About PuRO Twist

PuRO Twist is a brand of water filtration systems that are designed to remove impurities and contaminants from drinking water. The company offers a range of products, including countertop and under-sink filters, and replacement filters for these systems. PuRO Twist's filters are made with a variety of materials, including activated carbon, ceramic, and KDF (Kinetic Degradation Fluxion), which work together to remove impurities and contaminants from the water. 

Activated carbon is a porous material that is highly effective at removing impurities and contaminants from water. It works by adsorbing (or binding) impurities and contaminants to its surface. Ceramic is also used as a filter media in PuRO Twist's filtration systems, it is a filter medium that can filter out particles as small as 0.2 microns, and it also can remove bacteria, viruses, and protozoa.

KDF is a type of media that is composed of copper and zinc. It works by creating a redox reaction with impurities and contaminants in the water. This reaction results in the removal of impurities and contaminants, as well as the production of beneficial minerals such as zinc and copper ions.

PuRO Twist's filters are designed to be easy to install and maintain. The company provides detailed instructions on how to install its filters, and they also offer a variety of replacement filters that can be easily swapped out when they need to be replaced. The company also stands behind the quality of its products by offering a limited warranty on all of its filters.

Overall, PuRO Twist's water filtration systems are designed to provide clean and safe drinking water for homes and businesses. The company's use of high-quality materials and their attention to detail in the design and manufacture of their products make them a popular choice among consumers. With a wide range of products and replacement filters available, PuRO Twist makes it easy for customers to find a solution that fits their specific needs.
