Here is the guide for replacing the filter.

If you notice that the white ACF filter housing is leaking after installation, it is usually because it wasn’t tightened enough. You can follow the tutorial and use the filter wrench to tighten it again.

If it still leaks, you can open the housing and check whether the white O-ring is in the correct position. If the O-ring is missing, remove the filter and look inside the housing to see if it is there.

If you still can’t find it, please contact us for help.
