Try also running the heater on full hot and high blower for about 10 minutes on non-recirculate. I notice the odor is at its worst with heat and after the cleaning procedure I ran first blower (no compressor) for 20 with all vents open on high (I used Klima) then heater for 10 to kill off and dry out anything. I was starting to get the smell back after about a month so I ran the heater at full/high again and when do with to recirculate and added a couple of puffs of Ozium into the right foot well so the system would pick it up. Kept the car closed. This morning no scent. I used to spray Ozium into the intake from the top but found that left residue on the intake area. When you remove the filters see if the condenser is wet. I noted that when I removed the filters and gently touched the condenser it was still wet. That is why after the process I now run no recirculate (if able for temperature) and weekly full heat.
I have done various forms of ozone (cans and generators) as well as sprays (Lysol, etc), and also have run high heat. It does work but doesn't last.
I get you point though. If I can't find a solution that will last a year then I will have to find some regular maintenance return as you suggest.
