I have now found that unscented Febreze works great. No smell. I use it on a cotton ball at the intake asap after taking it out of the SoClean. Then I allow fresh air to push thru it for awhile. No issues so far.
I found that putting a very small amount of Febreze on a cotton ball and holding it near the intake for a few seconds while on testing the mask fit mode.. gets rid of the ozone smell. Not too much or you'll have the Fabreeze smell too strong.
