Primary Filter Pads

Replacement filter pads for use with Air Scrubbers and Negative Air Machines, sold in sets of two.

Usage depends on how the unit is running: when operating as an Air Scrubber in a relatively clean environment, pads last longer and need less frequent changing. When running as a Negative Air Machine during active demolition or other dust-generating work, pads load up much faster — replace as they visibly fill with dust, typically around one set per day when dust is being generated continuously.

Key Features:

• Compatible With: Alpine Air Rentals Air Scrubbers and Negative Air Machines
• Sold As: Sets of 2 pads
• Usage Guide: Replace daily (approx. 1 set/day) during dusty negative-air work; less frequently for general air scrubbing

Note: Filter pads are a consumable item — sold, not rented. Non-returnable and non-refundable once purchased.
