If a shop says active ingredient, is it naming a substance or using loose marketing language?

The company describes a physical property, and it does not describe the filter in the language of a chemical product.

A charge is a physical property. It is not a substance or a mixture of substances. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The filter is supplied as a finished article; it is not a substance and it is not a mixture. A shop that says “active ingredient” is not using the company's words: the company's position is that the filter incorporates no substance to act on harmful organisms, and it contains no active substance. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller.
