A full 4 months of Serene refills in one box, matched to how the cartridges actually wear out.
The blue mineral cartridge lasts up to 4 months. The yellow bromine cartridge lasts about 1 month. The standard refill kit has 1 mineral + 3 bromine, so you run out of bromine a month before the mineral is done. This kit adds the 4th bromine cartridge so both run out together.
