I̢���ve used CPAP for about 25 years and every year like clockwork I̢���d get diagnosed with upper respiratory infection, sometimes twice a year. I would rinse out my CPAP humidifier every morning and wash my nose pillow. The hose, about three or four times a year! My thought was that the hose was dry and probably didn̢���t trap anything that could harm me. Besides I would typically replace the hose once a year and finally; how the heck would I wash it anyway, vinegar solution? Yuk!
I got tired of getting sick with URI so I bought the cleaning machine that I heard advertised on the radio. It uses an ion generator or something like that. Damn, it stunk after using it so I returned it and bought this brush kit. Using clear liquid detergent from the grocery store I began washing alternate sets of hoses on a weekly basis in my bathroom lavatory. It̢���s been 2 years since I̢���ve had a URI! Call me ignorant but WOW what a difference.
I alternate hoses weekly, hanging the one I washed in my closet over the clothes rod, same with this brush. CPAP has been great for me and now with a little discipline washing my hose, head gear and humidifier reservoir I̢���m free of URI! Try it!
