Choosing between a 50 Pint vs 70 Pint dehumidifier depends on your space and moisture load. Both units feature built-in pumps for continuous drainage and cover damp areas like basements or crawl spaces. The main difference lies in capacity and coverage. The Midea model removes 50 pints daily for larger areas up to 4,500 square feet. The ALORAIR Helios MP35 removes 70 pints under saturated conditions but covers up to 1,000 square feet. You must weigh daily moisture removal against the specific environment you need to dry.

50 Pint vs 70 Pint Specs
Moisture Capacity
The ALORAIR Helios MP35 offers a higher maximum moisture removal capacity of 70 pints per day under saturated conditions. The Midea model removes 50 pints per day. This difference matters if you have a very wet space or high humidity loads. The ALORAIR also lists a 35 PPD rating under AHAM standards, which is a common testing benchmark. The Midea does not list an AHAM rating. If you need to pull the most water possible from the air, the ALORAIR has the advantage in raw capacity numbers.
Coverage Area
Coverage area specifications differ significantly between these two units. The Midea 50-Pint Dehumidifier with Pump is rated for spaces up to 4,500 square feet. In contrast, the ALORAIR 70-Pint Crawl Space Dehumidifier with Pump covers up to 1,000 square feet. This suggests the Midea is designed for larger, more open residential areas like basements or offices. The ALORAIR is targeted at smaller, more confined damp environments like crawl spaces or attics. For large open floors, the Midea covers more ground.
Pump Lift
Both units include a built-in pump for continuous drainage, but the ALORAIR specifies the pump's vertical lift capability. It can discharge water up to 19.6 feet vertically. This is useful for crawl spaces where you need to pump water up through a window or to a higher floor drain. The Midea data confirms it has a built-in pump that removes collected water automatically, but it does not list the maximum lift height. If you need to pump water up a significant distance, the ALORAIR provides the specific performance data to verify it will work.
Smart Controls
The Midea model includes Wi-Fi connectivity and smart control features. You can manage it via the MSmartHome app on iOS or Android. It also supports voice commands through Alexa or Google Assistant. The ALORAIR data does not mention Wi-Fi, app control, or voice assistant compatibility. It focuses on automatic defrost and pump mode for set-and-forget operation. If you want to monitor or adjust humidity settings remotely from your phone, the Midea is the better choice. The ALORAIR relies on local controls.
Noise Level
The Midea 50-Pint Dehumidifier with Pump specifies a noise level of 47 dBA. This is considered quiet operation, suitable for bedrooms or offices. The ALORAIR data does not list a decibel rating. It mentions an optional hanging kit to reduce vibration and operating noise, but no specific sound level is provided in the specs. Without a decibel figure for the ALORAIR, you cannot directly compare the noise output. The Midea gives you a concrete number to judge if it will disturb you in a living space.
Warranty
The ALORAIR Helios MP35 comes with a 6-year limited warranty, with the first 2 years offering full coverage. The Midea data does not mention a warranty period. A longer warranty can indicate manufacturer confidence in durability, especially for commercial or crawl space use. The ALORAIR is also ETL-listed, which is a safety certification. The Midea is UL listed in its features, which is also a safety certification. For long-term protection, the ALORAIR provides a clearly stated multi-year warranty plan.
Which Dehumidifier Suits Your Needs
Large basement owners needing high capacity
The Midea 50-Pint model covers up to 4,500 square feet. It removes 50 pints of moisture daily. This higher coverage area suits large spaces better than the 1,000 square foot limit of the ALORAIR unit. You also get smart app control and voice assistant compatibility for easy monitoring.
Crawl space users requiring vertical drainage
The ALORAIR Helios MP35 pumps water vertically up to 19.6 feet. This feature is essential for crawl spaces where gravity drainage is difficult. The corrosion-resistant casing withstands dusty, moist environments. Its pro-grade design targets saturated conditions, making it ideal for demanding areas that need reliable, year-round operation.
Buyers wanting smart home integration
The Midea unit connects to Wi-Fi and works with the MSmartHome app on iOS or Android. You can control it remotely or use voice commands via Alexa or Google Assistant. The ALORAIR model lacks these smart features in the provided data, making the Midea the better choice for connected homes.
Users prioritizing warranty and durability
The ALORAIR dehumidifier includes a six-year limited warranty with full coverage for the first two years. It is ETL-listed for safety. The Midea model is renewed and does not list a specific warranty duration in the provided data. If long-term protection and certified safety standards are your priority, the ALORAIR is the stronger option.

Frequently asked questions
Does a 70 pint dehumidifier use more electricity than a 50 pint unit?
Higher capacity models often require more power to remove greater volumes of moisture. The ALORAIR 70-Pint unit is designed for larger moisture loads, which may increase energy consumption compared to the Midea 50-Pint model. Check the Energy Star rating on the label to compare efficiency. Units with built-in pumps, like both listed options, add minor electrical draw for the drainage system.
Can I use a 50 pint dehumidifier in a large basement?
Yes, if the space is under 500 square feet. The Midea 50-Pint Dehumidifier with Pump covers up to 500 square feet effectively. If your basement exceeds this area, the unit may struggle to maintain low humidity. For larger basements, consider the 70-Pint ALORAIR model, which handles higher moisture loads and suits medium-sized crawl spaces or larger damp areas.
Do I need a dehumidifier with a pump for my crawl space?
A pump allows water to drain vertically, which is essential if your floor is below the drain line. Both the Midea and ALORAIR models include built-in pumps. This feature eliminates the need to manually empty a water tank. It is highly recommended for crawl spaces where gravity drainage to a floor drain is not possible.
What is the size difference between the Midea and ALORAIR units?
The ALORAIR 70-Pint model has specific dimensions of 11.8 inches wide, 13.1 inches high, and 16.1 inches long. The Midea 50-Pint model is described as medium size but lacks precise dimensions in the data. Both are compact enough for tight spaces. Check the clearance requirements in your installation area to ensure proper airflow around the unit.
Which model is better for automatic water drainage?
Both the Midea 50-Pint and ALORAIR 70-Pint models feature built-in pumps for automatic drainage. You can connect a hose to continuously remove water without manual intervention. This is ideal for basements or crawl spaces where you want to maintain consistent humidity levels without checking a bucket. Both units support this hands-free operation.
Is the Midea 50-Pint unit suitable for large spaces?
The Midea 50-Pint model covers up to 500 square feet. This capacity suits moderate dampness in standard rooms or smaller basements. It is not designed for very large open areas. If you need to treat a space larger than 500 square feet, the 70-Pint ALORAIR unit offers greater moisture removal capacity for more demanding environments.
