The patented EcoSmart Filter is the first filtration system to economically address the challenges of harmful sprinkler system runoff. Compact, portable and highly effective, the EcoSmart Filter employs a series of filters designed to reduce contaminates that are destructive to our environment. It is by far the most effective Best Management Practice (BMP) available today. The EcoSmart Filter latches onto the external sprinkler pipes of a building. Water flushes from the building and flows into the EcoSmart Filter, where it funnels through a series of three separate micro filters.
