Can accumulated dust shield the underlying surface property?
Heavy dust loading and a used filter for one year are among the conditions the material was tested under.
The Terms of Use state that a reported result describes only what the identified test found, and that each scientific or technical result must be read in light of its test conditions and qualifications. The Validation page names the conditions the material was tested under, including heavy dust loaded, fast air flow, a used filter for 1 year, after 60 washes, after 2 years of storage, and after 60C for 64 days. What the company states about a named test is the institution, the report number where the report carries one, the date, the standard where the report names one, the article tested and the result, with what that result does not establish.
The company publishes no separate measurement of the charge under a dust layer; the charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
