if the cartridges you need, you are at right place, delivered quickly and well packaged. However, I realized that these cartridges, in addition to dow absolutely no green because you can not recycle and brita does not recover or you have to make for their terminals, are only effective to remove the taste of water and prevent furring your kettle as limestone is filtered. no effect on bacteria even worse if the filter is not permanently submerged, mold can appear and crap are released in your water ... the water can only be preserved 48h grand max, so basically I serves me to water my plants, I filled the carafe and make tea and coffee with just filtered water. short, I do not Rasht!
