Installation Instructions

Compatible with all masks. Position inside your mask's pocket or place between between the mask and your face


Dispose after 1 day of use.


A Suregard Bacterial/Viral Filter Insert does NOT guarantee filtration of microscopic virus particles when used in a mask. This is dependent on the fit and seal of the mask and the fit and seal of the filter insert against your face.

*BFE (Bacterial Filtration Efficiency) and VFE (Viral Filtration Efficiency) tests using Staphylococcus Aureus (*ATCC #6538) and bacteriophage PHI X174 (*Dimension about 0.025 ). Coronavirus species range in size from 0.06 to 0.2.

How often should I wash the mask?
Once a week when in use, or daily if you're sick.

Can I wash the mask in a washing machine?
Yes, ideally in a delicate wash to preserve it's longevity.

How long will the mask last?
The masks should be used until it no longer seals across your nose bridge and chin securely.  This will vary from person to person and will also be dependant on the amount of use and care taken with the mask.

Will this mask stop me from catching a virus or from getting sick?
This mask on its own offers protection from dust, pollutants and liquid droplets.
With the Suregard filter insert added, the masks has added Bacterial/Viral protection.
Masks decrease the likely chances of your mouth and nose coming in contact with hand cotangents and droplets from the environment, especially when other people are talking in close proximity.   
However note, no mask can 100% guarantee filtration of microscopic virus particles. A mask is most effective when combined with good general cleaning and hygiene habits such as regular hand washing and not touching your face directly after being in contact with potentially contaminated surfaces. 

What is the Suregard filter material insert and how effective is it?
The Suregard filter material insert is a medical grade Tec200Gram electrostatic bacterial and viral material which is regularly used for clinical applications to prevent cross infection in the hospital setting. This filter material has been independently shown to filter up to 99.9999% of all bacteria and viruses in some of the hospital products that utilise this filter material for ventilation and lung function testing. 

Does the mask come with the filter inside?
The mask does NOT include the Suregard filter insert as standard. The Suregard filter insert is an added level of filtration which is optional. These filter inserts are available with the mask as a kit, or separately.

How often do I need to replace the filter?
As per their usage in the hospital and clinical environment, these filters are considered single patient disposable. So we recommend they're replaced regularly for optimal infection control measure.

Can I wash the filter?
No. The filter is medical grade hydrophobic material designed to trap pathogens. They do not wash in water and melt if heated. 

What is the cap on the front?
The cap on the front is a one way exhalation port. It allows you to exhale, but closes off during inhalation to reduce the direct flow of air in close proximity.
