Top 3 LGR Dehumidifiers Reviewed
#1 ALORAIR Storm 80X LGR Dehumidifier: Best Overall
Why We Picked It
ALORAIR’s Storm 80X is an efficient LGR unit on wheels: 80 PPD at AHAM, up to 170 pints at saturation and a COP of 2.4 L/kWh, with a built-in pump.
The Storm 80X is built for restoration work and large spaces up to 2,100 sq ft. Its 200 CFM airflow and low-grain refrigerant design keep pulling water as the air gets drier, which is what drying a flooded room needs. ALORAIR lists a COP of 2.4 L/kWh, meaning it removes more water per unit of power than many units in its class. The upright body rolls on wheels with a retractable handle, the integrated condensate pump drains it continuously, and it carries the 6-year limited warranty.
Key Specifications
- Capacity: 170 pints at saturation, 80 PPD at AHAM
- Coverage: Up to 2,100 sq ft
- Airflow: 200 CFM
- Efficiency: COP 2.4 L/kWh
- Drainage: Built-in pump
- Size and Weight: 15.2 x 14.4 x 24.8 inches, 63.9 pounds
| Pros | Cons |

Things to Consider
It is a restoration and basement machine; for a low crawl space, a flat Sentinel fits better.
Best For
This dehumidifier is best for water damage drying and large basements.

#2 B-Air VG-2200 LGR Dehumidifier: Best High Capacity
Why We Picked It
B-Air’s VG-2200 removes up to 225 pints a day at saturation and 130 PPD at AHAM, and its low grain refrigerant design keeps drying in cool, dry conditions.
The VG-2200 is a professional restoration dehumidifier. Its high-efficiency rotary compressor delivers up to 225 pints a day at 90 degrees F and 90% humidity, and 130 PPD under AHAM conditions. Because it is an LGR unit, it continues removing moisture as the air gets drier and cooler, which is what finishing a water damage job requires. It is designed to be portable despite the capacity, and suits industrial, commercial and personal use.
Key Specifications
- Capacity: 225 pints at saturation, 130 PPD at AHAM
- Technology: LGR, rotary compressor
- Test Conditions: 90 degrees F, 90% RH (saturation)
- Use: Water damage, mold remediation
- Weight: 97 pounds
- Dimensions: 22.5 x 32.5 x 10 inches
| Pros | Cons |

Things to Consider
For permanent crawl space control, a smaller unit uses far less power.

#3 Moiswell RD200 LGR Dehumidifier: Best Stackable
Why We Picked It
Moiswell’s RD200 is a stackable, rotomolded LGR dehumidifier that removes up to 190 pints a day and 90 PPD at AHAM, with a built-in pump.
The RD200 is aimed at restoration crews and very wet spaces. Its rotomolded housing stands up to job-site handling, and the units stack for transport and storage. Capacity is up to 190 pints a day and 90 PPD at AHAM, with 224 CFM of airflow. An intelligent defrost system keeps it working in cold, damp environments, and a built-in pump drains it continuously.
Key Specifications
- Capacity: 190 pints per day, 90 PPD at AHAM
- Airflow: 224 CFM
- Housing: Rotomolded, stackable
- Drainage: Built-in pump
- Defrost: Automatic
- Technology: LGR

Things to Consider
It is a restoration tool first; for permanent crawl space use, a low Sentinel-style unit fits better. Crews that run several units will appreciate that they stack securely in a truck or storage room.

Other Models Worth Considering
BlueDri DH76 LGR Dehumidifier. BlueDri’s DH76 is a compact roto-molded LGR unit at 76 PPD under AHAM conditions.
MOUNTO 150 Pint LGR Dehumidifier. MOUNTO’s 150-pint LGR unit uses a Panasonic compressor and stacks for transport.
Argendon 50C LGR Dehumidifier. Argendon’s 50C LGR offers RH and GPP control modes on a wheeled body.
What to Expect from LGR 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 dehumidifiers for water damage and 180-pint 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 LGR Dehumidifiers
Know When You Need LGR
Low grain refrigerant units keep pulling water as the air gets drier and cooler, which is what drying out a flooded space requires. For maintaining a sealed crawl space, a standard unit is usually enough and cheaper to run.
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.
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 LGR 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 only LGR units, then weighed AHAM capacity, efficiency, drainage and portability.
Frequently Asked Questions
What does LGR mean?
Low grain refrigerant. These units keep removing water at low humidity and cooler temperatures, which helps finish drying jobs.
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.
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.
Final Verdict
The ALORAIR Storm 80X LGR Dehumidifier is the best LGR dehumidifier for most buyers, efficient and easy to move on wheels. For maximum capacity, choose the B-Air VG-2200 LGR Dehumidifier, and for crews that stack and transport units, the Moiswell RD200 LGR Dehumidifier.
