          great under sink water filter
          bought it from homedepot. arrived as advertised. installed quite easily. i did tighten the filter housing too much such that when i went to remove then for filter replacement, the wrench provided with the kit broke. I contacted Mayra at iSpring and they sent me a new wrench at not cost. I finally got the housings off and filter replacement was a jiffy. the water has a flavor when the filers are new. this last a couple days maybe, but after that it's great tasting water.

            Who knew you could have Smart Water at home?
            I've never been a huge water nerd but now I'm preaching to everyone about this product. I got tired of buying bottled water and this thing produces WAY better quality than anything I've had before. The company is fantastic as well. I called with a small issue and other questions and Sean there helped me out immediately. When was the last time you called a company and talked to a real person immediately? Huge shout out to the company. Up next, a whole house filter!

              Totally Satisfied
              I ordered this water system through Home Depot Canada online. It was shipped directly from the iSpring facility in Georgia USA within 2 days of the order being placed. Arrived at my home amazingly fast. I bought this system to replace a 20 plus year old system that had started giving trouble. Since I have never liked the taste and scale of municipal water I wanted to continue to have an in home water treatment system. This one is very similar to the one it is replacing. We really like the tap that came with it. The push to connect water tube fitting made installation quick and easy. We also have water from this system plumbed to the refrigerator (water tastes great) and the humidifier on our furnace to avoid mineral deposits on the drum and inside the furnace. I installed the system in the basement laundry room hanging from the floor joists. I am totally satisfied.

                Amazing service at a fraction of the cost.
                I purchased this filter for drinking water and an aquarium mixing station. I have looked at a few companies and iSpring had amazing technical support answering all of my questions about my configuration. It was great to get this level of support when the filtration system is a fraction of the cost when buying it from a hobby store. iSpring is my source for all my water future filtration needs... Thank you Don for your all of your help.

                  Add pressure in water tank to boost water flow
                  iSpring 6-stage water filtering system is a great product. I can save a lot in buying bottle water, and save a lot of plastic to protect our environment. I can have a good quality and a good taste of water anytime I want without going to the markets to buy bottle water. In the long run, iSpring water system can save us much money to have a good quality of water, save us energy to haul water and save the environment by minimizing the use of plastic.

                      Good taste
                      5 years ago I bought the ISpring 6-stage filter system at Home Depot. It includes an alkaline filter to raise the PH. The water tastes good and the cartridge replacements have been easy to order. Also there is an excellent manual that is helpful. I am glad I purchased this product.

                        Clean Install, Excellent Documentation
                        The instructions are very clear as are the installation videos on YouTube. I installed the RO machine head on a sliding panel to make it easier to change cartridges later. Definitely fill/drain the holding tank twice to get to the good water. All the parts (plus spares) were easy to identify and install.

                        Overflow valve goes bad, starts leaking
                        The valve on this unit went bad, started putting water in my lower cabinet. Contributed to water damage in my floor. I contacted manufacturer for a replacement, he said he would send replacements. He never did send after a follow up. $200 system swamped out my cabinet (no warning these go bad, manufacturer said they do) and its useless to me now because i cant get part
