Virus & Bacteria Filter

Philips Respironics


Masks Size Guide

This in-demand inline filter filters out 99.99+% of bacteria and viruses in the air (including Covid-19). It can be attached to your CPAP and BiPAP machines or CPAP mask to deliver the cleanest, freshest air.  The disposable filter should be replaced weekly (every 2 weeks maximum) to minimize condensation, humidity build-up and ensure the efficiency of the filter.  

More Info

This filter does not affect your CPAP pressure and does not increase resistance to breathing. Attach this filter to your machine between the air outlet and standard tubing to experience a steady flow of completely clean air. If using a heated tubing, attach this filter to your CPAP mask's short tubing or directly to the mask. Using this filter along with the machine's filter increases the defense against air pollutants. This bacteria and virus filter has a universal connection on both ends of the filter container allowing it to work with all brands of machines and well as most CPAP masks. Filters are considered CPAP supplies and are covered by most insurance companies.


Universal ends allow the filter to work with all manufacturer brands of tubing, CPAP machines and most CPAP masks.
