I want to tell my story very briefly because I know that this information will be useful to someone. it so happened that my dad is sick and bedridden. Doctors have assigned him to use the CPAP Apparatus. But it turned out to be not an easy task for me because with daily use the device was very dirty and had to be washed several times a day. The way out was found by accident. I found mini cpap cleaner on homemakerguide.com. I advise you to purchase it immediately, it cleans perfectly
