2 Packs Replacement Swivel Elbow Connector Compatible with F20 and F30,Tube Quick-Release Elbow,Great-Value Supplies by Medihealer

Worked perfectly for my F20 mask. My old elbow failed, making it so my mask wouldn't pressurize - it just noisily blew air out the sides. This elbow fixed it.

Worked exactly as needed. Fast shipping made an emergency situation less stressful.

I tried this replacement as it’s cheaper than ordering through medical supply. Instantly regret that decision. I was confused the first three nights I used this as my water tank would be completely bone dry so much that the smell of plastic being heated up woke me. I didn’t realize the mask leaked air at first. When I put the mask on as I got in bed, my machine starts out with low pressure then gets higher as I sleep. My wife told me it sounds like a lot of air was escaping. Well this morning I woke up because I had to urinate and noticed the sound of air leaking badly. I left my machine on and put my original elbow on (thank god I hadn’t tossed it). I instantly had high pressure and no leaks. Had so much pressure that it was lifting my mask off my face.What a waste of money. Product claimed to have no leaks and fits perfectly. That’s bs. This DOES NOT FIT PROPERLY with my N20. This HAS air leakage.I will be looking for different elbows again. SMH

Works well with no air leaks. Flapper valves function correctly. Hose rotation is less than the original and the connection to the mask is a little finicky. Delivered the next day on a weekend and a great emergency replacement for an original elbow with damaged flapper valves.

They were delivered on time and very happy with product

Cheap, but... cheap. They leak 10 times as much air as ResMed's factory ones do. The leak is loud. I tried tying a cloth around the connection but it doesn't help much. The clips wear out and it starts falling off the mask.

Just like the original. Better priced.

This is not a good replacement for the OEM part. It's not as secure as the original, so leaks air and makes more noise as a result. It's better than nothing, but not worth the purchase. I couldn't sleep well when my husband was using this elbow due to the extra air/breathing noise, so we ordered the OEM part to replace this part. I'd suggest doing the same as it's also possible that along with the noise from the part not attaching as securely as the original, he doesn't get the full effect he needs, so I won't reorder this one.
