40 Pack CPAP Filters Premium Disposable Air Filter, Universal Replacement Filter for Resmed Airsense10, Aircurve10, Airstart, Resmed S9 Series CPAP Standard Machines

The great big packages were a bit cheaper per filter, but I was afraid this may be poor quality or not fit correctly.When I received these filters they were great fit, and as good or better quality then the original. It's still a good value for 40 filters. Should last me a long time and no worries about running out for the next 3 1/2 years.

Fits well and performs as described.

Probably the best filters I've tracked down in Amazon. They're not flimsy or look like 1 ply cotton rectangles. For perfect for my machine, but the only issue I have with them is that, they're not as thick as the OEM ones, so I have to use up 2 filters in the slot to make it comprable. See pictures attached. Would buy again.

I have been looking for filters like this for years. My DME provider kept telling me that they provide the best name brand filters that give the best performance. WRONG. They are coarse mesh that never get dirty because the dirt just passes through and into my lungs. A prior company provided filters like this and they will get dirty quickly as they filter very well. These are an exact match and very inexpensive.

I used my first filter from this pack on Tuesday. I was quite surprised on how well they were made. I like them much better than the open weave filters I get from my DME provider. These are much better for catching the dust and allergens that the large open weave filters let through! We live in the country and dust and dirt are a fact of life. I change my filters once a week due to these conditions at home. Now I can get better filters that are cheaper than the previous ones I got. Thanks again for a great product!!

These filters for my C-Pap machine are a great deal, and are just fine to use. I bought two different types and I am pleased with each. It sure beats the option of buying singly for some stupid price each!

After using these for several weeks I have found them to be lacking in the one area they are important: filtration. I swapped them out every week since purchase but got suspicious when none of them came out dirty so I used the same one for 2 weeks which included home use and a camping trip. Pulled it out and it was spotless. With a normal filter I'd pull it out and you could visibly see the dirt and dust in the air being caught. Thought I'd found a viable replacement. On to the next filter

As good or better quality than OEM filters that came with machine.
