Is it safe to use filtered water from a brita filter to make babies formula? i would boil it aswell

Why either ?: If you have an approved city water supply & drink from the tap there is no reason to do anything special with formula. Boiling would be an issue if you are on private well water & are unsure of the contaminant level. Filtering would also be a good idea. Six decades ago boiling was a common practice with moms who made their own formula from cow milk, but it was done to make it digestible.
