Activated Carbon Air Filter

Step 3 Putting it all together

Now that you have the two frames made, you can put everything together. But before you do this, make sure you slide pantyhose over both frames. This will keep the smaller bits of carbon from falling out.

Now, take the bottom part of the filter and glue the frames to it.

While that dries, clean the carbon. During shipping, small bits of dust will fall off. Clean it by placing it in a colander and running water through it. Let it dry and pour it into the filter.

Next, once its full, glue the top on. NOTE: the small hole in the top is used for adding or removing activated carbon after the top is glued on. I just put tape over this to keep the carbon from falling out

If all was done correctly, the fan should fit perfectly into the remaining hole in the top of the filter. Glue the fan in place and you now have a finished air filter.
