Leakage from one of the 4 clips

The filter is nearly one and a half year old, thas maintanance was 3 weeks ago, and last night it started with a leakage from one of the four clips where the filter is mounted.

I have for the moment disassembled the filter, turned the sealing around, installed the top of the filter reverse to avoid the filter is in the same position, after this, the leakage has stopped, but will it last? And should there be done any maintanance on the sealings after a period of time?
A: I would suggest reading through all the Q&A's already posted. You might need to purchase a new seal just to have on hand in case this happens again.
