Typically the most effective filtration systems are those that distill the water, or use reverse osmosis technology. There are some companies whose filters use alternate processes to successfully purify water, but it is vital to dig into their testing results to ensure that they are filtering to the degree they’re being marketed as. Brita, purity, and other top filtration companies do a very poor job of filtrating water. It is not recommended to rely on them for safe drinking water.
Spring water is an alternative solution to drinking water that is incredibly supportive to the body. If you can access a spring close to you that is not saturated in pesticides, chemicals, or feces from animals then that is an excellent option. Testing this water if you are unsure is a good idea (there are testing kits that can be ordered online).

It is essential to reintroduce minerals to water that has been distilled or gone through reverse osmosis. This water is stripped of minerals that are critical to the body. High quality salt is an excellent source of minerals and can be added to water. Herbs are another great way to add in minerals as well as naturally structure your water.
