High-quality carbon filtration provides cleaner water straight from the tap.

During the lifecycle of a single filter, you can save up to 16,000 plastic bottles from being deposited in landfills.
Cleaner Water Straight from the Tap
The Watts CT-1 effectively removes sand, silt, sediment, and rust from your drinking water. It also reduces the taste and odor of chlorine, so you can enjoy water straight from the tap and save yourself the expense of buying bottled water.

Portable and Easy to Install
Installing the Watts CT-1 is a breeze. The unit occupies a small area on the countertop beside your sink, attaching to the faucet by way of a diverter valve. Installing the CT-1 is so easy that most users can filter their tap water in a matter of minutes. The quick installation also means that the CT-1 can be moved from sink to sink with ease. In particular, users of campers or RVs will appreciate the simplicity with which the unit can be moved from one place to another.

Universal Parts for Easy Replacement
The CT-1 accepts all Watts standard 10-inch replacement filter elements. So when it's time for a new filter, you can rest assured that you'll find all the right parts.

The Importance of Drinking Clean Water
Water is critical to proper food digestion, kidney health, brain function, blood health, joint functionality, and more. It's important to make sure that the water you drink is devoid of contaminants. Thankfully, using a Watts water filtration device will ensure consistent quality for all of your drinking and cooking needs. In fact, when you use Watts' high-quality certified water treatment devices and filters, your water will be free of chlorine taste and odors, particles, and many other contaminants that can be detrimental to your health.

*Please refer to the Performance Data Sheet for the complete list of claims for which this system is certified.

An Choice
Not only is the CT-1 filter a healthy choice for you, but it's also a healthy choice for the environment. This filter helps you minimize the harmful environmental consequences of buying bottled water. Incredibly, if a mere ten percent of North America's bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:

  • 133,000 trucks driving an average of 500 miles--saving nearly 12 million gallons of diesel fuel
  • Over 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually
  • 213 million pounds of PET--equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%

Depending upon which Watts water-filtration product you use, you can prevent up to 16,000 half-liter bottles from being deposited in landfills--all in the time it takes to use and replace a single filter.

The Watts Premier CT-1 Counter Top Water Filtration Device is backed by a one-year limited warranty.
