Strengths: Increases humidity in small 8 ft. x 8 ft. room by +/- 5% in dry Nevada 10% ambient air
Summary: The filter plugs with minerals in short time. A sink faucet clearance of over 12 inches is required to fill the water container. Must be inverted to fill. To fill from another container or pitcher requires a major balancing act. Overall not very effective in raising humidity.
