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 can’t 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.

LIFETIME GUARANTEE
All AIRAID Premium Filters are built to last "for a lifetime" guaranteed. Each AIRAID Premium Filter body is made from hand-poured urethane that won’t crack or shrink in the high-heat environment found under the hoods of today’s vehicles. Each AIRAID Premium Filter is 100-percent washable and reusable and come with AIRAID's exclusive "No Hassle" Warranty.
