While in the first week it had eliminated the odors... unfortunately, they reappeared again, even with a different air filter (which is with charcoal and not plain). Unfortunately, other products I had previously purchased were more effective...
Update: I also used a second bottle... Still, it didn't do anything, unfortunately. It's a shame because the reviews here made me buy it, but in the end, it's not worth it at all

After a useless winter, my car's A/C started emitting a smell when I started using it in the summer. I bought this specific product as a test for its disinfection and I was very satisfied.

P.S.: The product leaves a cleaner smell in the end, which is a bit stronger and noticeable during the first week after using it for the first few minutes when the A/C is turned on.

P.S.2: To prevent the smells from coming back, one should at least 5 minutes before reaching their destination, turn off the A/C and let only the fan work, so that the air vents can dry out and bacteria and mold, which are the cause of the bad smell in the A/C, do not develop.

Very effective in eliminating odors for sure. Very easy to apply. Leaves a nice scent after the process is completed.
