The Ecowater
ERO-375 is part of the
Water Filters test program at
Consumer Reports. In our lab tests, Reverse Osmosis Water Filter
models like the ERO-375 are rated on multiple criteria, such as those
listed below.
Flow rate:
how long it took to filter one quart of water
Efficiency:
the percentage of incoming tap water that actually becomes purified drinking water, or the ratio of purified water to feed water. A 25% recovery rate means that for every 4 gallons of water that enter the system, one gallon is filtered for you to drink, while 3 gallons go down the drain as wastewater.
Clogging:
reflects how the time to filter increased over the lifespan of the filter
