CPAP DISTILLED WATER for sale ?

I’ve always given up on finding distilled de mineralized water for my c pap machine here in zihua.

Has anyone been able to buy it here and where ?

I’ve not the equipment nor desire to make it myself.

Even with using bottled water there is too much calcified residue left in water cartridge and then I end up breathing that in.

Thank you in advance.

I turn the heat way down on mine and run it dry.
