Respirator Breathing Circuit Filter Efficiency

Respirator Breathing Circuit Filter Efficiency

The Respirator Breathing Circuit Filter Efficiency test is used to compare the filtration efficiency of breathing system filters (BSFs) intended for healthcare facilities. The test is performed in compliance with ISO 23328,  EN 13328 and ISO 23328-1, “Breathing system filters for anesthetic and respiratory use. Part 1: Test method to assess filtration performance.”  Nelson Laboratories has extensive experience testing filters and other filtration devices.

Study Outline

The Respirator Breathing Circuit Filter Efficiency test evaluates BSFs in the “unused state” and “after conditioning.” The conditioning apparatus exposes the filters to humidified air to simulate a period of clinical use prior to filtration efficiency testing. Conditioning is performed for 25 ± 1 hour. The BSFs are evaluated at flow rates of 30 or 15 liters per min, based upon adult or pediatric intended use.
