Engine wear creates particles small enough to pass through conventional oil filters.
These circulating particles create the most wear.

FilterMag captures these particles to prevent them from continuing to circulate in engine oil.

How FilterMag Works

Moving parts operating inside an engine wear and create metallic particles that end up in the circulating oil. Normal oil filters catch particles larger than 25 micron. 

However, smaller particles pass through the filter and continue to circulate in the oil. These particles are small enough to fit between bearing surfaces to continue the wear cycle.

FilterMag’s extremely powerful magnets trap these wear-causing particles on the inside wall of the filter canister removing them from the lubricating oil. 

Removing these particles keeps your oil cleaner and helps to break the wear cycle, increasing the life of your engine.

“If they did not work, we would not use them.”

We use Filtermags on our Baja winning off-road race trucks because we know they work to protect our engines. We are very particular with our race trucks and quite frankly, if they did not work, we would not use them.—John Holmes
