The size of the RO prefilter is routinely measured in what micron range?

The size of the RO prefilter is routinely measured in the micron range of 1-5 microns. This range is appropriate because the primary purpose of the prefilter is to remove larger particulate matter, such as sediment, dirt, and other debris that could potentially damage the reverse osmosis (RO) membrane or degrade its performance. Filters within this micron range are effective in capturing particles that are small enough to cause issues but large enough to be effectively removed before the water passes through the more sensitive and smaller pore-sized RO membrane.

Using a prefilter of this micron size helps to protect the downstream components of the water treatment system, ensuring that the RO process operates efficiently and prolongs the life of the membrane by reducing fouling and scaling. This is critical for maintaining water quality and system longevity.
