We bought this to replace a Culligan water filter system that we purchased at a home improvement store. this is a far superior system. The water tastes even cleaner than bottled water. Plus the faucet flow is much greater. The price was slightly more than the other system but if I bought this the first time, I would've saved myself from the expense and inconvenience of replacing the low quality Culligan system.
Set up was super easy, it was as simple as in the instructional video for me. We had the same plumbing. We have one in our kitchen and one in our main bathroom. Our water went from chlorine tasting and brown-ish with tanins, to cryastal clear and so fresh tasting. Our city also has lead issues, so my family can now safely drink as much water as we like.
Pros: Clean taste, Clear water, Durable, Easy to clean, Easy to install, Long lasting filter
