70-Pint vs 155-Pint Crawl Space Comparison
Moisture removal capacity
The Moiswell 70-Pint Crawl Space Dehumidifier with Pump removes up to 70 pints of moisture per day at saturation. Under standard AHAM conditions, it extracts 35 pints daily. In contrast, the Moiswell 155-Pint Crawl Space Dehumidifier handles significantly heavier loads. It removes up to 155 pints per day at maximum capacity. Under AHAM conditions, it extracts 70 pints daily. This makes the 155-Pint model suitable for extremely damp spaces or larger areas where the 70-Pint unit might struggle to keep up with high humidity levels.
Coverage area
You should consider the square footage you need to treat. The Moiswell 70-Pint Crawl Space Dehumidifier with Pump is designed to cover up to 1,000 square feet. This is ideal for smaller basements, bathrooms, or tight crawl spaces. The Moiswell 155-Pint Crawl Space Dehumidifier covers much larger areas. It can handle spaces up to 6,000 square feet. If you are dealing with a large basement or a commercial setting, the 155-Pint model provides the necessary power to dry the air effectively across that wider range.
Drainage method
Water removal is critical for continuous operation. The Moiswell 70-Pint Crawl Space Dehumidifier with Pump includes a built-in pump. This pump can push water vertically up to 16.4 feet. This feature eliminates the need for gravity drainage, allowing you to place the unit anywhere. The Moiswell 155-Pint Crawl Space Dehumidifier relies on a drain hose and auto drain function. It does not list a built-in pump. If you need to pump water upward to a drain line, the 70-Pint model offers a distinct advantage.
Physical dimensions
Fit matters in tight crawl spaces. The Moiswell 155-Pint Crawl Space Dehumidifier features a horizontal design measuring 22.5 inches in length, 14 inches in width, and 14.7 inches in height. This low profile allows it to fit between floor joists and in low-clearance areas. The Moiswell 70-Pint Crawl Space Dehumidifier with Pump is taller and narrower. It measures 13 inches in length, 15 inches in width, and 12 inches in height. While both are compact, the 155-Pint model’s horizontal shape is specifically engineered for installation under floor joists.
Airflow performance
Air circulation affects how quickly moisture is removed. The Moiswell 155-Pint Crawl Space Dehumidifier boasts an airflow rate of 265 CFM. This high volume of air helps rapidly dry extremely damp spaces. The data for the Moiswell 70-Pint Crawl Space Dehumidifier with Pump does not list a specific CFM rating. Without this specification, it is difficult to compare their air movement capabilities directly. However, the higher CFM of the 155-Pint model suggests faster drying times for large volumes of air.
Weight and portability
You may need to move these units for maintenance or placement. The Moiswell 70-Pint Crawl Space Dehumidifier with Pump weighs 39.5 pounds. It features two handles for lifting, making it relatively lightweight and easy to reposition. The Moiswell 155-Pint Crawl Space Dehumidifier is heavier, weighing 63 pounds. While still manageable, the increased weight reflects its larger internal components and higher capacity. If you frequently move the dehumidifier, the lighter 70-Pint model is easier to handle.
Which Moiswell Dehumidifier Fits Your Space
Users needing easy water removal in smaller areas
The 70-Pint model includes a built-in pump that pushes water up to 16.4 feet vertically. This eliminates manual tank emptying, which is crucial if gravity drainage is not possible. It covers up to 1,000 square feet and weighs only 39.5 pounds, making it lightweight and simple to move into tight crawl spaces or basements.
Those with large or extremely damp spaces
The 155-Pint unit removes up to 155 pints daily at maximum capacity, handling large volumes of moisture efficiently. It is designed for spaces up to 6,000 square feet and features a horizontal shape measuring 22.5 inches long. This compact profile allows it to fit between floor joists in low-clearance crawl spaces where other units might not fit.
Buyers prioritizing airflow and auto-restart features
This model boasts a 265 CFM airflow rate, which helps dry damp areas more rapidly than lower-capacity units. It also includes an auto-restart function that resumes operation after a power outage. The auto drain feature works with a drain hose for continuous removal, ensuring you do not need to monitor water levels in hard-to-reach installations.
