Never put ONA in the center of your filter. The fan will just evaporate it within an hour. Its a waste. The filter is for activated charcoal. And if possible change the activated charcoal every couple months if you are on the 18/6 schedule. The coal will last a long time and actually scrub the air where as ONA will just mask odors as they exhaust and for a short period.Try putting the ONA in the center of your charcoal filter. Your inline fan will pull air through the filter and the ONA will give your exhaust a nice fresh scent. It works but it evaporates quickly. Don't put the ONA in a plastic cup, it'll eat through it and make a mess.
I use an ONA air purifier on the outside of my grow room. I only turn the fan of the purifier on when I open the doors for watering and doing maintenance. So a bottle of the liquid can last up to a few months during heavy growth..much more in early stages of growth.
