EDIT: last update i'd only suggest these filters for a small grow. You're better off just getting a can type carbon filter.
I'm starting this thread to talk about these filters because I dogged them pretty hard in my threads and somewhere else, and I was wrong.
These filters are small lightweight and they work great.When i first got it, i liked it. i had been having issues with an inadequate fan and filter. Then I could smell that NYCD, not real strong, but enough, and thought they just sucked.
I edited posts in my thread and yelled about them not working and saying don't buy them.
I was wrong.
Now I still have to go back and print retractions in my grow threads.
Old Soul suggested that maybe I had a leak. I had went through and caulked every corner and around the ducts where they go through the ceiling. I told him, no i don't have a leak! Then I found the hole in the ducting.
Venturi effect pulling unfiltered air right out.
I fixed the leak and the smell went away. I walked all around the house sniffing. No smell.
Now, I have 2 4" vortex fans and one is hooked to a DIY carbon filter that works great. (with the right fan, not so good with the old little duct fan i used to have that caused me to go buy the fiber filter.)
A little over a month ago, I decided to unplug the diy filter and just exhaust through the Fiber Filter. Not one bit of smell. So now I have an extra fan and filter for a future project.
I have two of the 4" filters, so I can change them out when they get dirty. Then it's outside with the dirty one to hose it off inside and out. Then shake it out and let it dry.
I use the triple layer/single pass filters. I also have a single layer/multi pass scrubber, but don't need it. I might set it up in my office just to help with the smell from smoking joints and bowls, and from trimming. But most of it gets sucked into the closet and through the filter, so it's not real bad in the office.
I highly recommend getting these filters. They can be found for 55 or 60 bucks for the 4". I know most grow store websites sell it for more like 70-80 dollars. pm me if you want the site I'm talking about. It's the cheapest i found, and I looked all over. brown box shippers with a business supply sounding addy on the box.
