Directions for Use:

Please see the Owner's Manual tab for full instructions on the PARI Trek® S Portable Aerosol System that comes with the PARI LC® Sprint Nebulizer.


  • Remember to replace your Reusable Nebulizer every 6 months!  
  • To take the hassle out of remembering, PARI Trek S comes equipped with a visual indicator called Timestrip® that monitors the time lapsed from the first treatment to 6 months. The Timestrip is easy to activate and read. The visual display will boldly read "NOW" when it's time to replace the nebulizer. No more guesswork or calendars needed.

  • Filter Replacement:
  • The PARI Trek S compressor comes equipped with a small, white air filter to keep dust and other particles out of the device. This filter is designed to last for up to 500 hours of use. Over time, it will turn grey and require replacement. A good rule of thumb is to replace the air filter every 6 months - at the same time you replace your PARI nebulizer.

    Never wash or reuse the air filter, and replace immediately if it gets wet or clogged. Genuine PARI replacement filters may be purchased directly from National Allergy Supply.

This is by far the BEST nebulizer product I have ever used! I have used many over my years of having a lung disease and would never use anything else now. The time to get the medicine into system is excellent and the machine is so convenient that I don't have to worry about having an attack while out shopping, sporting event, etc. This machine allows a better quality of life overall due to the convenience and dependability.
This product is easily accessible and not bulky.
I purchased this compressor in 2005 from this site. The 3 year warranty replaced my first compressor when it died. The replacement just died and of course this time the warranty had expired. I purchased a new one, but not from this site. I found the same compressor on [URL] for [$]. I don't understand how there can be such a price difference between the 2 sites. I also saw it for cheaper prices on other websites. Do some price shopping before you purchase.
I love it
