XL7000

The Best Under the Sink Water Filtration System

Choose this filter if you want broad spectrum filtration + bacteria reduction, along with the added values of a high flow rate, maximum cartridge longevity, and simplicity of installation.
The XL7000 is designed and NSF certified for a flow rate of 2.5 gallons / minute. This allows you to install the XL7000 directly into the cold water line inside your kitchen cabinet, so that all water on the cold side will be filtered to bottled quality.

Most flow rates from a kitchen tap are in the 1.5 - 2.0 GPM range, so the XL7000 can handle the full flow easily. You may also direct the XL7000 through a separate faucet. When the flow rate is less than 2.5 gallons/minute, you can expect even higher quality water than its NSF rating.

CX9000

Excellent value for lower cost

Choose this filter if you are looking for the highest value/price ratio. We want professional, high-quality filtration to be available to as many people as possible. The CX9000 is the perfect choice to make a dramatic difference in drinking water quality when cost is a vital factor.

The CX9000 is designed and NSF certified for a flow rate of 0.5 gallons/minute. It should therefore be used with a dedicated filtered water faucet.

TX9000

Maximum protection against Volatile Organic Compounds and Trihalomethanes

Choose this filter if you are in an environment where you need an unusual degree of protection against a very broad spectrum of possible VOC's (Volatile Organic Compounds), and flow rate and cartridge longevity are secondary concerns.

The TX9000 is designed and NSF certified for a flow rate of 0.5 gallons / minute. It should therefore be used with a dedicated filtered water faucet.
