Good taste easy to install
7 Stage Undersink RO Water Filter System | Hydrogen Alkaline pH 8.5–10 | PFAS Fluoride Removal | WaterMark Certified
Does the job
When I first bought this system (4 years ago) the replacement filters cost $50...now they cost $200. Do not buy this product due to overpriced filters (of which you HAVE to replace).
THE PRICES WERE GOOD, I RECOMMEND THIS SERVICE
Great value filters-just keep buying off Shield. Thx.
Purchased whole hose filter system with cover, took a while to work out the instructions but after that install was very easy
So far product is working great
Highly recommend for cost effective water filteration system
After having this installed a few months ago I must say this is an amazing product and great value. The water is crystal clear and tastes like water should.
Easy to install and water pressure is perfect for my use. Thanks again, one very happy customer.
Was easy to install, this is our 2nd filter in another house, very pleased with the end result
Very happy with the system. Turned stained colored water to crystal clear water.
Highly recommend
