When you buy a Bosch Microplastic Filter, you’ll not only trap up to 97% of microplastics3 but also prevent natural fibres, hair as well as detergent residues from polluting waterways. Hover over the product to discover how it works.
Don’t let what goes down the drain enter the food chain
Did you know that plastic from your laundry often lands on your plate? It’s true. Research shows that on average, we all consume some 5 g – about the size of a credit card – of the stuff per week1. Here’s how it happens and what you can do to prevent it:
Keep plastics – and our planet – out of deep water

It just works. So you don’t have to

Don’t strain yourself. Let it strain.

You’ll find that our Bosch Microplastic Filter is a tidy worker. The Active Self-Cleaning System rinses the mesh free of particles so you only have to empty the unit at most once every 6 weeks, or after a maximum of 20 cycles4.
Keeps pace with your machine load for load.

More durability equals greater sustainability. It’s why our washing machines are built to last – and so is the Bosch Microplastic Filter. In fact, the filter has the same lifespan as a washing machine5.
Consumes particles not spare parts.

Surprise! No need for supplies. You don't have to worry about buying replacement filters, cartridges or other consumables. It’s just one more way, the Bosch Microplastic Filter helps to keep your environmental footprint small.

Easy installation without fixation.
Who knew you could get attached so quickly? It’s true, you’ll love how easy it is to install the Bosch Microplastic Filter. Position it on top of your appliance, to the sides or just about anywhere nearby that’s 12 cm above ground level. And don’t worry, you won't have to use your electric drill.

No messing about
When it’s time to clean the plastic residue, you’ll get a cue. An LED light and acoustic alert ensure that even if your unit is installed out of sight, you won’t miss the memo. The emptying process is just as straightforward – scoop the filter contents directly into the bin. Just reach for the handy scraper in the lid to shift any stubborn bits.

One filter fits all.
The more people use the Bosch Microplastic Filter when doing their laundry, the better. That’s why we’ve made sure ours works with any washing machine, any programme and any laundry detergent.

More ways Bosch is microplastic-wise
Our filter isn’t the only way Bosch aims to prevent microplastics reaching bodies of water and your body. When paired with the Bosch Home Connect app, our smart washing machines can run the Less Microplastic programme. With fewer drum rotations and an increased water level in the appliance, this gentle wash reduces fabric abrasion and the shedding of microfibres by 30%6. While you can run this programme on its own, combining it with our filter is the best way to keep fibres in check.

We’ve put together the the key facts and figures for you to view at a glance, here:
- Dimensions (length x width x height): 360 mm x 165 mm x 180 mm
- Full operating power: ≤ 35 W
- Noise level: 60db (A) during self-cleaning (10 sec x ~3-5 per cycle)
- Recyclable materials: 69% of the input materials are recyclable
When well maintained and regularly emptied, your filter is designed to last for the same lifespan – or number of laundry cycles – as our washing machines. No replacement cartridges are needed.
Since the filter comprises 69% recyclable materials, it can be used to create new products.
Connecting the Bosch Microplastic Filter to your washing machine is simple enough to do yourself. You don’t need screws, bolts or nails to fix it and can position it almost anywhere around your washing machine as long as it’s between 12 and 100 cm above ground level.
The filter will work with any washing machine brand and can even be fitted to older appliances.
