New standards change filtration requirements

With filters being exposed to a much broader range of particle sizes, which requires higher levels of filtration maintenance, filter technology manufacturer Freudenberg Filtration Technologies (FFT) says attention should be drawn to the new ISO 16890 standard for filter testing and assessment. With the new standard, implemented at the end of last year, filter efficiencies will be determined with regard to the particulate classes PM1, PM2.5, and PM10, says FFT MD Andrew Hersey.
