DIY twice filtered carbon scrubber!

First of all i would like to say this is not a completely original design. I took ideas from two diy carbon filter articles on RIU and just joined them together. This thing cost me about $30-$40 to build but im sure many of you could get it done cheaper. I hope you like it!

Materials:
Aluminium fly screen
Activated carbon sheets (aquarium store-1 foot by 1 foot) I used 2
Activated carbon rocks
100mm pvc elbow
150mm-100mm pvc reducer(or as per your fan diameter)
100mm pvc end cap
Duct tape



Step 1:
Cut a square of mesh and tape it to the male end of the elbow. This is what your carbon rocks will sit on. If you like you can put a pantyhose over this to stop finer bits of carbon dust falling through.


Step 2:
Cut a length of screen 1 foot wide (or as wide as your carbon sheets) and long enough to wrap around your pipe 1-2 times. Rollitup and tape it around the elbow.


Step 3:
Wrap your carbon sheets around the mesh cylinder


Step 4:
Fill up about an inch with carbon rocks. If you put much more than an inch it will impede too much on air flow.


Step 5:
Tape on the end cap


Step 6:
I wrapped it one more time nice and tight with the mesh, just to hold it all together nicely


Step 7:
Attatch to your inline filter. I planned on having this on the inside of my cab because i think it work better sucking air through rather than blowing it through. But it just doesnt fit with my light.


So what stinks???



I hope you guys like this. I just put it in this arvo so im sure sure how effective its gonna be. But i think it'll work fine.
Thanks for stoppin by. Let me know what you think.

Cheers

nice diy bro

i like it. double filtered., that is cool. so how good does it work? can you smell any weed in the room? it seems like if you had the doorto the box shut and the filter running and then you opened the door you might get a whiff. very nice idea.

you where saying the carbon granules will impede air flow, a take a smaller diameter pvc pipe drill holes all over it cover top and bottom with mesh make it so the bottom of the smaller pipes screen is flush with the screen covering pipe then you can fill the whole screen tube with carbon media while keeping that inch thickness all around.

very nice idea. excellent

not bad you can do better though

I will do a DIY to show you guys
