Who This Is For
- You are adding dedicated dehumidification because moisture spikes during the dark cycle are risking your crop health.
- You are upgrading to industrial gear because residential units fail under the 24/7 stress of a sealed grow space.
What We Found
- The dark mode lets you check settings during sensitive dark cycles without worrying about light leaks.
- The stainless steel cabinet holds up much better in high humidity environments than standard painted steel units.
- Using MERV 13 filters is a huge jump from the mesh screens that usually let dust and spores through.
What Users Say
- Owners of compact rooms say this unit fits into tight corners where full scale industrial models will not work.
- Operators who switched from home units say their power bills dropped because this pulls more water for less energy.

FAQs
The Quest 100 is specifically engineered for space-constrained applications. With compact dimensions of 24" W x 14.5" H x 6" L and weighing only 60 pounds, it fits where other commercial units can't. Despite its small size, it delivers a powerful 100 pints/day capacity, making it perfect for small grow rooms, curing areas, and processing rooms.
M-CoRR™ (Multi-Coil Refrigeration Recovery) technology uses an advanced multi-coil design to recycle heat during the dehumidification process. This allows the unit to achieve its 100-pint capacity without overworking the system, resulting in an exceptional 7.5 pints/kWh efficiency while consuming only 540 watts. This means lower energy bills and reliable long-term operation.
The Quest 100 offers two primary installation configurations for maximum flexibility. It can be used as a freestanding unit placed on the floor with the included leveling feet, or it can be suspended overhead to save valuable floor space using the optional Quest 100 Hanging Kit.
