Description
The PulmoGuard II Filters carry the original line forward with a fit aimed at more instruments. SDI states the design goal plainly: all the benefits of the first generation, plus a fit on many PFT instruments without an adapter. Ten configurations cover filter only packs and kits with mouthpieces and noseclips.
About These PFT Filters
Pulmonary function testing expels bacteria and viruses under pressure, and this filter family holds a 99.999 percent cross contamination efficiency against that exposure. The second generation keeps the pleated media and transparent, inspectable housing of the original design. Its distinguishing change is fit: the housing is made to seat on many PFT instruments directly, with no adapter in between. A group of configurations is built around a 1 inch O.D. mouthpiece for instruments and setups that call for it. Kit versions add The Klip noseclip or a Comfit disposable mouthpiece so the box covers the complete per patient arrangement.

- Faster room turnover – adapter free seating shortens the reset between patients
- Documented protection – 99.999 percent cross contamination efficiency is the figure infection control asks for
- Mouthpiece coverage – the 1 inch O.D. configurations serve setups the standard mouthpiece does not, a differentiator within the family
- One box setups – kits with noseclips and mouthpieces cover the patient arrangement from a single pack
