for manual emptying of the water tank. This option allows for direct drainage into a nearby floor drain or sump pump, making operation more convenient.
6. Durability and Warranty
It’s crucial to evaluate the longevity of the dehumidifier and consider the warranty offered by the manufacturer. Give preference to models made from high-quality materials known for their durability. Additionally, choose units with a longer warranty period to ensure confidence and protection against potential issues.
