Solid carbon blocks are one of the most effective and widely used technologies in the Point Of Use (POU) drinking water treatment industry.  Solid carbon blocks, or simply carbon blocks, are employed either as standalone treatment methods or in conjunction with other filtration technologies.  While seemingly simple at first glance, there are many factors to evaluate when designing and manufacturing an efficient carbon block water filter. This comprehensive guide addresses key considerations a buyer should evaluate when designing a carbon block filter and selecting a supplier.

A high performance carbon block filter is the predictable end result of combining comprehensive product planning, proven production methods, and effective quality control throughout the manufacturing process. Multi-Pure International’s wholly-owned manufacturing subsidiary, Carbon Block Technology (CB Tech), consistently produces the highest performing solid carbon block filters available in the market today. Such consistency is a direct result of the company’s tightly controlled product manufacturing process and the quality assurance protocol followed from beginning to end.  This paper outlines the quality assurance plan that Multi-Pure and CB Tech follow to ensure final product quality.

The focus of this paper is on identifying the standards that apply to the products that are commonly utilized for treating drinking water at the point of use, and on what is behind the standards that make standards compliance so important. This paper also outlines the testing process employed by the recognized leader in testing for the water filtration industry, NSF International. Finally, it describes how a leading drinking water filter manufacturer, Multi-Pure International, employs standards compliance to help consumers evaluate and compare the company’s products to competitive alternatives.
