Table 2. Efficiency of the test mask without Micro Ventilator for filtration of Staphylococcus aureus and bacteriophage ΦΧ174.
Replicate | % Filtration assessed by infectivity | |
---|---|---|
Staphylococcus aureus | Bacteriophage ΦΧ174 | |
Replicate 1 | >99.9% | 99.6% |
Replicate 2 | >99.9% | 99.8% |
Replicate 3 | 99.7% | >99.9% |
Replicate 4 | 99.8% | 99.8% |
Replicate 5 | >99.9% | 99.5% |
Mean ± SD (N=5 replicates) | 99.8%±0.1%* | 99.7%±0.2%* |
This work was performed by Nelson Laboratories (Salt Lake City, USA). *, For the purpose of averaging and statistical analysis, values indicated as >99.9% were treated as 99.9%. SD, standard deviation.
