Buying Guide

How to pick the best commercial dehumidifier for you

When selecting the best commercial dehumidifier for you, it’s important to consider two main things: location and how often you plan to use it.

Each of the dehumidifiers on this list covers distinct areas. If you’re searching for something to put into a crawl space, you’ll need a smaller dehumidifier with a large tank. It’s also useful to have a remote control if your dehumidifier will be somewhere that’s hard to reach.

Alternatively, if you’re using these products in large rooms where you can change the tank easily, then size won’t matter. In those scenarios, opt for a larger scale dehumidifier with an enormous tank, so you won’t have to change it frequently.

How many pints should a dehumidifier hold?


The answer to this question will depend on your needs. Some smaller tanks on the list can only store 55 pints. However, that’s enough for around 24 hours of continual usage. Anything 55 pints or over should work for you.

Do all dehumidifiers work in every room in your house?

Yes! Dehumidifiers are built to work in enclosed spaces, regardless of if they’re damp, wet, dry, or cold. No matter where you put these products in your house, they’ll dehumidify your room.

What size dehumidifier should you buy?

The size you need will depend on where you want to use your dehumidifier.

If you’re going to be using it in your home, like in a bedroom or bathroom, then you won’t need a large humidifier. A humidifier that stores 70 pints, or even slightly less, will still run for 24 hours.

If it’s somewhere accessible, like your bedroom, you’ll also be able to empty it without much effort. So, a smaller storage tank is completely fine because you can drain it when necessary.

However, if you’re using the dehumidifier in a huge area or somewhere hard to access, then you may want a larger tank. That way, you can run the dehumidifier for days at a time without needing to touch the tank. This is especially helpful in tight spaces because you can turn the dehumidifier on and forget about it.



This list includes the five best commercial dehumidifiers you can find. From dehumidifiers for huge spaces, to those that fit in crawl spaces, you’ll be able to find the perfect product for you. We’ve included a range of sizes and key features, meaning there’s sure to be something you’ll love.

If we were to pick just one commercial dehumidifier on this list, you can’t go wrong with the BlueDri DB-76. With 150 liters of storage, you’ll be able to set this dehumidifier up and forget it. It’ll work in the background, making sure your room is always exactly how you like it.
