Top 3 70 Pint Crawl Space Dehumidifiers Reviewed
#1 ALORAIR Sentinel HS35 Dehumidifier: Best Overall
Why We Picked It
ALORAIR’s Sentinel HS35 is a compact 70-pint crawl space unit with simple manual knobs, 115 CFM of airflow and a 6.5 ft drain hose, sized for spaces up to 1,000 sq ft.
The HS35 is ALORAIR’s entry crawl space dehumidifier. It removes 35 PPD under AHAM conditions and up to 70 pints a day at saturation, moving 115 CFM of air through spaces up to 1,000 sq ft. The 6.5 ft hose drains continuously by gravity, so there is no tank to empty, and an ergonomic handle makes it easy to slide into place. Humidity is set with manual knobs, which some installers prefer because there is nothing to reprogram after an outage. Auto defrost keeps it running in cool conditions, and it carries ALORAIR’s 6-year limited warranty.
Key Specifications
- Capacity: 70 pints at saturation, 35 PPD at AHAM
- Coverage: Up to 1,000 sq ft
- Airflow: 115 CFM
- Drainage: 6.5 ft gravity hose
- Controls: Manual knobs
- Size and Weight: 15.35 x 11.2 x 11.4 inches, 37.8 pounds

#2 Argendon Shield 35P Dehumidifier: Best with Pump
Why We Picked It
Argendon’s Shield 35P is a compact 70-pint crawl space unit with two drainage options: a 19.6 ft pump hose or a 6.5 ft gravity hose.
The Shield 35P removes 70 pints at saturation and 35 PPD under AHAM conditions in spaces up to 1,000 sq ft. Both hoses are included: use the 19.6 ft pump hose to send water up and out, or the 6.5 ft gravity hose when a floor drain is nearby. Argendon includes a plug to seal the gravity port when you use the pump. The compact body suits small basements and tight crawl spaces, and auto defrost, memory start and a 5-year limited warranty are included.
Key Specifications
- Capacity: 70 pints at saturation, 35 PPD at AHAM
- Coverage: Up to 1,000 sq ft
- Drainage: 19.6 ft pump hose or 6.5 ft gravity hose
- Defrost: Automatic
- Restart: Memory start
- Weight: 38.18 pounds

#3 Airecoler Stellar S10 Dehumidifier: Best Remote Panel
Why We Picked It
Airecoler’s Stellar S10 is an ENERGY STAR 70-pint crawl space unit whose control panel detaches and works as a wired remote, so you can adjust it without crawling under the house.
The S10’s standout feature is practical: the control panel detaches and acts as a wired remote, letting you check and change settings from outside the crawl space with no extra controller. It removes up to 70 pints a day (max) and about a third of that at the cooler 65 degree F test condition, in spaces up to 1,000 sq ft. It is ENERGY STAR certified, measures only 15.5 x 13.2 x 12.3 inches for low-clearance spaces, and includes a drain hose for continuous drainage.
Key Specifications
- Capacity: Up to 70 pints per day (max)
- Coverage: Up to 1,000 sq ft
- Remote: Detachable wired control panel
- Certification: ENERGY STAR
- Drainage: Gravity hose
- Size: 15.5 x 13.2 x 12.3 inches

What to Expect from 70 Pint Crawl Space Dehumidifiers
Crawl space and whole-house dehumidifiers are built to run for months without attention. There is no bucket: water leaves through a gravity hose or a built-in pump, the coils are protected against corrosion, and auto defrost keeps them working in cool, damp spaces where a household unit would ice up and stop.

How to Choose 70 Pint Crawl Space Dehumidifiers
Compare AHAM Ratings, Not Saturation Numbers
Most listings quote two capacities. The big number is measured at saturation, around 90 degrees F and 90% humidity, conditions a crawl space rarely sees. The AHAM figure, measured at 80 degrees F and 60% humidity, is far more useful for comparing units, and it is usually about half the saturation number.
Measure the Access Opening
Crawl space doors and joist bays are tight. Measure the opening and the clearance before you buy, and look for low, flat bodies with handles. Some units can hang between joists to keep them off the ground.
Plan the Drainage First
A gravity hose works when a floor drain, sump or exterior opening sits lower than the unit. If water has to go up and out, through a rim joist or to a basement sink, choose a model with a built-in condensate pump and check its lift height.
Check the Warranty
These units are an investment, and warranties vary from one to six years or more. A long warranty from a brand with US support is worth paying for when the unit will live where you rarely see it.
How We Evaluate 70 Pint Crawl Space Dehumidifiers
We rank dehumidifiers on manufacturer specifications and listing details: rated capacity and the conditions behind it, coverage, drainage, efficiency, build and warranty. We kept only new, in-stock units and left out renewed listings and bucket-style household models. For this list we kept units rated around 70 pints at saturation, then weighed drainage, controls and warranty.
Frequently Asked Questions
What size crawl space dehumidifier do I need?
For a sealed crawl space, a unit rated around 35 PPD at AHAM suits smaller homes and about 55 PPD larger ones. Wet or vented spaces need more.
What humidity should a crawl space be?
Most experts aim for 45% to 60%. Below that wastes energy; above it invites mold and wood rot.
Do I need a pump?
Only if there is no drain lower than the unit. Otherwise a gravity hose is simpler and has no pump to fail.
Should a crawl space dehumidifier run all the time?
It should stay on, but a humidistat switches the compressor on only when humidity rises above the set point.
Final Verdict
The ALORAIR Sentinel HS35 Dehumidifier is the best 70 pint crawl space dehumidifier, simple, compact and backed by a 6-year warranty. For pump drainage, choose the Argendon Shield 35P Dehumidifier, and for a wired remote panel, the Airecoler Stellar S10 Dehumidifier.
