cover up your head immediately, the moment when you get up in the morning, avoid ceiling fan, dont go immediately outside for sometime...all this will help from sneezing and running nose
Change filter regularly. Also in addition to cleaning pillow, etc, run a one part ginger three part water solution to clean internals on the machine out of your reach. A drop of grapefruit seed extract stirred in your nightly Cpap water will also help w sneeze
Hello and hope you are doing well.
If you're new to CPAP machine the constant blowing could cause episodes of sneezing. Start with lower pressures. Also, have the filters cleaned out. Further a moisturizer may help. If any nasal blocks try to keep them patent with OTC nasal decongestants.
Hope this helped and do keep us posted.
