Foam with Frame Filter for Micro Filtrabox (Pre-Filter)
Pre-filter: The pre-filter removes the majority of the submicronic respirable dust, protecting the critical downstream HEPA filter from strain and premature clogging. The filter media is encased in a strong aluminum cartridge to resist contamination bypass. The high surface area mini-pleat filter media ensures high capacity and efficiency for typical applications.
NOTE: The Pre-Filter has now been replaced by a Foam Filter. The foam is washable and reusable. It is recommended that you have 1 Foam Filter with the frame and a spare foam filter on hand.
