High-Filtration Efficiency Without Sacrificing Resistance
The AFt36 bacteriological filter provides a high degree of protection for the subject, while its low resistance allows for accurate testing results.
This pulmonary function filter is highly effective and easily surpasses published ATS recommendations for flow resistance in pulmonary function instrumentation, which suggest resistance should be below 1.5 cm H2O/L/sec at flow rates of 14 L/sec:
MRI Use: MR Safe (see Specifications for components)
AFT36 replaces the AFT13 filter with paper mouthpiece.
