Frequently Asked Questions

Do I need both a dehumidifier and air movers?

Yes, and they are not interchangeable. Air movers accelerate evaporation by pushing high-velocity air across wet surfaces, which pulls moisture out of carpet, subfloor and drywall into the room air. A dehumidifier then removes that moisture from the air. Run air movers alone and you raise the humidity until evaporation stops; run a dehumidifier alone and moisture leaves the materials far too slowly. IICRC S500 drying is built on both operating together.

What size dehumidifier do I need for water damage?

Size by AHAM pints per day against the affected area, not by the saturation figure manufacturers prefer to advertise — the two can differ by more than double. As a working guide, 30–40 pints suits up to 1,500 sq ft that is only damp, 50 pints a moderately wet space of that size, and 70 or more for larger or persistently wet areas. If the space runs cool, the low-temperature rating matters more than capacity, because a standard unit loses output below about 65°F.

Is an LGR dehumidifier worth it for a homeowner?

For an active water damage job, yes. LGR — low grain refrigerant — units keep removing moisture at the low humidity levels that occur late in drying, which is exactly when a standard dehumidifier gives up. That is the difference between reaching dry standard and stopping at 'feels dry'. For ongoing basement humidity control rather than an active loss, a good purpose-built basement unit is the more sensible purchase.

Can I use box fans instead of air movers?

For comfort, yes. For drying structure, no. A box fan moves a large volume of air slowly around a room; an air mover delivers a focused high-velocity stream along the floor and wall surface, which is where evaporation actually happens. The airflow pattern matters more than the raw volume, and it is why restoration crews use air movers rather than the cheaper fans.
