Does Purified or Filtered Water Work as a Substitute for Distilled Water? Purified or filtered water can contain minerals that may lead to buildup in your CPAP machine, so it's best to use distilled water. The distilling process eliminates minerals, chemicals, and bacteria, leaving the purest possible water behind.

Refresh Pure Water is a Western Australian owned and operated company that has now expanded across the country. Refresh Pure Water is Australia's largest producer of distilled drinking water with a capacity to produce more than 10,000 litres of distilled water per hour.

First, rinse only with distilled, sterile or previously boiled water. Tap water isn't safe for use as a nasal rinse because it's not adequately filtered or treated.

This process removes impurities and minerals from the water. Some sources claim that drinking distilled water will help detoxify your body and improve your health. Others claim distilled water leaches minerals from your body and could put your health at risk. In reality, neither of these claims is entirely true.
