Yes, nearly 100% of it ! Not only that, our masks filters particles as little as PM0.3. If that isn’t enough, it also kills 99.77% of all bacteria and 99.6% of viruses! Please read more here.

Ah, our favourite question! Where do we start?

Firstly, we are the only pollution mask that uses military grade filtration technology! This guarantees the best protection against pollution particles as small as PM2.5 and PM0.3. Please have a look here for official testing results. Importantly, most other masks (we won’t name names) consists of granulated carbon, which is very thin and thus much less effective. Cambridge Mask™ uses activated carbon that is spun into a yarn and woven into cloth. The filter consists of a series of such activated filaments, with pores 25 times smaller than in other filter materials. This makes Cambridge Mask’s pollution masks the most effective pollution masks on the market!

Secondly, Cambridge Mask™ filters have been treated with silver, giving it anti-bacterial and anti-viral properties, killing and blocking 99.77% of all bacteria and 99.6% of all viruses!

Thirdly, what do you mean similar looking masks? Please have a look at our range of the most fashionable pollution masks on the market!

Cambridge Masks™ are non-disposable, meaning that you can use them for potentially hundreds of hours. The length of time they are suitable for depends on how polluted the environment is when you use it. A table is provided below, but a “rule of thumb” (a guideline) is that you can use the masks on a regular basis for upto 6 months before it needs replacing. Note that the masks are washable, but cleaning them only removes dirt not pollution trapped inside the filter. So the mask needs to be replaced after extended use to ensure proper filtration.

Air quality level	Air Quality index(AQI)	Description	Replace after
Good	Below 50	Clear visibility to horizon	Mask not needed
Moderate/Unhealthy for Sensitive Groups	51-150	Cannot see pollution with the naked eye, slight haze on horizon	340 hours
Unhealthy/Very Unhealthy	151-300	Haze at 2-3 km visibility	220 hours
Hazardous	301-500	Clouds of pollution, visibility around 1km	180 hours
Beyond Index	Over 500	Visibility below 600 meters. Fog-like clouds of pollution clearly visible even in bright sunlight	90 hours

Great question! The whole mask is the filter, this is why it lasts much longer than other pollution masks. Please see above for the exact time guidelines.

The valve is not the filter, it is there to reduce humidity for increased comfort in all weathers! In fact, it helps many people cycle to work in busy city centres around the world!

Yes, you can hand wash it with some soap. Since the masks last for an average of 200 hours, this is also recommended. And no, this won’t wash out the pollution or reduce the filtration capability. After all, our pollution masks are made from a military filtration material and can withstand more than a little water!
