DIY Micron Filter

Micron filters are filters that can be used to remove impurities such as bacteria, protozoa and microbial cysts. This type of filter is commonly used on water to remove the contaminants to make the water safe for drinking. It can be especially useful for campers, backpackers and individuals who travel in different countries who may not have regular access to clean water. Filters are also used in other applications such as irrigation, aquariums and swimming pools.

Instructions

    • 1

      Place the sharp end of a compass in the middle of a piece of plastic sheeting. Slide the penciled edge of the compass out as much as possible. Hold the end in place and rotate the penciled edge 360 degrees in a clockwise direction to form a circle.

    • 2

      Reposition the penciled edge approximately 1/4 inch from the center. Hold the end in place and rotate the penciled edge 360 degrees in a clockwise direction to form a circle.

    • 3

      Draw a straight line from the outside of the circle to the middle.

    • 4

      Cut out the large circle and cut along the straight line. Cut out the small circle.

    • 5

      Measure 1/2 inch from the right side of the straight line and draw a parallel line to the straight line. Cut along the new line leaving 1/2 inch uncut at the top and bottom.

    • 6

      Measure 1/4 inch from the left side of the straight line and draw a parallel line to the straight line. Cut along the new line 1/2 inch at the top and 1/2 inch at the bottom. Leave the middle section uncut. This will create two tabs. Slide the tabs into the slit cut on the opposite side of the straight line to form a cone.
