More than a Filtration system
Kills Bacteria & Viruses at the Mask Surface
The CleanShield innovative washable antimicrobial mask introduces a ground breaking protective personal shield against all forms of air pollution, bacteria and viruses. Utilizing the very latest Titanium Dioxide (Ti02) with cuduped Silver nanotechnology the mask surface provides the capability to kill bacteria and viruses at the masks surface layer prior to entering the masks filteration system.
"Based on antimicrobial test results CleanShield Face Mask shows very strong and long term antimicrobial activity with almost 100% antimicrobial effect." Danish Technological Institute
Using our high-grade activated carbon fibre and patented German particle mesh filters, combined with a double layer of Titanium Dioxide (Ti02) and Silver (Ag) coated surface technologies, the CleanShield face mask provides the ultimate premium protective antimicrobial mask on the market.
Laboratory tests have proven little degradation (<5%) of the mask filtering system to continuously protect the user after washing. Based on normal domestic use, CleanShield suggest the mask life should provide around 75+ mask wearing days usage based on 15+ washes and a recommend washing cycle of every 5 working days (based on an average 2-3hrs usage per day).
Important: If the mask is damaged in any way, it must be replaced immediately. (Contact us for a stockist near you).
Layer 1 - Unique permanent surface coating - anti-viral & anti-bacterial coating
In laboratory tests: "CleanShield Face Mask surface shows very strong and long term antimicrobial activity with almost 100% antimicrobial effect. Acts effectively against viruses and other organic specimens and pollutant". Danish Technological Institute
Continuously eradicates bacteria & viruses contact with the mask surface when your mask is exposed to light
Approved Certificate of conformity to ISO 22196:2011 & ISO 20743:2013
Layer 2 - Advanced Activated Carbon Filter
Helps in purifying the air for better user safety
Typical activated carbon filters remove solid particulates (ranging from 0.5-50 μm) such as dust, pollen, mould, and bacteria from the air. Filters containing an adsorbent or catalyst such as charcoal (carbon) may also remove odours and gaseous pollutants such as volatile organic compounds or ozone. source: wikipeadia

Layer 3 - P2.5 Non-Woven Melt-Blown Fabric Filter
Filters out fine pollution particles – including pollen, soil and dust particles including:
- Nonwoven melt-blown fabrics are porous. As a result, they can filter liquids and gases. Nonwoven melt-blown fabric is an essential material for face mask. source: Wikiperia
- This layer stops around 98% penetration of fine particles and will also serve as an additional anti-bacterial & anti-viral filter
Layer 4 - Electrostatic Mesh
This patented German manufactured protective layer is charged by air friction being activated by both inhaling and exhaling air movement.
This layer stops at least 99.95% penetration of fine particles and will also serves as an additional anti-bacterial & anti-viral filter.
Layer 5 - Soft Cotton Fabric
For better wearer comfort and easy breathing.
virus and bacterial reading of 0.05% at this level provide exceptional protection
(proven by two independent laboratory reports)
A unique first layer of protection
Anti-Bacterial and Anti-Viral
The CleanShield face mask surface is treated twice with CleanShield proprietary titanium dioxide (TiO2) and silver nanoparticle technology that forms a permanent, anti-bacterial, anti-mould, transparent thin film on the mask surface.
This permanent CleanShield mask coated layer is a photocatalyst that once activated by light, develops oxidative properties on the mask surface that continually breaks down and kills harmful organic bacteria, viruses, and mould spores.
The mask can also kill and decompose bacteria and viruses in the surrounding air because of air flow from exhale breathing.
Recent laboratory tests based on antimicrobial effects of the CleanShield Face "Mask shows very strong and longterm antimicrobial activity with almost 100% antimicrobial effect."
Current lab results received for CleanShield Surface Coating (Oct 2020) also show a 96.2% breakdown of virus tested and 100% bacteria within 1 minute of contact with the surface.
Global laboratory testing shows the effectiveness of titanium oxide (Ti02) and silver surface coating is highly effective against the blood-borne viruses including HBV, HCV and HIV as well as against members of other virus families such as orthomyxoviridae (incl. all human and animal influenza viruses like H5N1 and H1N1), coronaviridae (MERS-Cov & COVID-19) and filoviridae including Ebola virus.
Patented Particle Filter Technology
CleanShieldfFace masks are layered with CleanShield patented German manufactured electrostatic protective meshes.
The meshes are charged by air friction (inhaling & exhaling breath) that aid in positively reducing the penetration of incoming fine airborne particles, bacteria, and any other noxious particles.
CleanShield surface mask coating can absorb some UV light and protect the surface from the UV damage.
The antistatic feature can reduce static adsorption caused from movement of air and from small airbourne dust particles and polution.
The particle filtration efficiency of CleanShield washable face masks have been fully tested by the Danish Technological Institute using a DEHS1 aerosol test utilizing a SMPS measuring system resulting in a particle capture concentration and size distribution in the range from 7 Nm to 673 Nm (Covid-19 particles are around 60-149 Nm – ref: WHO).
Further testing of the effectiveness of the masks to remove particles was measured before and after hand washing using 30 °C and 40 °C water. The results did not alter the capability of the mask filtering system. Additional hand wash testing (washing the masks) was conducted between 15 times at 40 °C. The results proved only a slight (<5%) degradation in the efficiency of the masks to continue to remove particles under the same aerosol testing.
Washing either by hand or using 30 °C or 40 °C water did not appear to alter the efficiency. Also, we could not document a change in efficiency after washing fifteen times at 40 °C.
Aug 2020: Recent laboratory testing of the CleanShield unique mask surface coating technology confirms that the mask will continuously decomposes and kills bacteria and viruses when exposed to a light source (natural or artificial).
