Effective treatment requires the exchange of air in the growing area in a period of 5 minutes. Compute your requirements by multiplying the width times the length times the height of your growing area to obtain the total cubic feet. Divide this number by 5 to determine the proper filter size needed.

For example, if your growing area is 8 feet long by 8 feet wide by 8 feet tall, it contains a total of 512 cubic feet. To treat this area in five minutes, you would need to use a fan with a CFM (cubic feet per minute) rating of approximately 102. The GrowBright fan that comes with this system is rated at 590 cfm so this combo is good for any medium to large sized grow room! It's always better to have a little more filtering than a little less for the most effective results.

This heavy-duty filter successfully eliminates odors for up to 18 months! These filters are lightweight and perfect for your grow room.

Why do I NEED a Carbon Filter?
Carbon Filters use activated carbon to filter particulates out of the air. The result is a totally clean, odor free environment for your plants to grow. Carbon Filters are simply the best way to remove any odor your plants or growing area may emit.

How do I use a Carbon Filter? 
Carbon Filters are very easy to use. Simply attach flexible ducting to the end of your carbon filter and onto the intake side of the Inline Fan. You can either use it as a ventilation fan to filter the air exiting your grow room, or you can use it as a "scrubber" recirculating the air inside your grow room. The inline fan comes with a grounded power cord and mounting bracket, so it is very easy to get set up.

How long will this filter last? 
The Carbon Filter will last up to 18 months of continuous use. Humidity is the #1 killer of Carbon Filters so make sure you keep your humidity level below 70% for maximum usage from your carbon filter. Yes, you can refill the filter with new carbon if you need to in the future, but we suggest simply buying a replacement filter (no fan replacement necessary). The reason we suggest a new filter is because they pack the carbon inside the filter so efficiently at the factory (packed bed), and it's difficult and time consuming to try pack it that tight at home.

Why are Carbon Filters my best choice for air quality / odor control?
Other odor control methods may try to mask odors, like using sprays, odor gels or even incense. These masking methods only end up making your grow room smell like your plants AND the masking agent. Ozone generators are good but can be dangerous to both your health and your plant’s health if not properly used. Carbon Filters are 100% safe and 100% effective. Carbon Filters actually remove the odor particles from the air - it doesn't "mask" the odor or neutralize it - the carbon filter actually removes the odor from the air. After 18 months simply remove your spent filter and replace it with a new one - it's quick and easy. Carbon Filters are so popular because of one reason - THEY WORK.
