How effective is a carbon filter.

Ive tossed them as well. Are you talking about the ona gel stuff or the solid chunk thing?

I was referring to the gel. Never seen one of those solid "chunk" thingies. :thumbsup:

Carbon filters work good. If you have especially stinky ladies then a small odor can pass through and if its not checked then you can end up with a very obvious odor build up in a room over several hours.


I need to get a jar of ona for my grow area since the smell is starting to pass through the filter and building up.

I run into that toward the end of the filter carbons life. If I have to crank the fan speed up, a little odor sneaks through. Sometimes giving the filter a couple sharp raps (like fixing an old TV, ) will shift the carbon around enough to give a path through some fresher carbon. The Ona does a great job on what little gets through.
