It's low in ash (under 13%) and granulated, so it packs tight with no easy shortcuts for odour. Its very fine pores (around 0.02 micron) give smells an enormous surface to stick to.

Mount the filter inside your tent or room and have the fan draw air through it, so the whole space sits under slight negative pressure. That way any air leaking out of a gap or a zip is leaking in, not out. And size up: a filter rated about 20% above your fan's free-flow figure lasts noticeably longer, because it never has to work flat out. If two filters share a duct size, the longer one holds more carbon and will outlast the shorter one.\"\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eHow to match a filter to your fan\u003c\/h3\u003e\n\u003cp\u003eStart with diameter. It's simplest when fan, filter and ducting all share one size. If they differ, go for a filter slightly larger than the fan rather than smaller. Ducting and the filter itself add resistance, so your fan will move less air in real life than its free-flow rating says. Choose a filter rated about 20% above the fan's free-flow rate, and remember that every filter works better and lasts longer when the real airflow sits below its maximum.\u003c\/p\u003e\n\n\u003ch3\u003eFull
