Common questions
What does the 1122519 fit?
The Philips DreamStation disposable ultra-fine filter (part 1122519) fits 5 Philips Respironics models, including the DreamStation Auto BiPAP, DreamStation Auto CPAP and DreamStation BiPAP Pro. Every one is listed on this page.
How often should I replace the 1122519?
Every month. It works less well as the filter fills up, so it's worth doing on time.
Where can I buy the 1122519 in Australia?
We track 4 Australian sellers for the 1122519; the lowest listed price when we last checked was A$3.17 at CPAP Australia. Prices are re-checked daily and dated on this page.
How do I fit the 1122519?
No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
What happens if I don't change it?
A blocked filter restricts the air the machine draws in, and a torn one lets dust and pollen through; the manual says when to replace it.
Is there anything to reset afterwards?
Nothing to reset: the DreamStation shows a filter reminder every 30 days, but Philips says it is a reminder only and the machine cannot tell when a filter has been changed.
