- Efficiency: The most efficient performance filter on the market
- Restriction: Lower average restriction throughout the life of the filter than any other performance filter available
- Dust Capacity: More dust holding capacity than any other filter available
- Cleanability: Compressed air cleaning only and NO OILING REQUIRED
R2C has broken the barrier between achieving extremely high filtration efficiency while keeping filter restriction as low as the leading low restriction air filters. R2C has tested nearly every filter configuration currently available. That includes the most common cotton gauze filters from many different manufacturers, as well as cellulose (paper), and the various blended and "nano-fiber" products.
What they found was that low restriction invariably resulted in low filtering efficiency and high efficiency came with high restriction. Dust holding capacity (the measurement that determines how fast filter restriction rises when in use) on none of the existing products were up to their standards.
Of course, their standards are pretty high. R2C's PowerFlow Performance Air Filter products were developed by the same people that designed and built many of the military's vehicles engine air intake systems and filters. The same obsessive attention to detail and engineering standards that has gone into those military products have been put into every PowerFlow filter you buy. You get the best-of-the-best when you use one of their products. The first thing to remember about an air filter is what it's designed for, and that's to protect your engine from damaging particulate. If it doesn't do that it shouldn't be on your vehicle ... no matter how low the restriction is.
Cotton gauze filters currently make up the majority of the low restriction air filters (see the section discussing cotton gauze products). When efficiency is addressed by these manufacturers, you usually find some qualifier with their claims such as "adequate for engine protection" and "meets manufacturers' requirements." There's a reason for those ambiguous statements ... cotton gauze filters aren't very efficient!
Engineers from many vehicle manufacturers have addressed engine intake air filter efficiency in multiple presentations and papers to the SAE. The efficiency requirement that consistently comes up is a minimum of 98% initial efficiency with PTI Fine test dust. Other than R2C's PowerFlow Filters not a single product sold as "low restriction" met that recommendation. Not one!
Our PowerFlow Filters easily achieved that mark and then a whole lot more (see the Efficiency Explained section). R2C produce the only low restriction filter to achieve the experts recommended engine protection requirements for engine intake air filters.
That means that a lot of people that have substantial investments in their cars and trucks are driving their vehicles to an early grave using a low restriction air filter, and on their way to the car graveyard they get steadily declining performance because their engines are not being protected from excessive wear by the part that was meant to protect it. You could say they are loving their cars to death.
There is nothing else like the R2C PowerFlow Filter. It is a high loft, all synthetic fiber designed specifically for engine intake air filters. Unlike organic materials (cotton and cellulose) our synthetic fibers stay stable over its entire life. It doesn't shrink or degrade with time and exposure to harsh atmospheric environments. Since the fibers are synthetic they can change the fiber size and shape to maximize efficiency and minimize restriction, so you get extraordinary efficiency and extremely low restriction. The high loft of the filter media gives them exceptional dust holding capacity. In fact, they have almost 3x more capacity at the same filter restriction increases than their nearest competitor. For you, that means their restriction stays lower longer, keeping your engine at its peak output longer than any other filter available to you. In use a low restriction filter with very little dust capacity doesn't stay a low restriction filter for long.
