These testers quantify a fabric's ability to capture airborne particles, a requirement for respirators, surgical masks, HVAC filters, and industrial filtration media. Generating calibrated aerosols and measuring penetration via photometric or laser particle counters, they support EN 149, NIOSH 42 CFR Part 84, and ISO 16890, delivering the lab-grade data needed to back filtration claims in regulated markets.
