Steris A1501E Replacement Chemical Sterilant Prefilter Cartridge "A" System 1E

Steris A1501E Replacement Chemical Sterilant Prefilter Cartridge "A" for Steris System 1E

• Model: A1501E
• Filtration Rate: 2.5 Micron
• Intended Use / System: Designed for the STERIS System 1E liquid chemical sterilant processing system; used as a prefilter in either a single prefilter arrangement or as the “Filter A” stage in a dual-prefilter configuration.
• Overall Length: 10 inches

The Steris A1501E “A” prefilter cartridge serves as the first line of defense in the sterilant circulation path of the System 1E liquid chemical sterilant system. Before the sterilant fluid (e.g. peracetic acid / hydrogen peroxide combinations or other liquid agents) enters downstream filters, valves, or delivery components, it passes through this cartridge to capture suspended particulates, debris, or precipitates. By removing these larger particles early, the cartridge helps protect more sensitive downstream components (e.g. fine filters, pump heads, tubing) from clogging, wear, or performance degradation.

In a facility that uses a single prefilter configuration, the A1501E handles the entire particulate load prior to downstream processes. In a dual prefilter setup, this cartridge is installed as the “Filter A” stage—handling the bulk of particulate load, while a secondary “Filter B” further polishes the sterilant stream. This staged approach extends the usable life of downstream filters and helps stabilize system performance by balancing particulate load across multiple filter stages.

From an operational standpoint, the A1501E must be replaced periodically—according to maintenance schedules or when pressure drop across the filter reaches a threshold—ensuring consistent flow and sterilant efficacy. Because the cartridge is non-sterile supply (i.e. not delivered sterile) and does not contact sterile instrument loads, its function is strictly internal to the sterilant circuit. Using a proper OEM cartridge like the A1501E helps maintain system reliability, ensures warranty adherence, and supports consistent sterilization results by preserving fluid cleanliness and system integrity.
