    It works, but very finicky about how to fit in the machine

    The water container is the same as the original chamber that came with the machine. Has the same problem where you cannot fill it to the max due to notches on the hinge side. I have to push it carefully into the machine and wiggle it a bit to get a good seal. Otherwise air blows out around the chamber.

    Excellent product

    I recently purchased this product as a backup to my existing water chamber. It arrived quickly and in perfect condition. Sleep Doctor provides consistent, high quality service. Thanks!

    Awkward to fill but does the job

    The function of this humidifier container is great. It comfortably humidifies the air which greatly adds to my ease in using my CPAP. It is awkward to fill and easy to spill though. Still worth it!

    Easy and light to fill

    Pretty staight forward. Has a line to fill to with distilled water. close the lid and put it back in machine. looks easy to clean as well. I bought an extra one because I live in Mexico and I guess this needs to be replaced every so often - 6 mths I think it said
