- Purchased this filter as a Christmas present for my parents who live in a chlorinated water town after being fed up with buying gallon jugs of water. Brita filters don’t generally filter out chlorine/chloramine from the water, hence why we had to buy jugs of water. This model has the specific chloramine filter included which works really well! The sink faucet was very easy to install, I ended up using my own PEX tubing instead of what was provided but I’m sure iSpring’s lines are perfectly fine. Would recommend to anyone looking for a non-electrical, under the sink water filtration system that won’t break the bank.
