Review on HydroGardener Replacement Filter for Home Master ISetTMA8 by Francisco Garcia

Bought replacement filters for a HomeMaster reverse osmosis system that I bought a year ago. It seems to be doing its job. I don't have all the water tester kits, just a TDS meter, and regular tap water at So Cal is around 500-600ppm, going through reverse osmosis filters got it down to around 40ppm for the first few weeks. After about 5 months, the TDS is around 30 ppm. So filters remove all minerals and the reverse osmosis system I got reintroduces minerals after filtration. I thought I should expect a slightly higher TDS ppm due to this process, but it seems to be an average I'm getting at work, which is around 26 ppm. I still have to do some research, but other than that it's a good filter. The water tastes like it was bottled and looks clear.
