Philips machine failed within 4 years. Is this normal?

I tried to find posts about this, and the only one I found was complaining about ResMed. I have been using a Philips Respironics BiPap since like 2016, and it finally hit the fan this year. I've posted about that, but when I did get back to my doctor I asked him if that was normal and he said they generally do get replaced every 4-5 years so he did not seem surprised (he also said he was not a fan of the particular machine I was given). 

And then I saw that post about ResMed when I searched, so I was wondering for the people who have been on the therapy for over 5 years, does your machine usually break at that point?  I am just wondering if it's normal for them to stop working and expected that we will replace them every 4-5 years.

I have over 17000 hours on a Resmed Aircurve 10 Vauto after over 5 years. It still runs as expected, but is closing in on replacement. Standard warranty on the Resmed is 2-years, and most DMEs warrant for the life of the machine due to insurance and Medicare requirements. The reliability of the Resmed has been very good from what I have seen, however there were a number of machines that had bad pneumatic blocks (fans) that developed noise. Nearly all of those were replaced under warranty. Other failures are nearly non-existent. The Resmed implementation if both auto CPAP and VPAP auto is considerably superior to Philips for a number of reasons. Resmed is preventive of events, while Philips tends to be reactive. The deliver of pressure changes from IPAP to EPAP is much smoother thanks to Easybreathe™ which is far more comfortable than the comparatively square-wave pressure of Philips. Finally, only the Resmed gives you the ability to make fine adjustments to trigger and cycle sensitivity and time of inspiration (IPAP). Mostly it just runs seamlessly, but the adjustments are useful in some cases.

I'm aware of both Philips and Resmed machines that are mechanically sound up to 25000 hours, but there is no doubt that they all need updated and replaced eventually. 5-years is considered standard.

Technology, probability, power surges, and time all conspire against you. Pretty much why the manufacturer's MTBF (Mean Time Before Failure) is only an indication under most circumstances, not a guarantee. Or as they say, IT happens.

My Resmed s10 is 5 years yesterday and still going strong. I will look to replace it any day now just to be safe.

Hrs on the machine is more accurate possibly because some folks sleep longer hrs than others and pressures that the machine is under are also determining factors IMO. I'm on my 2nd Resmed Autoset 10 and the 1st machine is my backup machine and was working fine with approx 5 years on it.
