LGR 3500i Dehumidifier
Controls moisture in large areas

The 3500i delivers the maximum moisture pulling capacity in a highly portable unit. Its built-in humidistat enables moisture control in spaces up to 17,000 cubic feet. It’s an LGR or low-grain refrigerant unit, so the 3500i keeps drying when humidity levels drop to dry more thoroughly.
