GRUNDIG Oxygen Concentrator, Portable Oxygen Generator 93% Highly Concentration Oxygen Machine 1-6 L/min Oxygen Flow Adjustable Oxygen Maker with Anion Function for Family Travel

I bought this for my grandad who having a breathing problem, albeit temporary though, after searching on the internet decided on this particular machine. I am very pleased with it, easy to use, works well and has proven to help my grandad reduce his breathlessness. There are many types to choose, highly recommended!

Defective Item, From first day no supplied Oxygen, But we are thinking its working, for lack of oxygen my mum was admitted to ICU at the hospital. At the hospital, the medical team checked the machine and discovered that the machine release only air no oxygen.

This is primarily designed as a PORTABLE oxygen generator. If you want a quality machine for this purpose then I would have given it 5 stars and kept it…but I returned it after getting it out of the box it’s really too small for constant home use although the manufacturers do say this can be done.Please look at its dimensions before buying…I know they are there but that’s my fault I suppose good return policy well done Amazon!

Purchased this August 2022 due to breathlessness from COVID, believing the brand was good and it wasn’t cheap. Haven used only twice, I stored it away nicely. Fast forward to July 2023,I had a need to use this as my saturation dipped after a flight. No oxygen came out! Machine came on, working right but no oxygen. Did all the required troubleshooting to no avail. Had to eventually go to A&E that night which would’ve been avoidable.

In my case it does not put out the oxygen level set on the display.This makes it useless
