CPAP Filters Compatible with BiPAP Machines ResMed, Dreamstation Standard, Any CACP Machine Size 22mm and 25mm Tube, High-Efficiency Filtr-ation & Clean Air &Enhanced Comfort CPAP Inline Filter

Breathing so much better since I started using this attachment

Simple installation . They work . Have used them for years .

I feel much better about adding these to the hose on my machine to help keep the pollen out of my lungs. I don't feel the small filter on the machine is enough to help keep the pollen out of my lungs. I have been sleeping a lot better. I highly recommend these to everyone using a CPAP machine.

Work well with my cpap machine

The filter fits onto both hose lines easily. I deal with a lot of pain so I don't sleep in one position all night. For this reason, I have found the filter to be a bit bulky because it gets in the way. I'd rather keep it connected here to know I'm getting the best protection. I clean my hose but let's be honest, we can't scrub all those nooks and crannies 100% clean. I would rather move the hose and notice a difference when I wake in the morning...a difference in allergy relief. My lungs and throat no longer hurt when I wake up in the morning. I will continue to use these filters!

Good piece of equipment for health.

I use the Resmed Air Sense 10 thus, the filter can only be connected at the end of the heated hose just before it connects to my mask making it extremely uncomfortable to sleep with. You could connected at the back of the CPAP machine but being I used a heated hose for the humidifier that negates the connection at that location. I also, reduces the air flow to the point where the machine will automatically try to readjust your working pressure; my machine went from 13.4 to 15.6. I also received the warning on my RESMED app on my phone telling me my working pressure had been automatically readjusted due to a restriction to the flow of air. I have been using a CPAP for 14 years and had never had this issue, the moment I connect this filter and use it for a month my machine starts acting up. Furthermore, the filter does not last the 30 days prior to needing to be replaced.

Works great
