DEHUMIDIFIER Comparison

Ideal Level of Dryness

For most homes, a relative humidity level of 50-70% ensures comfort. However, the ideal level can vary based on individual preferences.

Dehumidifiers come with a margin of error in their readings, typically ranging from 5-15%. Keep in mind that these scales are relative.

Several factors influence humidity levels, including the room size, the items being dried, and the air refresh rate, which depends on how much outside humidity enters the room. Time also plays a role in achieving the desired dryness.

Low Grain Refrigerant vs. Desiccant Dehumidifiers

For low temperatures or focused drying, desiccant dehumidifiers typically perform better. However, at higher temperatures, desiccants can still offer advantages.

Refrigerant dehumidifiers, on the other hand, tend to struggle when operating above 35°C (95°F), as the compressor, which is the heart of the system, faces excessive strain. The compressor drives the gas around the refrigeration circuit, and prolonged operation at high temperatures can shorten its lifespan.

Considerations for Restoration Professionals

LGR (Low Grain Refrigerant) dehumidifiers are simple to operate—just place one in the room, switch it on, and let it pump the water away automatically.

Desiccant dehumidifiers, however, typically deliver faster drying times and allow for better control and direction of dry air. They also offer the advantage of being highly durable and requiring minimal maintenance, making them a reliable choice for demanding restoration environments.
