Buying Guide

Thinking about buying a high-quality dehumidifier, but don’t know exactly what you are getting into? Here is some information that might come in handy.

What Is a Commercial Dehumidifier?

heavy duty dehumidifier reviews

A commercial dehumidifier is a unit that was made to remove great amounts of moisture and water from the air. It represents a great option for office complexes or construction sites, where the likelihood of humidity forming is very high.

So, a commercial dehumidifier can significantly improve air quality. Not only will it prevent any risk hazards for your employees, but it will also protect your business from any damage caused by mold or mildew.

  • What are the Differences between Residential, Commercial, and Industrial Dehumidifiers?

What separates commercial and industrial dehumidifiers from residential ones is the fact that the former can handle large spaces, as well as high amounts of moisture in the surroundings. The dehumidification technology they use is almost the same.

A residential humidifier can generally handle up to 75% humidity and regular, seasonal moisture. Plus, considering that it was meant to dehumidify rooms and houses, it might not be able to handle a 4-floor office building, for example.

Commercial and industrial dehumidifiers, on the other hand, can reach up to greater distances – making them perfect for large structures. Plus, considering that they can work with humidity levels up to 95%, they are a great option in case of floods. This way, in the event of a disaster, you can still save your materials and make them reusable.

  • Can I Use a Commercial or Industrial Dehumidifier in My Home?

best commercial dehumidifierThere is no reason why you should not be able to use a commercial dehumidifier in your home. Since most of them have a humidistat that can regulate the temperature, they can do the same work for your whole house as they do for an office building.

The only reason why you might not want to use them for your house is that they are slightly bulkier – and not as fancy-looking. Plus, most of the time, they are unnecessary – unless you have a source of standing water in your house. You can use them – but you don’t necessarily need to. Using one would generally be considered overkill unless you want to dry out a flooded house.

  • How Much Water Will a Commercial Dehumidifier Remove?

This will depend on the model that you go for. You can find units that can extract up to 700 pints of water – or you can stumble upon those that gather up to 160. It is all dependent on your needs. Obviously, the ones with a higher capacity will cost more – so you have to be willing to open up your wallet.

Things to Look for in a Good Commercial Dehumidifier

commercial dehumidifier reviewsWhen browsing for a good commercial dehumidifier, there are several things that you might want to keep in mind. Some factors include the following:

  • Coverage Capacity

How wide is the area that you want to dehumidify? Make sure that the commercial dehumidifier of your choice can cover the entire area of your building. This way, you won’t have to endlessly move it around.

  • Build Quality

Commercial dehumidifiers are generally made either from heavy duty plastic or steel, which make them very durable. However, some low-cost commercial dehumidifiers can be made of lightweight plastic – which you might want to be wary of.

  • Low-Temperature Operation

If most of your work is done in a warehouse, the chances are that the temperatures can be very low during the cold season – but humidity will still be on the rise. Look for units that can work even in temperatures down to 32 degrees Fahrenheit.

  • Pint Capacity

If you own a wide space, you might want to ensure that your unit can extract at least 50-70 pints of water per day. Anything below that is for residential use.  The best 50-pint dehumidifier is generally meant for commercial use.

  • Auto Restart

Do you work in a place that is prone to power failures? In this case, you might want to buy something with an auto restart option. This way, once the power goes back up, the unit will pick up where it left off.

  • Built-In Humidistat

Some dehumidifiers feature a built-in humidistat that will show you real-time readings of the humidity and temperature. If you want to keep a clear setting, look for one that has this option.

  • Automatic Drainage

When you don’t have the time to continuously drain the water tank, drainage is very important. Look for units that have automatic drainage so that you won’t have to do it yourself.

  • Noise Level

Commercial dehumidifiers are generally very noisy – but you can do some research if you want a quieter one.

  • Low Maintenance

Commercial dehumidifiers are, by default, fairly large in size – so you should at least look for options that are easy to maintain. Automatic drainage and removable filters are always a plus.
