When it comes to dehumidifiers, the basic difference between types is durability and capacity. Residential dehumidifiers typically are designed for smaller spaces and are made of mostly plastic parts. Design-wise, residential dehumidifiers are made to look more aesthetically pleasing than their commercial counterparts.
Commercial or industrial dehumidifiers, on the other hand, are made of more durable materials (steel) that are designed to withstand more rugged conditions (temperature swings, etc). Most of these dehumidifiers have larger capacities (that is, remove more humidity) than residential models. They are also louder.
So what are the best commercial dehumidifiers? The answer depends on your intended use. For light duty use (minor flood restoration, small office or warehouse), a top-of-the-line residential dehumidifier should do the trick.
More serious flood restoration projects or demanding environments (like an indoor pool) require a more robust solution. More on that in a second.
First, let’s go over our pick for light duty use—after speaking with contractors and doing 17 hours of research into different models, we think Vremi’s 4500 square foot dehumidifier is best.
Where would you use this dehumidifier? Offices, retail stores or other light commercial applications. Small warehouses would also work—especially if you had a drain so you could continuously run this unit.
Good news: this large-capacity dehumidifier combines both performance and value. It removes 50 pints of water from the air per day, lowering the humidity to comfortable levels in a short period of time. The tank holds 1.8 gallons of water.
Here’s more on why we recommend this model:
What We Liked
• Built-in wheels. You’d think that would be a standard feature on dehumidifiers for basements, but no. This model has wheels.
• Quickly lowered humidity.
• Auto shut off when tank is full.
• Drain hose outlet for continuous draining into a sink or floor drain.
• Turbo mode and auto defrost. The auto defrost is important, as ice buildup on the dehumidifier’s coils can cause the units to malfunction.
• Visible water level line on front of tank.
• Remembers settings after power outage.
What Needs Work
• Tank fills up to top—and can spill when you open it. That is no fun!
• Can get hot to touch.
• Hose attachment could be tighter.
