The Masuku One is currently available in two different sizes, small and medium. Please refer to our Masuku One Size Guide.
Yes, the small fits children above 10 years old
Masuku’s patented nano-fibre filtration material is created from a newly developed electrospinning process involving an engineered compostable polymer. Compared with melt-blown fibres or simple fabrics, which are used to make the vast majority of face masks currently available, the electrospinning process is able to create a highly uniform membrane consisting of extremely fine fibres (up to 1,000x narrower than a human hair) dispersed with extreme precision for maximum material efficiency.
The filtration membrane provides strong protection from dangerous particles in the air, including pathogens, allergens and pollutants. This is all made possible through a combination of manufacturing processes and bio-based filtration technologies that Masuku has developed. We designed filters to fight the smallest particles out there, such as viruses. We are able to filter urban air pollution, pollen, bacteria, and fibres by any product. Smells have different mechanics and sizes when they travel in the air, and you will still smell any odour, it applies to any product out there.The replaceable filter inside a Masuku One mask is optimised to a similar level of FFP2 standard, meaning it has a filtration efficiency of over 94%.
Face masks can help slow down the spread of the virus. This is in addition to other preventive measures, such as getting vaccinated, frequent hand-washing and social distancing.
Coronavirus can spread through droplets and particles released into the air by speaking, singing, coughing or sneezing. The Masuku One is snug over the nose, mouth and chin, with no gaps. This closed cup design seals the air coming out from under the edges of the mask, ensuring maximum protection.
To ensure optimum performance of your Masuku One, change the filter regularly. Over time, the filter will become saturated and start to lose function. Each Masuku One comes with 3 filters, plus one already installed. We expect the average user to require 10 filters each month.
This varies greatly depending upon location (i.e. levels of ambient air pollution) and personal usage patterns.
For example, two people in central London would need to replace the filter at different intervals depending upon whether they commute by tube, bicycle or car; whether they work on a construction site or in a well-ventilated office.
As a rule of thumb, we expect the average person using the mask on a daily basis would need to change their filter every three days.

The key technology of the Masuku mask is its biodegradable filter layer. We have worked hard to develop a materials solution to overcome the issue holding back conventional melt blown polyester filters.Our solution is to use a bio-based polymer mesh using PHB. This filter layer is deposited onto a viscose substrate. This means that both the filter and the mask material can be disposed of as compostable waste. We are undertaking a number of certification test programmes relating to biodegradability/compostability and once in place will allow us to recommend that the filters are home composted as the most responsible means of disposal.
Yes, all textile components have been tested for hazardous dyes and auxiliaries. The guard material, which is the main point of contact with the skin, is OEKO-TEX® certified.
Under everyday circumstances in typical urban environments, we recommend using gentle hand wash.
1. Use mild gel detergent or hand soap and warm water to create a lather.
2. Gently rub the cover and earloops for a minute, then rinse under running water until all suds are removed.
3. Allow to dry at room temperature laid flat.
Never bleach, tumble dry, dry clean or iron.
The frame can be handled the same way, or using an alcohol based wipe.
It should be washed at least twice a week if you are using the mask for longer periods of time.
The latest government or medical advice should always take precedence.
The Masuku One is not recommended to be folded and stored in your pocket. This can cause too much strain on the plastic frame, and ultimately cause damage to the product.
Firstly, separate the components. The frame is made from 100% HDPE and is marked with the HDPE recycling logo. It can be placed in a recycling bin, along with the outer fabric which is 100% PET, as marked by the label. The filters are made from a biodegradable polymer and are designed to be compostable (certification pending).
It’s important to store your mask in a cool, dry place between usage. Ensure the mask is protected from any potentially contaminated surfaces.
If well cared for this product should last anywhere up to several years. As we designed the components to be modular, you can refresh individual parts as needed.
COVER: Outer 100% recycled polyester, guard 100% polyester
FRAME: HDPE TRIMS (A-ring/adjuster): POM
EARLOOPS: 79% recycled polyester, 21% recycled elastane
FILTER: Viscose substrate/PHB membrane.
All parts are currently manufactured in China, where the majority of products are made. The outer cover fabric is from UK for launch batches, but we have resourced alternatives locally to Chinese factories. Filter material is currently manufactured in Germany/Czech Republic but will be manufactured in the UK. We are looking for ways to reduce carbon footprint and source more locally in Europe.
The Masuku One is manufactured in the UK.
Plastic is a high performance material, is easy to disinfect and is cost effective. It has a smaller environmental impact in comparison to most textile fibre types.
All the materials that are exposed to skin have standard 100 OEKOTEX certificate which means you can be certain that they are tested for harmful substances and are harmless for human health. General guidance must be followed. If you have an allergy, use at your own risk.
A single day is suggested per each mask, considering non-highly hazardous environmental conditions. Otherwise we would say 3 hours. If the products get wet, we do not recommend drying and reusing it.
You can dispose of it at the end of the day, until then you can store it in anyway you are used to with other products. However, try to not damage it mechanically or overstretch it to the point of breaking it.
No, the earloops tapes are made from natural rubber and biodegradable nylon.
Material: 47% natural rubber / 53% Biodegradable Nylon
We are currently conducting testing with industrial composting authorised facilities to identify right disposal routes to provide guidance. Due to potential concerns of contamination by viruses, we would advice to dispose them with general waste at the moment. We are working on creating a process flow on how customers best dispose and what happens if they don't do this (end up in nature or general waste). Full results will be given upon rest results. As a rule of thumb, components degrade slower in water.
If it is put in general waste, it will most likely will end up in the landfill. Here it will probably biodegrade over a period of time. The majority would get incinerated.
No, the straps will not need removing before disposal. If you remove the earloops, the base might degrade quicker, this is what we are currently testing. It might be a recommendation for future, but not a requirement as yet.
The natural rubber and the biodegradable nylon yarn that covers it are designed to biodegrade within 3-5 years. The main body of the mask has been tested in soil under aerobic biodegradation conditions and has shown 100% degradation after 46 days leaving no harmful or toxic residue in the soil. We are currently working on identifying the best practise and route of getting these masks as a whole to biodegrade most effectively.
This means that it does not require industrial composting, and will biodegrade in natural environments, e.g. home composting - We want the products to degrade in soil and marine/water environment, as some biodegradable materials are usually limited to only some of known environments.
You wouldn't need to bury them but it would help speed up the degrading process.
Single use masks that end up in nature will harm wildlife and pollute waters as they contain plastics (often PP, polypropylene). Compared to Masuku Daily, these type of masks can take up to 450 years to break down into microplastics depending on UV/environmental conditions.
We have selected bio-based polymer, generally used by bacteria’s as an energy storage, that is prepared by methods of dissolving in solvents, that are electrospun into homogeneous nanofibers under ultra-high voltage.
The Masuku Daily will eventually breakdown into smaller particles and biodegrade usually within a couple of weeks. This is still to be tested and verified in different environmental conditions such as in water, in direct UV and in soil. PHB degrades rapidly, whereas viscose, noseclip, rubber and bio nylon breaks down a little slower, but still within about 5 years. Bio clip will degrade into bio-mass.
Majority of product composition is sourced from Germany.
Our DIN Certificate proves that the Masuku Daily is made up of 73% Bio-based Carbon Content. The Certificate can be found here:
