Quick list
Which one is right for you?
- For water damage crews: The Dri-Eaz LGR 7000XLi is an LGR unit with a built-in pump, the configuration used in water damage work. If you want a stated pint count, the Dri-Eaz LGR 2800i is the same type with a 130-pint-per-day figure in its product name. See pick 5
- For facility managers who want remote visibility: The ALORAIR 180 PPD is the only pick with Wi-Fi stated in its specs and it has a pump for continuous drainage, so it suits managers who want remote visibility on a commercial dehumidifier. See pick 1
- For cold or damp basements: For cold or damp basements, consider a desiccant-type pick such as the PHOENIX D385. Its spec block includes a pump and drain hose, and the seller does not state a low-temperature limit. See pick 7
- For large open commercial spaces: For spaces over 5,000 sq ft, the Waykar 216 has a stated pump and drain hose plus a washable filter in its product name. The AEOCKY 8000 is the Energy Star option in the same area class if efficiency claims matter. See pick 3

How we chose these
The pool contained 26 commercial or industrial dehumidifiers, all flagged for commercial use in the catalogue. We shortlisted 15 that represent the spread of the group: refrigerant, LGR and desiccant models; pump and drain-hose units; Energy Star listed models; and machines aimed at crawl spaces, basements, large rooms and job sites. Each pick's pros and cons are drawn from its listing's stated specifications and product name; where the seller does not give a spec, we say so instead of guessing. The prices shown beside each pick are live prices read from the store listing at the time the page loaded, so they can change. Nobody on the site has used any of these units; treat these as spec-based recommendations, not test results.
What to look for
Capacity: start with pints per day
Dehumidifier capacity is reported in pints per day under the U.S. Department of Energy test procedure. The DOE test changed in 2020 to cooler, more realistic conditions, so newer capacity figures tend to be lower than older ones for the same machine. ENERGY STAR says it is better to oversize than undersize when you are between two sizes. In this list, capacity bands run from 50 to 99 pints up to a 240-pint listing.
LGR, desiccant and standard refrigerant: what the type tells you
The pool includes standard refrigerant dehumidifiers, LGR models from ALORAIR and Dri-Eaz, and desiccant models from Phoenix, Global Industrial and Ecor Pro. ENERGY STAR notes that condensing coils can frost when air temperatures drop below about 65 degrees F, and some units have anti-frost sensors. If you work in a cooler space, compare the machine's stated type and any cold-room specifications before buying. The catalogue identifies LGR and desiccant as distinct types, and those labels matter for restoration work and cold spaces.
Pumps, drain hoses and continuous drainage
A pump lets a dehumidifier push condensate upward to a sink or floor drain; a drain-hose connection allows gravity drainage without emptying a bucket. In this list, 9 of the 15 picks state a pump and 5 state a drain hose; 4 state both. If a listing lacks one, you will either plan to drain into a bucket or add your own condensate pump.
Energy Star and efficiency claims
ENERGY STAR certified dehumidifiers use more efficient coils, compressors and fans, and they use about 20 percent less energy than conventional units of similar size. Only one pick in this list, the AEOCKY 8000, carries an Energy Star flag in its specs. If energy certifications matter to your purchasing process, keep that flag near the top of your comparison.
Operating temperature and unheated spaces
ENERGY STAR says condensing coils can frost when air temperatures drop below about 65 degrees F, and some units have anti-frost sensors. The DOE test procedure now measures capacities at 65 degrees F rather than 80 degrees F to better reflect basement conditions. For unheated garages or cold storage, look for a listing that says it is suitable for those conditions; the seller does not state a low-temperature limit for every pick.
When to use dehumidifiers before mold cleanup
EPA and CDC both say the key to mold control is moisture control and that water-damaged areas should be dried within 24 to 48 hours. CDC recommends keeping indoor humidity no higher than 50 percent if you can. A commercial dehumidifier helps with that, but cleanup still matters: remove wet materials, fix leaks, clean surfaces and keep air moving.
Questions
What size commercial dehumidifier do I need?
Start with pints per day. DOE tests dehumidifiers by measuring water removed over 24 hours under set conditions, and ENERGY STAR says it is better to oversize than undersize. Large, wet rooms need higher capacities than small, slightly damp ones. In this list, a 150-pints-or-more unit is usually aimed at big basements and commercial rooms, while 50-to-99-pint units fit smaller spaces.
What is the difference between LGR and desiccant dehumidifiers?
LGR is a type of refrigerant dehumidifier; Dri-Eaz and ALORAIR listings in this pool are marked LGR. Desiccant models, such as the Phoenix D385, Global Industrial 105 and Ecor Pro 50, use a desiccant material to absorb moisture. The seller does not publish test data beyond the listed capacities for either type, so treat the type as a selection signal and confirm the manufacturer's spec sheet for your site.
Do I need a pump or a drain hose?
A pump is needed when condensate must move upward, for example from a basement to a floor drain. A drain-hose connection lets water flow by gravity to a drain. Nine of the 15 picks state a pump and 5 state a drain hose. If neither is stated, you will likely empty a bucket, so choose a pump model for unattended operation.
Can I use a commercial dehumidifier in cold spaces?
ENERGY STAR says condensing coils can frost below about 65 degrees F and that some units have anti-frost sensors. The DOE test now measures capacities at 65 degrees F, not 80 degrees F, which is why newer capacities can look smaller. If you need to dry a cold warehouse or unheated basement, confirm the unit's stated operating range with the seller before relying on it.
How quickly should I dry a space after water damage?
EPA and CDC both recommend drying water-damaged areas within 24 to 48 hours to prevent mold growth. CDC also recommends keeping indoor humidity below 50 percent if you can. A commercial dehumidifier helps, but you still need to remove soaked materials, fix leaks, clean surfaces and ventilate.
