Can you compost what’s in your vacuum dirt canister? It depends. If you use your vacuum on hardwood or solid floors and on natural-fiber carpets, it’s likely fine to dump the canister full of dust, debris and fibers right into the compost. But if you used it to clean wall-to-wall carpet (like nylon), it’s not safe for composting; adding those synthetic fibers to your compost can contaminate it. As always, when in doubt, toss it out.
