Ok so ive heard that people tend to use carbon filters over these and i do have carbon filters on both my grow areas... but im curious as to getting one in addition as there can be a faint smell in the room and ive heard that they are good for killing mould and spores which can only be good for bud - right? The one ive seen is £150 and uses corona discharge - has anyone any experience with them and can give me more info/reccomend?
