Hi Elizabeth @ess77, I usually wash my CPAP hose once a month and rely on the SoClean 3 machine to sanitize it daily. I stopped using a humidifier tank and it works better for me without it.

Here's what the SoClean recommends -- "Can I stop washing my CPAP equipment if I am using the SoClean? Your CPAP equipment is completely sanitised every time you use the SoClean. However, the SoClean will not remove facial oils or dust or other foreign materials. You should hand wash your CPAP equipment with the pre-wash solutions every 5-6 weeks." --- SoClean CPAP Cleaner & Sanitizer FAQs: https://www.soclean.com/uk/soclean-faq

I'm glad to hear the CPAP is working well for you.
