Extreme Condition Air Filters

Step into the smarter side of filtration with No-Toil Extreme Air Filters - handcrafted in the USA and built to go head-to-head with the world’s best foam filters. These top-quality filters are constructed from premium dual-stage foam and bonded with the strongest glue available, so riders can be confident the seams will not come apart even under the harshest riding conditions. Designed for extreme environments, the inner foam is not flame retardant, but instead features a higher PPI (pores per inch) structure, creating increased surface area to trap more dirt in the most demanding, ultra-dusty riding conditions like desert races. This design maximizes dirt-holding capacity while maintaining strong airflow for consistent performance in brutal terrain. Each Extreme Filter is supplied un-oiled and ready for treatment, allowing riders to apply No-Toil Evolution Biodegradable Air Filter Oil for a custom-prepped setup that delivers superior dust-stopping tackiness, reliable airflow, and effortless cleaning — all backed by a full one-year warranty.
