The automatic backwash on the M-90 from Forsta Filters, allows the filter to clean itself as needed, and requires almost no routine maintenance. A stainless steel body, screen, and components make the M-90 filter extremely durable. The filter has a flow capacity of up to 100 gallons per minute, and screen mesh to 5 micron. The M-90 uses a single 1 inch flush valve and uses less than 2 gallons of water in the 6 seconds backwash cycle.
