Conduct PFT using a disposable barrier filter
The MicroGard® pulmonary function testing (PFT) filter acts as a barrier to viral and bacterial cross-contamination.
U.S. kit options
II B kit – Oval filter with nose clip
II C kit – Round filter with nose clip and rubber mouthpiece
II C filter – Round filter
The MicroGard II filter is well balanced between optimized filtration efficiency and minimal resistance (Delta P) to airflow.
MicroGard filter options are competitively priced.
The MicroGard II filter has gone through full verification and validation with Vmax®, Jaeger® and Micro Medical equipment.
The filter material consists of polymer fibers that do not promote the growth of mold, mildew, other fungi or bacteria.
The PFT filter material resists degradation over time and withstands extreme temperature and humidity.
