The advantages of an under sink water filtration system.

Find out if an under sink filtration system is right for you by checking out these key advantages to having fresh, filtered water from your kitchen sink or dedicated faucet.

  • Water pouring into a glass with ice.
    Quality water at the center of it all.

    An under sink system helps reduce contaminants right at the tap or a dedicated faucet to deliver cleaner, clearer water for drinking, cooking, making coffee, ice, tea or other beverages.

  • A man installing an under sink filtration system.
    Easy installation.

    Systems can be installed in under an hour without, in most cases, the need to cut pipes or to shut off the water to your entire house.

  • A person rinsing a vegetable in a sink.
    Conveniently accessible.

    Enjoy fresh, filtered water at the most central point of most homes—the kitchen sink. Cartridges are easy to access, making changeouts fast and easy.

  • A hand touching an under sink filtration system.
    Compact size.

    Under sink systems are designed to fit in tight cabinet spaces without taking up too much room and the replacement cartridges are typically smaller than whole house system cartridges.


Easy to install. Easy to maintain.
