Does the buyer's alleged loss arise from the claim or from a separate installation problem?

Does the buyer's alleged loss arise from the claim or from a separate installation problem?

The company does not give legal advice, and it does not comment on how a claim would be decided.

The Terms of Use state: “A reported result describes only what the identified test found.” They also state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.” They also state: “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.”

What can be checked on any filter is the charge. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request. The label states: “Results in a building depend on the system, the airflow, and how well the filter fits its track.”
