About this model

This is an adaptation for the Löwenstein CPAP/APAP family. The template and creator of this wonderful design of the Resmed S9 Filter Adapter can be found here: I first used this adapter on my ResMed S9, but after switching to the Löwenstein A20, I made the necessary adjustments. Thanks again to Monroe Williams (TheObstacle) for the work and the great job. You can buy the filters on Amazon: 3M 2135 P3R
