Quest makes commercial dehumidifiers for growing, not repurposed domestic units. The difference is capacity at low temperature - a household dehumidifier collapses once the room drops toward lights-off temperature, which is exactly when you need it most. Quest units are rated to keep pulling water at grow room conditions.
- Overhead dehumidifiers: The Quest 70, the compact commercial Quest 100 and the Quest 155 - hung overhead to free up floor space. See all humidity control.
- Air movement: The Quest F9 air mover for shifting air across a canopy - browse circulation fans.
- Control: The DEH 3000R controller for running units to a humidity setpoint - see humidity controllers.
- Filters: MERV 13 filters for the 70, 100 and 155, plus Quest 70 pre-filters - the consumable that keeps capacity up.
- Ducting and mounting: Duct kits, supply and return duct kits for the 155, and hanging kits and brackets for all three units.
Why choose Quest?
Rated capacity at real grow room temperatures. A domestic 20L unit is measured at 30C and 80% humidity, conditions your room never sees. Quest publish performance at the temperatures you actually run, which is why a Quest 70 outperforms a nominally larger consumer unit.
Quest FAQs
Overhead or floor standing?
Overhead frees floor space and puts the dry air above the canopy where it mixes better. It needs a ceiling or frame strong enough to take the weight.
How often do MERV 13 filters need changing?
Depends on room dust, but a blocked filter cuts airflow and capacity sharply - it is the first thing to check if a unit seems to be underperforming.
