Carbon Filter (Do It Yourself)
MYO (Make Your Own)
This design is for smaller rooms, such as a bedroom; but you can make ones for your duct work in the home.
What’s a carbon filter?
“Pieces of activated carbon used to remove contaminants and impurities, utilizing chemical adsorption.
Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media.
This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants.
Carbon filtering is commonly used for water purification, but is also used in air purifiers.”
What you need:
– Atrium Grate
– single legging, the cheap ones that come in the “eggs” are perfect.
– zip ties at least two (for 3″, zip ties must be 11″ min)
– a few ounces (for the 3″) activated carbon.
– scissors, to trim the zip-ties.
– a length of Duct or Foil (to mount it.)
~ $15 (using a 3″ grate)
Where do I find these items?
– Atrium Grate (Home Depo/Lowes)
– single legging (Any department store, Walmart, Sears, Macy’s)
– zip tie, or two (Home Depo/Lowes)
– activated carbon. (Pet or Fish store)
Items laid out:
Pull Stocking over grate:
Apply two zip-ties:
Cut the extra zip-tie:
Apply some tape to the cut parts of the zip-tie so the stocking does not rip during the next step.
Pull stocking over grate:
Pour in the opening of the stocking, a few ounces (3-5) of the activated carbon; make sure to spread it around well and once satisfied pull the stoking tight and tie a tight knot in the end. Keep the stoking tight so that the filter does not loose shape and sage. Sagging would greatly diminish the performance of the filter.
All done; now just attach it to a small AC or fan and let the fresh air flow.
