Low-flow showerheads of yesteryear had the spray of a weak sprinkler and seemed to defeat the purpose of saving water because it took so long to actually collect enough water to get clean. Things are different now. Low-flow showerheads can reduce water consumption by up to 50 percent without giving up needed pressure (psi). I have tried a few low-flow showerheads in my life, and while many that fell into that "sprinkler" category, the good ones didn't. My favorite is Moen's Envi showerhead. The flow feels strong and I don't feel like I am missing anything.
What is also important to me is the bigger context of the product and how it's made. Moen recycles more than 90 percent of the materials used in manufacturing, and they are working to create a culture of sustainability within the company, filtering all water so employees are reusing the majority of water used in product testing, ensuring all new products use less water and meet EPA WaterSense guidelines and aren't consuming bottled water.
