GUPPYFRIEND Washing Machine Filter

The GUPPYFRIEND Washing Machine Filter is already used at sports clubs and in many households. For the next round of production, we are only making as many units as we have pre-orders for. Interested? Then get in touch via our contact form or send us an email to us@guppyfriend.com.

The close-meshed fabric, originally used for drinking water filtration, is a highly effective solution. Therefore, you can filter your wastewater with the GUPPYFRIEND Washing Machine Filter Starter-Set. Its effectiveness is owed to the extra-large drainage area of the round filter cartridge. Due to the absence of a "bypass," the water must inevitably flow through the filter. Don't worry: if you don't remember to clean the filter in time, it won't overflow. Your washing machine will stop the washing program automatically.

 

We implement an efficient and proven method from the drinking water supply sector for exceptionally high effectiveness. This system has been applied to private homes for decades. The mesh size differs in the two or multi - filter systems to keep even the smallest particles out of the wastewater reliably. Our GUPPYFRIEND Washing Machine Filter Plus-Set uses filter cartridges of different mesh sizes, one following the other. This way, even the smallest microplastic particles will be filtered out.

However, even though our GUPPYFRIEND Plus-Set didn't let any fibres past our filter in the laboratory tests, it is unacceptable to speak of a 100% retention rate as small amounts of microplastic fibres may have disintegrated into micro-fragments that can barely be detected under a microscope. This is precisely why it is essential to reduce the use of synthetic textiles and to pay attention to the quality and durability of your clothing.

The GUPPYFRIEND washing machine filter can be installed in any standard washing machine for normal domestic use. The filter requires a small space and can turn you into a real "Greenwasher" in no time.

 

Both Starter- and Pro-Set are compatible with any washing machine.

Depending on the location and pumping capacity of the washing machine, it may be necessary to increase the water pressure to aid wastewater filtration slightly. For this purpose, we recommend a water pump connected before the filtration unit.

With the Starter-Set, particles larger than 150 µm can be retained. Most fibres in washing machine wastewater are generally much longer. Due to the flexible nature of the fibre, it sticks to the filter instead of poking through the mesh opening like a needle. Thus, our test trials show that few threads end up in the wastewater even when using the Starter-Set. With the introduction of the second cartridge in the Plus-Set, fibres (>50µm) that have passed through the first filter (Starter-Set variant) due to their size or shape are now also retained. In our tests, this corresponded to up to 10% of the total amount. 

 

Regarding the effectiveness and function of filters, the result, to a large extent, depends on each case. This means we continually test the GUPPYFRIEND Washing Machine Filters practically, i.e., with conventional washing machines, detergents, and washing loads. Because different textiles lead to different results. But one thing is sure: With the GUPPYFRIEND Washing Machine Filter, Washing Bag, and Detergent. You are ideally equipped against microplastic pollution. If you also follow the rules of our Washing Guide and choose your clothes consciously, microplastics won't stand a chance.

Please note that we have developed our washing machine filters for use in normal households. Our filters are not designed for washing very dirty textiles such as cleaning cloths and rags. For very dirty laundry, the time and effort required to clean this type of filter would be very high. We offer customised solutions for this kind of application.

After each wash, open the draining tap and let the water out into your house drain. Please use the fine sieve we enclose while doing this. You can dispose of the captured deposits in your residual waste. Then close the drainage tap again. That's it.

Cleaning the filter cartridge is a different matter. This depends on the textiles and the composition of your wash load, the degree of soiling, the choice of detergent, and a few other factors. Through the transparent housing, you can see when filter cleaning is necessary. As a rule, cleaning the filter element with the provided brush, approximately every fifth wash should suffice. Remember, make sure that the housing is tightly sealed after reinsertion.

Tip: With the GUPPYFRIEND Washing Bag, your clothes will last longer and reduce filter cleaning intervals because you already efficiently avoid microplastics in the drum.

Yes. A plumber is not necessary. If you can assemble an IKEA cabinet, you can do this, too. However, it would help if you had a few tools ready: A cordless drill, a stone/wood or metal drill (recommended: diameter 6 mm), depending on the nature of the wall—a screwdriver, and something to mark the holes, a tape measure/meter stick/ruler. A spirit level is also helpful; you can find all this information in our instructions.

The GUPPYFRIEND Washing Machine Filter makes the invisible visible. So, through the transparent housing, you can easily see the damage you have protected nature from. After just a few washes, the grey plastic fibre sludge on the filter cartridges is visible. This allows you to recognize in time when to clean the filter cartridge. The frequency of cleaning depends on many factors, such as the composition of your textiles or their degree of soiling.
