The filter system for which I purchase these filters is a fabulous value. The water tastes great, a lot of impurities are removed, and the system fits in the small cabinet under my kitchen sink. If you don't have room for/can't afford a reverse osmosis system, this is the way to go.
2 adults & 4 dogs all drink filtered water. Based on my research, this unit is tops in filtration and safety. Great guarantee and excellent filter replacement system- shipping and installation.
Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter
Couple comments: 1) It's not always easy to install, depending on the configuration of your existing sink. I had to replace my faucet because I couldn't detach the sprayer, and I needed the sprayer hole for the filter dispenser. It took my quite a while to get it all sorted - I'm not that handy - but I did get it done myself and it doesn't leak, so that's saying something. 2) My sprayer hole is on the right side of the sink. The handle to turn the filter dispenser on and off is on the left side of the dispenser. It would be more accessible if the dispenser handle was on the right side. Seems good overall. Definitely saving me time, trouble and money as I used to lug in 5 gallon containers multiple times / week. It's taking more time to save money because I had to replace my sink faucet.
