Obviously it's not really that relevant if were talking about making the water safe to drink in the first place because boiling is much more effective. And again the claim that medieval people drank beer all the time because all the water they had access to is dirty is a myth.. Ensuring access to clean water was something medieval people took very seriously with very severe punishments for those who polluted or tried poisoning sources of drinkable water.
