Active carbon filter

Hi,

I was wondering how big carbon filter do I need for my 12 x 12 x 10 ft area? And which companies are best with comparatively cheap price?

Thanks in advance.


( Looking for a professional consultant )

Will you be using air conditioning in the space, or will you be relying on an extraction fan to keep the grow space temps under control?

probably 2 of the biggest ones. Like for phresh itd be 14 x 39. Scrub constantly with one and exhaust with the other

Stay away from Hydrofarm and Ipower.."new light weight design" is something you don't want to be reading in description.

Filters can indeed be lighter and better, not commenting on the brands specifically. Higher grade carbon flakes weigh less and less of it is required.

I'm liking the Black ops filter I bought. Cheap and works well, I been running it continuously for 25 months. Will be using a new one my next flowering cycle.
