Taking care of the smell

What is the best way to take care of smell. Mine is in a closet and I have about 8 with bubbleponics.

I was thinking about getting a air purifier, ona and some baking soda.

Should I get something that has carbon filters instead? Could anyone recommend anything?

if you can arrange the ventilation then a carbon filter vented outside the room is the best option.

ona gel alone works fine but you'll go through a fair amount

Ive heard that air purifiers do not get rid of the smell very well if at all, carbon filter is better I think

if u can instal a exhaust put a carbon filter in it...just think how bad your bag stinks, your growing the whole damn plant..smell is a bitch

thanks guys i appreciate the help
