Patented FilterMAG™ Oil Filter Magnet Technology Removes Steel Particles As Small As 2-Microns from Engine Oil.
In order for FilterMAG™ to remove minute steel particles from the oil
system, its magnets must have enough energy to hold incredibly fine
particles against the velocity of the oil flow. FilterMAG™'s patented
design employs a focused magnetic force field, that amplifies its
incredibly powerful Neodymium magnets, to generate the immense force
needed to forcibly remove tiny particles below 20-micron from the oil
flow; and retain increasingly smaller particles -- as small as
2-microns -- against the pressure of oil flow velocity.

FilterMAG™'s patented magnetic flux amplifier technology redirects the
magnetic energy normally present on the far side of the magnet towards
the inside of the filter canister. The flux amplifier has to be of a
precise thickness to maximise the magnetic field. The circumference is
adjusted to allow for manufacturing variances to result in a precise
fit & alignment of the series of magnets to the filter canister.
This focuses the maximum amount of magnetic energy within the oil flow.
The successful and proven result is a masterpiece of automotive
engineering.
In real life, FilterMAG™ works by simply placing it onto the outside of
the filter housing where the magnetic force automatically snaps it into
place. The ultra strong magnetic force starts to work — forcibly
trapping unwanted particles "locked" against the inside walls of your
traditional filter.
