Rhino Pro Grow Room Carbon Filters utilise activated virgin RC-412 Carbon which is highly efficient and lighter than lower grade carbon, and has a longer life span of 2-3years (minimum) before a replacement filter is required. This combined with aluminium tops and bottoms, makes Rhino Pro filters the lightest most effective air purification system on the market. Each filter comes complete with outer 'pre-filter' sleeve (not shown in image).

Lightweight compared to most other filters.
100% Virgin activated carbon.
3-5year life span.
We recommend replacing outer 'Pre-Filter' sleeve every 9-12months for maximum life span of your filter!
To calculate the size of fan & filter you will require: Simply multiply the length x width x height of your grow room in metres which will give you the cubic capacity of your room ..and then multiply that value by either 30 or 60 which is the minimum and maximum air changes required per hour for optimum ventilation in your grow room.
For example : A grow room measuring 2mtrs x 2mtrs x 2mtrs = 8mtrs cubed x30 air changes an hour = 240mtr cubed per hour will need to be ventilated ..as a rule we recommend buying a slightly larger capacity fan than you need, to allow for summer increases in temp and or using a Carbon filter.
100mm x 300mm (4") = 300mtr3 per hr
125mm x 300mm (5") = 500mtr3 per hr
150mm x 300mm (6") = 600mtr3 per hr
150mm x 600mm (6") = 900mtr3 per hr
200mm x 400mm (8") = 800mtr3 per hr
200mm x 600mm (8") = 1500mtr3 per hr
250mm x 600mm (10") = 1420mtr3 per hr
315mm x 600mm (12") = 2400mtr3 per hr
315mm x 1000mm (12") = 4000mtr3 per hr
