Outerwears' pre-filter covers are used to filter out fine dust and debris as small as .005” which can clog paper, cotton, and synthetic air filters and help prevent water from soaking the filter. This extends the service life of air filters, and allows the filters to be effective for longer periods of time in harsh environments. A wide variety of sizes are available for different sized air filters. Pre-filters in black, blue and red are stocked and other colors are available for special order.
