Servicing your AIRAID SynthaMax Dry Air Filter just got easier with AIRAID's Premium Dry Filter Cleaning Solution. Specially formulated to clean without breaking down the synthetic filter media in all AIRAID Dry air filters, the new cleaning solution breaks up dirt and other contaminants to restore airflow and performance. Sold in 24-ounce spray bottles, each bottle has enough cleaning solution to service a filter multiple times. AIRAID recommends cleaning an dry air filter every 15,000-25,000 miles for normal conditions, and more often for dusty off-road conditions. To service a filter, simply remove it from the vehicle and spray a generous amount of AIRAID Cleaning Solution to the outside. Let the solution soak in for a few minutes then rinse the filter from the inside out with clean tap water from a sink or garden hose. AIRAID recommends using only AIRAID Dry Filter Cleaning Solution to clean your AIRAID filter. The solution helps ensure a long filter life while maintaining filter efficiency. Like the rest of the AIRAID product line, the new Filter Cleaning Solution is proudly manufactured in the USA.
