What this dehumidifier is built to do
- Rated capacity: 70 pints per day in saturated conditions.
- AHAM-rated capacity: 35 pints per day.
- Pump lifts water vertically up to 19.6 feet.
Damp air under a house or in a garage is a stubborn problem, and the ALORAIR Helios MP35 is built to take it on. The manufacturer rates it to pull up to 70 pints per day in saturated conditions, or 35 pints per day under AHAM standards, covering rooms up to 1,000 square feet.
The feature that separates it from a typical residential unit is the built-in pump. Where a floor drain sits nearby, you can run the included gravity hose and let water flow out. Where it does not, the pump pushes condensate upward as much as 19.6 feet, which is what makes a low crawl space or a basement corner workable.
We'd consider this a sensible pick if you're dealing with a crawl space, basement, attic, garage or light commercial room and want set-and-forget operation. It restarts on its own after a power outage and keeps the settings you left it with, so you aren't resetting the unit every time the power blinks.
What this price means for the money
At $372.86, this unit is $22.45 under the typical price over the last 90 days of $395.31, a 6% difference. That also matches the lowest price we've seen, which ran through the all-time window.
The price story here is modest rather than dramatic. You're saving a little against the recent average on a machine built for a specific job, and the value depends on whether that job matches your space.

Placement, drainage and daily care
Plan the drain route before you buy. A gravity hose handles continuous drainage when a floor drain sits lower than the unit, and the pump takes over when you need water to climb to a window or sink. The pump mode, GPP mode and automatic defrost are there for a reason, so leave the unit in the mode that suits the space.
The casing is corrosion-resistant for dusty, humid rooms, which matters in crawl spaces and unfinished basements. AlorAir also sells a hanging kit, washable filters, a remote control and a stable installation kit separately. If you want those, budget for them on top of the unit price.
A level, stable base keeps vibration and noise down, whether you set it on a platform or hang it. Clean or replace the filters on whatever schedule suits your dust level, since that's what protects the internal components.
When this is the wrong machine
Skip it if you just need to dry a small bedroom or closet. A unit rated for up to 1,000 square feet is more capacity than a single room needs, and you'd pay for a pump you never use.
Also pass if you want a portable unit you can move from room to room. This is a permanent installation built around a fixed drain route, not a rolling appliance.
Before you buy, confirm the exact pump lift and cord length work with your layout. Those are the details that decide whether the installation goes smoothly.
