An OEM 1st Stage Replacement Filter (blue filter in photo) for our PureAir Dust Collector. This filter pre-screens larger particles and provides protection for the next 2 filters. Filter also fits the Delta (#50-785 & 50-860), Jet 708620B, many other ambient air cleaners with a nominal 12" x 24" opening (actual filter measurement is 11-5/16" wide x 23-5/16" x 3/4" thick)
Filter will last approximately 3-6 months depending on dust exposure. Useful life and filtering efficiency can be improved by periodically blowing or vacuuming off the filter. USA
Attention: The PureAir Dust Collector has been discontinued and is no longer available, however, due to the large number of units still in use, and the cross-compatibility with other brands, we will continue to sell replacement filters until further notice.
