    Never Run Out of Distilled Water Again

    Saves Time, Effort, and Money

    You won't need to carry heavy jugs of water home from the grocery store, and when packing for a trip, you can create travel-sized bottles of water on your own. In doing so, you'll be saving yourself valuable time, effort, and money.

    Using Distilled Water Helps Your Humidifier Chamber Last Longer

    By regularly using distilled water, you're helping extend the life of your humidifier water chamber. If you use tap water instead of distilled water, you'll be putting more strain on your machine and you'll wind up with a dirty humidifier chamber. You could also be voiding the warranty. By using distilled water, you're putting less stress on the machine and could be extending the life of your equipment.

    Make Your Humidifier Chamber Easy to Clean

    Using tap water as part of your therapy is usually not a good idea. When the water evaporates, it can leave behind hard calcified deposits which can be difficult to clean. If you use only distilled water for your therapy, there's no mess and no minerals to scrub away. Your humidifier chamber will last longer, and you'll have less cleaning to do.

    Not for Drinking: Removes Minerals, Fluoride, and Calcium

    Not to be confused with a pitcher that makes filtered drinking water! This pitcher is specifically designed to make distilled water for CPAP equipment that isn't intended for drinking. The H2O 4 CPAP distilled water machine removes a lot of the minerals, calcium, and fluoride from the water, making it safe for your humidifier and easy to clean.

    Uses Disposable Water Filter Cartridges

    The pitcher comes with the correct filter pre-installed, and replacement filters are available. As long as the filter is in good working order, you will be able to generate distilled water for your CPAP machine. Each cartridge will last 60 nights.

    Important Tips

    Not Intended for Drinking

    The intended purpose of this device is strictly for use as a part of CPAP therapy. While this product functions the same way as a filtered drinking water pitcher, it is not intended to serve that purpose. Fluoride, calcium, and other minerals help make tap water taste better and more appealing to drink; and this pitcher filters all of that out. Distilled water has a sterile and unpleasant taste, and while not harmful, you wouldn't want to use this product to create drinking water.

    Filter Cartridge Lifespan

    Filter cartridges come in packs of two and can last up to 60 days. When you purchase a 2-pack of filter cartridges, you'll get roughly a half-year supply of clean distilled water, that's free of toxins for quality therapy.

    How to Change the H2O 4 CPAP Filter

    Here's the steps you'll need to follow to change your H2O 4 CPAP filter. H2O 4 CPAP uses a special filter that's only compatible with the H2O 4 CPAP Distilled Water Pitchers, and will not work with any other make or model.

    1. Make sure the pitcher is empty before starting.
    2. Remove the top lid from the pitcher.
    3. Locate the filter at the bottom of the pitcher bowl. Grab the pull tab located on top of the filter, and pull up.
    4. Replace with a new cartridge and lock into place.
    5. Replace the top lid.
