    • Particle Filtration Efficiency >98%

    The PRO mask uses a unique triple filter system.

    The first layer of the filter system catches larger pollution particles such as dust and PM10. It’s then backed up by the Three-Ply Micro Particulate which stops nearly 100% of smaller particulate matter such as PM2.5 and PM0.3.

    The inner filtration layer is made from 100% pure activated carbon cloth, originally developed by the UK Ministry of Defence for chemical, biological, and nuclear warfare protection.

    The carbon filter is treated with silver to ensure 99% of harmful pathogens are removed and killed.

    This multi layered  filter system means the Cambridge Mask performs better and lasts longer than other masks on the market.

      The PRO Mask can be used for up to 340 hours depending on the level of pollution it is exposed to.

      For the average customer this is around 3-6 months of wear. The mask can be washed with soap and hot water, however, keep in mind that this will not extend the life of the filters.

      The Churchill is my best choice

      For a mask hater, this one is bearable. My hearing aids don’t get entangled and my earrings stay in place, except for the very long ones. Leave those home!

      Quality is lacking

      I’ve been ordering these mask since 2020 and have always been satisfied with the masks. The last two orders I’ve placed, I’ve received masks that are too large, from what I’m used to, and the adjusting elastic is old and breaks apart when you pull on it. I’m going to have to find a different supplier. Sorry Cambridge, your quality isn’t what it used to be.

      Perfect!

      We have an immunocompromised family member. Covid may be ‘over’ for some people, but we still wear our masks everywhere.
      Thank you Cambridge for making well fitting, functional, comfortable excellent filtration for our family.

      The elastic is dry rotten and broken.

      I just purchased and was wearing the first time. The elastic in the straps is dry rotten. Not going to lie. I am shocked and appalled. I really needed this mask and now have a defective one. I would not recommend at all.

      Great—for the only XL Pro mask available

      I love the Cambridge Churchill Pro Mask. Not because black is my favorite color, but because it is the only Pro mask available in XL—for over a year. I would love to wear grey, or blue, or even green! But not for XL! I would also like to wear a non-valve pro, but they haven’t been available in solid colors in over a year. Oh well.
