Choosing between a 70 Pint vs 120 Pint dehumidifier depends on your space size and drainage needs. Both units remove moisture from damp environments like basements and crawl spaces. The main difference lies in capacity and coverage. The 70-pint model targets smaller areas up to 1,000 square feet, while the 120-pint unit handles spaces up to 6,000 square feet. You must also consider drainage methods. One includes a built-in pump for vertical discharge, while the other relies on a tank or gravity hose.

70 vs 120 Pint Dehumidifier Specs
Moisture removal capacity
The ALORAIR Helios MP35 delivers up to 70 pints of water removal per day under saturated conditions. Under AHAM standards, this capacity drops to 35 pints per day. This makes it suitable for moderate humidity control in smaller spaces. The Waykar JD025CE-120 offers a significantly higher capacity of 120 pints per day at 95°F and 90% relative humidity. This higher output allows it to handle much larger volumes of moist air. You will notice a clear difference in how quickly each unit can dry out a room. The Waykar removes more than three times the moisture of the ALORAIR in ideal conditions. This makes the Waykar better for very damp environments.
Coverage area
Square footage requirements differ greatly between these two models. The ALORAIR unit is designed for areas up to 1,000 square feet. This covers typical crawl spaces, small basements, or garages. The Waykar model supports spaces up to 6,000 square feet. This allows it to serve whole homes or large commercial areas. If you have a large open plan basement or a warehouse, the ALORAIR will struggle to maintain low humidity levels. The Waykar covers six times the area. You need to match the capacity to your actual square footage to avoid overworking the compressor.
Drainage options
Water removal methods vary significantly between these units. The ALORAIR includes a built-in pump that can discharge water vertically up to 19.6 feet. This is crucial for crawl spaces where gravity drainage is impossible. It also supports standard gravity drain hoses for downward flow. The Waykar relies on a 4.3-liter internal water tank or a gravity drain hose. It lacks a pump, so you must place it near a floor drain or empty the tank manually. The ALORAIR offers more flexibility for difficult installations. The Waykar is simpler but requires more maintenance if you do not have a nearby drain.
Humidity control range
The precision of humidity control affects comfort and energy use. The Waykar allows you to set humidity levels between 30% and 80% relative humidity. This wider range lets you choose deeper drying for storage areas or higher levels for living spaces. The ALORAIR features automatic defrost and GPP mode but does not specify a user-adjustable humidity range in the provided data. This suggests a more fixed operation mode. The Waykar gives you more control over the exact moisture level in your space. You can tailor the settings to protect specific items or meet comfort preferences.
Airflow design
Air distribution impacts how evenly a room dries. The Waykar features a 90-degree auto-swing airflow function. This moves dry air around the room to eliminate humidity pockets and improve circulation. The ALORAIR does not mention an auto-swing feature in its specifications. It likely uses a fixed airflow direction. The Waykar design helps cover larger areas more effectively by distributing air. This reduces the chance of damp spots remaining in corners or distant parts of the room. If you have a wide space, the swinging airflow provides better coverage.
Which Dehumidifier Fits Your Space
Crawl space owners needing vertical drainage
The ALORAIR Helios MP35 includes a built-in pump that discharges water vertically up to 19.6 feet. This feature allows you to install the unit in tight crawl spaces where gravity drainage is impossible. You can direct water through a window or sink without complex plumbing, ensuring reliable operation in demanding environments with limited floor space.
Users with large basements up to 6000 sq ft
The Waykar JD025CE-120 removes up to 120 pints of moisture daily, covering areas up to 6,000 square feet. Its 90-degree auto-swing airflow distributes dry air evenly, eliminating humidity pockets. This high capacity and wide coverage make it ideal for large basements or whole-home moisture control, ensuring consistent dehumidification across expansive spaces without cold spots.
Those wanting precise humidity control between 30-80%
The Waykar unit offers a target humidity range of 30% to 80% RH, allowing deeper drying for storage areas or post-rain conditions. Standard units often limit you to 40% RH minimum. This wider range helps you avoid over-dehumidification, protecting furniture and fabrics while maintaining energy efficiency during extended operation in varying seasonal conditions.

Frequently asked questions
Can a 70 pint dehumidifier handle a large basement?
A 70 pint unit is generally not ideal for large basements. The ALORAIR Helios MP35 is designed specifically for crawl spaces and smaller, tight areas. Its medium size and 70 pint capacity target moderate humidity levels in confined spaces rather than expansive rooms.
What is the size difference between the 70 pint and 120 pint models?
The 120 pint Waykar model is taller and slightly narrower than the 70 pint ALORAIR unit. The Waykar JD025CE-120 measures 21.9 inches in height and weighs 34 pounds. The ALORAIR Helios MP35 is shorter at 13.1 inches tall and has a more compact footprint.
Which dehumidifier is better for a 6000 square foot space?
The 120 pint Waykar dehumidifier is the better choice for a 6000 square foot area. It is explicitly rated for large basements and commercial spaces with that coverage. The 70 pint model is intended for smaller environments like crawl spaces and would be insufficient for such a large volume.
Do I need a pump with a 70 pint dehumidifier?
You need a pump if gravity drainage is not possible in your installation spot. The ALORAIR Helios MP35 includes a built-in pump to discharge water vertically. This is essential for tight crawl spaces where you cannot rely on a standard drain hose flowing downward.
Is the 120 pint dehumidifier Energy Star certified?
Yes, the Waykar 120 pint model is Energy Star certified. This certification indicates it meets specific energy efficiency guidelines set by the EPA. It is designed for users who need high capacity in large spaces while maintaining energy-conscious operation.
Can the 70 pint unit drain water automatically without manual emptying?
Yes, the ALORAIR Helios MP35 can drain water automatically using its internal pump. It allows for continuous operation in demanding environments like crawl spaces. You do not need to manually empty a tank if you utilize the vertical drainage feature provided by the pump system.
