Paragon Luxury Hand-Held Shower Filter Head
Shower Filter Review by Gerald Evans
37000 liters does not mean much to most people. Neither does one year. It would be useful to indicate with shower filter heads how many showers can be got depending on what level of hardness of water.
Then people can calculate life of filter based on there known average usage. Some people shower one or more times per day depending on work and weather and other factors. This would be useful
