When I was replacing some internal tubing in one of my 5 lpm oxycons I found out that there is a 3rd filter inside just before the oxygen goes out to the front panel and then to the patient.

It is a "bio filter" that prevents any pathogens that could be inside the machine from getting to the patient that is already sick enough to require oxygen.
Replacing that filter can improve things a good deal.
Most folks don't know the bio filter is there but I think that Salt City company sends out replacement filter kits that include it.

Good Luck
