    Wasn’t really sure where to put this. I’m having a not very fun issue. When trying to sleep, the air my sleeper is pumping out is so dry that it actually starts being painful to breathe in short order. If I manage to sleep, I wake up with painfully dry nose, sinuses and throat. This is with a seemingly useless humidifier running and keeping the AC pressure on low.

    Looking this up online, every mention of dry air seems to be related to running the heater in the winter... I’ve never had an issue like this before.

    Is there some kind of mechanical issue that would cause the AC to be near unbreathable dry air or is it just the result of Arizona and 100 degrees? I sleep during the day because of my schedule. Air quality is fine while driving

    While it's not really a dry air thing but more of a air quality thing have you changed your cabin air filters recently?

    A/C works by removing moisture from the air to no more than 16% humidity... Arizona probably doesn't have even that much moisture in the air to begin with... So dry hot air + A/C = really dry cool air.

    A/C takes any humidity out of the air. If there is hardly any air, it will remover a lot of it.

    As mentioned, start with the changing the filters.

    Also think about swamp cooler or mister to get some humidity up.

    An easy humidifier: wet a towel and hang it up somewhere in the cab.

    Any suggestions on a swamp cooler? Could they realistically cool a sleeper sitting in 100+ weather?

    Probably not cool it, but one would definitely add to you humidity level


    Edit: on 2nd thought. When i had to get a sleep apnea machine, it had a humidifier built into it. You have to add water to it every night. Maybe look into something like that.

    Crack the windows to keep some fresh air in might help some.
