The world of greenhouse humidifiers is fairly small one, but that doesn’t mean you don’t have choices. There are a number of excellent options available. We’ll outline several in order to help you make an informed purchasing decision. The best of the best, in our opinion, is the Quest Dual 205 Overhead Dehumidifier. We’ll explain why we think so, just below.
Top Pick for Best Dehumidifier For Greenhouse
The Quest 205 Dual is the largest dehumidifier for a greenhouse on the market. No job is too big for this machine to handle. It can remove an impressive 205 pints of water per day, making it capable of being used as a commercial greenhouse dehumidifier. The best part is that it only uses 13.2 amps/115V of power, making it an extremely efficient option. Other features include:
- Automatic restart.
- High-efficiency filter.
- 5-year warranty.
The best part? It’s made in the USA!
Pros and Cons
The best thing about the Quest 205 is that it is designed and optimized for low heat load. This allows it to control humidity even in cooler, humid environments. A close second is the fact that it is an overhead unit. It doesn't take up valuable floor space. A third consideration worth mentioning is the fact that the unit is "plug and play". There’s no additional duct work or other installation required. Simply plug it in, and turn it on. The machine does the rest. You can buy duct work separately if you want or need it.
The only major drawback with the unit is its price. It is the largest greenhouse dehumidifier on the market. Its hefty price tag reflects its sheer size and capabilities. This, however, is definitely a case of getting what you pay for. A simply excellent machine all around. Well worth your consideration.
The Dri-Eaz Revolution LGR F413 Dehumidifier
The DriEaz Revolution LGR Dehumidifier is lightweight and compact. Despite its small size, it can draw moisture from a space as large as 7,000 square feet. Designed with portability in mind, you can easily move this unit from one location to another (see video below). Convenient if you're dealing with excessive moisture over a very large area.
Pros and Cons
Its small size and portability are both a pro and a con. On the one hand, if and when you need to move it, that’s very easy to do. On the other hand, though, those same features mean that it just can’t extract moisture at the same rate as fixed-position models. Even so, depending on what your specific needs are, this is (or could be) an excellent choice. Its small footprint means it won't take much floor space. That's handy, but still not as good as an overhead model.
The Ideal-Air Dehumidifier
This unit offers a good blend of functionality and portability. It has a fairly small footprint, being much taller than it is wide. It is also mounted on wheels, making it easy to move from one location to another. In addition, it has impressive moisture extraction capabilities, able to handle up to 180 pints a day for a fraction of the cost of the Quest.
Pros and Cons
The major downside to the unit is that while it is plug and play, it lacks an onboard humidity controller. If you want one, you’ll be buying that separately. Added to that is the fact that the fan is only single speed. It only has one mode of operation, which makes it somewhat less versatile overall.
Nonetheless, it is an excellent choice for anyone looking for a solid rate of moisture extraction while retaining ease of mobility. A solid dehumidifier for greenhouse use.
The Ebac CS60 dehumidifier
The Ebac CS60 dehumidifier is designed for quiet, efficient operation. It will serve you well if your moisture extraction needs are fairly modest. The unit is capable of extracting up to 56 pints of moisture from the air each day. It also comes equipped with an adjustable humidstat, allowing for completely automated operation.
Pros and Cons
Quiet operation tops the list of the attractive features of this unit. You'll also be pleased with the fact that there’s nothing else to install. Like the Quest, it is plug and play. It also comes with a washable air filter which can be used again and again. Finally, there's the matter of price. This, however, is a bit of a blessing and a curse. The reason? At least some of the machine’s low price takes the form of a smaller capacity. The fact that it can only handle 56 pints a day of moisture extraction means that it may not be the ideal choice for especially humid environments. Not recommended for large greenhouses.
So what’s the Best Greenhouse Dehumidifier?
The Quest Dual 205 dehumidifier is by far the best machine overall. Its impressive feature set and massive moisture handling capability makes it simply unparalleled. Excessive moisture can be a real problem, and not just in greenhouses. If you have a nasty moisture problem to contend with and are desperately seeking a solution, the Quest is the machine you want, unquestionably.
