The A1562 “B” prefilter cartridge functions as the secondary or polishing filter in a dual-prefilter arrangement, downstream of the “A” filter (pre‑filter “A”). While the “A” filter removes larger particulate load from the sterilant or rinse water stream, the “B” filter further refines the fluid by removing finer particles, suspended debris, or precipitants that escaped the first stage. In systems where water purity is critical (such as in endoscope reprocessing or high-level disinfection circuits), this helps protect delicate downstream components (valves, tubing, pumps, sterilant injector nozzles) and ensures consistent sterilant or cleaning solution delivery without clogging or performance drift.

In practical use, the fluid (sterilant, rinse water, or other process solution) flows first through the “A” cartridge. After that, it then passes through the A1562 “B” filter before entering critical fluid paths that supply the instruments or reprocessing chambers. This staged filtration helps maintain lower particulate load, steady flow, and minimal pressure drop, extending the life of more delicate filters or system parts. Because the B cartridge is finer (0.1 µm polishing), it catches smaller particles that could otherwise degrade performance or introduce micro‑contamination risks.

Replacement of the A1562 is part of routine preventive maintenance; when pressure differential across the cartridge builds (indicating clogging or loading), or at scheduled intervals, the cartridge is replaced to restore optimal flow, reduce back pressure, and maintain system reliability. Being a returnable OEM part encourages proper maintenance cycles. In sum, the Steris A1562 “B” prefilter is a critical component in ensuring fluid cleanliness, system durability, and reliable performance in sterile processing or endoscope wash systems where liquid chemical sterilants or high‑precision fluids are used.
