ReactFIT RF39 Face Mask

Place the mask to your face and  position comfortably between the nose bridge and chin. Secure the mask by the  velcro pads behind the head. Shape the nose clip so that it conforms to the  contours of the nose shape as this will ensure a good seal. When using a mask  with glasses, it is best to fit the mask first to get the correct fit with no  seal leakage, then place the glasses in front of the nose clip on the mask. A  good seal around the nose and cheekbone will mean no leakage in that region  which equals no misting to cloud the glasses. Our masks uses exhalation valves  that releases heat, water vapors and Co2. The removal of these components are  the key to comfort and elevated breathing rates. The filter material in the our  mask is subject to testing which gives 99% filtration of particulates smaller  than PM2.5 (2.5 microns) When not in use, the mask should be kept in a dry place  and any condensation should be allowed to evaporate. An important point with  respect to masks is how well they fit. It is important to ensure proper fitting  of the mask with the instructions above.

It is recommended that you wash the shell of the mask every month under  normal use. To do this it is necessary to remove the filter and the valve first.  Turn the valve caps to release the filter. Please be careful not to misplace any  of the components during maintenance. The valves should not need replacing on a  regular basis assuming that they are maintained properly. On a monthly basis, it  is advisable to flush the valves through with warm water, allow to dry and apply  a little talcum powder to prevent the valve from sticking. The malleable nose  clip deforms easily so that a good fit can be formed around the bridge of the  nose. Continuous or exaggerated deformation will eventually cause failure in the  metal – it will snap. Once a good fit has been found, it is best to maintain the  shape, rather than folding it flat when storing it or when not in use. The  effective working life of filters depends on a number of factors, such as; the  breathing rate of the user; ambient levels of pollution; the length of time the  filter is actively working; hygiene levels. Taking these factors into account we  recommend that the filter should be replaced every month or every 68 hours, or  when the filter becomes noticeably discoloured, whichever is sooner.
