R.O. Membrane:
The third and main stage of the filtration is R.O. membrane. It is “semi-permeable”, which
means that it allows water to pass through but prevents dissolved particles from passing
through. It splits the feed water into two streams: clean water goes to the post-filter and then
onto the tank and faucet. Waste water with rejected particles goes down the drain.
Post-Filter:
Last stage of filtration is an activated carbon post-filter and/or remineralization for fine con-
ditioning and keeping the extra freshness of your water.

Performance:
Performance of the appliance such as filtered water delivery rate, rejection rate, etc. is highly
dependent on local conditions (inlet water pressure, temperature, TDS and degree of contam-
ination, tank air pressure, etc.) and R.O. system use pattern. Actual performance may vary.

Efficiency rating means the percentage of the influent water to the system that is available to the user as
reverse osmosis treated water under operating conditions that approximate typical daily usage.
