Choosing the Right 70-Pint Dehumidifier
Check for Built-In Pumps
Select a unit with a built-in pump if your space lacks a floor drain or gravity outlet. The Helios MP35 includes this feature, allowing water to move upward. This is essential for garages or deep crawl spaces where gravity drainage is impossible. Without a pump, you must place the unit near a drain or empty the tank manually. The Sentinel HD35P also features a pump, offering flexibility for vertical drainage needs in tight areas.
Verify Wi-Fi Connectivity
Choose Wi-Fi enabled models if you need remote monitoring from your phone. The Sentinel HD35P offers full app control, letting you adjust settings without entering the crawl space. This is useful for tracking humidity levels in inaccessible areas. Other models on the list do not mention smart connectivity. If you prefer manual control, you can skip this feature. However, remote access provides peace of mind for monitoring moisture trends over time.
Prioritize Auto Defrost
Ensure the unit has auto defrost if you live in a cold climate. This feature prevents ice buildup on the coils during low temperatures. The Sentinel HD35P, Sentinel HS35, and Helios D35 all include auto defrost. This allows reliable operation in unheated basements or crawl spaces. The Helios MP35 does not list this feature, so check its cold-weather performance separately. Auto defrost maintains efficiency when ambient temperatures drop below freezing.
Consider Unit Weight
Check the weight if you need to move the unit frequently. The Helios D35 is the lightest at 25.1 pounds, making it easier to carry. The Sentinel HS35 weighs 37.8 pounds, and the Sentinel HD35P weighs 38.2 pounds. Heavier units may be more stable but harder to relocate. If you store the dehumidifier seasonally, lighter models reduce physical strain. The Helios MP35 weight is not listed, so assume it may be heavier.
Match Drainage Methods
Align the drainage method with your space layout. Most models use a drain hose for gravity flow. The Sentinel HD35P, Sentinel HS35, and Helios D35 rely on this standard method. The Helios MP35 uses a built-in pump for vertical movement. Choose gravity drainage if you have a nearby floor drain. Select pump drainage if the drain is above the unit. This decision impacts installation complexity and ongoing maintenance requirements.
