From a a technical standpoint the filter material is the same, an electro statically charged non-woven material that is tested for the removal of 99% of all sub micron particulates down to 0.5 microns. The mask has to seal to allow inhaled air to pass though that filter. If the mask does not seal properly, then no matter how good the filter is, air will pass around the sides of the mask unfiltered.
The white Respro® StreetSmart™ Mask, is certified to European Standard (EN149-FFP3). The black Respro® Streetsmart™ Mask is currently undergoing certification. It has been manufactured within the technical specification of EN149-FFP3NR. Both masks offer the highest level of protection for the removal of PM2.5. The FFP3 is equivalent to the American Standard N99, which is higher than N95.
A regular commuter will find this mask invaluable for their daily trips in the city as it can be re-used in these environments*.
The Respro®StreetSmart™ Mask has been specifically designed with a unique seal to ensure an excellent fit for a variety of face shapes. This inner face seal helps maintain a close, snug fit around the nose and chin areas which is regarded to be the main weakness on most standard face masks. There are two head straps: one that sits at the top of the head and a second adjustable strap that clips around the back of the neck.
One size fits, large, medium and small faces and is glasses compatible.
From the practical point of view, we would not recommend the Respro® StreetSmart™ for running or any other activity that requires an elevated breathing rate. It would soon be obvious that anything above walking or home use would not be suitable and that the mask would become restrictive over a period of time.
The price reflects the aesthetic point of view, the Respro® StreetSmart™ is somewhat less attractive and in todays visual world, masks have to be seen to be cool as well as function efficiently.
The durability or reusability of the Respro® StreetSmart™ is not the same as a Respro® sports mask, whilst it can be used several occasions it is ultimately a disposable product unlike Respro® sports masks which have a replaceable filter and a durable shell that have comfort and aesthetic built into the design.
The benefits of the Respro® StreetSmart™ mask are there to ensure that the end user can acquire the best ‘industry standard’ product, albeit with regards to one particular pollutant type that of PM* or Particulate Matter which is currently being commented on around the globe as the major pollution concern.
* if used under guidelines for Health and Safety in the work place, this mask is regarded as a ‘single shift’ respirator. The black Streetsmart™ Mask, undergoing certification, is currently not suitable for use under these guidelines.
