How you purify household drining water?

I purify it by boiling as boiling is best method and then use filter and store water safely in one food grade make plastic gallon, then seal water containers tightly, label with date, and store in a cool, dark place. I do not use cloudy water which need filtered before boiling or adding bleach. I boil water at least 15 minutes. I never use only bleach or silicon filtered water or do not purify by only tablet or less safety mineral water as many disease create from drinking water. So with all device I first boil water for drinking.
