What you will find out

How much life your machine has left

Worked out from its age, the hours on it and how far the battery has fallen from new, against the service life the manufacturer publishes.

What you have already spent on it

Batteries, columns, repairs. Your own numbers, added up, which is the part almost nobody has ever done.

What the next two years will cost

Priced from our own current parts prices for your exact model, not an estimate and not a national average.

Whether parts still exist for your machine

Several models are past the point where batteries or sieve beds can still be ordered. If yours is one, we will tell you plainly.

See your own numbers. About three minutes.

How it works

  1. Tell us what you own.Your model, roughly when you got it, and the hours on the display if you can find them. Every question has a "not sure" option.
  2. See your numbers on the next screen.No waiting for an email. The full report appears as soon as you finish.
  3. Talk it through, only if you want to.An Oxygen Specialist can walk through the figures with you. They will tell you if your machine has more life in it than the report suggests, and they do say so.

No cost and no obligation. Your report appears on the next screen.

A note on prescriptions This tool is free educational material and needs no paperwork at all. Oxygen concentrators themselves are prescription devices, and if you ever need help with that, our team calls your doctor's office and handles it for you. That is not a sales line. It is just how this should work.

You are in good company

Questions people ask us

Is this really free?

Yes. There is nothing to buy and no purchase required. We are a family business in Rochester, Minnesota, and an owner who knows what their machine costs is a better customer whether they buy from us or not.

Where do your numbers come from?

Parts prices are our own, the ones we charge today, for your exact model. Service life figures come from the manufacturers' own documentation. The repair figures come from our service department in Rochester, from the machines that came across the bench in the last eight weeks.

What if I cannot find the hours on my machine?

Tick "I cannot find it" and we estimate from how long you have had it and how much you use it. The report is less precise that way and it says so, but it still works.

Will someone call me?

Only if you want that. An Oxygen Specialist may follow up by phone or email to go through the numbers with you. There is never any pressure and you can opt out anytime.

Is this a diagnostic test of my machine?

No. It is an estimate built from manufacturer service figures and the answers you give us. It is not medical advice and it does not measure your machine's oxygen output. If your concentrator is alarming or you feel unwell, call your provider.
