Around the testers sits the cleanroom aerosol toolkit: the shop-listed AG-1800 aerosol generator, aerosol photometers for HEPA scan testing, sampling probes, zero filters, high-pressure diffusers and aerosol diluters — the instruments that challenge filters and prove the challenge was real.

Why integrity testing is a category of its own
Filtration failures are invisible: a nicked membrane passes liquid and looks perfect. Integrity testing converts that hidden risk into a measured result tied to the filter's specification, and the record becomes part of batch documentation in pharmaceutical production.
Bag and glove testing extends the same logic to isolators and containment: the barrier is only as good as its weakest glove, and a pressure-decay test finds the leak before the campaign does.
The aerosol toolkit
HEPA and ULPA verification challenges the filter with a generated aerosol and scans downstream with a photometer; generators, diluters and diffusers make that challenge controlled and repeatable, from room terminals down to compressed-air points. The cleanroom monitoring guide connects integrity and aerosol work to the particle counting programme.
