PVC Membrane Filters
PVC membrane filters support the analysis of metals, silica, and dust in air monitoring applications. Laboratories and industrial hygiene professionals choose these filters because they deliver consistent performance and reliable analytical results. In addition, PVC membrane filters absorb very little moisture. As a result, they provide excellent accuracy in gravimetric analysis and reduce weighing variability caused by humidity changes.
We produce these filters using high-quality polyvinyl chloride (PVC) combined with a small percentage of polypropylene (PP) binder. This material composition improves mechanical strength while maintaining a uniform pore structure. Moreover, the low ash content allows laboratories to apply multiple NIOSH and OSHA analytical methods without introducing interfering residues.
Because PVC membrane filters show very low hygrophilic behavior, they perform well even in environments with fluctuating humidity. Therefore, analysts can achieve stable pre- and post-sampling weights. Furthermore, the chemical stability of PVC supports efficient sample digestion and preparation, which helps laboratories maintain accurate and repeatable results.
PVC membrane filters meet the requirements of NIOSH Methods 7601 and 7602, as well as applicable OSHA standards. Consequently, professionals frequently use our filters for regulatory compliance and occupational exposure assessments. Additionally, the filters fit standard air sampling cassettes and equipment, which allows easy integration into existing monitoring programs.
Overall, PVC membrane filters provide a dependable solution for air monitoring applications that require precision, consistency, and regulatory compliance. For these reasons, many environmental and industrial professionals rely on PVC membrane filters for routine and long-term sampling projects.
