Numjaw 10Pcs Universal CPAP Filters for ResMed CPAP Machines, Individually Packing Disposable CPAP Air Dilters, Compatible with 22mm Tubing and 25mm Mask Elbow

My wife and I both use these exterior filters on our claps we recognized better air quality and were amazed how dirty the air was in our clean house. I recommend this produce

At the price and ease of use for any CPAP machine in today's world not having to pay ridiculous markup from provider's is always a plus. Six months is the average life expectancy for the filter, no doubt about it they probably aren't the best ever made but they do filter very well.

I think I like it, but I wonder why it needs to be replaced daily as the original one does not require it

Filters for my CPAP machine. I get less problems and it traps all the allergies. I recommended to my other brother and he loves it too. Thank you for this product and very affordable.

What I got home from the movie, there was no package left at my door.

I was very impressed with how much the filter captured as far as dust. It is really a good thing to have if you have allergies.

Ordered these before somewhere else and the price wasn't the same, also these filters are much more reliable. Thanks for asking.

I feel more secure and safe using these filters.

Good shipping and fast service really needed this thanks

I need to return it doesn't fit wrong size!!
