Rostar Filters is the U.S. aftermarket's largest independent cabin filter manufacturer. With headquarters in Oxnard, CA and locations in North Carolina, China and Hong Kong, Rostar has been manufacturing filters since 1979. There is no "Rostar" brand as we have no retail presence.
Our business is supporting your business. This means that we supply our customers without competing with them. While cabin filters are our specialty, we also supply air, fuel and lube filters for automotive and commercial on and off-road applications. Rostar offers the most complete cabin filter portfolio in North America.
Our time to market is so swift that our customers are often the first to market with new applications; something we know they love. If you are looking for a dependable, predictable, filtration business partner, look no further.
