Dri-Eaz LGR 3500i Dehumidifier

Type

LGR

Pump included

Yes

Commercial or industrial

Yes

$4,750.21 (as of 10/24/2026 12:32 PDT - Details)

View on Amazon

This unit has no pump, so it must rely on gravity drainage or manual emptying. That can be simpler and have fewer parts to maintain, but it also means you need a floor drain at the same level or are willing to empty the tank.

Pros

• LGR type for low-grain operation
• From an established manufacturer
• No pump to maintain

Cons

• No pump, so no automatic drainage
• Capacity not stated
• No coverage area or drain hose specified

Good fit if

• Installations with a floor drain at the same level
• Users who prefer a simple, pump-free setup

Skip if

• You need to pump water upward
• You need a stated capacity

Verdict: A bare-bones LGR for simple setups, but missing key specs for comparison.

Specs compared

How we chose these

We started with a pool of six LGR dehumidifiers listed by established makers. Each unit was assessed against its stated capacity, pump presence, drain hose inclusion, coverage area, and intended use. The selection is based on the specifications published by the manufacturers and the details in the product listing. Prices are live and read from the store listing at the time of writing.

What to look for

Capacity: pints per day

Capacity indicates how much moisture a dehumidifier can remove in 24 hours under standard operating conditions. The Department of Energy changed the measurement procedure in 2019, so newer units may display lower pint-per-day numbers than older ones. The ENERGY STAR sizing guide suggests that a large room over 2,000 square feet in a very damp condition may need 40 pints per day or more, while a wet space may need 50 pints or more. In this pool, three units state a capacity of 150 pints or more, which is well above those suggested levels and better suited to commercial or severe situations.

Drainage: pump, hose, or bucket

Every LGR in this pool except the Dri-Eaz LGR 3500i includes a pump, which lets you push condensate upward to a sink or drain. A pump is essential if your drain is above the unit. The Waykar also includes a drain hose, so you can connect it directly to a floor drain and avoid emptying a bucket. The Dri-Eaz LGR 3500i has no pump, which means you will need a gravity drain at the same level or manually empty the collection tank.

Coverage area and space size

Coverage area, usually expressed in square feet, tells you how large a space a dehumidifier can handle. In this pool, only the Waykar states a coverage area (over 5,000 sq ft). The ENERGY STAR sizing chart breaks down recommendations into small rooms (under 2,000 sq ft) and large rooms (over 2,000 sq ft), with higher capacities for very damp or wet conditions. If you have a larger space or a commercial setting, you will likely need a unit with a higher capacity, but a stated coverage area helps confirm the fit.

Operating temperature and anti-frost

Dehumidifiers can lose performance when the air temperature drops below 65 degrees Fahrenheit, and frost can form on the coils. The ENERGY STAR guidance recommends looking for a product specified for lower temperatures. LGR units are designed to operate at lower grain counts, which makes them a common choice for basements and crawl spaces, but not all models state an anti-frost feature. In this pool, none of the picks list anti-frost protection, so if you expect temperatures below 65 degrees, you may want to contact the manufacturer about low-temperature operation.

Energy efficiency and IEF

Energy efficiency for dehumidifiers is expressed by the Integrated Energy Factor (IEF), in liters of water removed per kilowatt-hour (L/kWh). A higher IEF indicates a more efficient unit. ENERGY STAR certified dehumidifiers use more efficient components and remove the same amount of moisture using 20% less energy than conventional units, according to the program. The picks here do not list their IEF values, so compare efficiency directly on the product listings or the ENERGY STAR product finder if that matters to you.

Mold control and moisture

The EPA and CDC both emphasize that the key to mold control is moisture control. The CDC recommends keeping indoor humidity below 50% and drying water-damaged areas within 24 to 48 hours to prevent mold growth. A dehumidifier is one of the tools the CDC lists for lowering humidity. For a damp basement, the University of Minnesota Extension specifically recommends getting a dehumidifier to remove moisture from the air. Pair your LGR unit with prompt repair of any leaks and proper ventilation for the best results.

Questions

What is an LGR dehumidifier?

LGR stands for low grain refrigerant. These dehumidifiers are designed to remove moisture even in cooler, damp environments like basements and crawl spaces, where standard units may be less effective. They operate by pulling air over a cold coil to condense water vapor, and they are specified for lower dew points. In this pool, all six units are marked as LGR, which makes them suitable for challenging moisture conditions.

How many pints per day do I need?

The amount of moisture you need to remove depends on the size of the space and its dampness. The ENERGY STAR sizing chart suggests that a large room over 2,000 square feet that is slightly to moderately damp may need at least 30 pints per day, and a wet space may need 50 pints or more. The picks here are all well above that, with most stated at 100 to 150 pints per day, so they are aimed at large or heavily affected areas.

Can I leave a dehumidifier running continuously?

Most dehumidifiers can run for long periods, but they will cycle on and off to maintain the set humidity level. Units with a pump can drain automatically to a floor drain, while those without a pump require you to empty the collection tank. For continuous operation, look for a unit with a pump and a hose connection, like the Waykar in this pool, which lets you set up permanent drainage.

Do I need a pump in an LGR dehumidifier?

A pump allows the dehumidifier to push water upward to a sink or drain, which is useful when your drain is above the unit's outlet. The Dri-Eaz LGR 3500i in this pool has no pump, so it needs a gravity drain at the same level or manual emptying. All other picks include a pump, which gives you more flexibility in placement.

How do I prevent mold growth in my home?

The EPA and CDC recommend controlling moisture as the key to preventing mold. Keep indoor humidity below 50%, fix any leaks in the roof, walls, or plumbing, and dry water-damaged areas within 24 to 48 hours. Use a dehumidifier in damp spaces like basements, and make sure your bathroom and kitchen fans vent to the outside. The CDC also suggests cleaning moldy surfaces with soap and water or a bleach solution.
