Inside Ocean Conservancy's Fight to Make Washing Machine Filters the Law

How To Protect The Ocean

Ocean Conservancy's "Not Safe for Wash" campaign is built around a simple premise: the fix for washing machine microfiber pollution already exists, so the fight isn't about inventing new technology, it's about forcing a nearly two-decade-old idea into law. Its own May 2026 poll of 1,010 Americans found concern about microplastics up 32% since 2023, nearly 9 in 10 people concerned, and 81% in favor of requiring filters on new washing machines. The public isn't the obstacle. The real opponent is AHAM, the Association of Home Appliance Manufacturers, the trade group representing the companies...

Your Washing Machine Sheds Up to 18 Million Microfibers a Load

How To Protect The Ocean

Every wash cycle sheds plastic. Last Monday, Andrew talked with Dr. Anja Brandon of Ocean Conservancy about microfiber pollution, and one question from that conversation stuck with him: has anyone actually fixed this yet? In this solo follow-up, Andrew traces a microfiber's actual path, from the moment agitation, heat, and detergent work it loose from a shirt, through the drain, into a wastewater treatment plant, and out the other side into biosolids, farmland, rivers, and the ocean, with a growing body of research suggesting some of it ends up in human lungs and even in the human placenta....

Can Bacteria Actually Eat Plastic?

How To Protect The Ocean

Bacteria that eat plastic sounds like the fix everyone's been waiting for, and Andrew gets sent videos about it constantly. So on this solo episode, following Monday's interview with Dr. Anja Brandon of Ocean Conservancy, he goes looking for the real state of the science. The short version: it's promising, it's roughly a decade of real research deep, and it is nowhere close to running at the scale the ocean plastic crisis actually needs. The bacterium that started this whole field, Ideonella sakaiensis, was discovered breaking down PET plastic in Japan in 2016. A 2025 breakthrough from NREL,...

The 90 Percent Fix Hiding in Your Laundry Room

How To Protect The Ocean

Every time you run a load of laundry, your washing machine sheds plastic. Not metaphorically: synthetic clothing made from polyester, nylon, and rayon releases microfibers with every wash, and depending on the study, a single load can shed anywhere from a few hundred thousand to millions of them. Most of us have never thought about it, because unlike a plastic bag on the beach, you can't see it happening. In this episode, Andrew talks with Dr. Anja Brandon, Director of Plastics Policy at Ocean Conservancy, about the plastic pollution problem hiding in plain sight behind the more familiar...

A New PBS Documentary Wants You to Care About Coral. Meet the Man Behind It.

How To Protect The Ocean

A new documentary called Descent – Into the Blue starts airing on public television stations nationwide on September 1, 2026. It's narrated by Peter Coyote, directed by Rory Fielding, and one of its central voices is Mike Goldberg, co-founder of the Florida Keys coral restoration nonprofit I.CARE and owner of Key Dives in Islamorada. Andrew sits down with Mike for the full, unedited version of the conversation this week's four solo episodes have been building toward: 30-plus years running a dive shop, more than 10,000 dives, and a front-row seat to watching the reefs he built his life around...

Show Me the Receipts: Why I.CARE Monitors Every Coral It Plants

How To Protect The Ocean

Most coral restoration groups check on a sample of what they've planted, often around 20 to 30 percent, and report that sample as if it represents everything in the water. I.CARE checks on all of it. Every single coral outplant gets monitored at one week, one month, 90 days, then one, two, and three years, with no substitute and nothing left unaccounted for. That rule was built in by co-founders Mike Goldberg and Dr. Kylie Smith before I.CARE ever planted its first coral, and Mike frames it as a matter of fiduciary duty, the same obligation he'd expect from anyone handling someone else's...

The Nursery Hack That Pays for Itself

How To Protect The Ocean

Coral nurseries need constant maintenance, and that maintenance is expensive and relentless. When Andrew talked to Mike Goldberg, co-founder of I.CARE, his answer wasn't to hire more staff. It was to let paying customers do it for the fun of it. Mike owns a dive shop in the Florida Keys, so the paying customers are scuba divers, and over the years he's built a funding model so small that nobody has ever really complained about it. None of that makes sense until you understand what coral actually is. It's an animal, not a plant or a rock: what looks like one coral "head" is really a colony of...

He Almost Quit the Dive Business. Then a Coral Reef PhD Student Walked In.

How To Protect The Ocean

Mike Goldberg had over 10,000 dives and decades running a dive shop in the Florida Keys, enough time to have seen the reefs at their pristine best. Then came a coral bleaching event in 2008, and a few years later, Stony Coral Tissue Loss Disease, a still-unexplained outbreak that's killed coral tissue outright across more than 20 of Florida's roughly 45 stony coral species since 2014. At one point his wife told him directly: the reef isn't what it used to be, and it's not getting better. Get out of the business before there's nothing left to sell. He didn't know what to do about it. Then,...

84 Percent: Inside the Worst Coral Bleaching Event Ever Recorded

How To Protect The Ocean

This year, most of the coral on the planet went through heat stress severe enough to bleach it. That's not a rounding error: 84 percent of the world's reef area, across the Pacific, Atlantic, and Indian Oceans, and NOAA had to add three brand-new alert levels to its Coral Reef Watch scale because the existing one had no category for what was happening. In this episode, Andrew breaks down exactly where global coral reefs stand right now: how the fourth global mass bleaching event on record got declared, why NOAA waited until 2026 to confirm it had actually ended, and why every global bleaching...

Everyone in the Tent: How Ocean Treaties Actually Get Made

How To Protect The Ocean

Holly Koehler has spent almost thirty years in rooms most people never think about: windowless UN offices in New York, the FAO in Rome, and what she calls "oftentimes very boring hotel ballrooms around the world," where countries hash out how the ocean actually gets managed. She's the Vice President of Policy and Outreach at the International Seafood Sustainability Foundation (ISSF), and before that she spent thirteen years at the U.S. State Department's Office of Marine Conservation, chairing international fisheries negotiations. In this episode, she walks Andrew through how a grad-school...

AHAM's case rests on its own testing with NSF International, which found filters capture only about 25% of shed microfibers, a number it uses to argue the whole mandate is premature and expensive. Ocean Conservancy claims up to 90%. Andrew lays both numbers next to a stack of independent studies that fall outside either organization's own interest: an external filter capturing 87% on average, PlanetCare's claimed 98%, a Guppyfriend bag's 79-86%, and Connecticut's own government review putting existing filters at 80-89%. Ocean Conservancy's number holds up a lot better than AHAM's once independent testing enters the picture, though AHAM's other objections, a 13-year payback period on the filter's own embedded plastic, clogging and flooding risk, and a real burden on people with disabilities, deserve a fair hearing too.

From there, Andrew runs the actual legislative scoreboard: California passed a filter bill in 2023 and Governor Newsom vetoed it over cost, even though Ocean Conservancy's own economic analysis puts a built-in filter at just $14 to $20 per machine. France's law remains unenforced. New York's bill has passed the Assembly and sits in a Senate committee. Illinois has companion bills moving in both chambers. Oregon's died in committee. New Jersey and Pennsylvania have bills in progress. A federal bill, the Fighting Fibers Act, is on its second attempt after an earlier version died in the last Congress. Nobody knows how this ends, but Andrew makes the case that the technology fight is basically settled and the real one is political.

Takeaways:

Ocean Conservancy's May 2026 poll found 81% of Americans support requiring microfiber filters on new washing machines, and concern about microplastics is up 32% since 2023.
The appliance industry's trade group, AHAM, cites its own NSF International testing showing filters capture only about 25% of microfibers, far below Ocean Conservancy's claimed 90%.
A stack of independent studies outside both organizations (Lint LUV-R, PlanetCare, Guppyfriend, and Connecticut's own government review) lands much closer to Ocean Conservancy's number than AHAM's.
California passed a filter bill in 2023 that Governor Newsom vetoed over cost, despite Ocean Conservancy's own analysis putting the added cost at just $14 to $20 per machine.
Five US states currently have active or recently-failed filter bills (New York, Illinois, Oregon, New Jersey, Pennsylvania), and a federal bill, the Fighting Fibers Act, is on its second attempt in Congress.
AHAM raises some legitimate concerns worth taking seriously, including a 13-year plastic payback period on the filter itself and a real burden on people with disabilities who'd have to maintain one.
