Filter Table

We have worked with experts within the filter industry to produce the presented data below. These are some of the filters typically found in medical institutions and can be integrated into the Pneumask assembly. The filters below have been ranked according to their filtration method, if they have a heat and moisture exchanger (HME), if they are intended to be placed at the patient-Y or the expiratory limb of the circuit, and their viral filtration efficiency (VFE). Preferred filters are highlighted in darker shades of green and less preferred filters in lighter shades of green (in terms of their capacities for extended use). A detailed discussion of variables to consider when selecting a filter can be found here: https://www.pneumask.org/filter-selection-guidelines.

Note: Bold text indicates the filter has been approved by the FDA for extended life when used in their original application as a breathing circuit filter (EUA granted).
