Irrigation Filtration

Irrigation filters have a mesh rating and micron rating. Mesh count defines the number of openings per linear inch, whereas the micron rating defines the size of the opening. As such, these ratings are always translatable with one another. For example, 80 mesh is always 200 micron.  Generally, 80 mesh is used for sprinkler zones and 120-150 mesh is used for micro/drip zones. Consult the manufacturer's specifications of the products you are trying to filter to see what they recommend.
