Determine which Dehumidifier to Use

Dehumidifiers ate tool that simply remove water from the air. Much like any other tool, there are situations where a dehumidifier will work well, and other times when a certain technology would be inefficient. General Guidelines.

LGR:  Low Grain Refrigerant.

Use in most residential / small commercial situations.
Good for warm/high humidity conditions
Adequate for drier conditions down to 34 gpp

Portable Desiccant:

use for difficult to dry situations, such as difficult class-4 losses.
Use if a structure cannot be warmed to a temperature where LGR's would be effective.

Conventional:

Use for simple/small losses.
