Our city water wasn't too bad, but we still want better and safer water for drinking. Instead of buying bottled water, we needed to purchase a water filter system. After some research, we decided to purchase the Ispring system. This systems is 3 stages and seemed to be great product with high rating and good reviews. We installed Ispring in the basement. Our friend bought a similar system called Apec. As per his introduction, his Apecs feed water adapter was more complicated, came with a plastic faucet, and they are not using john guest fitting like they claimed. Our Isprings feed water adapter was very easy to install, has clear housing on first stage, came with a metal faucet, and it came with many blue clips to lock the connectors in place. It took our friend a little more than an hour to install their Apec system , our Ispring, however, took us less time. Overall, we like Isprings system better because of the clear housing, extra securing blue clips, better faucet and faster water production speed. We really recommend this water system to anyone who want better and safer drinking water.
