Nispira CPAP Inline Filter Viral for BiPAP CPAP Machines ResMed, Dreamstation Standard Tubing Outlet 22 mm Machine Outlet 25mm, 12 Packs

Good inline solution to add more filtration to CPAP Works well. Affordable

Easy to use and almost scary how much dirt the collect before it gets to my lungs. I didn't realize there could be so much dirt given my cpap also has a filter.

works well and less expensive to but in bulk

It works on my husband's machine and regular tubing, but does not work with my RESMED Air Sense 10 with heated tube and humidifier or my mask. Will fit on the machine, but cannot connect the heated tubing. Will fit on the other end of the heated tubing, but does not fit on my mask's tubing. The end is the same size as my pillow mask's tubing. Needs an adapter which does not seem to exist.Keeping them for my husband to use.

Update: I have been using these in line filters on my CPAP for about 5 months and they catch dust that would otherwise have gone into my lungs. When I replaced the filter with a new one it is good to see the color difference between the two filters. The new filter is bright white and the month (sometimes month and a half) old filter is a dingy gray color from the dust it catches. Nothing major like you see in a furnace filter but definitely a change in color. So I know I’m not breathing that all in night after night. Will continue to purchase this product.

Great product and great prices

Wow these really do filter out the dust and debris. I had no idea what I was breathing in from my CPAP machine.

I have been using them for sometime. My question is why does the machine filter not get dirty but this one does. I change it every month. The dirty side is coming from the air out of the machine. How and why doesn't the machine filter catch anything? I have the ResMed CPAP machine
