Design of Mask Body
The Dartex material used in our masks is designed as a medical grade fabric to come into contact with human skin without causing an allergic reaction. It has a double sided construction which ensures a soft fabric surface against the skin whilst outside it is a wipe down polymer surface. It has a good degree of elasticity and is lightweight.
Design of Replaceable Filter
The 0.3 micron filtration system is intricately designed with a filter material that has been manufactured by blending, pressing, fulling and drying, to produce a non-woven homogeneous mat of fibre. This material is processed to ensure the perfect thickness and overall shape to fit inside our purpose made injection moulded filter housing. Tests prove that our 0.3 micron filters working at 95% for 10 microns particles and 99% for 15 micron particles.
All of the materials used in the construction of the mask are able to be readily disinfected to ensure continued protection from airborne infections. It is recommended that the mask body and filter housing are cleaned with an anti-bacterial spray daily when the filters are removed, binned, and replaced.
Helps Reduce Spread
The design using a twin filter inlet ensures that the main facial area of the mask remains uncontaminated. This means that when the user touches their facial area they are not helping to spread the contamination. This is especially evident with children, who are used to putting fingers in their mouths etc.

Fractional Efficiency Measurement using a Solid Particulate Aerosol
Two strips of filter media, with face dimensions of 255 x 60 mm, were installed adjacent to each other inside a holding frame. The holding frame was installed in a horizontal test duct and exposed to a controlled test aerosol containing mineral silica dust. An optical particle counter was used to take seven upstream and six downstream measurements of particle concentration. The test conditions were as follows:
|Test Air Flow Rate||20 Nm³ / hr|
|Dust Grade:||B8 Over-Size ( batch number 9491 )|
|Concentration:||0.1 g / m³|

Current Standards for Face Masks
The two main standards used to produce masks are:
BS EN 14683 for Surgical masks
BS EN 149:2001 for Particle masks
Surgical masks are designed mainly to prevent contamination from the wearer to the patient, and also to protect the wearer from potential splatter of fluids from a patient. They are not effective at giving any protection from breathing in airborne particles as they do not fit tightly and unfiltered air can be breathed in from around the sides of the mask.
Particle masks ( P1-P3) are designed primarily for industrial use and are designed to capture very small dust particles, down to 0.3 microns in size. The issue with giving P3 masks to people is that unless they have been trained how to fit the masks then they are generally not effective as they can breath in from around the sides and thus breath in unfiltered, possibly contaminated, air.
It is recommended by the government that people use FFP3 masks. These are disposable masks that capture particles down to 0.3 microns. The actual Coronavirus is actually 0.01 microns so no openly available mask can capture this size of particle.
When people cough and sneeze they produce a spray of bodily fluid, which is what the virus sits on to be transported. This spray is referred to as an aerosol and made up of droplets that range from 100 microns down to 15 microns. The large droplets quickly drop to the ground but it is the small 15 micron droplets that float around from up to 5 minutes that are the focus for filters.
Filter Testing ISO 16890
When we asked advice from various test houses about filter standards it was explained that BSEN 149 focus was 90% on the fitting of the mask and the remaining 10% on the fitration. This was not suitable for the BM design. It was suggested that we focus on the filter testing and use the newly updated ISO 16890 standard for filters. This actually has a section that focues on filtration of viruses and nanoparticles. This was deemed much more relevant to the design of the product than tiny dust particles created during various industrial processes. Below is a summary of the ISO 16890 standard:-
ISO 16890 GROUP CLASSIFICATION
- ISO ePM1 : ePM1 min ≥ 50% ( viruses, nanoparticles, exhaust gasses)
- ISO ePM2,5 : ePM2,5 min ≥ 50% ( bacteria, fungal and mold spores, pollen, toner dust)
- ISO ePM10 : ePM10 ≥ 50% (pollen, desert dust)
- ISO Coarse : ePM10 ≤ 50% (sand, hair)
With the introduction of the new ISO16890 standard, actual operating conditions will be more effectively taken into account. Instead of considering only the particle size 0.4 microns (EN779:2012), as previously, a broad range between 0.3 microns and 10 microns will be used to determine separation efficiencies for particulate matter fractions PM10, PM2,5 and PM1 (ISO 16890). In order for an air filter to be rated to PM1 or any of the other PM sizes it will need to demonstrate a minimum efficiency of 50% and this will be recorded incrementally to the closest 5% – so an air filter performing at 66% to PM1 particles will be rated at ePM1 65%. For coarse filters the new standard will include filters that capture less than 50% of particles in the PM10 range –these will be known as “ISO Coarse” and will detail their PM10 performance i.e. “PM Coarse 45%”.
Filter Test Results
The test house that carried out the filter testing was PARTICLE TECHNOLOGY LTD
They tested the filter material with eight different particle sizes ranging from 15 microns down to 0.75 microns.
The summarize the results:-
15 microns 99.7% of the particles were removed from the air.
4.8 microns 97.5% of the particles were removed from the air.
0.75 microns 76.8% of the particles were removed from the air
Conclusion of Results
The testing has proven that the filters exceed the highest levels set with ISO 16890 and can be classified as ePM1 compliant.
- Flexible Nose band
- Ear Loop
- Replaceable Filters x2
- Size Adjuster
Changing the Filter
Take mask out of packaging and bend open the nose band to enable mask to fit over your face. Push the black filter housings out by pushing on the four holes on the inside of the mask. Ensure both sides are removed. Bin any used filters immediately.
If the mask has been worn and you are replacing the filters then ensure you clean the mask and your hands before touching the new filters. The mask fabric will withstand machine washing or anti-bacterial spray cleaners etc.
Place a single filter into each filter housing, ensuring that they are sitting central and flush.
Carefully insert each black filter cap into the clear filter holder on the outside of the mask. Ensure that the black filter caps are pushed in fully so that they are flush with the filter holder, or they may drop out.
The mask is now ready to be fitted to your face.
FILTERS SHOULD BE CHANGED DAILY
Fitting the Mask
There are two adjusters, one on each side. These enable the mask to be adjusted to fit snugly to your chin and cheeks. Lift the mask up to your face and loop over each ear.
Make sure your mask covers your chin and your nose.
Bend the nose band so that it meets the shape of your nose.
Breath in and out. If the mask bellows in and out as you breath then it is fitted tightly enough.
If when you breath in air is coming in from around the cheeks then adjust the side clip by looping the holes on the ear loop strap over the T baron the adjuster clip.
If air is coming out of the top nose area then squeeze the nose band tighter to your face contours.
PLEASE NOTE THAT FACIAL HAIR PREVENTS EFFECTIVE OPERATION
It is recommended that the mask is cleaned on a regular basis. This can be done in one of several ways. The mask is made from a material known as Dartex® which is manufactured for use on medical products so they cover many cleaning options.
Be assured that the properties of your Dartex® mask fabric provide the optimal barrier to prevent the spread of infection:
- Impermeable to bacteria, viruses and fluid ingress – polyurethane is a fluid-proof, breathable barrier.
- Safe for skin contact.
A standard anti bacterial cleaner / wipe can be used to clean the shiny outer surface of the mask. It is recommended that this is done on a daily basis when the filters are changed.
The NHS lays out some guidelines that you may want to wash items that are contaminated separately, at a higher temperature and with a bleach-based detergent – such as a biological powder for whites.
The Dartex® fabric can be washed at temperatures upto 90 degrees Celsius.
Surgical Masks vs. Respirators
There are two different types of masks: surgical masks and respirators.
A surgical mask is a disposable medical device that can be bought in pharmacy and that protects against infectious agents transmitted by “droplets.” These droplets can be droplets of saliva or secretions from the upper respiratory tract when the wearer exhales.
If worn by the caregiver, the surgical mask protects the patient and his or her environment (air, surfaces, equipment, surgical site). If worn by a contagious patient, it prevents the patient from contaminating his or her surroundings and environment. These masks should not be worn for more than 3 to 8 hours.
A surgical mask can also protect the wearer from the risk of splashes of biological fluids. In this case, the surgical mask must have a waterproof layer. It can also be equipped with a visor to protect the eyes.
But a surgical mask does not protect against “airborne” infectious agents so it will not prevent the wearer from being potentially contaminated by a virus such as the coronavirus.
A respirator is personal protective equipment that prevents the wearer from inhaling aerosols (dust, smoke, mist) as well as vapors or gases (disinfectants, anesthetic gases) that are health hazards. Unavailable in pharmacy, it protects the wearer from airborne infectious agents i.e. against contamination by a virus such as coronavirus, SARS, H1N1, etc.
Respirators are divided into two categories: insulating and filtering. Filtering respirators consist of a facepiece and a filtering device. Sometimes the filter element is integrated into the facepiece. Depending on the type of filter, the mask will either be effective only against particles, only against certain gases and vapors, or against particles, gases and vapors.
Filtering respirators can sometimes also be equipped with an exhalation valve to improve user comfort. The valve prevents condensation inside the mask, misting on the glasses and helps the user breathe in and out easily.
It should be noted that respirators also protect those who wear them from inhaling “droplets” of infectious agents. Respirators can be disposable or reusable. In the second case, it is possible to replace the filter when it is full.
What are the Standards ?
Each of these two types of masks is subject to different standards and regulations depending on the country or geographical area.
Surgical masks are tested in the direction of exhalation (from inside to outside). The tests take into account the efficiency of bacterial filtration.
In Europe, they must comply with the European standard EN 14683, which has 3 levels of bacterial filtration efficiency (BFE1, BFE2, Type R). In the United States, they must respect ASTM standards which have three levels of protection (from low risk of exposure to fluids to high risk of exposure to fluids).
Respirators are tested in the direction of inspiration (from outside to inside). The tests take into account the efficiency of the filter and leakage to the face.
In Europe, they must meet the European standard EN 149: 2001 which has three classes of disposable particulate respirators (FFP1, FFP2 and FFP3).
FFP1 refers to the least filtering of the three masks with an aerosol filtration of at least 80% and leakage to the inside of maximum 22%. This mask is mainly used as a dust mask (home renovations and various types of work).
FFP2 masks have a minimum of 94% filtration percentage and maximum 8% leakage to the inside. They are mainly used in construction, agriculture, and by healthcare professionals against influenza viruses. They are currently used for protection against the coronavirus.
FFP3 masks are the most filtering mask of the FFPs. With a minimum filtration percentage of 99% and maximum 2% leakage to the inside, they protect against very fine particles such as asbestos.
In the United States, respirators must meet NIOSH (National Institute for Occupational Safety and Health) standards. Within this standard, there are several classes of respirators depending on the degree of oil resistance:
Class N: no oil resistance. A distinction is made between N95, N99 and N100. The number after the letter indicates the percentage of filtration of suspended particles.
Class R: mask resistant to oil for up to eight hours. Here again, a distinction is made between R95, R99 and R100.
Class P: a completely oil-resistant mask. There are also P95, P99 and P100.
Should a Disposable or Reusable Mask be Used?
Surgical masks are disposable medical devices that must be disposed of in the appropriate manner after use. Respirators (FFP / N, R or P) can be disposable or reusable. In the second case, it is possible to replace the filter when it is full.
The effective life of a surgical mask or a respirator is indicated by the manufacturer. It varies according to use. Generally speaking, it can range from three to eight hours depending on the concentration of the contaminant and a series of external factors such as air humidity, temperature, volume of air breathed in, etc.
For respirators equipped with gas filters, if the wearer begins to perceive the smell of gas, he or she must immediately leave the work area and replace the filter. Similarly in the case of dust filters, if the wearer begins to perceive an increase in inspiratory effort, he or she should leave the premises and replace the filter. These masks are mainly worn by people working in contact with chemicals or by firefighters.
