  • Viral & Bacterial Filtration Efficiencies of over 99.99+%
  • Quick & Simple to Install and Replace
  • Allow for Bi-Directional Airflow
  • Low Resistance to Gas Flow means that you keep the strong airflow you've come to expect from your CPAP/BiPAP machine
  • Sonically Sealed -- No Chemical Adhesives

The Inline Bacterial Viral Filter is easy to install and should not require re-calibration on most CPAP machines including those from Respironics, ResMed, Fisher & Paykel, Puritan Bennett, and DeVilbiss. Simply attach it to your machine between the air outlet and your standard CPAP/BiPAP tubing. After that, turn on your machine and experience a steady flow of clean, pure, good tasting air.

The Inline Bacterial Viral Filter's naturally hydrophobic filter allows maximum filtration with a minimum loss of air flow.

Usage Information: Bacterial Viral filters last on average 4-6 weeks however your filters may last longer or shorter. In general BV filters should be changed whenever the filter material looks dirty.

Usage Notes: Some users find that using In-Line Bacterial Viral Filters can reduce pressure and therapy effectiveness in humidified CPAP/BiPAP machines. Use of Inline Bacterial Viral filters may adversely effect auto sensing on Auto-CPAP machines especially at low pressures (below 7cm).

    I was really surprised as to how light the filter was, it works great and will probably be ordering more soon, but am getting new machine and want to make sure it will work on it. Thank you
