If the canister was installed with no lube on the "O" ring, you will probably have to use the canister wrench. I lube the "O" ring and can remove the canister without the wrench.
BTW, use something like Danco silicone paste and DO NOT USE a petroleum based lube like Vaseline as it will deteriorate the "O" ring over time.

Because some here have had real problems with the bolted in filters I have suggested removing them all together.
Bypass it and put it outside in this or something like it.
