Top 3 150 Pint Commercial Dehumidifiers Reviewed
#1 MOUNTO 150 Pint Compact LGR Dehumidifier: Best Overall
Why We Picked It
MOUNTO’s compact 150 pint LGR dehumidifier pairs a Panasonic compressor with a built-in pump, removes 80 pints a day at AHAM and stacks for storage and transport.
This MOUNTO is a compact restoration-style unit. It uses LGR technology and a Panasonic compressor to keep pulling moisture as a space dries, and MOUNTO rates it at 150 pints a day at saturation and 80 pints at AHAM. The body is compact and stackable, which saves room in a van or a storage area when you own several units. A built-in pump drains condensate to wherever you need it, and a memory restart function resumes operation after a power break. It is ETL certified and weighs 65 pounds, light for an LGR unit of this capacity. MOUNTO pitches it for basements, warehouses and water damage restoration.
Key Specifications
- Capacity: 150 pints at saturation, 80 pints at AHAM
- Technology: LGR, Panasonic compressor
- Drainage: Built-in pump
- Design: Compact and stackable
- Controls: Memory restart
- Certification: ETL
- Weight: 65 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
LGR adds cost. If you only need to hold a basement at a set humidity, a standard 150 pint unit is cheaper.
Best For
This dehumidifier is best for restoration crews, basements and warehouses.

#2 Waykar 150 Pint Energy Star Dehumidifier with Pump: Best Energy Star Pick
Why We Picked It
Waykar’s 150 pint commercial dehumidifier is ENERGY STAR certified, covers up to 7,000 sq ft, includes a pump and a self-drying mode, and weighs only about 39 pounds.
This is a lighter, efficient choice for large rooms, basements and light commercial spaces. Waykar rates it at 150 pints a day at 95 degrees F and 90% humidity, coverage up to 7,000 square feet and a humidity range of 30% to 80%. It is ENERGY STAR certified, which keeps running costs down, and a self-drying function dries the coil after use to limit odors. Auto defrost lets it work in cooler cellars. You get three drainage options, including a built-in pump, so it can sit in the lowest corner of a basement. At about 39 pounds and 24 inches tall it is far easier to carry than heavy commercial boxes.
Key Specifications
- Capacity: 150 pints at saturation
- Coverage: Up to 7,000 sq ft
- Certification: ENERGY STAR
- Drainage: 3 options including a pump
- Humidity range: 30% to 80%
- Extras: Self-drying, auto defrost
- Weight: About 39 pounds
| Pros | Cons |
|---|---|
|

Things to Consider
It is closer to a large household unit than a job-site machine, so it suits basements and storage areas more than flood work.
Best For
This dehumidifier is best for large basements, wine cellars and storage areas.

#3 AVAHUM 150 Pint Energy Star Dehumidifier with Pump: Best Drainage Options
Why We Picked It
AVAHUM’s 150 pint ENERGY STAR dehumidifier covers up to 7,000 sq ft and gives you three ways to drain: a pump with 16.4ft of lift, a gravity hose or a 2.1-gallon tank, with a 5-year limited warranty.
Few large-capacity units offer a tank, a gravity hose and a pump together, and that makes this AVAHUM easy to fit into almost any space. It removes up to 150 pints a day at 95 degrees F and 90% humidity, covers up to 7,000 sq. ft. and is ENERGY STAR certified. The built-in pump lifts water 16.4ft vertically, the gravity hose handles floor drains, and the 2.1-gallon reservoir has an auto-stop sensor for spots with no drain at all. Casters and heavy-duty handles help you move it, and the 24H timer schedules running. AVAHUM backs it with a 5-year limited warranty.
Key Specifications
- Capacity: 150 pints at saturation
- Coverage: Up to 7,000 sq ft
- Certification: ENERGY STAR
- Drainage: Pump with 16.4ft lift, gravity hose or 2.1-gallon tank

What to Expect from 150 Pint Commercial 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.
For more options, see our guides to commercial dehumidifiers and Energy Star commercial dehumidifiers. For single rooms, our portable compressor dehumidifiers guide covers bucket models. The product cards show the current price for each dehumidifier.
How to Choose 150 Pint Commercial 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.
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.
Look for ENERGY STAR
A crawl space unit may run thousands of hours a year, so efficiency matters more than purchase price over its life. ENERGY STAR models remove the same water with noticeably less power.
What Makes a Dehumidifier Commercial
Commercial dehumidifiers use larger compressors and fans, metal or rotomolded housings, wheels and handles, and continuous drainage through a hose or pump instead of a bucket. They are built to run for long hours in basements, warehouses and job sites, and many add auto restart after a power cut and automatic defrost for cool spaces.
How We Evaluate 150 Pint Commercial 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 150 pints at saturation, then weighed AHAM data, drainage and efficiency.
Frequently Asked Questions
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.
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.
How much does a crawl space dehumidifier cost to run?
It depends on capacity, efficiency and how often it cycles. ENERGY STAR units and a sealed crawl space both cut running time.
Final Verdict
The MOUNTO 150 Pint Compact LGR Dehumidifier is the best 150 pint commercial dehumidifier, an LGR unit with 80 pints at AHAM, a pump and a stackable body. For efficiency, choose the Waykar 150 Pint Energy Star Dehumidifier with Pump, and for flexible drainage, the AVAHUM 150 Pint Energy Star Dehumidifier with Pump.
