Measuring Bag Flat-Width

To measure flat width:

Lay the filter bag flat on a table and measure across the width of the bag.

For example: a 6” bag has flat width of 9.5”.


There is also a simple way to convert the flat width to a diameter.

The formula is:

2 times the flat width divided by 3.14159, or 2 X flat width ÷ 3.14159.
