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. While we were able to test it only down to 300nm particle sizes, we achieved filtration efficiencies as high as 99.95%.It also means, 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.
