How many thousand hours is considered an old machine?

Looking at used machines for back up. Wouldn't get a car with over 100,000 miles on it. What is the equivalent in a cpap?

For a back up machine...depends on the price of said used machine and model age as much as usage hours age.

There are some really low hour old machine but they are REALLY old in terms of model age....dinosaurs that I wouldn't want if they were free.
Now a newer model with maybe 2 to 4 K hours on it wouldn't scare me off depending on the price and what I was going to use it for.
If the price was right and I was only going to use it for travel (once or twice a year) or as a back up...I wouldn't be afraid to get a machine with 5 K hours on it. I once gave away a machine that had 8500 hours on it ....it was only for emergency trips to the hospital.

The average user will put 2500-2600 hours a year on a machine. Average life of a machine is 13,000-15,000 hours. If you are looking for a used machine, you should be able to find really good machines with less than 5000 hours for under $250 on Craigslist.

I think I have over 23,000 hrs on mine ... but it's a "dinosaur" legacy model. I do have a couple of back ups 1) another "dinosaur" legacy model, and 2) a newer M-Series legacy model (not sure the hrs on that one cuz I only use it for travel and I don't travel much) -- would that be an "Ice Age" model?

But any working machine is better than no backup machine ... IMO.

+1 rather have one that'll last a couple nights till I can get a replacement than go one night without xPAP.

In about 6 years I have put over 15,000 hours on my PR550auto
. That's with 98.6% usage rate and average over 7 hrs usage per night. I have seen no signs of anything wrong.

From Second Wind that buy and sell used machines:
"The average life expectancy of a CPAP or BPAP machine is approximately 20,000 hours, or about seven to eight years full time use. That said, many times, if properly cared for, these devices will last much longer. Many properly maintained machines will last upwards of 50,000 hours."

" . . . Properly maintained" would in my opinion, mean keeping fresh filters in the intake.
---to avoid over-working the motor by continually pulling air through a clogged filter.
Twice a month is the Medicare guideline. Once a year is OUTRAGEOUS.
Manufacturers who even mention this destructive timeline need to be held responsible.
Determining if the machine has not been ABUSED by this practice is next to impossible,
but the life expectancy could be severely reduced.

It all depends on the filter, basically, the bigger the filter, the less often it probably needs to be changed, which is one of the reasons that resmed specs a longer change interval between recommended filter changes that respironics.

I've been working on my roommate's oxygen concentrator, and it has a true HEPA filter on the compressor intake. It doesn't even specify a change time on that. Just "check during PM/between patients". (PMs are every three years/26,280 hours.)

=========

5000 is the design life roughly 100k miles on a car

they can legally sell cars as new (at least in this state) with up to 2999 miles on it
anything over 150 hours on it would be a used xpap if they had a similar law

I know he's never wrong and he won't admit it, but 5000 hours is less than 2 years use.

Lincare come out and checks mine monthly, test the O2 % and flow. Jim

It Is a old model (Like my "TANK") They had brought our 3 newer units, all 3 failed. right out of his truck...

i only admit to being wrong when i am wrong

i read their documents whre resmed says the design life is 5000 hours
most will run longer

I have reason to take Palerider at his word.

He does not make things up.

So here you say that Resmed claims the design life is 5000 hours, but on another thread (viewtopic/t157071/Should-I-get-a-new-ma ... l#p1202825) you say "design life is 5 years". So which is it? 5 years or 5000 hours?

My recommendation is to purchase a low hours used machine for backup. Get a machine that is the equivalent of your current machine. Rotate the two machines every three months so you are sure both work.

You may pay more than for a used machine with low hours, but over the life of your two machines you should get your money's worth.

I did something like this buying a low-hours, gently used machine with one-year seller's warranty from http://secondwindcpap.com/.
