Next - Attach filter to fan and size with breadties, its okay if it doesn't overlap

Next - Secure filter with reflective duct tape and airproof the cap by putting reflective tape around the edge, then sealing with electric tape. This also supplies us with a spot to attach our filter.

Next - Trim filter to size, double or triple up as the application calls for, and secure with electric tape or velcro, I prefer the tape because it makes the seal air tight on the edges.

You will notice your fan works a bit harder, this is one reason I use a larger fan, a smaller fan working harder makes much more noise than a larger fan, unless of course your spending $90 on your fans, but if your doing that, go ahead and spend $150 on a filter It's just not for me.

If you need a guide on how to build a carbon filter for a room, or larger grow area, send me your specifications and I'll create a guide for you. You can also create a combination carbon filter/duct silencer - I can help with these as well. For the ultimate trick, we can build the fan, silencer, and filter for an entire room in less than a 3 foot area - This of course is quite a bit more expensive than $10, but hardly the $800 that a whole room filter will run you, and it'll last just as long!

Remember, active carbon CAN BE WASHED AND REUSED which is one good reason to use velcro on your filters instead of tape. However, at less than $10 per filter, who really cares?

If you have created this filter, and your still having odor issues, simply add more carbon filter to your filter by cutting more and wrapping it around the current filter. The filter we created here should be good for up to a 4x8x8 growspace with proper air intakes.

Oh, here are the additional shots of wiring, and then the final product:

This is before I put the fan in and exaust in

Lets try to make this a Sticky + Rep and + Like if you think this should be up top. If it makes it, I'll post my custom $90 cabinet that will flower 4 plants to about 3oz each
