Cambridge Mask Promo Code February 2025 - 70% OFF

Cambridge Mask, after N99 testing, instead of the next level of N95, uses a unique three-layer filtration system to filter out dust, PM10, PM2.5, and PM0.3 contamination particles as well as bacteria and viruses. The first layer captures large polluted particles such as dust and PM10, and the second layer is a three-layer particulate filter that intercepts nearly 100% of smaller particles such as PM2.5 and PM0.3. The last layer was developed by the British Ministry of Defence to filter out viruses, bacteria and gas pollution such as volatile organic compounds (VOCs), ozone, phenyl sulfide and formaldehyde. Cambridge Mask is treated with silver, which means it blocks and kills 99.77% of the airborne microorganisms. Its TMN99 tested filter is silver treated to kill and block 99.6% of the virus. Contaminated clouds contain liquid particles and gases that are captured by the particle layer and completely absorbed by the military carbon layer.
