Filter rating education

What Is a Micron?

Micron ratings help explain particle size, but the correct filter depends on media type, water quality, system condition, pressure, and routine system maintenance.

Micron explanation

Why 1 micron, 0.5 micron, and 0.001 micron are different

Bigger number, larger particles

A 1 micron filter rating applies to filters designed to help capture fine sediment and particles.

0.5 micron carbon filtration

0.5 micron carbon block or carbon impregnated media supports taste, odor, chlorine, and certain VOC adsorption depending on the exact filter.

0.001 micron membrane rating

The TFC membrane source language uses a 0.001 micron rating for membrane filtration and dissolved solids reduction.

Micron rating is not the whole story

Filter media, flow rate, contact time, system design, water quality, and maintenance all matter.
