High-efficiency shower heads are designed to use less water while still providing a satisfying shower experience. They typically limit water flow to 1.5 to 2.0 gallons per minute, compared to standard models that can use up to 2.5 gallons per minute. This reduction in water usage helps conserve resources and can lower water bills. These shower heads often incorporate advanced technology, such as aerators, which mix air with water to maintain pressure and create a fuller spray. By choosing a high-efficiency shower head, consumers can enjoy a comfortable shower while contributing to environmental sustainability and reducing their overall water consumption.
