Commercial vs Residential dehumidifiers – which is worth? Commercial dehumidifiers have an exterior made from steel or strong plastic to withstand tough environments. Hence they last longer on average as compared to residential dehumidifiers. Not all commercial dehumidifiers have an appearance that will complement your office or home interior, unlike residential dehumidifiers. As explained, they are rugged devices and this is reflected in their design.
Commercial dehumidifiers are heavy-duty machines that have higher specifications as compared to residential dehumidifiers. Due to their ruggedness, durability and high performance, they are ideally suited for extreme conditions and large areas.
How much water will a commercial or Residential dehumidifiers remove?
Water removal is based on how many pints per 24 hours and square footage. Commercial and industrial units can remove up to 160 pints, while most residential dehumidifiers remove up to 70 pints. Some industrial dehumidifiers units can only remove 50 pints which is similar to a residential unit but they are more heavy duty and will last longer. Commercial and industrial dehumidifiers can reach a variety of square footage so make sure both the square foot coverage and pint size fit your needs when choosing a dehumidifier.
Size – Commercial vs Residential dehumidifiers
On the other hand, commercial or industrial dehumidifiers are often bigger and heavier, though still portable. Usually, they have a higher capacity than residential dehumidifiers and high moisture absorption rate. Depending on a consumer’s preference, or the environmental conditions where it is to be used, one can choose between an industrial dehumidifier made from heavy-duty plastic or steel.
Residential dehumidifiers are generally smaller, lighter in weight and portable. They are often designed to remove moisture within limited spaces, and therefore their capacities are usually low. Additionally, they are relatively quiet while operating and have a stylish outlook, which can complement your décor in the living room or any other room for that matter.
Coverage and how can I calculate how many cubic square feet my room is?
Using a tape measure or ruler, measure the length and width of the room. Multiply the length and width numbers to get the room’s square footage. To get the cubic feet square footage, you measure the height of the room and multiply that by the square footage.
Capacity – Commercial vs Residential dehumidifiers
Generally, industrial dehumidifiers have larger capacities. Some are designed with capacities of up to 280 PPD while most residential dehumidifiers have sizes ranging between 40-60PPT.
Moisture removal capacity of dehumidifiers is measured regarding pints of water it can remove within the 24-hour duration. While purchasing, you may realize their capacities are indicated as 70 PPD for example. That means that the dehumidifier can remove 70 pints of water per day.
Water storage – Commercial vs Residential dehumidifiers
This is perhaps the biggest differentiator between the two classes. Commercial models come with hoses to pump the water through the machine to an outside source such as a drain or just to the outside. Most residential machines have a storage container that can be emptied when they get full. Commercial dehumidifiers are designed to run continuously without having to empty a reservoir every few hours. It is possible to purchase your own hoses to hook up to most residential machines, which essentially converts it into a lower capacity commercial unit, but why would you? A little planning ahead of time could save you time and money.
After a leak or flood, which is better – Commercial vs Residential dehumidifiers?
If you’ve had a leak or flood it’s important to act quickly. The first 24-48 hours are vital in preventing mold and bacteria from growing. After removing the water from the area, using a fan to dry the residual moisture can be too time consuming. That’s where a commercial or industrial dehumidifier comes in handy. They can remove deep imbedded moisture from wood flooring, wall frames, and other hard surfaces more quickly and efficiently.
Not only will they speed the drying process, but it will inhibit the growth of mold and prevent a musty smell from developing. In order for the dehumidifier to work optimally, it’s important to keep the windows and doors closed during this process. Most commercial and industrial units have wheels so you can easily move it from area to area and remove moisture where needed. If you live in a flood area, commercial and industrial dehumidifiers are a great investment to save you time and money after a flood.
Commercial vs Residential dehumidifiers – which is good for home?
Yes, as long as you don’t mind their rugged exteriors. Both commercial and industrial units are made to reduce high levels of moisture and can be used interchangeably, as well as inside the home depending how much square footage you want to dehumidify.
Commercial and industrial dehumidifiers are good for large residential spaces in humid climates. There are units designed for specific places in your home including crawlspaces, pool areas, basements, and garages. Commercial and industrial dehumidifiers will reduce mold, condensation dripping from pipes or windows, and eliminate musty smells. Just like with residential dehumidifiers it’s important to know the size of the space you are trying to remove moisture from. This will help you choose the best unit for your needs. If you plan to use one of these units in your home, be sure to check the product description since some of the industrial and commercial models require special outlets or voltage.
What is my recommended ACH?
ACH is air changes per hour, which tells you how many times the air should pass through the dehumidifier each hour. This will help you determine the airflow needed to properly dehumidify the area. Here are the recommendations based on humidity levels:
- Extremely Wet:
Humidity levels are between 90%-100%, you can see large puddles or have standing water. The recommended ACH is 6. - Wet:
Humidity levels are between 80%-90%, the area has visible stains, wet spots, mold, and mildew. The recommended ACH is 5. - Very Damp:
Humidity levels are between 70%-80%, the room has visible moisture on walls or floor and a mildew smell. The recommended ACH is 4. - Damp:
Humidity levels are between 60%-70%, the area feels damp and smells musty in humid weather. Typical for basements and crawlspaces. The recommended ACH is 3.

AlorAir is one of the top brands when it comes to commercial dehumidifiers. Their best unit – according to specifications – is the AlorAir Sentinel HDi90. It’s a mid-sized unit with 90 Pint AHAM capacity that has two distinct advantages:
- High energy-efficiency (2.88 L/kWh). Energy-efficiency of commercial dehumidifiers ranges from 1.5 L/kWh to 2.9 L/kWh. 2.88 L/kWh is extremely close to the pinnacle of energy-efficiency.
- Build-in pump (convenience). It cannot be understated how a commercial dehumidifier with a built-in pump can ease your life. The build-in pump is the key ‘set it and forget it’ feature.
At tighten humidity levels of 60% to 80%, the AlorAir Sentinel HDi90 will extract about 90 Pints (or 11.25 gallons) of water per day. Using the built-in pump, you won’t need to install gravity drainage or mess around with a bucket. The built-in pump automatically pumps the accumulated water outside.
At extremely high humidity (ideal conditions for any commercial dehumidifier), the AlorAir Sentinel HDi90 can extract 198 Pints or almost 25 gallons of water from indoor air per day.
You can see that the wattage needed to power AlorAir Sentinel HDi90 commercial dehumidifier is low – only 640 W. Coupled with the high energy-efficiency, that means this unit will pump out a large volume of water at a very economical electricity expenditure.
Being a mid-sized commercial dehumidifier, the AlorAir Sentinel HDi90 can cover up to 2,600 sq ft. It doesn’t have a superb airflow, however, with 210 CFM maximum airflow. The noise level for that airflow is 58 dB – quite high for a 210 CFM airflow dehumidifier.
An additional feature that not many dehumidifiers include is the HGV system. HGV defrosting stands for Hot Gas Valve; it’s a defrosting system that enables the AlorAir Sentinel HDi90 to work at extremely low temperatures (36°F). This makes it perfect for cold and damp basements.
High-end specifications with a standard price for a commercial dehumidifier make the AlorAir Sentinel HDi90 one of the best choices. Especially the high energy-efficiency will be responsible for saving up electricity while running.

The BlueDri BD-BD-130-BL is a portable commercial dehumidifier with a maximum capacity of 225 Pints or more than 28 gallons per day.
If you look at its specifications, you should immediately notice it’s enormous airflow. In fact, with the 410 CFM airflow, BlueDri BD-BD-130-BL surpasses all other industrial dehumidifiers. But at what cost? As a general rule, higher airflow comes with higher noise levels. The decibel levels are not included in the specs; however, it’s safe to say this is one loud dehumidifier designed for commercial purposes.
It has an AHAM capacity of 105 Pint; essentially, in a normal above-average humidity environment, the BlueDri BD-BD-130-BL will pump out more than 13 gallons of water per day. That makes it one of the most capable industrial dehumidifiers you can buy.
For such a superior airflow, the BlueDri BD-BD-130-BL has a solid energy-efficiency factor of 2.41 L/kWh. It’s surprising to see such a high energy-efficiency for a dehumidifier designed specifically for industrial purposes.
The consequence of being an industrial-specific dehumidifier are the ‘Pack of 4‘ and ‘Pack of 8‘ packages. For a big warehouse, you will probably need several industrial dehumidifiers. You can buy a pack of 4 or 8 BlueDri dehumidifiers to create a truly powerful accumulated airflow and total capability to extract more than 100 gallons of water per day.
