There should be a button to release the vacuum that is pulled on the canister. This is what causes it to be difficult to remove. Opening a faucet may also help. Oil may destroy the “O” ring. Use the Vaseline.
I always use white litheum grease on my orings and they come of easy. And I have been using this for well over 15 years on the same filter, with no o-ring deterioration.
only use plumbers grease. It is specially designed for these types of applications. If you use anything else on the o-ring, it could begin to break down and fail. If you cannot get plumbers grease than use cooking oil. This is much safer on the O-ring, and will not harm you if it gets into the water system.
