When you purchase a gallon of gasoline for your car in the U.S., are you confident that you actually receive what you pay for? Looking past the question of product quality, how do you know how much gasoline was added to your fuel tank? You know because you purchase gasoline using a uniform standard of measure, the U.S. liquid gallon, established by a governmental entity, the National Institute of Standards and Technology.

Furthermore, you rely upon another governmental entity responsible for local enforcement of weights and measures to regularly inspect the vendor’s gasoline pump to make certain that precisely a gallon of fuel actually is pumped on demand. Standards and, equally as important, testing against those standards, are key to consumers being confident that they are receiving what they are paying for.

The application of standards and testing is just as important in purchasing drinking water filters and delivery systems. It is the only objective means for a consumer to validate a drinking water system manufacturer’s product performance claims. There are innumerable drinking water filters and systems available in the market, and conclusive product test results support the consumer’s ability to evaluate and differentiate among them.

Product testing conducted by a reputable and independent third-party testing laboratory is the only way to ensure unbiased test results. However, in the complex sciences of chemistry and toxicology that are applicable to evaluating the quality of drinking water, awareness of the details behind the test results is critical to truly understanding a product’s capabilities. You cannot simply rely upon seeing a recognizable logo; you must delve deeper.

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, Carbon Block Technology, employs standards compliance and independent testing to help consumers evaluate and compare the company’s products to competitive alternatives.
