Frequently Asked Questions

What are Whatman 1820900086 microfiber filters used for?

These binder-free glass microfiber filters are primarily used for personal air sampling and airborne particulate monitoring. They are commonly installed in personal air samplers to capture aerosols and dust for gravimetric or environmental analysis.

What is the particle retention of the GF/A filter media?

Grade GF/A filters typically provide approximately 1.6 µm particle retention, offering an effective balance of fine particle capture and high flow rate for air monitoring applications.

What material are these filters made from?

The filters are manufactured from high-purity borosilicate glass microfiber without binders, which minimizes extractables and supports reliable analytical results in air sampling and laboratory workflows.

Why are binder-free filters preferred for air sampling?

Binder-free construction helps reduce background contamination and sample interference, while also providing high loading capacity and fast airflow—key advantages when measuring airborne particulates accurately.

What equipment is compatible with the 3.7 cm (37 mm) format?

The 37 mm size is widely used in standard personal air sampling cassettes and monitoring devices, making these filters suitable for occupational hygiene studies, environmental monitoring, and industrial air quality testing.
