Great alternative to buying cases of water and hauling them up a flight of stairs every week. The system took a few hours to assemble and install, and it's actually easier than I thought it'd be. I'm glad I bought it. Great product. If I relocate, this system is going with me. Happy customer.

After having this product for nearly 3 months I can say that this has been a great investment. The installation wasn't super easy but it also does not require a degree in rocket surgery. The installation is somewhat time consuming and does require some patience.

This is the high flow version of a less expensive model. 1 to 1 waste water is nice. The taste of the water is outstanding to me. Have been on some of the best tap water supplies, well water and not so good tap supplies. The re-mineralialization cartridge leaves a pure tasting water, almost sweet, with no after flavors. I bake bread in quantity & I see a big difference in rise and general fermentation from the Zero water filter I was using.

Well they say our bodies are composed of 60% water so I figured my family and I deserve the best drinking water possible. This is my third RO system. I first had the ecowater RO system (3 stage), and the iSpring RCC7AK (6-stage) RO system. The 3 stage was just OK but I wanted a system that would replace the healthy minerals that most ROs take out of the water and the iSpring RCC7AK did just that. Now we upgraded to the PH100 and couldn't be happier. Same great tasting healthy water, and at a 1:1 ratio it is one of the most efficient RO systems on the market. Treat you and your family to healthy great tasting water and give it a try today! Don took great care of me and answered all my questions. There is a great install video online as well. I was a little disappointed the automatic cutoff switch did not match the tubing size but Don assured me they could send me one when it becomes available as it is a new system. After having experience with all three systems this one is by far the highest quality. Watch the video don't get hung up on the manual when trying to install it!

My water here is terrible. I have 1528 ppm in my natural water. My water softener system gets it down to 853 then their reverse osmosis system works fantastic and gets me down to 324 ppm. It is not expected to do that well on horrible well water like mine, and I am very pleased it accomplishes this much. I would highly recommend their product, and their service department is so easy to get a hold of and helpful that if you have questions or issues it is a phone call you don't mind making.

Great system, make sure you order the correct replacement filters, as these are a different size than previous versions due to the large tubing.

While making plans for our new construction house I was looking for a RO system that could be installed in the garage and piped to the kitchen sink and the refrigerator. After looking at many brands and many models it was obvious the PH 100 was the best choice. Don Huie at ispring was very helpful and recommended that I use a pump to boost the water pressure on the outlet side of the PH100 in order to have good pressure at the sink and refrigerator. The aquatic aquajet model 5853-GE12-V81D variable speed pump is delivering great pressure. The entire system piping is 3/8 RO tubing which also helps with good pressure. I was impressed with ease of installation and start up with no problems. Just follow instructions and you can expect great results. Only one word of caution, the installation instructions that came with my system did not mention that the filters for stages 1, 2 and 3 must be removed from the filter housing and remove the shipping wrappings. We now have great tasting water, crystal clear ice cubes and a very efficient system only one gallon of waste water for each gallon of drinking water. I highly recommend the PH100 .

Seems to be one of the best system with a 1:1 cleaned to waste water ratio. It is more expensive than others with worse ratio, but considering saving natural resources, didn't mind to spend the extra money. Device looks a good build quality, provided instructions (printed, web, videos) are good for setting up the filter. Though the printed/web/video resources are not necessarily consistent so iSpring need to update&sync the resources. It does not decrease the rating of my review and could start using the filter without, but a pair of quick fitting was missing from the package so could not install the shut off vale right away. On the other hand Customer Service was reacting friendly and quickly, got the missing item a week later.

I like the taste and and the cost if very fair for the filter. Only one complement is that you can only fill a gal jug and have to wait for the pressure tank to refill. I have the 100, which says it should give me 100 gals per day. It will not.

I have a distiller but making a few gallons at a time can become annoying, not to mention cleaning up the pot can be really time consuming if plenty of deposits built up inside of it. of A!!!! I have been drinking various bottled waters for years and years, and this system outdoes them all!
