Are you ready to roll up your sleeves and make a difference? Filter Builds - Spring 2026 is just around the corner, and this year, we’re thrilled to deepen our partnership with 20 Liters—a remarkable organization born out of Mars Hill volunteers in 2007! Since then, 20 Liters has dedicated itself to bringing clean water to communities most in need. This hands-on event is your chance to be part of something big—help assemble water filters, connect with passionate people, and learn about life-changing solutions. Come out, build filters, and build hope. Save the date—this is a spring event you won’t want to miss!
