Slidell water quality

The short answer

Slidell water is soft, chloramine-disinfected aquifer groundwater. The fix: a whole-home catalytic carbon filter plus reverse osmosis for drinking water.

Slidell water is soft aquifer water, disinfected with chloramine, and it runs on the higher side for sodium. Here is what that means for your coffee, your glasses, and the water you drink.

Chloramine, the disinfectant · the pool taste and smell in your coffee, your ice, and the first glass of the dayCatalytic carbon takes it out at every tap

Sodium, on the higher side · a mineral load you may be watching if you are on a low-sodium dietReverse osmosis at the kitchen sink lowers it for drinking and cooking

Dissolved minerals · white film on glasses and fixtures wherever the water driesReverse osmosis handles it at the kitchen sink

Here is what is actually in your Slidell water. It is soft aquifer water, and filtration still does real work at every tap.Ottie, your water guide.

Easier on the parts that wear out

Sediment settles in your water heater and lowers its efficiency, and chlorine and chloramine embrittle the rubber seals, gaskets, and hoses inside your appliances over time. Filtering the whole house is gentler on all of it.
