3D printing is known to release harmful compounds (VOC - Volatile Organic Compounds) in the air.
Several studies have shown that activated carbon is effective in removing these compounds.
There are several models of activated carbon filters, but I thought they weren't that effective, so I decided to create my own model.
The K1's rear fan is weak, is just 40mm in a axial fan. That fan don't have much static pressure, so, if I put much restriction will be flow affected.
So, that model was designed to be very effective, so I put 2 stages in a big filter (130mm). Bigger area = less restriction!
The first stage I used a bunch of pellets of activated carbon, they have great capacity of VOC absortion, but have some space between pellets and some VOCs can pass through.
The second stage I used a Activated Carbon Filter Sponge to fine filtration.
Bill of material
- Activated Carbon Pellets (about 80gr)
- Activated Carbon Sponge (size 130x130mm)
Attention:
Use only acid-free activated carbon pellets.
Acid washed activated carbon cause oxidation on metal parts
