The short answer
How Lgr Dehumidifiers Work
An LGR dehumidifier uses a refrigerant coil to chill the air, causing moisture to condense into a collection tank or drain. Unlike a standard unit, it then passes the air over a second, warmer coil. That reheating step lowers the relative humidity of the air, so the unit can keep pulling water even as the room gets drier.
The result is a machine that removes more water per day in typical conditions. That matters after a leak or flood, when walls, flooring, and furniture hold trapped moisture. The air needs to be very dry to encourage that moisture to evaporate, and an LGR unit does that more effectively than a basic dehumidifier.
- Condenses moisture on a cold coil
- Reheats air to lower humidity further
- Works well in cooler or damp spaces
- Commonly used after water damage
- Helps dry porous materials like wood and drywall
Why Lgr Units Matter After Water Damage
After a leak or flood, the goal is to dry the structure as quickly as possible to prevent warping, swelling, or mold growth. Standard dehumidifiers may struggle once the air gets moderately dry, leaving hidden moisture in walls or under floors. An LGR unit keeps working at lower humidity levels, pulling out that stubborn moisture.
The pros often use several LGR units together with air movers to speed up evaporation. This combination is common in water damage restoration. If you are handling a small spill yourself, a standard household dehumidifier might be enough, but for larger incidents, professional-grade LGR equipment is usually a better fit.
Key Differences from Standard Dehumidifiers
Standard refrigerant dehumidifiers are designed for everyday dampness, like a humid laundry room or crawl space. They reach a certain humidity level and become less efficient. LGR units are built to push humidity much lower, often below 30 percent, which is too dry for comfort but ideal for drying out wet building materials.
Another difference is durability. LGR units are built for heavy use on job sites, with robust components and continuous drainage options. They also tend to be larger and louder than home models. For a homeowner, renting one after a flood might be wise, but operating it correctly takes some know-how.
When to Consider Professional Dehumidification
If water has soaked into drywall, carpet, or wood for more than a day, the risk of mold and structural damage rises. In those cases, professional dehumidification services can be worth it. The pros have the equipment and experience to set up the right number of units and monitor moisture levels over several days.
If you live in a hot, humid climate, humid conditions can slow natural drying, making professional help more valuable. A water damage inspection can identify hidden moisture that you might miss. Acting quickly is key, as delaying can lead to more extensive repairs and higher costs.
- Water damage from a burst pipe
- Flooding after a storm
- Visible mold or musty odors
- Wet drywall or soaked carpets
- Moisture that lingers after a cleanup
What to Expect from a Dehumidification Process
When the pros handle dehumidification, they usually start by measuring moisture levels in the air and materials. Then they place LGR units and air movers strategically to create a drying pattern. The equipment runs continuously for days, and the pros check progress regularly, adjusting the setup as needed.
The process is not instant. Drying thick materials like hardwood or drywall can take several days, and the equipment may be loud. The pros might also need to remove damaged flooring or drywall if it cannot be saved. The goal is to return your home to a dry, safe condition, but the exact steps depend on the extent of the damage.

Can I rent an LGR dehumidifier myself?
Yes, you can rent one from equipment rental stores or some hardware stores. However, using it effectively requires knowing how many units you need and where to place them. Improper setup can leave moisture behind. For large or long-standing water damage, professional help is often safer.
How long does LGR dehumidification take?
The drying time depends on the amount of water, the materials affected, and the humidity levels. It can take anywhere from a few days to a week or more. The pros monitor moisture levels and stop when readings are back to normal. Acting quickly shortens the process.
Is LGR technology safe for my home?
Yes, LGR dehumidifiers are safe when used properly. They run on electricity and produce no fumes. The main concerns are noise and heat output, which are normal. Keep the unit on a level surface and empty the water collection regularly if not using a drain hose.
