    is there a difference between putting the filter on the inside over the outside other than it being more stealthy ?

    My carbon filter, like most, has a removable filter medium on the outside that looks like white cotton batting. It picks up dust and crap that would otherwise clog up the carbon. It is designed to have air sucked through it so that the air first passes through the batting. If you blow air through it instead you're going to be blowing the dust into the carbon and I have to believe that would shorten your effective filter life.

    i know what it is now! its the ducting that goes from my filter to the rvk fan it has loads of tiny holes in it im gonna get sum better ducting coz that bit of ducting has to be air tight coz the fan is sucking air through thetiny holes thnx 4 the info:leaf:

    I think that's a great idea apart from the fact that it will double the air flow resistance. Besides filtering the exhaust air twice, the other great part is that the filters do a really good job muffling the sound of the fans and moving air so having one on both ends should really reduce noise.

    do you think the double air flow resistance will burn the fans out???that was the one thing i was worried about.

    Do you?

    Some guy posted ealier about the carbon filter being flipped so the dirty carbon was pushed back out....or something....my point is does carbon actually hold the odor molecules like that? I always thought it just kinda erased them or something.

    I am going 2 add another charcoal filter. That is my only solution. That an maybe better piping. The dollar more insulated crap.

    I will put the new one on the end of the piping. So 2 filters on each side.

    I dont mean to go off topic but I had to post this in case someone sees this as defective or damaged.

    I just recently purchase a "Phat filter" which is supposed to be a very good quality CO2 filter, when I switched it on it sprayed out tiny carbon granules from the blower, I kept it on for a little while but it doesnt seem to stop. Will it eventually clear away the excess granules which is on the surface of the filter or should I return it. Usually it wouldnt be an issue its just that it leaves a tiny layer of carbon granules on the surface of my furniture in the room.

    Ive never herd of an active filter lasting years, you should either repack or replace every 6 months. This is from can filter themselves. Better safe than sry. Always go overboard

    you should be sucking air threw, not blowing threw. If the dust doesn't stop within 20 minutes or so I would return it.

    i had the same problem and the answer is that your pulling air through the filter to fast, the odor needs some "dwell" time in the filter to get soaked in, what i got was a speed control for the fan, think of it as a throttle for the fan you plug it in to the wall then plug your fan in to it and it has a dial on it to adjust the speed, im using a can 9000 with a 4 inch inline fan and i had to turn the fan down to about 70% before it worked now you dont smell shit, at first i thought that carbon filters were crap and couldent clean all the smell but they work like a charm when you run them right, like say your filter is rated at 200 cfm dont pull more that 150 or so through it and your problem is solved, if your handy you can even wire up a dimmer switch like you have on kitchen lights...look up controlwizardproducts.com and its called the speedster, it was like $30 at the grow shop

    Make sure your grow situation is at a negative pressure, by doing this you need all the air to travel through the carbon filter you may need a larger blower,computer fan(120mm). if it still smells you may need a larger carbon filter with more carbon
    surface area.

    You also want your plants to get new air, the air you exhale is what they thrive for so you might want to consider installing a inlet fan that pushed air in the grow situation, if the grow situation is at negative then the air wont come out the inlet hole.

    smells clean.

    got a titan.

    gonna run it 15 and see how long it can go.

    also i need a speed controller. My fan pulls too fast.

    oh wow! i just checked the room. It is clean. Noe of the lingering smells charcoal left.

    Man I was stressing. I turned on my air yesterday and I could smell weed being oushied around the apt.

    My 6 in fn just yeanled the smelly air right through a 6 in filter. I tried throwing in some extra tuning to slow it down. Kinda helped. i also gonna try that speed controller too.

    or just foget the filter altogether. That might be too optimistic. Butmaybe not. I always conservative. I got another one coming I got a good deal on.

    This will save a crapload of money in the long run. Also with smokeing my bud.
