Common questions
What does the 38815 fit?
The ResMed AirMini air filter (part 38815) fits the ResMed AirMini. Compatible filters made to the same specification also fit.
How often should I replace the 38815?
Every 6 months. It works less well as the filter fills up, so it's worth doing on time.
Where can I buy the 38815 in Australia?
We track 6 Australian sellers for the 38815; the lowest listed price when we last checked was A$1.00 at Amazon AU. Prices are re-checked daily and dated on this page.
How do I fit the 38815?
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?
No reset: ResMed's AirMini guide has no filter reminder to clear.
