AlorAir Commercial Water Damage 85 Pint Dehumidifier is the best commercial dehumidifier because it is designed specifically for flood repair and drying, and the small units are stackable for different sizes, spaces and jobs.
The AlorAir Commercial Water Damage 85 Pint Dehumidifier is efficient despite its compact size, and the units are easily stackable for transportation or drying larger spaces. This unit can operate safely between temperatures of 33 and 105 degrees F, making it safe for most indoor and outdoor conditions. This model is energy-efficient, drawing just 5.5 A on a 115V power supply. It runs at a capacity of 85 PPD or 190 PPD at saturation.
Best of all, this unit is completely waterproof because the circuit board is 100% sealed with rubber, so it is ideal for jobs involving heavy water removal. The gas defrosting system allows the unit to clear ice from the dehumidifying coils as long as the temperature is at least 2 degrees Celsius (35 degrees Farhenheit). The epoxy that coats these humidifying coils helps prevent corrosion, extending the life of the dehumidifier even under extreme damp conditions like post-flooded spaces.

Features to Consider When Buying a Commercial Dehumidifier
Commercial dehumidifiers come in a variety of sizes and prices, and with all the technical jargon (AHAM? ETL? Saturation?), it can be difficult to make an informed purchase when reading reviews. Here are some of the most important features to consider when searching for the best industrial dehumidifier.
AHAM and Saturation
Often, commercial dehumidifiers will advertise two different PPD (pints per day, or pints of water removed from the air per day) values labelled “AHAM” and “Saturation.” But what do those actually mean? AHAM stands for Association of Home Appliance Manufacturers, so the AHAM value is based on the settings the AHAM recommends. The AHAM rating is based on an environment of 60% humidity and 80 degrees F, which is considered to be a realistic setting for everyday operation in normal buildings and structures.
The saturation rating is based on an environment with 90% humidity at 90 degrees F, which is a much more extreme condition that isn’t typical inside normal structures. However, this isn’t unrealistic in regularly flooded areas, so the higher saturation rating may be accurate for disaster relief in these places. The saturation rating is a measurement of the absolute most that a commercial dehumidifier can take out in a day.
Some units will list “ETL” or “ETL Listed” in their features. A product with an ETL Listed mark means that it has been tested and found acceptable by an NRTL (an OSHA Nationally Recognized Testing Laboratory), acting as a guarantee for national standards in manufacturing and distribution. This doesn’t mean that products without the ETL Listed mark are not compliant, but it does act as an extra assurance that the commercial dehumidifier meets national standards.
Many dehumidifiers advertise that they are “roto-molded” or have “roto-molded castings.” Roto-molding, or rotational molding, is a manufacturing technique that involves using a rotating mold of cast aluminum or sheet steel, which allows manufacturers to monitor the air temperature within the mold, making it easier to prevent bubbles and other imperfections that weaken the plastic. Roto-molded plastic also does not have welding or seams, which can act as weak points on other types of plastic. Without these seams, roto-molded castings have no obvious weak points.
Benefits of Using Commercial Dehumidifiers
Commercial dehumidifiers are bulkier and more expensive than dehumidifiers for your home, but they are worth the added cost in many situations. Here are some benefits of using a commercial dehumidifier.
After large natural disasters like hurricanes or floods and severe home disasters like burst pipes, the number one priority is drying everything out as quickly as possible to prevent mold growth and to manage humidity in your home. In these cases, a commercial dehumidifier and different types of fans are necessary to try to save as much of the structure as possible. Water-damaged structures serve as a home for many bugs and fungi on top of a mold, which spells further disaster for buildings.
Comfort and Allergies
Even in non-disaster scenarios, dehumidifiers can help prevent or reduce mold and mildew growth as well as other allergens such as dust mites that trigger allergic reactions and asthma symptoms. Dust mites need a relative humidity of at least 70% in order to thrive, so intentionally maintaining a lower humidity can help prevent their spread.
Low humidity can also be more comfortable in hot, humid environments because sweat evaporates more easily in low-humidity environments. The evaporation of sweat is what allows you to cool, so low-humidity environments promote the body’s natural cooling process.
Precautions of Using Commercial Dehumidifiers
While commercial dehumidifiers can be an excellent tool in many commercial, industrial, and residential circumstances, they do have some downsides that should be considered when choosing a unit.
Some models of dehumidifiers are extremely noisy. This may not be such an issue for unfinished basements, crawl spaces, or on construction and renovation sites, but the noise can be problematic in a family room or bedroom. If noise could pose a problem for your commercial dehumidifier usage, check whether the dehumidifier is built to function silently or not. Generally, larger dehumidifiers are noisier, but this is not always the case.
Especially if a large commercial dehumidifier is used for extended periods or left on for days/weeks at a time, the energy bill may increase. Oftentimes, dehumidifiers require a lot of energy. For post-flooding and post-disaster spaces, getting the area dry as quickly as possible has priority, but for consistent home basement and crawlspace usage, energy usage may be a consideration. Dehumidifiers and humidifiers that automatically turn on and off based on conditions often use less electricity, but you can generally expect an increase in energy bills depending on the model.
Filters and storage tanks must be taken apart and cleaned regularly, but different models have different maintenance needs. Commercial dehumidifiers that use a drain hose tend to be lower maintenance because there is no storage tank to deal with.
When it comes to the best commercial dehumidifier review, the Aprilaire 1830 Pro Basement 70 Pint Commercial Dehumidifier is our top pick. This model offers a great balance of size, efficiency, and price, making it a good option for a variety of moderate-power commercial, industrial, and home settings. Especially since it comes in three different PPD models, you have the ability to buy a unit customized to your needs.
No matter which commercial dehumidifier ends up being best for your needs, we hope that our suggestions and explanations were helpful in your search, whether you need post-disaster relief or want to dry a damp basement.
