The HUBB Difference


Conventional Oil Filter

  • Has not changed in over 80 years – cannot manage current technology
  • One filter design – made from paper and tin
  • Oil flow slows down when saturated with oil & contaminants
  • 52% Efficiency at removing oil contaminants at 25 microns
  • Standard contaminant storage capacity
  • Does not improve emissions
  • Standard oil change interval

HUBB Oil Filter

  • Made from surgical stainless steel and aircraft quality aluminum
  • Filter-in-a-filter design
  • Improves oil flow up to 5X, thereby reducing engine friction
  • 99% Efficiency at removing oil contaminants at 25 microns (captures contaminants down to 5 microns)
  • Increases contaminant storage capacity by 5X, doesn’t capture oil
  • Up to 30% carbon monoxide emissions and 16% nitric oxide emissions reduction
  • Double your oil change interval*
1 - Oil flows through kidney intake
2 - Oil passes from outside to inside filter
3 - Pressure Differential Valve opens
4 - Secondary Filter – Oil passes from inside-out
5 - 2nd Pressure Differential Valve is used for extreme conditions
6 - Clean oil flows back to engine


The HUBB filter looks and works completely differently than a conventional filter and protects your engine much better.

The difference starts with how the oil flows into the filter. 1) The HUBB filter features two large kidney shaped openings in its baseplate that channels the oil around the exterior of the primary filter. These large openings dramatically increase the oil flow in comparison to a conventional filter.

HUBB deploys a patented filter-in-a-filter design. Most of the oil is filtered by the primary filter 2) which filters oil from the outside to the inside. But when the pressure increases during acceleration, 3) HUBB’s 1st pressure differential valve opens and 4) oil flows into the secondary filter where it is filtered from the inside to the outside of the filter. This opposite flow from the primary filter eliminates cross contamination of the clean and dirty oil, allowing only the clean oil to flow through the center of the filter and back into the engine.

The purpose of the secondary filter is to enable HUBB to keep filtering your oil at higher pressure. Conventional filters do not have this capability and when faced with increased pressure go into bypass mode which contaminates the oil as the filter stops working.

To further protect your engine, the HUBB filter has a 5) 2nd pressure differential valve that opens when pressure become excessive in extreme operating conditions. This 2nd pressure differential valve ensures that the engine is never without oil. 6) And unlike conventional filters, this 2nd pressure differential closes when the oil flow returns to normal.

HUBB’s patented design can increase the oil flow rate to the engine up to 5 times the rate of a standard oil filter and HUBB’s filter efficiency is 99% of contaminants at 25 microns versus only 52% for a conventional filter. In combination with its patented pressure differential valves, the HUBB filter provides superior and longer protection for your engine.
