Cambridge Mask Pro – The N99 Pro Mask

Cambridge Mask Pro is a fashion focused pollution masks that come in a range of patterns and 5 sizes to fit children and adults.

The filters used in Cambridge Mask Pro meet the N99 Standard (higher than N95). This is a US Government specification for pollution masks. The masks use a triple-layer filter which will protect from a range of airborne contaminants.

British Made. Military Grade

Cambridge Mask™ masks are N99 tested as opposed to the next level down, N95 and filter out dust, pollution particles such as PM10, PM2.5 and PM0.3 as well as bacteria and viruses using a unique triple layer filtration system. The first layer catches larger pollution particles such as dust and PM10, followed by the Three-Ply Micro Particulate Filter which stops nearly 100% of smaller particulate matter such as PM2.5 and PM0.3. The last layer has been developed by UK’s Ministry of Defence and filters out viruses, bacteria and gas pollution such as Volatile Organic Compounds (VOCs), Ozone, Benzathine and Formaldehyde.

• Cambridge Mask™ is N99 tested and has been treated with silver, which means it blocks and kills 99.77% of micro particles such as airborne bacteria.
• Cambridge Mask’s™ N99 tested filters have been treated with silver to kill and block 99.6% of all viruses.
• Pollution clouds contain liquid particles and gases, which are trapped by the particulate layer and fully absorbed by the military carbon layer.

Long Last Filter and Washable Mask

The mask can be used for up to 340 hours depending on the level of pollution it is used in. For the average customer this is around 3-6 months of use.

The mask can be washed with soap and hot water, however keep in mind that this will not extend the life of the filters.

Can the mask be washed?

The mask can be hand washed with Soap and hot water, however this will not extend the life of the filters as the pollution will be locked into them. As the whole mask is the filter, when past its useful life a new mask is needed. Please do not machine wash or dry the mask.
