No worries inserting the filter the one and only way.
Problem is the rubber frame of the filter is soft and gravity does a job on the filter.
When shining a light from the "dirty side, light will pass the filter shining into the "clean side". Flimsy filter that does not support itself, instead sagging and letting light and possibly dust/ dirt pass.
I had high hopes fitting this filter, instead dissapointment came my way.
Have already fitted a new original filter ande gotten my snorkel back in position.
Dirt, thou shall not pass.
Would love a good solution.

Best regards

Anders
