Top 3 Crawl Space Dehumidifiers Under $700 Reviewed
#1 ALORAIR Sentinel HDi65S Dehumidifier: Best Overall
Why We Picked It
The Sentinel HDi65S adds a built-in condensate pump with up to 19.6 ft of lift to ALORAIR’s ENERGY STAR 120-pint crawl space platform.
When there is no floor drain, the HDi65S pushes water out instead. Its integrated condensate pump lifts water up to 19.6 ft, enough to reach a sink, window or elevated drain, and you can still use the gravity hose when a drain sits below the unit. Capacity is up to 120 pints a day at saturation and 55 PPD at AHAM, for crawl spaces, basements and storage areas up to 1,300 sq ft. The metal case, auto defrost and ENERGY STAR certification match the HD55S, so this is the version to buy when drainage is the problem.
Key Specifications
- Capacity: 120 pints at saturation, 55 PPD at AHAM
- Coverage: Up to 1,300 sq ft
- Pump Lift: Up to 19.6 ft
- Drainage: Pump or gravity
- Certification: ENERGY STAR
- Weight: 41.7 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
If a floor drain sits below the unit, the cheaper HD55S does the same job.
Best For
This dehumidifier is best for crawl spaces without a floor drain.

#2 Argendon Guardian 60P Dehumidifier: Best for Larger Spaces
Why We Picked It
Argendon’s Guardian 60P removes up to 145 pints a day at saturation and 60 PPD at AHAM, covers up to 1,800 sq ft and includes a pump and two hoses.
The Guardian 60P steps up from 120-pint units for larger crawl spaces. Capacity is up to 145 pints at saturation and 60 PPD at AHAM (80 degrees F, 60%), for areas up to 1,800 sq ft. Use the 6.5 ft gravity hose or the pump to direct water up to 19.6 feet. Auto defrost and memory start keep it running without attention, adjustable humidity settings tune its output, and a GPP readout helps track drying. It is ETL listed with a 5-year limited warranty.
Key Specifications
- Capacity: 145 pints at saturation, 60 PPD at AHAM
- Coverage: Up to 1,800 sq ft
- Drainage: Pump (19.6 ft) or 6.5 ft gravity hose
- Defrost: Automatic
- Certification: ETL
- Weight: 47.5 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
It is the better pick over a 120-pint unit when your crawl space is over about 1,300 square feet.
Best For
This dehumidifier is best for larger crawl spaces.

#3 ALORAIR 180 PPD Commercial Dehumidifier: Best Commercial
Why We Picked It
ALORAIR’s 180 PPD commercial unit removes up to 180 pints a day at saturation and 85 PPD at AHAM, yet stands just 17.3 inches tall, so it fits crawl spaces as well as job sites.
This ALORAIR is a favorite of restoration crews because it packs commercial capacity into a low, compact body. Airflow is 210 CFM, capacity is up to 180 pints a day at saturation (90 degrees F, 90% humidity) and 85 PPD at AHAM, for spaces up to 2,300 square feet. At 22.8 x 13.7 x 17.3 inches with two top handles, it slides into crawl spaces and tight basements. The built-in pump uses a 19.6 ft hose and lifts water about 14.7 ft, and the 6-year limited warranty covers it.
Key Specifications
- Capacity: 180 pints at saturation, 85 PPD at AHAM
- Coverage: Up to 2,300 sq ft
- Airflow: 210 CFM
- Drainage: Pump, 19.6 ft hose
- Size: 22.8 x 13.7 x 17.3 inches
- Weight: 64.3 pounds

What to Expect from Crawl Space Dehumidifiers Under $700
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 Crawl Space Dehumidifiers Under $700
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.
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.
Size for the Space and the Moisture Load
Coverage claims assume a sealed space. An encapsulated crawl space with a vapor barrier needs far less capacity than a vented, wet one. If you have standing water, efflorescence on walls or a musty smell throughout the house, size up.
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 Crawl Space Dehumidifiers Under $700
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 only new, in-stock units listed under the price cap, then weighed capacity, drainage and build.
Frequently Asked Questions
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.
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 is the difference between AHAM and saturation ratings?
AHAM is measured at 80 degrees F and 60% humidity; saturation at about 90 degrees F and 90%. AHAM is the better number for comparing units.
How long does it take to dry out water damage?
Typically three to five days with enough dehumidification and air movement, but it depends on materials and how wet they are.
Final Verdict
The ALORAIR Sentinel HDi65S Dehumidifier is the best crawl space dehumidifier under $700, an ENERGY STAR 120-pint unit with a pump. For larger spaces, choose the Argendon Guardian 60P Dehumidifier, and for commercial capacity, the ALORAIR 180 PPD Commercial Dehumidifier.
