What Size Carbon filter do i need?
4″ Budget Carbon Filter “160m3″ 100mm x 250mm = 4” Rvk Extractor Fan – 100 mm A1 = “175m3” We recommend that you renew the air within your grow room once every 2-3 minutes (30-20 times per hour). To understand which size carbon filter is appropriate, first you need to calculate the volume of your grow room using the following formula: Grow room Width x Depth x Height = Volume, for example: Grow room 1.2m Wide x 1.2m Deep x 1.8m High = 2.59 cubic metres (2.59m3) Now that you have calculated your grow room’s volume, you now need to find out the recommended amount of air that needs to be renewed based on its volume. To do this use the following formula: Grow Room Volume x Air exchanges = Recommended volume of air exchanges per hour, for example: Grow room volume of 2.59m3 x 30 air exchanges per hour = 77.7 cubic metres per hour (77.7m3/hr), meaning that the 160m3/hr rated carbon filter is more than ideal for this size room.
