IOBIONICS Grow Tent Complete Ventilation Kit: 4in Variable Speed inline EC Fan, 4in RC48 Activated Carbon Filter, Digital Timer Hygrometer, Heavy Duty Rope Ratchet, 4" Aluminum Flex Duct & Duct Clamps

Installation is a Breeze

I/OBionics Carbon Filters are easier to handle, install, transport and remove.

Efficiency of I/OBionics Carbon Filter

I/O Activated Carbon Filter can absorb 105.7% of its own Surface Area. This is Why our small, but powerful filters produce higher CFM and filtration

Extend the Life of Your Filter

To get the optimum product life from your I/O Carbon Filter, it should be used with the provided pre-filter Sleeve. This pre-filter sleeve catches the large dust particulates and foreign materials which if allowed to come in contact with the carbon will ultimately clog the outer surface of the carbon before total internal saturation has been achieved. When this happens it unnecessarily shortens the product life of the filter. It is recommended that the pre-filter be machine-washed or replaced every six months. Extremely dusty environments may require a more regular cleaning program. Ideally, maximum air temperatures should be kept below 90° F (32° C). Relative humidity should be kept below 75% at all times. Remember, carbon will absorb moisture and will take up "space" in the carbon particulate, reducing its life span.

Life Expectancy

There is no given limit to the life expectancy of RC-48 carbon and your I/O Carbon Filter. The total life span can only be governed by the amount of impurities absorbed by the carbon over time. The rate of air movement through the carbon bed, total air impurities and climatic conditions are the factors that determine the speed at which the porous carbon granules reach maximum capacity. The average coal based carbon is around 500 mg/g ID. On the other hand, RC-48 carbon has a guaranteed analysis of 1050 mg/g ID. All this said, as a guide rather than a rule, we suggest that a I/O Carbon Filters will last a typical user around two years.
