I bought this in case of a Covid 19 infection.
I have it hooked up to my Bipap machine...I am a polio survivor with night time breathing difficulties...set up on level 2 which provides an additional 90% oxygen to the standard air of the Bipap machine.
It works well and I notice my oxygen saturation is typically a percent higher, and my sleep and dreams are different.
I like the remote control so I can turn it on or off from bed, and can turn the pilot light off at night.
It is quieter than some larger machines, but no battery power which does not bother me for my night time purpose.
Thoroughly recommend, and Natural Ozone were a pleasure to deal with by phone and online.

I have my new oxygen machine sitting in my cupboard - with two over 70 and another with compromised immune system we do not want to be admitted to hospital unless it is absolutely necessary. The machine gives us peace of mind, as my Doctor says - 'one of us is likely to need this one day, it may not be for Covid19, but we will need this before our life ends'. It is an 'Insurance' buy as we do not know what is ahead of us. Thank you for fast service, great communication and an excellent product.
