Common questions
What does the CFX-G100/GB fit?
The Samsung CFX-G100/GB 2-in-1 Filter (AX34T3020, AX40T3030) fits the Samsung AX34T3020WW/SA and AX40T3030WM/SA. Compatible filters made to the same specification also fit.
How often should I replace the CFX-G100/GB?
Every 6 months. It works less well as the filter fills up, so it's worth doing on time.
Where can I buy the CFX-G100/GB in Australia?

How do I fit the CFX-G100/GB?
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?
The fan works harder for less airflow, and the carbon layer stops taking smells out well before the filter looks dirty.
How do I reset the reminder?
After fitting the new filter, hold the sleep mode / filter reset button for more than 3 seconds.
