Great Water® Undersink Filter Systems are a natural choice whenever a sink or faucet is being replaced. A little bit of plumbing will result in a permanent built-in upgrade with only simple (usually once a year) filter changes.

Undersink Dual Stage Drinking Water Filter– Metered
Our Price: $109.00

Neatly tucked under the sink, this 2-stage unit is made in the USA 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.
Undersink Triple Stage - Metered
Our Price: $139.00

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.
These industry standard 10" filter housings use the same high quality cartridge media as the Great Water® counter top units. You should be reminded however, that while these units are quite simple for a handy person to install, they do require an additional countertop hole to accommodate the faucet. Instructions for drilling are in the installation section, but if it is through a stone countertop, we recommend a professional.
An easier way is to replace your old faucet with a model which has an integral spray attachment, and place the filtered faucet in the extra hole left by your old hose and spray.
