In this blog, we have covered the rigorous protocol set by the Environmental Protection Agency (EPA) for a product to make public health claims, that is, for a product to be described as protecting public health. These are products like disinfectants, HVAC filters, water treatments, and copper-infused biocidal surfaces such as EOScu and copper alloys. For everyone else, there is the "treated article" category which only allows products to be described as protecting the product itself from mold, mildew and odor-causing bacteria. However, consumers will often see in marketing materials that a product passed "JIS Z 2801" or "ISO 22196" or "ASTM E2149" tests with a percentage reduction in bacteria. In today's post, we'll look at what those tests measure and how they do not meet the rigor demanded by the EPA (and why marketing materials may try to imply that these tests are the same!)
