Non-Rebreather Oxygen Mask with Ordinary Connector, 7feet Length 6mm Oxygen Tube, DEHP-Free and Latex-Free Materials,5 Pack (for Adult)

Fit perfect, quality good, paid 14.00 for one with prescription from medical house last time, these are better than that one !!!

The rebreathing bag is too small and the neck of the bag collapses on inspiration.

To start off, the big Issue I personally had with these is the fact that they were packaged in just a tightly wound folded over bag. I know this was probably done to conserve space for storage or shipping but this causes the masks to bend in several places causing improper sealing. Usually they are folded once like a taco or hot dog but this bag was folded in half twice.Aside from the packaging issue, they work ok. The bag doesn't inflate at all unless you plug all the outlets and breath in like blowing up a VERY thick ballon. the o2 flows through these even without the bag obviously but the bag shouldn't be that hard to inflate. Some people may think that the deflated bag means it isn't working and may discontinue use causing an annoyance. They still work for delivering oxygen, just wastes more.

This 5 pack of GlobalRoll Non-Rebreather Oxygen Masks with Ordinary Connectors are a pretty good quality, not hospital-grade, but will work fine as long as you are using it correctly. You must be using a high-flow device, or you may run into a bit of a problem.I'm mostly homebound, and use a large portable oxygen concentrator, so these will come in handy if they are ever needed. I am pretty stable right now, but if I get sick, it's a different story.These are for one time use only, so the parts are the quality expected, pretty much disposable. I'm happy to have these in case I need them, and would definitely recommend them!

My dad is a lung transplant recipient, and he uses oxygen at home a lot. On rare occasion he has a crisis where he feels like he can't get enough oxygen, even with his nasal cannula or regular mask. Recently in the hospital they used something similar to this on him, and he said he wished he had something like that to use if he has a bad episode. So I ordered these in case he might need one. My mom is a retired RN, so she will be the one who attaches this to his oxygen tank if he needs to use one. I watched a video on how to cover the check valve to pre-fill the bag with oxygen before applying the mask, just in case I have to do it. Of course I would prefer my mom do it as she is more qualified, but it didn't look too complicated.The XL size is good for adults. These seem to be good quality. I like that they come individually wrapped and each one has tubing attached. Since they are individually wrapped they can be put into a travel bag easily to take on errands, trips, or anywhere that you think you may need to use one.I hope that my dad won't need them (I hope he doesn't have any more episodes), but I'm glad to have these on hand.

I like these non rebreather oxygen masks. I ordered XL for my husband. He’s a big guy at 6’2 and 215 pounds. The mask fit well and did the job. The quality is good. This is a five pack so good value as well.

These seem to fit great. Minimalist packaging. Came just in a sealed bag but with no branding or anything else. They worked totally fine with my nebulizer. Seems to be latex free which is a pro for those who are a little iffy around the substance. I haven't noticed any issues with my exhalation function but some others have pointed out something along those lines so be sure to check the mask before setting it up.The material is soft and flexible yet sturdy. I can recommend these!

The anti-kink hosing is great, but just about everything else about this mask is terrible. Upon first exhale one of the two exhalation release valve disks popped right off. The oxygen storage bag is way too small to take a full breath on, and there is no anti-suffocation vacuum relief valve to allow ambient air in when the bag is fully deflated. I have reduced lung capacity and the bag barely fills my lungs half way before it is empty. Additionally, the check-valve that allows the bag to fill isn't rigid or secure enough to allow the bag to fully inflate from oxygen pressure, no matter what flow rate is used - it simply presses open the valve disk before the bag is even close to full and the positive pressure then opens the also weak exhalation valves, wasting oxygen. The mask is also very very small despite supposedly being "XL size", and again, I have a smaller than average face size. If the mask actually fit properly and sealed well then it would be a suffocation hazard because of the bag being so dangerously small.This "XL" mask and bag might be okay for a very small child but it not suitable at all for even a 5'3" adult like myself.
