So what makes AIRAID® Premium Filters the best washable and reusable filter you can buy today? Quality. Each AIRAID® Premium Filter is hand-built using the finest materials available today. And each AIRAID® Premium Filter comes with a Lifetime Guarantee.

MULTIPLE LAYERS OF DEFENSE AGAINST DIRT

We start with multiple layers of surgical-quality cotton gauze. But the secret ingredient that makes AIRAID® Premium Filters different from the competition is SynthaFlow®. All AIRAID® Premium Filters use a synthetic filtration media called SynthaFlow®. SynthaFlow® is a synthetic fiber material that traps the smallest dirt particles that ordinary cotton-gauze performance filters cant capture.

Based on SAE standards, AIRAID® Premium Filters, with SynthaFlow®, capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors filters. The cotton gauze layers are combined with our proprietary SynthaFlow® layer in between either stainless steel or epoxy coated wire mesh, depending upon the application.
