carbon filter

does anyone know where you can pick up a carbon filter(besides ordering one online) n how much the go for.thanks

Make one your self. It's just a wood box with a fart fan, 3 to 5 furnace filters, one return grill and some plywood. Use active charcoal from the local fish store 5 pounds each layer. Tap all the layers of filters together at the ends so all the air that goes in goes through and out the other end. A little gap in the top will equalize the pressure and make better use of the full size filter screen. Another gap under the filter and between the fart fan and filter will also increase the efficiency of the charcoal scrubber.

You can vent it outside or just return the clean air back into the room depending on your need.

It's that easy and it does work

What do you mean by fart fan? What kind of fan should be used and how powerful?

A fart fan is slang for bath room ventelation fan.

The size of the fan depends on the size of your room. You need to vent out the air in 3 min time so do the math. LxWxH

Does that help

how about a step by step, materials and such sticky?

This is a real concern for most people.

Yea i checked out a step by step pic tutorial on building one at hempcult....

its a fucking project if you aint a carpenter...

Had all these trays and filters and you needed to use a measuring tape and drills and when it was done it looked like a nice dresser drawers setup....on frickin wheels.

but way over my time limits...

I said fuck that...i just go buy a filter and a fan.... :)

The link is in this post. by dakraysziethug. Just click on it and you will see what hardon is talking about. Looks like alot of work, but I think I'm going to attempt it.

YEP
Like the idea of that.

Although like to have the fresh air coming out flex tubing instead of ground level.. only for light heat issue.

they have those carbon wraps that you can cut to size.. figure a layer of that wouldn't hurt...
