amazing product, have gone thru several over the years
amazing product, have gone thru several over the years. a tip to extend their lives... dont put the storage caps on until any moisture you have breathed into it has evaporated. also every week or two gently tap it against a counted top or something solid to agitate the active carbon. this helps prevent gunk building up and blocking off air flow.
