Fuel filters

Disposal guidance for eligible businesses

sometimes hazardous

  Disposal requirements vary

Dispose used fuel filters in the garbage after you drain the fuel from them. 

  • Turn the filter upside down to drain the fuel into an airtight container. Dispose of the waste and bring it to your preferred hazardous waste collection site (eligible businesses only).
  • Allow the drained filter to dry out for two days and dispose of dry, drained fuel filters in the garbage.

If the fuel cannot be drained from the filter, take it to one of the household hazardous waste collection sites. Businesses must bring a completed disposal form to the disposal location. Businesses are allowed a maximum of four visits per year.

Frequently-Asked Questions

Your business is eligible to receive no-fee hazardous waste disposal up to four times a year if it is:

  1. Located in King County
  2. A Small Quantity Generator (SQG), meaning that you do all of the following:
  • Produce less than 220 pounds (about 25 gallons) of hazardous waste per month
  • Produce less than 2.2 pounds (about a quart) of acutely hazardous waste per month
  • Store less than 2,200 pounds (about four 55-gallon drums) of hazardous waste

Eligible businesses should plan to fill out a business disposal form to qualify for no-fee disposal at any hazardous waste collection site.

  • Complete the form. You can find a digital copy online, or download the PDF. Print two copies and bring them with you to your preferred collection site.
  • Prep for disposal. Keep items in their original containers and label those products that are unmarked. Be careful not to mix different types of waste and secure items so they do not spill or tip over during transport.
  • Drop off your hazardous items. Bring your items to a disposal collection site. There’s no fee—the service is funded through your utility bill.
