This is the price that attracted me, almost 30% less than the Brita cartridges. This applies not worth paying full price! These generic cartridges are quite functional. It fit perfectly without the need for adapter or other. Filtration is equally quick and efficient. No additional manipulation for Brita to start up a cartridge (immersion for 15 minutes and 2 filtrations "blank"). The taste is no different and the water is clear. I advise!
