Every time we do laundry, thousands of invisible microplastic fibers shed from our clothes and flow down the drain. These microfibers travel through wastewater and end up in rivers, oceans, and even the air we breathe.
They’ve been found in fish, drinking water, and even human blood. It’s one of the most pervasive forms of plastic pollution — but unlike many environmental problems, this one has a simple, proven solution.
At PlanetCare, we’ve spent years developing and testing a microfiber filter for washing machines that stops these pollutants at the source. And we know: every movement for change starts with questions — real, honest questions.
Here are four we get most often — and the straight answers from the people behind PlanetCare.
We’ll let Mojca Zupan, PlanetCare’s Co-founder and CEO, take this one — because she says it best:
“I care deeply about the ocean and the planet, and I want to do my part to protect them.
But here’s the thing: I’m also lazy. I don’t want to do too much. That’s why microfibers from my washing machine are the perfect target. They come out every time I do laundry, and with just one PlanetCare filter, I can stop almost all of them.Easy. No effort. I keep nature clean, I stay lazy … and I even get bragging rights. It’s a fun talking point at parties!
If that sounds too silly, here’s the real reason: plastic pollution is scientifically, rationally, and logically bad — for nature and for us. It’s a slow, invisible poison. I find it disgusting to eat plastic — it doesn’t even have a taste! I don’t want plastic in my body, my brain, my blood, my reproductive system (yes, scientists have found it in all of those places). And I definitely don’t want to leave behind a legacy my children will blame me for.”
Microfibers may be small, but stopping them is one of the simplest and most effective ways to fight ocean plastic pollution from home.
We get this one all the time. So we asked our Co-founder and Chief Science Officer, Dr. Andrej Kržan, to explain:
“Yes — microfiber filters really work. They capture the tiny fibers that break off your clothes in every wash cycle, preventing them from entering wastewater and eventually the ocean.
In both PlanetCare lab tests and independent studies, our filters consistently remove more than 90% of released fibers. That means every load of laundry becomes a small act of ocean protection.
Of course, filters can’t solve all types of plastic pollution — but they target one of the biggest and most overlooked sources: synthetic clothing. The fibers that escape washing machines are too small to be captured later in wastewater treatment plants.
So while no single solution can ‘fix’ plastic pollution, PlanetCare microfiber filters are one of the most direct, measurable ways individuals can make a real difference.”
Science makes it clear: this is one problem where what you do at home truly matters.
To answer that, we turned to Klavdija Pavlovski, who many of you know from our installation videos:
“Yes, it’s really that easy! You don’t need to be handy or technical — you just connect the hoses, fix the holder, and you’re done. It usually takes less than ten minutes, and you’ll never need tools again.
The filter was designed for everyone — not just for people who love DIY. Once it’s installed, you can use it exactly as you would your washing machine before. When the cartridge is full, you simply replace it and send the used one back to us for recycling.
We wanted this to be something you could do once, easily, and feel proud of every time you wash your clothes. Protecting the ocean shouldn’t be complicated — and it doesn’t have to be.”
Because sustainability should feel empowering, not intimidating.
For this one, we asked Nina, who leads testing in our PlanetCare lab — and uses the filter daily at home with her young family:
“Here’s what I love most:
1. Peace of mind. I know that I’m actually doing something real for the ocean — not just talking about it.
2. Visible results. When I see the collected fibers inside the cartridge, it’s a tangible reminder that those plastics didn’t go down the drain.
3. Easy maintenance. Once the filter is set up, I barely think about it — it just becomes part of my laundry routine.And the things I don’t love?
1. Space. It takes up a little room next to the washing machine — not a big deal, but still noticeable.
2. Cartridge changes. Replacing them is simple, but I have to remember to keep a spare.
3. The reminder. Every time I see the filter, I’m reminded of how big the plastic problem really is — and sometimes that’s hard to think about.”
Her honesty sums up what this journey is really about: doing what we can, even when it’s imperfect.
💙 In the End
Our oceans don’t need heroes.
They need people — regular people — willing to make small, consistent choices that add up to something powerful.
A microfiber filter might seem like a tiny thing, but its impact grows with every wash, every household, every community that joins in.
It’s not about perfection. It’s about participation.
Because the ocean connects us all — and protecting it starts right where we are.
