Business Waste: Antifreeze Filters
Proper Disposal: Used filters must be handled as hazardous waste if they exceed the limits for metals found in Chapter 173-303-090 WAC.

If filters don't exceed limits for metals and you want to dispose of them in the garbage, you may need a waste clearance from the Waste Characterization Program at 206-263-8528, or e-mail at wc@Kingcounty.gov.

Before disposing, it is a good idea to flush filters with at least two gallons of water to remove residual antifreeze. The flushing water should be used as radiator top-off or to mix new antifreeze.
