It doesn’t matter how much we promote our filters unless you can see why we encourage you to choose them and how they make your oil last longer. So, we’ve decided to explain how these filters work. Our How It Works page includes graphics and detailed descriptions on microns, depth filtration, and more. We’ll recap here but we encourage you to check it out for yourself. You will learn something.
What is a Micron?
A micron is a unit of measurement. SuperSorb® CarbonPads utilize Depth Filtration to trap frying oil contaminants down to .5 micron – that’s a fraction of the size of a human hair!
What is the Difference Between Depth Filtration and Surface Filtration?
All our filtration and treatment media are based on depth filtration, but how does that differ from surface filtration? Surface filtration allows particles to move from the inside to the outside. The filter will stop all particles that are bigger than the smallest hole. So, if you know the size of the smallest hole in the filter you have the filter’s rating or pore size, for example 10um, 5um or 0.5um. Depth filtration stops large particles on the surface, but we trap smaller particles within the depth which is where the name depth filtration comes from.
Advantages of Depth Filtration
- High Holding Capacity- Since the particles are being trapped inside the filter instead of on the surface, the media holds more before needing changed.
- Particle Shapes Vary- Particles you want to retain are not always perfect spheres so if a surface filter has a 1um hole, but the particle is 1um wide and 5um long, it could get through a surface filter.
