Neatly tucked under the sink, this 3 stage unit is made in the USA to the same rigid specifications as the 2 stage with an integral patented flowmeter to measure the actual gallons passing through the filter. Never wonder when to change, this unit features auto shutoff at change time. If you have a basement or utility room, the Great Water® undersink filter can be conveniently located anywhere within 40 feet of the faucet.
