Grow rooms in a home require an extractor fan in order to remove the bad air and improve the air quality of your indoor growing space.
Inline Extractor Fan
Inline extractor fans are created with hydroponics in mind. When this type of fan is employed in the given purpose the carbon filter that will help to absorb any moisture and fumes from passing through the entire exhaust system will need to be replaced on occasion. Carbon loses its effects of absorption after use.
Replacing Carbon Filter
Carbon filters are tubular filters that are encased in a outer sleeve. They are easily accessible in the exhaust fan and are simply unscrewed and the new one is screwed back into place. A carbon filter should be replaced every 12 months. If your grow area is a larger space, as an entire room, you may choose to replace the filter more often. The carbon inside of the carbon filter can be recharged so you could effectively use the same filter several times. Keep in mind the size of the carbon filter you need will be determined by the size of your grow space.
Replacing Carbon Filter Sleeve
The external sleeve of the carbon filter can be replaced easily as well. Simply slip the sleeve off the filter and replace it with a new one.
