I have used the Salter cannula since 1997 and was very pleased to find them at such a reasonable price as I am on oxygen 24/7 and use several a month with concentrator, portable, and power chair.

My order arrived quickly, even with a holiday weekend thrown in. Good work! And good ol' Salter Labs keeps me breathing without fuss and strife with their standard cannulae. You can't beat 'em.

I have been serving as a company nurse in a factory for 3 years now. And having a warm plant/workplace, shortness of breath is a common complain amongst the workers here. So having an oxygen tank or concentrator here is a must. This nasal cannula works well with any equipment and I can see that it is not inconvenient for the workers to use. The special style of this cannula works really fine for them as they can freely move without any problems while wearing it.

I love this. I love this over-the-ear style because it gives me freedom of movement while putting it on my face. Even when I move my face and body, it barely bothers me since the positioning is so secure. It's been a few months and it is still firm. Guess I can use it for a long time!

Very comfortable. These last forever!
