These are the replacement filters designed for use with the H2O 4 CPAP Distilled Water System. The H2O 4 CPAP conveniently turns tap water into distilled water almost instantly. Failure to using ion distilled water in your CPAP humidifier allows contaminants that are found in tap water to form dangerous, sandpaper-like scale within your CPAP humidifier water chamber.

Usage Information: Each filter can last for up to 60 nights and makes 6 gallons of ion distilled water, 1 gallon typically lasts for 10 nights.

    These were purchased as a gift from my sister to me as I was always complaining about lugging gallons of distilled water from the store to home! The ease of being able to use tap water to distill water is great. I highly recommend using these instead of those clunky gallons!!

    There’s no more running out of distilled water with H2O 4 CPAP. And is terrific at fulfilling order.
