Both filters will stop contaminants from entering an irrigation system, however, the extent of maintenance relies on the type of filter used and the organics or contaminants the filter comes in contact with.

Disc filters are typically used when algae or organic growth occurs inside a system. Clear or white lines can allow sunlight to combine with oxygen in systems causing algae to build up. Algae is very difficult to clean off stainless steel filters. Disc filters come apart to clean and provide more surface area in the event of algae contamination.

Screen filters are available in different micron densities and are specified depending on contaminating particle size. Screen filters are the most common filter type and are available in 20, 30, 50, 100, 150 and 200 mesh sizes; 20 being the largest orifice with 200 the smallest.
