My experience with ONA was that it is a fragrance, it did not effectively "remove" any odor. And to provide enough fragrance to cover the "damn skunk", the smell of the ONA was then very conspicuous. It was not an effective solution for me.It is basically a scented gel.
I very quickly and with MUCH relief got a carbon filter. NO smell now, not even a hint.
I will not encourage anyone that actually needs to conceal the smell of their cannabis to rely on ONA, I think it would be foolish to rely on it.
