I’m surprised this doesn’t seem to have been discussed here, but I’ve plugged the Airlife 001851 filters onto the end of my CPAP hoses for probably a decade. They’re not terribly expensive by the case if you shop around (under $2/each), only mildly restrictive if you swap in a new one weekly, spec’d to filter >99% of bacteria and viruses, and so also must capture larger particles as well.
I used them with one of the now recalled Philips Respironics self destructing foam machines, and I now wonder if these filters saved me from injury.
With some machines I would think pressures may need to be slightly increased, but my Resmed APAP seems to auto-adapt to the slight restriction from the filters without any intervention.
I think they’re a reasonable precaution/prophylactic measure to guard against pollution, infections, whatever microbial nasties might decide to breed in the machine/hose/reservoir, and self-destructing foam.
Thoughts?
(Note: I have no relationship with the manufacturer, just a satisfied customer sharing info.)
