These carbon filters are heat sealed in aluminium foil for an extended shelf life of 10 years.
Extended shelf life is due to the aluminium barrier foil which has a water vapour diffusion rate that is 80 times slower than standard packaged polyethylene. The aluminium sealed package acts as a barrier to prevent water vapour from entering the pack and it performs the same protection in reverse as it retains the glycerine within the hollow fibre membranes.
The activated carbon filter is designed to screw into the underside of snap fit lid of both the LifeSaver 4000UF and 6000UF Bottles. Microbiologically clean water which has been passed through LifeSaver’s ultra filtration cartridge then gets filtered through the activated carbon filter for chlorine, taste and odour removal.
This pack of 4 activated carbon filters will filter 1,000 litres of water before a replacement pack is required.
