The filter is replaceable and is designed to remain effective until a noticeable discolouration of the filter occurs. The two Powa valves allow unimpeded exhalation, which is particularly important as they release heat, water vapour and Carbon Dioxide. Sportsta Protection: This mask is subject to testing which has been proven it to give 99% filtration of particulates smaller than PM2.5 (2.5 microns) and in fact, has been shown to be effective to filter microns up to ten times smaller; 0.3 microns. An important aspect of the effectiveness of mask filtration is how well they fit. If the mask doesn't fit well and air can pass through the gap where it fits, then it won't be effective; hence why multiple sizes are available. To find out what size you are, please visit our size chart.
These Respro Sportsta Mask Filters have a hypo-allergenic layer preventing any irritation to the face as a result of the accumulation of particulate material and have a wicking effect to ensure that the surface remains dry. The Respro Sportsta Filters also have an extremely low inhalation resistance compared with other particle filters.
The filter is replaceable, and is designed to be effective for at least 1 month in normal daily use. The two Techno valves allow easier exhalation, which is particularly important as they release heat, water vapour and Carbon Dioxide.
The sports filter has sub-micron filtration capability. What this means is that it is able to trap particles less than one micron in size which is more than capable of the removal of 2.5 micron particulate material (PM). Typically particulate pollution in the cities appears to be in the 2.5 micron size range. Particles smaller than this are known as respirable dusts, which can lodge deep within the lungs. This is the more dangerous type of particle pollution as chemicals from vehicle exhaust gases combustion known to be toxic, are carried by means of the respirable particles. Hence the need for a Hepa-type™ submicron particle filter. The Cinqro™ filter pack contains TWO replacement sports filters for use in Respro masks.
Dynamic A.C.C™ is laminated on both sides with a particulate material to prevent irritant dusts from entering the respiratory system.
The Respro Techno filter is suitable for use in heavily polluted environments, ie, air that is full of diesel particulates and respirable dusts that lodge deep within the lungs and air sacs. It is a combination of the Sports filter and the City filter giving you both sub-micron particle filtration with gas and vapour filtration. What this means is that the filter is able to trap particles less than one micron in size.
