Cora Ball Cora Ball
A spiky ball you toss in the drum to catch microfibers - the easiest and cheapest option, and the weakest. Made of recycled plastic; a low-effort first step, not the most effective one.
The verdict: Mostly plastic
Made of recycled (and recyclable) plastic, so like every device here it's plastic used to catch plastic. You just drop it in the drum; its coral-like stalks gather shed fiber into fuzz you periodically pull out. It's the lowest-effort and cheapest capture option, but also the weakest: independent tests put it around 26-31% reduction, and one study found it didn't significantly cut fiber by weight (it catches longer fibers, misses many short ones). A reasonable easy first step; an inline filter or the Guppyfriend bag captures more.
Verification: Manufacturer confirmed
What it's made of
| Part | Material | Water contact |
|---|---|---|
| ball recycled, recyclable plastic; made in the USA with a take-back program | Plastic other / unspecified | No |
A soft spiky ball created by the Rozalia Project (a marine-debris non-profit) that you toss loose into the wash with your clothes. Every few weeks you pull the collected fuzz off the stalks and bin it. No install, no consumables.
Pros
- Easiest option - just toss it in; cheap, durable, recyclable with a take-back program
- Works on the whole load with zero setup
Cons
- Weakest capture (~26-31%), and may miss shorter fibers by weight
- Itself recycled plastic - a mitigation tool, not a plastic-free item
