9-Pack CPAP Filter, Universal Inline CPAP Filter Compatible with BiPAP Machines ResMed,Dreamstation Standard, Any CACP Machine Size 22mm and 25mm Tube

I am shocked at the performance of this product.My machine has a filter, but a second one would offer better protection from the air I'm breathing, and the price was reasonable.I got a really big surprise when I changed this filter about four to six weeks later. My room is well-ventilated and the home is relatively smoke-free. After viewing the used filter the question arises “ Is our home as ventilated as I perceived it to be?“.

The type we use for ventilators in the hospital is the same. The Sleep Apnea physician was reassured that it does not interfere with the airflow pressure settings.

Fit perfectly on my cpap hose and has little to virtually no restriction of airflow, so your machine should not need any adjustment.

These didn't work with the water in my cpap as it kept blowing off. However, when I don't use the water it works fine.

So far so good. I need to use them over a few months to say definitely. It appears to be a good price for the price.

Easy to install and works well

Perfect fit!!!

So far so good. No instructions came with but thankfully there was only one place it would fit . LolIt fit readily and there is no leaks so I feel like I’m doing as much as I can to filter the air.Again, just guessing, but I assume I should change it out maybe once a month I didn’t find any instructions on that either.
