The Takeaway:
1. Our Pick: Quest 2015 Dual Dehumidifier
2. Runner-Up: DRI-EAZ Revolution LGR F413 Dehumidifier
3. Budget Pick: Ideal-Air Dehumidifier
The world of greenhouse humidifiers is fairly small, but that doesn’t mean you don’t have choices. There are several excellent options available.
We’ll outline several 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.
Our Pick: Quest 2015 Dual Dehumidifier
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:
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 that the unit is “plug and play.”
There’s no additional ductwork or other installation required. Simply plug it in, and turn it on. The machine does the rest. You can buy ductwork separately if you want or need it.
The only major drawback of 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. It is simply an excellent machine all around. Well worth your consideration.
Runner-Up: DRI-EAZ Revolution LGR F413 Dehumidifier
The DriEaz Revolution LGR Dehumidifier is lightweight and compact. Despite its small size, it can draw moisture from 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. On the other hand, though, those same features mean it can’t extract moisture at the same rate as fixed-position models.
Even so, depending on your specific needs, this is (or could be) an excellent choice. Its small footprint means it won’t take up much floor space. That’s handy, but still not as good as an overhead model.
Also Great: Ideal-Air Dehumidifier
Our Verdict: This is an excellent product for any family. It’s strong, sturdy, and long-lasting and does the job that it promises.
This unit offers a good blend of functionality and portability. It has a fairly small footprint, much taller than it is wide. It is also mounted on wheels, making moving from one location to another easy. 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 it lacks an onboard humidity controller while it is plug-and-play. 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 operation mode, making it somewhat less versatile overall.
Nonetheless, it is an excellent choice for anyone looking for a solid moisture extraction rate while retaining ease of mobility. A solid dehumidifier for greenhouse use.
Honorable Mention: 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 can extract up to 56 pints of moisture from the air daily. It also comes equipped with an adjustable humidistat, allowing for completely automated operation.
Pros and Cons
Quiet operation tops the list of 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 that can be used repeatedly.
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. It can only handle 56 pints a day of moisture extraction, so it may not be ideal 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 make 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.
