How It Works:

2. Pour tap water in the small compartment located near the pitcher handle. Be careful not to over-fill.

3. In seconds, you will have a full pitcher of clean, contaminant free, distilled water! 


Product Features:


Eliminate Calcium and Minerals


Remove Harmful Contaminants


Eliminate Calcium and Contaminants

Unlike conventional drinking water filter pitchers which do not remove calcium, our H2O 4 CPAP device is designed specifically to remove contaminants from tap water. This device produces ion distilled water -- without any calcium or other minerals to help prevent the hard water buildup that tap water tends to cause. Regular use keeps your CPAP humidifier good as new!

Remove Harmful Contaminants

Without the use of this effective water-filtering system, contaminants found in tap water can form dangerous, sandpaper-like scale within your CPAP humidifier water chamber. It will then become a breeding ground for bacteria pathogens. These pathogens, which thrive in warm, moist environments within CPAP water chambers, can harm the respiratory system.


Each H2O 4 CPAP filter cartridge will remove harmful toxins from tap water for up to 60 nights and makes 6 gallons of ion distilled water. This highly effective device costs just pennies per night to use. It also eliminates the inconvenience to buy gallons of distilled water.

Bad design with the filter system Alexander W., 07/25/2020

I have known for a while that I should be using distilled water in my CPAP machine, but frankly I've been to lazy to go to the store and buy the water. This filter solves the problem and costs less than bottled distilled water. Great Water Solution, 09/18/2019
