6. Purified Water

When ground or tap water is heated to get rid of harmful substances like fungi, parasites, and bacteria, you get purified water. This makes it one of the safest waters for you to drink.

Pros

– Purified water is another great option if you aren’t sure of the condition of tap water in your area.
– Most countries put their tap water through a purification process, so the water that comes out of your kitchen sink is likely purified water already. This makes it easily accessible and cheap.

Cons

– While the boiling process rids of all harmful substances, it may also strip the water of some potentially beneficial ones that are added to tap water supplies, like fluoride, which reduces tooth decay.

– The cost of buying purified water, or even installing a home filtration system, can be more expensive than some people can afford.
