The PRO Mask

Cambridge Mask PRO Admiral CE Mask

Cambridge Mask PRO is a fashion focused pollution mask that comes in a large range of designs and 5 different sizes to fit comfortably for both children and adults.

The masks use a triple-layer filter which protects the wearer from an extensive range of airborne contaminants.


What’s In The PRO

British Military Grade Filter

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.

    I just received my order of 6 Admiral Pros and I am very pleased. Even though they took some time to get here due to COVID 19, Cambridge Mask Co kept in regular contact to let me know the status of the order. The order came a little earlier than they said it would and the Admiral Pro is very comfortable and breaths easily compared to other N95 or N99 type masks. I like how it is adjustable and reusable. Thank you Cambridge Mask Co.

    I have tried numerous masks previously, and none of them really fitted very well. On top of that, my glasses would constantly steam up every time I exhaled. I had been hesitant in getting a valve mask as their are lots of media reports that you are sharing the virus (if you have it) through the valve. As every mask I have tried exhales air through the sides and the top of the mask anyway, I thought, what’s see the difference?

    When the Cambridge Mask arrived I was wow’d. This clearly is a high quality product and well thought through. The mask fitted well around my face, however the loops go well beyond the back of my ears. I didn’t spot the strap initially (and their is no mention of it in the user manual) but that worked an absolute treat. The mask is comfortable, it is sealed on my face, and there is less air escaping through the valve than there was around the side and top of all the previous masks I have tried.

    Really happy with this product and just bought another 2 !!!! Thank you Cambridge Mask Co.

    I like the mask very much and do feel safer wearing it. Top marks on product design and execution – especially the carbon barrier! Customer service, however, needs to improve, they did not do what they confirmed in the chatbox: a simple request to correct the spelling of a surname for a gift mask I was sending to a friend was not corrected as agreed on the shipping confirmation: I was told directly that it was changed and updated. A footnote to a great mask, but very disappointing after having ordered three of them now, two as gifts for friends. Cambridge – please tighten up your ship! If there are problems on such a simple request, the rot must be setting in!

    The mask would be good if it had a different type of strap to keep it on. The ear loops are way too wide and cause the ears to pull forward and make it impossible to keep a proper seal for the mask. The closest I could come to making the mask fit somewhat secure was using the adjustable strap and having that under my ears without anything on my ears at all, but that still causes a less than ideal fit. I also took one mask, and cut the ear loops, then sewed on a system to tie it to my face. That worked as well but was a bit too much work/alteration than I want to do for a mask I purchased.

    If it had a decent way to stay secure to the face I would rate it 4-5 stars, due to the ear loops I would give it 2.

    As a teacher in the UK, I needed something that was going to make sure I wasn’t going to be bringing the Covid virus home to a critically vulnerable member of my family. This masks fits the bill and gives me complete confidence to be around my students close up, while ensuring I can’t catch anything. The fit is fine – I use the head strap to ensure and extra super tight fit (feels like I’ve had a face lift by the end of the day it’s so tight!). There is no misting of glasses thanks to the soft foam nose band insert, so I am confident of no leaking in or out of the mask. I put the mask on at 8am in the morning and take it off very briefly to eat and drink, but put it straight back on as soon as I can and don’t take it off until I leave the school building around 4.30pm. Yes it can become slightly uncomfortable as the hours wear on, but I have got used to that and is a small price to pay to stay well and working and keeping my family member safe. If other teachers are reading this, then just to let you know that my students haven’t batted an eyelid at my wearing a mask, not have the parents. Yes you do sound a little muffled, but I have found with my big teacher voice, it hasn’t really been a problem! Great to not get any coughs or colds too and I have used 2 in rotation since September (now 1.1.21), so much better for the environment and both still showing no signs of wear and tear, other than a bit of the nose band. Thanks Cambridge for the confidence to keep going. My only suggestion would be to offer to sell the foam nose band replacements separately.

    The mask is wonderful. It’s a bit bigger than expected (I was in between sizes), so I have now ordered another one in a size S, but the M fits my husband really well, and it seems to be really comfortable. I like that the inner lining is black, as I always had problems with make-up stains on the inside with previous masks, which made me over-wash them. I think I will be wearing this mask a lot (FFP2s are mandatory in shops where I live), so it will be worth the money.
