Rhino FAQ's
Match the collar diameter to your inline fan — a 200mm fan takes a 200mm filter. Then choose the length: longer bodies hold more carbon and last longer before saturating. Collars run from 100mm to 350mm and lengths from 300mm to 1200mm, so there is a matching filter for essentially any fan you are likely to be running.
It gives air more contact time with the carbon on each pass and holds more carbon overall, so it removes odour more thoroughly and lasts longer before needing replacement. The trade-offs are cost, physical space inside the tent and weight on your hanging points. A 350x1200mm filter is a substantial object.
It depends on run hours, how much odour it is handling and especially humidity — carbon absorbs water as well as odour, so a filter in constantly damp air saturates faster. There is no fixed interval. The practical sign is odour getting through while airflow is unchanged, which means the carbon is spent rather than the fan failing.
Before — mount the filter on the intake side so the fan pulls air through it. That keeps the fan itself clean, and it puts the whole tent under slight negative pressure so air leaves through the filter rather than escaping through zips and cable ports. Pushing air through a filter is less effective and dirties the fan.
You can physically, with a reducer, but it undermines both. The reducer throttles the fan at its most restrictive point, and the smaller carbon bed is undersized for the volume of air being moved, so it saturates faster. Rhino covers 100mm to 350mm precisely so you do not have to do this.
