Doesn't stink outside my grow room.
Are you extracting and removing air or running sealed and scrubbing?
What size and brand of filter on what cfm fan?

Your extraction should generate some negative pressure if you want to avoid smells.

Smells got me busted by a grumpy next door neighbor. When I grow again, I will take it a lot more seriously.

I double filter. I grow in tents, but I think the theory would hold up in other spaces as well.
I have a 4" carbon filter inside the tent before the 4" inline fan, a 4" to 6" duct adapter, then a 6" carbon filter at the end of the ducting run where it's released into the environment. Zero odor except carbon smell.
I always get a filter rated for more than what a fan can do, it gives the air a better chance to be cleaned.
I think I read before about negative ion generators affecting plants somehow, not really sure. I guess that would only matter if your intake was recirculating the treated air.
You absolutely need negative pressure, air being pulled out a little faster than it can come into the space.

I remember ozone generators used to be a thing for odour control in grow rooms.. I think

Oversize the filter and extract to a room or extraction box that also has another stationary carbon filter. When I ran HID's and had a hard time running a sealed room I often ran two filters in the tent, one stationary in the bottom and one in the top for exhaust. The exhaust fan later going to an enclosed box with another filter and exhaust fan going outside.
You can do filter--->exhaust fan going to a sealed box with another filter endlessly to remove any possible smell. I've used small tents for this purpose and you can do as many steps til you feel safe with the smell and extraction outside. I've grown in apartments in illegal states for years like this and never been caught or had any neighbours complaining about smell.
The police regulary parked under my exhaust window living in a Capital city.

If hes getting smells from the room theres some type of escape, ozone is gasmask toxic... That type of setup needs to be very carefully planned out.
