How to make your own carbon filter for a fraction of the cost?
A carbon filter is a device that is used to remove contaminants from the air. It works by absorbing the molecules of the contaminants, which prevents them from being released into the air. Carbon filters are commonly used in grow tents to remove unwanted odors from the air. They are also an essential component of any ventilation system, as they help to circulate fresh air and prevent stagnant air from building up inside the tent.
Step-by-step instructions for how to make cheap carbon filter:
The materials you will need to get started
- Two pencil holders
- A drill
- Activated carbon
- Two socks
- Scissors
Step One: Prepare The Two Pencil Holders
Use the drill to make two sets of holes on the bottom surface of the cups. Make sure that the holes are big enough for the activated carbon to fit through.
Put both of the cups into the socks.
Step Two: Drill Holes On The Bottom Surface Of The Cups
Fill them up with activated carbon.
Step Three: Put Both Of The Cups Into The Socks
-Seal the activated carbon within the two cups by tying a knot at the top of each sock.
Step Four:
Fill Them Up With Activated Carbon
Step Five:
Seal The Activated Carbon Within The Two Cups
Step Six: Adjust The Socks
If the socks are too loose, you can adjust them by tying a knot in the middle of each sock.
Step Seven: Attach It To Your Ducting/Fan
Now that your carbon filter is complete, you can attach it to your ducting or fan using zip ties or duct tape.
