PurePro M800 direct flow reverse osmosis: a tankless under-sink water filter with a pump, up to 1.2 L/min and tool-free cartridge changes.

The PurePro M800 direct flow reverse osmosis system (M800 DF) is a 5-stage under-sink unit in a compact housing that produces drinking water on demand, without a tank. It delivers up to 1.2 L of water per minute, and the built-in pump allows operation even at low mains pressure. Cartridges are replaced without tools. According to the seller, the unit is fully assembled, 100 % factory tested and sterilized, and made by the American manufacturer Pure Pro.

With conventional reverse osmosis you wait for the tank to fill; with the PurePro M800 direct flow reverse osmosis system, pure water flows as soon as you open the tap. Without a tank, water is also less likely to stand in the system for long. It takes up little space under the counter, measuring 41 cm high, 30 cm long and 25 cm wide.
In the PurePro M800 direct flow reverse osmosis system, water passes through these stages:

The high-pressure pump raises the pressure at the membranes, so the system works at an inlet pressure of 1 to 7 bar. This is an advantage in houses and apartments with low pressure. A 220 V power supply is required. If you are looking for a cheaper tankless system, see the direct flow reverse osmosis 200 GPD, and for a smaller system with a pump and tank, the PurePro M500P or the PurePro EC105P.
