  • Remember to replace your Reusable Nebulizer every 6 months!  

    To take the hassle out of remembering, PARI Vios 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 Vios compressor comes equipped with a small, bright 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 (# 041E4851) may be purchased directly from National Allergy Supply.
