Hello, my set-up is almost ready for purchase, but I’m still having a hard time with the activated carbon filter. I decided on the Prima Klima EC blue 1180m³/h ø160mm tube fan, but I haven’t found the right activated carbon filter yet or it’s not available I was looking at the Rhino Pro activated carbon filter 600cbm / 160mm and I’m not really familiar with activated carbon filters. Do you have an alternative or maybe even a better option? The tent is 1.50×1.50×2.20 in size

I presently use AC Infinity carbon filter and in line duct fan. A 4”-6” would be plenty big for a tent that size. Mine is a 8” with a 69 controller that I can program for lights, humidifier, fans pretty much everything. It is also Wi-Fi and I check my climate from my phone. I was using a 4” in-line fan and carbon filter in a 2x2x4 and it worked well. Good luck with your decision there’s a lot out there. I’m just happy with AC Infinity products.

I have a buch I never use them where the smell isn’t a problem for me.
I believe if that fan you got is 160mm then thats 6 inches
(sry in America here so I use inches)Basically any 6 inch inline carbon filter will work.
Google “6in inline carbon filter” or “160mm inline carbon filter” and should be tons of price options to fit what you’re looking for.
I should add, you don’t need a really “long” one as they can get really expensive and they dont last forever. 18-24 months of use is what Google says they typically last.
Most people that do run them, only do so when in flower to extend the life of them as that’s when the smell starts to kick up.

I have had the best results with ACI brand carbon filters. Simply the longest lasting one ive ever used.

AC infinity makes a refillable carbon filter. I wonder if that would turn into a messy situation pouring carbon.

I take mine (ACI) filter and re-package up between grows and use and it has been working 4 grows plus the one im on now.

I’m going this route with some tweaks when I want to replace. standard carbon filters aren’t keeping up so I want to try something else…
Pulled from different forum
Materials needed
1 5 gal bucket w/ lid
4 gal of activated carbon pellets
3’ section of 4" PVC drain pipe
1 roll of duct tape
1 section of flexible ducting
1 section of blue filter material
1 package of zip ties
1 4" pvc capStep 1
Drill holes in the sides of the bucket and PVC pipe. The more holes the better the air flow. (Note drill the bucket with a fast drill speed helps to keep the burrs down, and the PVC with a slow drill speed prevents the pipe from breaking.)
The end result should look like this you only want to drill holes in the pipe as high as you think the carbon will go you want the first hole in the pipe to be about 3"-4" submerged in carbon. If you drill to many holes simply cover the holes up with duct tape. You can use the PVC cap to plug the end of the pipe that will be in the bucket or just find something to plug the end. I used an empty sour cream container and silicone caulk.
Step 2
Place the end of the pipe on the center of the lid and trace with sharpie marker then cut out as carefully as possible with a razor knife. This is where the pipe will go through the lid you want a tight fit to prevent pipe from shifting in the carbon.
Step 3
You will need to cut the filter material to size and wrap the material around the pipe and the bucket, and secure it with zip ties. This will allow you to use larger holes for better air flow while keeping the carbon from falling through.
Step 4
Trim off excess zip ties
Step 5
Place the plugged end of the pipe in the bucket. Ensuring the pipe stays straight and centered pour carbon in filling the bucket around the pipe.
Step 6
Install lid and run a bead of silicone around the seam.
Step 7
Install the filter on you inline fan. if you have a 4" fan then it should be straight forward if you have another size you will need a PVC adapter to step up to your fan and ducting size. If you have any questions you can post so everyone can see and I will be happy to answer.

Not really. Totally depends on how messy you are. Old carbon can be introduced to your soil.

That’s a great invention, simple and is refillable and cheaper. Great thanks for that post research.
