A micron is a unit of measure in the metric system equal to 1 millionth of a meter in length (about 39 millionths of an inch). The average cross-section of a human hair is 50 microns. The human eye cannot see anything smaller than 40 microns in size.
Our pump pre-filters come standard with 5 micron filtration, specifically a 9 & 3/4 x 5 micron cartridge which should be replaced once per year. Sediment, or suspended solids in the water are filtered out down to 5 microns prior to the water entering the high pressure pump.
Depending on the type of humidification system you have, sometimes a Hy-Lok inline “T” filter with a 100 micron filter is included to prevent pump operation fines from entering into the high pressure lines. 100 microns is equal to .003 mm. 1 millimeter = 0.0393701 inches.
To give you a sense of micron sizing in relationship to nozzle atomization, the following sizing is provided for all of our high pressure nozzles listed by size of nozzle output and corresponding orifice size (the tip of the nozzle has an orifice which is laser drilled to exact dimensions which therefore set the exact output of 1000 psi water for atomization):
