Assessing breathing-system filters.
An assessment of 104 different breathing-system filters has been published by the United Kingdom's Medicines and Healthcare Products Regulatory Agency. Filtration performance was measured by determining the penetration of sodium chloride particles. Wide variations in performance were found. This rapid, easy assessment technique could be used to test each filter during manufacture.
