Which one should you choose?
Choose AlorAir 120-Pint Crawl Space Dehumidifier with Pump if
- You need to dehumidify a space larger than 1,200 square feet
- You require vertical water discharge via a built-in pump for difficult drainage setups
- You prefer a white finish for your equipment

- You prefer a blue finish for your equipment
Verdict: Choose the 120-pint model if you need maximum capacity and the flexibility of a built-in pump for upward water discharge. Pick the 113-pint model if your space is smaller and you do not require vertical pumping capabilities. Both units offer robust construction and reliable automatic defrost for year-round use.
120-Pint vs 113-Pint Crawl Space Dehumidifier
Moisture removal capacity
The AlorAir 120-Pint Crawl Space Dehumidifier with Pump (Helios MP55) leads in raw performance. It removes up to 120 pints per day under saturated conditions, compared to 113 pints for the AlorAir 113-Pint Crawl Space Dehumidifier (Sentinel HD55). Under AHAM standards, the Helios MP55 handles 55 pints daily, while the Sentinel HD55 manages 53 pints. This difference matters in very wet environments. The extra capacity helps the Helios MP55 keep up with higher humidity loads. If you deal with severe dampness, the higher rating provides a margin of safety. The Sentinel HD55 is still powerful, but the Helios MP55 offers more extraction power for demanding spaces.
Coverage area
Coverage area differs between the two models. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump covers up to 1,500 square feet. The AlorAir 113-Pint Crawl Space Dehumidifier covers up to 1,200 square feet. This 300-square-foot gap is significant for large basements or expansive crawl spaces. The Helios MP55 is better suited for larger areas. If your space is under 1,200 square feet, both units will likely perform adequately. However, for larger zones, the Helios MP55 ensures consistent humidity control across the entire footprint. The Sentinel HD55 is ideal for smaller, confined areas where its 1,200-square-foot limit is sufficient.
Drainage system
Drainage methods vary between these models. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump includes a built-in pump. This allows water to be discharged vertically up to 19.6 feet. This feature is crucial for crawl spaces where gravity drainage is not possible. The AlorAir 113-Pint Crawl Space Dehumidifier uses automatic drainage without a tank but does not list a built-in pump. It relies on gravity drain hoses. If you need to pump water upward through a window or sink, the Helios MP55 is the clear choice. For areas with floor drains nearby, the Sentinel HD55 works well with gravity drainage. The pump adds flexibility for complex installations.
Dimensions and weight
Physical dimensions differ slightly. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump measures 12.6 inches in width, 14.2 inches in height, and 17.9 inches in length. The AlorAir 113-Pint Crawl Space Dehumidifier measures 12.2 inches in width, 13.3 inches in height, and 19.2 inches in length. Both units weigh 41.7 pounds. The Helios MP55 is taller but narrower, while the Sentinel HD55 is shorter but wider. Weight is identical, so portability is similar. The height difference may matter if you have low clearance in a crawl space. The width difference affects how much floor space each unit occupies. Choose based on your specific spatial constraints.
Control features
Control options are a key differentiator. The AlorAir 120-Pint Crawl Space Dehumidifier with Pump features smart set-and-forget operation. It includes automatic defrost, GPP mode, and pump mode. It also retains settings after power outages. The AlorAir 113-Pint Crawl Space Dehumidifier offers automatic defrost and simple humidity adjustment. It has an optional remote control system, but the Helios MP55 integrates pump control natively. The Sentinel HD55 lacks a listed built-in pump, so it cannot manage vertical drainage automatically. The Helios MP55 offers more integrated automation for unattended operation. If you want seamless pump management, the Helios MP55 is superior. The Sentinel HD55 requires manual oversight for pump-dependent setups.
Which Alorair Model Fits Your Crawl Space
Users needing vertical drainage flexibility
The Helios MP55 includes a built-in pump that discharges water vertically up to 19.6 feet. This feature allows you to route drainage through windows or sinks without relying on gravity. If your crawl space layout prevents downward flow to a floor drain, this integrated pump provides the necessary installation flexibility for continuous operation.
Those covering larger square footage
This model covers up to 1,500 square feet and removes 120 pints per day under saturated conditions. If you have a larger crawl space or basement, the higher capacity handles greater moisture loads more effectively. The extended coverage area ensures the unit can maintain balanced humidity levels across a wider footprint without struggling.
Buyers wanting a standard compact unit
The Sentinel HD55 offers a rugged metal casing and automatic drainage without a tank. It covers up to 1,200 square feet and removes 113 pints daily. This model suits smaller spaces where a built-in pump is unnecessary. Its compact design and optional remote control make it a practical choice for standard crawl space applications.
