ALORAIR 70-Pint Crawl Space Dehumidifier Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you manage moisture in a low-clearance area, evaluating alorair 70 pints energy star crawlspace dehumidifier alternatives helps you match equipment to your exact site conditions. The original ALORAIR Helios D35 extracts 35 pints per day at AHAM conditions and 70 pints at saturation for spaces up to 1,000 square feet. It stands just 10.8 inches tall, weighs 25.1 pounds, runs quietly below 52 decibels, and includes an auto-defrost sensor alongside a standard gravity drain hose.
You might prefer an alternative if your crawl space lacks a ground-level drain and requires an integrated pump to move condensate vertically. A larger space might call for 120 pints of saturation capacity, broader coverage up to 5,000 square feet, or a different brand offering rugged metal construction. The 6 alternatives below were selected because their core performance specs—such as compact heights, 70-pint moisture removal tiers, and Energy Star efficiency—overlap directly with the original model.
Our top pick: ALORAIR 70-Pint Crawl Space Dehumidifier.
How the Alternatives Compare
Waykar 70-Pint Crawl Space Dehumidifier with Pump
The Waykar AFW1.5DPM adds an integrated condensate pump with 16.4 feet of vertical lift, whereas the ALORAIR Helios D35 relies strictly on gravity drainage through a hose. It also lists a larger coverage rating of up to 5,000 square feet compared to the 1,000 square feet on the original unit. In exchange, the Waykar occupies more physical clearance. Its 13.2-inch height and 13.6-inch width exceed the 10.8-inch height and 11.3-inch width of the ALORAIR. Choose the Waykar if you must push condensed water upward out of your crawl space or basement and have enough vertical room for the taller frame.
Moiswell 70-Pint Crawl Space Dehumidifier with Pump
The Moiswell Defender SP60 includes a built-in condensate pump, giving you active vertical drainage that the gravity-only ALORAIR Helios D35 lacks. Its chassis measures 13 inches long, making it shorter than the 16.4-inch ALORAIR. What you give up is lightness and profile height. The Moiswell weighs 43.7 pounds, which is noticeably heavier than the 25.1-pound original, and its 12.4-inch height and 15.5-inch width demand more vertical and lateral clearance than the 10.8-inch by 11.3-inch Helios D35. Pick the Moiswell if your crawl space setup requires motorized pump discharge rather than downward gravity routing and your access point can accommodate the extra weight.
Yaufey 70-Pint Commercial Dehumidifier
The Yaufey AYD1.5D matches the 70-pint capacity of the ALORAIR Helios D35 but is rated to manage spaces up to 5,000 square feet rather than 1,000 square feet. Like the original, it operates with gravity drainage and holds an Energy Star certification. However, you sacrifice portability and compact dimensions. The Yaufey weighs 41.3 pounds, making it heavier than the 25.1-pound ALORAIR. It also stands 11.8 inches tall and 16.5 inches wide, taking up more space than the original 10.8-inch height and 11.3-inch width. Choose the Yaufey if you manage a larger crawl space or basement where gravity drainage is already accessible.
ALORAIR 70-Pint Crawl Space Dehumidifier with Pump
The ALORAIR Sentinel HD35PS upgrades your drainage options by integrating an internal condensate pump capable of 19.6 feet of vertical lift. This eliminates the slope requirement of the gravity-drained Helios D35 while maintaining the same 70-pint saturation capacity and 1,000-square-foot coverage. To get that internal pump, you give up some portability. The Sentinel HD35PS weighs 36.3 pounds, compared to the 25.1 pounds of the Helios D35, and its height increases slightly from 10.8 inches to 11.4 inches. Pick the Sentinel HD35PS if you want an Energy Star ALORAIR unit that can push collected water upward through a wall or window without an external pump.
ALORAIR 70-Pint Crawl Space Dehumidifier with Pump
The ALORAIR Helios MP35 provides an integrated condensate pump, enabling vertical drainage that the gravity-dependent Helios D35 cannot handle on its own. Both units handle 70 pints at saturation across crawl spaces up to 1,000 square feet. However, the MP35 has a taller profile at 13.1 inches high and 11.8 inches wide, requiring more overhead room than the 10.8-inch-tall, 11.3-inch-wide D35. It also does not list the Energy Star certification found on the base Helios model, and accessories like hanging kits require separate purchases. Choose the Helios MP35 if your crawl space layout requires pumping water upward to an exit point.
ALORAIR 120-Pint Crawl Space Dehumidifier
The ALORAIR Sentinel HD55S delivers significantly higher moisture removal, extracting 120 pints at saturation and covering up to 1,300 square feet, compared to 70 pints and 1,000 square feet on the Helios D35. Both include automatic defrost and Energy Star certification. The trade-off comes in physical footprint and weight. The Sentinel HD55S weighs 41.7 pounds, well above the 25.1-pound Helios D35, and its frame measures 19.2 inches long, 12.2 inches wide, and 13.3 inches high versus the original 16.4 by 11.3 by 10.8 inches. Pick the Sentinel HD55S if you need greater daily moisture extraction and have gravity drainage available.

Frequently asked questions
Which crawl space dehumidifier has the lowest height profile?
The ALORAIR Helios D35 has the lowest height profile among these picks at 10.8 inches. If you need a unit with built-in pump drainage instead, the ALORAIR Sentinel HD35PS measures 11.4 inches high, followed closely by the gravity-draining Yaufey AYD1.5D at 11.8 inches. Low profiles allow easier positioning between floor joists and tight crawl space foundations.
Which alternative provides the highest vertical pump lift for drainage?
The ALORAIR Sentinel HD35PS provides the highest vertical lift among these units with its 19.6-foot pump. This specification lets you push condensed water upward into distant waste lines or ground-level exits when your crawl space lacks floor drains. By comparison, the Waykar AFW1.5DPM lists a 16.4-foot pump lift, while the Helios D35 relies solely on unpowered gravity lines.
Which crawl space dehumidifier is the easiest to carry and maneuver?
The ALORAIR Helios D35 is the lightest unit on the list, weighing 25.1 pounds. Its lighter weight simplifies dragging or lifting through cramped access hatches. If you require an internal pump, the ALORAIR Sentinel HD35PS weighs 36.3 pounds, whereas metal-cased options like the Moiswell Defender SP60 and Yaufey AYD1.5D exceed 40 pounds, requiring more effort during crawl space placement.
Is there an alternative with higher moisture removal capacity than 70 pints?
Yes, the ALORAIR Sentinel HD55S provides a larger 120-pint saturation capacity for heavier moisture problems. Rated for areas up to 1,300 square feet, this model pulls more water per day than the standard 70-pint alternatives. It uses gravity drainage and automatic defrost, but measures 19.2 inches long and weighs 41.7 pounds, making its physical footprint larger than the 70-pint base model.
Which crawl space dehumidifier alternatives feature rugged metal housing?
Both the Moiswell Defender SP60 and the Yaufey AYD1.5D specify rugged metal construction in their chassis design. Metal housings withstand rough handling and abrasive contact with gravel or concrete crawl space floors. The Moiswell pairs its metal frame with an internal pump in a 12.4-inch chassis, while the Yaufey provides a 11.8-inch metal casing designed for locations with accessible gravity drain routing.
Which models rely strictly on gravity drainage rather than an internal pump?
The ALORAIR Helios D35, Yaufey AYD1.5D, and ALORAIR Sentinel HD55S rely on gravity drainage without built-in condensate pumps. You must route their drain hoses downward toward a floor drain, sump pit, or exterior slope. If your installation requires moving water up joists or out through high foundation vents, choose pump-equipped models like the Waykar AFW1.5DPM, Moiswell Defender SP60, or ALORAIR Sentinel HD35PS instead.
