I bought my faucet about 3 months ago, because the water in my apartment smelled heavily chlorinated. The Faucet came with multiple attachments, to ensure it would fit onto my faucet, which it did very easily. All I had to do was soak the actual filter for 15 min before putting it into the place where the filter is housed, and it was ready to go. I noticed immediately that the cholorine smell was gone and my water tasted so much better. I also have the option of turning on and off the filtered water and the tap water, so that Im not wasting the filter for things like doing the dishes. I love this faucet and I know its time to replace the filter, because the light on the front went from green to red.
