Reply from OxygenPlus ConcentratorsJun 19, 2022
I am sorry you feel this way, but as we discussed your machine with you on a Sunday, it appears that there is actually nothing wrong with your machine, and it is working just fine. The good thing about your machine with its built in Oxygen Purity sensor, is that as long as it is putting out Medical Grade oxygen, the green light will be on. You confirmed yours was. This means it is absolutely working fine. There is no disputing that.
Here is a copy of the transcript of our conversation so any one else can make their own decisions.
____________________________________________________
Leslie: can I return a product?
O2+: We do not take returns
Leslie: this product does not work at 3 liters
it is insufficient in raising a persons oxygen level
I want a refund or at least an exhange with a better product
Again, I would prefer to exchange it for a better product
Stop erasing my messages
Can I exchange this product for one that actually works?
One that actually raises the oxygen level
I want a new one
Not a refurbished one
O2+: I do not have the ability to erase your messages.
Which machine do you have?
Leslie: I have DevilBliss oxygen concetrator 5L
O2+: A home unit?
Leslie: yes
O2+: Is the green o2 light illuminated when running?
Leslie: the light is illuminated, the problem is that at 3L it does not help stabilize the oxygen level. In fact, for the patient it goes down.
At 5L, it barely raises it
O2+: What was your name again?
Leslie: Leslie
O2+: And do you remember your order number?
Leslie: 5466
O2+: Ok.
So, At 5lpm the purity will actually be a little lower than if you ran it at 3lpm.
If the green light on the machine is illuminated, that means it is putting out at least 87% purity which is considered medical grade, and the machine is working as designed.
All concentrators operate in the same fashion, and exchanging for another brand machine, or even a new machine, will not solve your oxygen saturation issues.
Leslie: I have a different oxygen concentrator machine that says otherwise. The Other one worked well to immediately raise the oxygen level at its normal average at 3L. This machine does not. It is not effective in at managing the oxygen level.
O2+: What was the other machine
Leslie: Dynarex
O2+: The operating specifications of the dynarex are the same as the devilbiss that you have, right down to the output purity. Change your oxygen pulse oximeter. Your machine is working as designed
Leslie: No it is not. It is not working as designed because the machine is not as strong as the one from Dynarex. This machine simply does not work
O2+: You said yourself the green light is illuminated when the machine is running. That means it is working as designed.
