A breathing system filter can remain connected to a laryngeal mask airway during recovery from anaesthesia. The Luer‐lock monitoring port on the filter could be used for the delivery of supplementary oxygen. The efficacy of this technique was assessed __in vitro__ by comparing the performance of two

## Summary The filtration performance of breathing system filters can be measured by challenging the filter with sodium chloride particles. However, the challenge itself may alter the filtration performance. This effect was determined by repeating a standard challenge test five times on one sample

The bacterial and viral filtration performance of 12 breathing system filters was determined using test methods specified in the draft European standard for breathing system filters, BS EN 13328-1. All the filters were of two types, either pleated hydrophobic or electrostatic, and these two types di

The ability of 29 different breathing system filters (five pleated hydrophobic and 24 electrostatic) to prevent the passage of water was assessed. Five, 10 or 20 ml of water was added on to the patient side of the filter during ventilation of a patient model with the filter layer orientated either h

The filtration performance of 33 breathing system filters (nine pleated hydrophobic and 24 electrostatic filters) was measured using sodium chloride particles. The particles had a size distribution with a count median diameter of 0.07 ¡m and a geometric standard deviation not exceeding 1.83. The geo
