Are before-and-after photos from the same place and conditions?
An impression is not a measurement, and the company does not offer one as the other.
The Terms of Use state: “A reported result describes only what the identified test found.” The Validation page names each report and certificate in its tested and certified list by institution and number, lists the pathogens and the conditions tested, and reports its field observations separately from its laboratory testing, describing the site and the period for each and naming the monitoring system used. The label for the NanoFlashing™ Air Filter states: “Results in a building depend on the system, the airflow, and how well the filter fits its track,” and: “It works alongside ventilation and cleaning, not in place of them.”
A change a person notices in a room can have several causes, and a record that does not name its conditions cannot be read against one that does.
