Common questions
- What does the 1122446 fit?
- The Philips DreamStation reusable pollen filter (part 1122446) fits 5 Philips Respironics models, including the DreamStation Auto BiPAP, DreamStation Auto CPAP and DreamStation BiPAP Pro. Every one is listed on this page. Compatible filters made to the same specification also fit.
- How often should I replace the 1122446?
- Every 6 months. It works less well as the filter fills up, so it's worth doing on time.
- Where can I buy the 1122446 in Australia?
- We track 6 Australian sellers for the 1122446; the lowest listed price when we last checked was A$5.00 at CPAP Australia. Prices are re-checked daily and dated on this page.
- How do I fit the 1122446?
- No tools, a few minutes: 4 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.
