Maybe I should clarify my question.
I was curious as to whether filtered water is used for all household uses. Such as washing the car?
Ya. Somehow I feel that the sediments in the water will scratch the car surface paint. Also will affect the clothes. When I use it to wash the interior floor I don't feel clean at all. Feels a little sticky and became dusty faster. Just my personal view. Better to be on the safe side.
Or is it limited to only water coming into human contact e.g. brushing teeth, bathing, & showering? Or is it only for cooking & washing dishes:confused
Just for cooking and drinking, as well as for washing of vegetables and food, I had another with 6 filter fixed onto the kitchen tap. That one is a bonus for a health purposes.
