active carbon filter

[fhydro]

I just want to testify that an active carbon filter connected just before the exhaust fan works very good. I was paranoied with the smell of the last month of flowering but now i can relax. No odor at all. Don't hesitate any more to get one, it's worth the price.

How much is one, and how long does it work?

they are pricey.. and work well for a few months

you can build your own for MUCH less $$ than buying a pre built one, it is very easy to do ... but i use ozone to keep my smells under control.. requires more thinking since o3 can damage plants .. gotta be careful.. but it is quieter and doesn't require as strong of a fan becasue there isnt the drag of pushing air through a filter

Do you have a "How to FAQ" or any thing?

....To make your own that is...!:)

no.. i could easily make one for ya.. it is extremely easy, and there are MANY different methods.. but briefly here is one of the easiest

take a adapter piece of ducting for whatever size you want to use.. most common is 6'' ... whatever fits your ventilation system will do, as long as the fan is strong enough to handle forcing air thru a filter

you will also need an end cap in the same size, duct tape, metal screen, and universal active carbon filter replacements.. you can find them near the hepa filters, tthey come in a large sheet that you have to cut down to fit your filter... you will use half of the whole thing for this.

take a section of the screen about a foot to foot and a half wide, now connect the end cap and duct adapter to it and roll it around the edges and tape them down... this leaves you with a mesh tube that is closed on one end and connects to the exhaust on the other end

once that is done you cut the filter to fit over the mesh portion of your tube, and roll it around the tube about 2 -3 layers thick.. the filters will have come with velcro straps that you can use to secure it in place

finally, duct tape around the top and bottom edge of the filter, to insure that air does not escape between the edges of the carbon, making sure that all exhausted air goes thru your filter

connect it to your exhaust and bam! active carbon scrubber, and a extra filter for when you need to replace it... as long as you have made your connections airtight, this will work just as well as any pricey commercial option :D
