2 Packs Replacement Tube for N20, 2 Packs Replacement Short Tube Compatible with N20, Avoid Leakage and Reduce Noise，Great Value Supplies by Medihealer.

Fits my N20 perfectly!

Good fit with my mask and as the description provided. Work well with my mask

Update: my first review indicated the hoses were noisy. Tonight I finally decided to dig in and see if I could fix it. Lo and behold I figured out there was a tiny tear in the very thin silicone seal on the nasal mask where the hose clips in. It was this tear that was noisy, not the hose. My bad! I replaced the nasal mask and it seems better. Duh!(Old review) I ordered this despite some reviews that said it was noisy. Mine are as well. The value and quality seemed good (2 short hoses per package), but the seal at the swivel creates a hissing sound when not exactly aligned. It doesn’t wake me up but it does annoy me when I’m trying to fall asleep.I wish to heck someone would make one of these that has a better diffuser (and doesn’t hiss). Like the original equipment tube, it blows a pretty good stream of air straight out, which means I have to sleep with my back to my wife. I affixed another brand’s diffuser to the outlet and it worked great without killing me with co2 poisoning, but it really didn’t stay put so I gave up. Can’t be that hard. Help?

3.5 ratingRight away I liked the construction of the product. It fit perfectly and has a great snap in to the mask. The bad is that it doesn’t seem to seal completely so if there is slight pressure or tension you can hear it. Not a huge deal but the actual resmed products seem to not have this issue. Great price and if you don’t mind the slight air leak noise, it’s perfect. It doesn’t affect the functionality, just something I’ve noticed.

I should have known better, buy cheap - get cheap! They look fine in the package, but both hoses straight out of the bag didn't connect well to the mask. It immediately had an audible leak unless I used my hand to push it in and hold it at a weird angle. If this was QA'd at all, I'd be amazed. Terrible fit and finish.

Great product.

This design is very good and is better than the original tubing that came with my system. High quality and no whistling noises! Very happy with this product and I highly recommend it to others.

I habe been a cpap user for 20 years and also in the industry for 15 yrs so I do have indepth knowledge regarding cpap eqquipment. I decided to give these a try because I needed it quickly. I wouldnt say it is horrible but i also cant say its great either. Thankfully it came w 2 hoses because tje first one only lasted about a month before it started leaking at the snaps near the exit ports. It is also considerably longer than my pre ious one from the brand manufacturer. I didn’t think it would be a big problem but it was somewhat annoying. Maybe it would have taken some time to get use to but that hasnt happened. It is a good back up unit but I dont believe i wipl ise it as a primary piece.
