Understanding Our Technology
How Our Dehumidifiers Operate
1
Step 1: Air Intake
Moist air is drawn into the dehumidifier through a specially designed intake system, ensuring efficient moisture capture.
2
Step 2: Ionic Membrane Action
The air passes through our proprietary ionic membrane, where moisture is effectively separated and removed.
3
Step 3: Dry Air Release
Once dehumidified, the dry air is released back into the environment, maintaining optimal humidity levels.
