Cora Ball
The Cora Ball is a capture tool made of recycled and recyclable plastic - so, like every microfiber device, it's plastic used to fight plastic. It's the easiest and cheapest option (just toss it in the drum) and the weakest in independent testing, catching a smaller share of fibers than a bag or an inline filter. Made in the USA with a take-back program; the brand is transparent that it's a mitigation device, not a plastic-free product.
How clear are their specs?
States the recycled-plastic construction and recyclability; the parent non-profit publishes about microfiber science candidly.
