I use this myself at my house, when traveling, and I love it because of how portable it is. This shower filter helps filter out heavy metals, fluoride, chlorine, and a lot more toxics you don’t want going into your skin pores. Material that is used for this shower filter includes ABS and it is finished by 100% chrome. This shower filter is extremely easy to install, and there is two cartridges included which will last you 4-6 months. The filter is good to replace every six months, and it does not mess with the water pressure of your shower.
