Q. What sizes is Masuku One offered in?

A. The Masuku One is currently available in two different sizes, small and medium. An additional large size is under development, along with Asian and childrens sizing. 

Q. Does size S fit children?

A. Yes, the small fits children above 10 years old

Q. How do I know what size I am and how do I measure my face?

A. Please refer to the sizing chart on the product page.

Q. How is the filter made?

A. 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.

Q. Has this been tested in contact with skin? Is it dermatologically safe?

A. 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.

Q. How should it be washed and cared for?

A. 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. 

The latest government or medical advice should always take precedence.

Q. How often should I swap out the filters?

A. 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.

Q. Where is best to dispose of a Masuku One?

A. 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).

Q. What can it filter? 

A. The replaceable filter inside a Masuku One mask is optimised to FFP2 standard, meaning it has a filtration efficiency of over 94%. 

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. 

Q. How do you store the mask when you aren’t using it?

A. It’s important to store your mask in a cool, dry place between usage. Ensure the mask is protected from any potentially contaminated surfaces.
