To lower TDS, you need an osmotic filter. Osmotic filtration is not practical for shower filters. The flow rate would be just a trickle. TDS mostly affects the taste of the water, but some inorganic minerals can be unhealthy if you are drinking the water. From a showering perspective, TDS does not matter.
