Commercial Dehumidifier Sizing Calculator

Record every input with its source and date. Humidity changes with weather, operation and time of day, so one reading should not be treated as a permanent load. Compare exact product performance at representative temperature and RH.

Before purchasing, verify electrical service, drain route, clearance, air distribution, operating range, filtration, service access and warranty. Use a qualified professional when the project involves fixed wiring, HVAC ducts, contaminated water, structural drying or code requirements.
