>>480523for that many gallons you need to back flush,
>>480501 for taste you need a char coal filter since it taste is about the gases and minerals in the water. and those pass right through the sawyer mini. and any anti bio filter.
best solution for you would be a long term in line water filter like pic related. and the just have a specific drinking water tap.
unfortunately fluoride will pass trough almost any filter method in the world, so the tin foil filter has to stay
