Over time, lint builds up in your dryer vent system causing reduced airflow and increased back pressure. This reduced air flow results in longer drying times, higher utility costs and an increased risk of a dryer fire. The LintGard measures the back pressure caused by lint build up in your dryer duct. As the pressure increases, the gage oil moves up the scale (measured in "inches of water column"). Once the oil moves into the yellow or red zone, it's time to clean your dryer vent. It requires no electricity or battery power to operate so you can enjoy years of trouble free operation while safely monitoring your dryer's operation.
