back before anybody started making carbon filters , ozone was the only way to scrub the smell , but yes in high concentrations its no good for you or the plants . if you do use it , make sure to ventilate it out of the house !!!!

Yes, vent the ozone out !
I've had better results putting one at the beginning of my duct run. Gives it time to mix with the air.
And don't run ozone through a fan or a hood, they will develop a sticky brown gunk in them

Just replace the carbon, don't throw out the filter. It's only a fraction of the cost of a replacement, or bake it at 400f for a few hours to reactivate the carbon. I run 70% humudity and filters are running 24/7 they get replaced every 3 grows with no smell issues ever.

There's little to be saved by replacing carbon DIY unless you use cheapo carbon, which doesn't seem like a good solution. Your problem is not caused by the brand of filter. Rather than replace the carbon, take the filters outside and put a 6" fan on it blowing thru at the opposite direction for 45 min- hour. This will clear out the micro dust and leave the carbon clean, almost like new. I do this every 6 months or so. Your humidity is high. Don't breathe ozone. Put the generator at the end of the run. Good luck. -granger

I save a 300 hundred bucks every 3 grows replacing the carbon, and it takes about 15 mins.what do you mean cheapo Carbon? Lol it all works the same as long as it's the right size and it always is where I buy it
Blowing backwards through your filter will not reactivate the spent carbon. It just blows the dust out, and you should have a good pre filter on it keeping the dust out anyways

In my high humidity environment I can't really do a carbon filter. I use an inline ozone generator and it works great. The one I have is "big blue" or something like that. It produces a lot of ozone so you have to vent it outdoors. A few grows back I had a small slit in the duct and ozone leaked into my grow space, it almost killed my plants overnight.

Tree Grower,
15 mins, eh? All carbon is NOT the same. Prefilters only catch the larger dust. All I know is that my filters last and last, and there is NO smell. Blowing the dust out is what it's all about. You do it your way, and I'll do it mine. Good luck. -granger

It's not about your way or my way. It's carbon and it's simple, once it absorbs enough it needs to be replaced or recharged. Your grow might not need as much replacing as mine but at some point it will need to be replaced and not just blown out. Proper way is 830c for 30 mins in a rotary oven, or 350c for a few hours in a normal oven.

Most carbon filters are very much the same, drill out 5-7 rivets, empty carbon, refill and re-rivet.
