Taste-wise, the water comes out clean and neutral, which makes a difference when making coffee or tea, since there’s no lingering chlorine smell getting in the way. I’ve been using it regularly for cooking, washing vegetables, and keeping a pitcher in the fridge, and nothing about the performance has dropped off so far. It’s also nice that it sits neatly under the sink and doesn’t crowd the cabinet space, so everything stays organized. My wife uses the filtered water daily for meals and hasn’t mentioned any odd taste or smell, which is usually a good sign in our house. It’s one of those upgrades that doesn’t draw attention to itself, but you definitely notice when things just work as expected. Read more
