Who it fits
Good fit for
You should choose this dehumidifier if you need serious moisture removal in large, challenging areas. The 120-pint capacity handles high humidity levels in crawl spaces, basements, and garages. The built-in pump is essential if you cannot rely on gravity drainage or need to push water upward through a window. The corrosion-resistant casing ensures reliability in dusty or damp commercial environments. If you want a set-and-forget solution with automatic defrost and power outage memory, this unit fits your needs.
Who should skip it
Skip this model if you need a compact unit for small rooms. The Helios MP55 is large, measuring 17.9 inches in length and weighing 41.7 pounds. It is designed for crawl spaces and commercial use, not standard bedrooms. If you require a remote control or hanging kit, you must purchase these accessories separately. The base model does not include washable filters or stable installation kits. You may find a smaller, lighter option better suited for residential living spaces or areas with lower humidity demands.
Verdict: The AlorAir Helios MP55 offers robust 120-pint performance and flexible pump drainage for large, humid spaces. It is a practical choice for crawl spaces and commercial areas requiring durable, automated humidity control.
Key specs for this dehumidifier
Moisture Removal Capacity: 120 PPD (55 PPD AHAM)
This unit removes up to 120 pints of water daily under saturated conditions, which is the standard for crawl spaces. The AHAM rating of 55 pints reflects performance in typical home environments. You should compare this high capacity with standard residential models that often max out at 50 pints. This spec ensures the device handles heavy moisture loads in damp, enclosed areas effectively.
Coverage Area: 1,500 sq ft
The manufacturer specifies that this dehumidifier can effectively control humidity in spaces up to 1,500 square feet. This makes it suitable for large basements, extensive crawl spaces, or open commercial areas. When shopping, compare this coverage against smaller units rated for single rooms. This broad area rating indicates the machine has the power to circulate and dry air across a significant footprint.
Drainage Method: Built-in pump, gravity drain hose
This feature includes a built-in pump that can push water vertically up to 19.6 feet, plus a gravity drain hose. You can choose to drain water upward through a window or sink, or let it flow out naturally. This flexibility is critical for crawl spaces where floor drains are absent. Compare this to units that only support gravity drainage, which require a lower exit point.
Model: Helios MP55
The specific model name is Helios MP55. This identifier helps you locate exact replacement parts, filters, or accessories like the optional hanging kit. It also distinguishes this pro-grade unit from other AlorAir models. When comparing products, use this model number to ensure you are looking at the correct specifications for the 120-pint capacity and corrosion-resistant casing design.
Design and Build Quality
The AlorAir Helios MP55 is a large, white unit with dimensions of 12.6 inches wide, 14.2 inches high, and 17.9 inches deep. It weighs 41.7 pounds. This size and weight make it a substantial piece of equipment. You will need a solid, level surface to support it. The listing states the casing is corrosion-resistant. This design choice helps the unit withstand dust and moisture in demanding spaces like crawl spaces, basements, and garages. It is built for year-round operation in these specific environments.
According to the listing, the unit features a built-in pump for flexible drainage. This allows you to discharge water vertically up to 19.6 feet. You can also use the included gravity drain hose for continuous drainage to a nearby floor drain. This dual drainage method simplifies installation in tight or elevated spaces. The control layout supports a set-and-forget operation. It includes automatic defrost, GPP mode, and pump mode. The unit automatically restarts and retains previous settings after a power outage. This reduces the need for manual adjustments.
The finish is a simple white color. This is typical for commercial and industrial equipment. The design prioritizes function over aesthetics. You can install optional accessories like a hanging kit to reduce vibration. A stable installation kit is also available to provide a secure platform. These options help minimize operating noise. The unit is ETL-listed for safety. It comes with a 6-year limited warranty. The first two years offer full coverage. This reflects the manufacturer's commitment to reliability.
Setup and Everyday Use
You install this unit by choosing between gravity drainage or the built-in pump. The included gravity drain hose allows continuous water removal to a nearby floor drain. If no floor drain is available, you can activate the integrated pump. This pump discharges water vertically up to 19.6 feet. This feature is useful for crawl spaces where upward removal through a window or sink is required. The unit is large, measuring 12.6 inches wide, 14.2 inches high, and 17.9 inches deep. It weighs 41.7 pounds, so you should place it on a stable surface. For reduced vibration and noise, you can purchase the optional hanging kit separately. You also have the option to buy a remote control for convenience. Daily operation is automatic. The device features automatic defrost and GPP mode to maintain optimal performance. If power is lost, the unit restarts automatically and retains your previous settings. This set-and-forget approach helps you maintain balanced humidity with minimal oversight. The corrosion-resistant casing is designed to withstand dust and moisture in demanding environments. You can also install washable filters to protect internal components from airborne particles. These filters are available as a separate accessory. The unit is ETL-listed, which indicates it meets specific safety standards. You can rely on this equipment for consistent humidity control in areas up to 1,500 square feet.
What You Need To Know
This unit is engineered for demanding environments, so you must verify that your crawl space or basement can accommodate its 12.6 by 14.2 by 17.9-inch footprint. The 41.7-pound weight suggests you need a stable, level platform to minimize vibration. While the casing is corrosion-resistant, you should consider purchasing the optional washable filters to protect internal components from dust and airborne particles. These filters are sold separately but are essential for long-term reliability in dusty spaces. You also need to check if you require the remote control or hanging kit, as these are not included. The built-in pump allows vertical discharge up to 19.6 feet, but you must ensure you have the necessary tubing and drainage path. Compared to standard residential models, this device offers pro-grade performance. It fits alongside other commercial-grade options in our guide for users who need serious moisture removal. You should confirm that your electrical outlet can handle the load and that you have space for the included gravity drain hose if you choose that method over the pump.
Check before you buy
- Verify your space can fit the 12.6 by 14.2 by 17.9-inch unit.
- Purchase optional washable filters to protect internal components from dust.
- Check if you need the remote control or hanging kit.
- Ensure you have a stable, level platform to minimize vibration.
