Sylvane has been working with customers for over 20 years assisting them in resolving air quality problems. High-capacity dehumidifiers are used in a wide variety of commercial and industrial applications, including indoor growing. For efficiency and durability in this tough environment, the Quest 335 High Efficiency Dehumidifier is one of our top recommendations.
This unit is one of the most efficient, high-capacity dehumidifiers available, with versatile installation options, easy access for serviceability, and can also be ducted if necessary for the situation.
How Sylvane Reviews Industrial Dehumidifiers
Industrial dehumidifiers have many different features and methods of installation that make them ideal for specific uses. We consider several of these factors when reviewing any of these rugged machines and take into first consideration the intended uses and adaptability for those applications, as well as other key characteristics.
- Where It Can Be Used: What is this industrial dehumidifier designed for, and where is it typically used?
- Efficiency and Moisture Removal Capacities: While total dehumidification capacity is important, it’s just as key to understand how the dehumidifier performed at various temperatures?
- Placement and Installation Options: Does the dehumidifier need to be professionally installed? Where can it be installed, and how hard is it to set up?
- Controlling The Dehumidifier: How is the unit controlled? Does it require additional controllers or is everything you need included with the product?
- Air Filtration: Does the dehumidifier have the ability to provide clean dehumidified air to your space?
- Cost: Is the cost of the dehumidifier worth the investment as compared to similar products?

Where to Use the Quest 335 High Efficiency Dehumidifier
Engineered for growers of commercial cannabis, the Quest 335 is newly redesigned for greater performance and efficiency, able to handle the heavy workloads of large grow houses.
And, because it can be ducted, it is also effective in storage areas, retail spaces, schools, and multi-family homes and residential communities.
Efficiency and Moisture Removal Capabilities
With its multi-coil design, the 208-240-volt unit can pull up to 335 pints of water per day and AHAM, with an efficiency of 9.3 p/kWh. At 75 degrees Fahrenheit and 50% RH, it operates at 6.2 p/kWh removing up to 230 PDP.
The 277-volt model can remove up to 350 PPD with an efficiency rating of 6.13 p/kWh.
Placement & Installation Options
The versatility of installation is one of the features we believe makes this dehumidifier ideal for indoor growing spaces. It can be set up as a freestanding unit in spaces as small 3 x 4 feet, or it can be suspended overhead using a hang kit. We like that it can even be ducted from a remote location to the grow room.
There is also the option of either 208-240-volt power or 277-volt power. Both come equipped with a 10-foot power cord and plug, and are simple to install.
Designed with access and top panels which are easily removed, even when suspended, in-field maintenance tasks are also simplified.
Controlling the Dehumidifier
The Control panel of the Quest 335 was found to be very intuitive and easy to use. It is equipped with an on-board humidistat which can be used to program a desired RH level, and the fan speed set to high or low.
It also has an automatic setting which activates the Filter-life compensation mode. This is a proprietary technology which ensures a consistent humidity level. At the core, a pressure switch is connected to the variable fan setting. When a change in pressure is detected, the fan speed is slowing increased to maintain the desired CFM airflow.
Air Filtration
Another compelling feature of this industrial dehumidifier is its MERV-13 filter which comes standard with the unit. Working with the Filter-life compensation technology, this filter captures a high rate of particulates without interfering with the overall CFM airflow. We noted that this sets it apart from most other comparable units on the market.
Cost
While the Quest 335 High Efficiency Dehumidifier carries a not insubstantial price-tag, its effectiveness and reliable durability proves worth the investment. Not only useful in grow houses, we can also recommend it as an excellent choice for military storage areas, automotive industry and shops, schools, restaurants, and houses of worship.
Quest dehumidifiers have been the preferred choice of indoor growers for years, with their high-efficiency models bringing greater benefits in terms of cost savings. The Quest 335 is the most efficient dehumidifier currently on the market, and it is also California Title 24 compliant for both freestanding and ducted installations.
Backed by a full 1-year, and component 4-year warranty, this powerful, efficient dehumidifier is an efficient workhorse worth the cost.
The Bottom Line from Sylvane
With its money-saving high efficiency, filter-life compensation technology, ease and versatility of installation and maintenance, we confidently recommend the Quest 335 industrial dehumidifier for commercial growers, as well as a wide range of other industrial applications.
