* Actual performance depending on site conditions. Please use MEGA’s software to determine actual performance data. If a system with MPure™ stacks is not connected directly to the outlet of an RO system, e.g. after an RO permeate tank, a particle filter (0.5–1 μm, absolute) shall be installed at the inlet of the MPure™ EDI system.
