funny you should post that I have looking at filters and fans today. Phresh filter i think is the best one. looking at A Vortex 4inch fan also.
Is there somewhere on here that shows how to hook them up in a room ?
Percentage of open air mesh—the inner and outer cylinders of traditional charcoal filters are made of a perforated metal mesh. Depending on the quality of machines available to the manufacturer, the percentage of openness versus percentage of metal (closed-ness) will determine what percentage of the total volume of air being pushed into the filter makes it easily to the charcoal for filtration. The more metal in the way of the air, the less the filter can clean. Phat filters have a 53% open air mesh. Phresh, Rhino and Dragon have a 51% open air mesh. CAN filter and Pro filter haven’t made this knowledge available to me so I cannot comment on those two brands.
These guys got Phat Filters cheap
Phat Filter Carbon Filters
some key tips.
make sure ur exhaust fan does {...} exceed the max CFM of the air filter, better to have a bigger CFM filter then the exhaust fan.
Also, don't send the hot air from a HID light through the carbon filter and the filter will last longer.
{...} I asume you meant to type the word "not."
also, if you can, keep your runs as short as possible and use semi-flexible aluminum smooth duct wherever possible instead of the flexible accordion stuff.
Is that like single-wall vent pipe?
Probably made things a little quieter as well.
good to know, thanks for the infoive been using a phat filter for my exhaust and has worked great for smell. my other grow that failed smelled really bad and it kept the smell out
yup meant to say not.lol.. thanksAlso, don't send the hot air from a HID light through the carbon filter and the filter will last longer.

wow never knew that, thanks. i like that hose also because they dont blow out like the other ones if their a bend, i use to have to replace them all the time. the one i got at HD or lowes is insulated and works great. never buy ur vent hoses at the hydro store its a big rip off, always at a hardware store.also, if you can, keep your runs as short as possible and use semi-flexible aluminum smooth duct wherever possible instead of the flexible accordion stuff.
If I remember correctly, the ribbed accordion stuff produces 50% more static pressure than the smooth stuff.
Switching to semi-rigid duct dropped my temp by 2 degrees.
when i used the insulated hose from HD or lowes it made things allot more quite. not to sure why you would put a shirt over the opening? that would just block the air flow and make ur setup less effective.Is there a way to quite the exhaust? I think i read something about putting a shirt over the opening
That semi-rigid ducting is great. Beats the accordian stuff hands down. Careful when you bend it though.

Pretty little pics, Irish.
Soon you'll have to start holding up gallon milk jugs next to those plants, lol.
You might need that Asplundh wood chipper come harvest time, after all.
