I preferred Culligan CuZn, Hydroviv or Waterdrop because it's a well known brand in water filtration that has been around for years is . The filter was extremely easy to install in my 30 inch wide kitchen sink cabinet and took maybe 20 minutes to complete. Luckily no leaks and I had cold water running as instructed within 10 minutes of installation. Only reason for 4 instead of 5 stars is the pressure difference after installation To before and after: - taste and smell: significantly different; In northern New Jersey we have great tasting tap water, although at times it smells/tastes faintly of chlorine. The smell is gone and the taste of the water is even better than before - Clarity: there is less of it; there wasn't a big difference here, but if you look closely, there were fewer floating particles in the filtered water. -Water pressure: The water pressure drop is noticeable, watch the video to learn more about hot and cold. The hot pressure is the same as the cold pressure before installation. We have a lot of water pressure here so the pressure drop is manageable but that is the reason for my 4 star rating. All in all it's a great filter for the price and we'll see how it performs over the next 6 months. On the plus side, at least I haven't had to refill my large Brita jug just yet.
