If you do indeed have a efficient air filtration system which is really well sealed to the furnace the the source of the dust has to be the cooling coil the furnace or the supply air ducts.
Bmw white dust from air vents.
It would be odorless for awhile.
Looking clean we would put the filter back in and struggle through the diagnosis more.
No name bad a c cleaner.
Within this mist are dissolved minerals from the water itself.
Ultrasonic and impeller humidifiers produce humidity through a steaming process so when the water in the humidifier is heated the water turns to vapor which is then is sprayed out of the humidifier in a mist form.
Creating the white.
Spray inside the vents with a sanitizing enzymatic cleaner.
Does anyone know what this could be and maybe a solution.
However our techs would pull the furnace filter and they would be white as a pure snow.
The dealer had it back and put a cleaner through the system but had no effect.
Clear off and spray the air intake vents.
The minerals land on furniture tables counter tops etc.
Recently got a 118d m sport.
Typically a furnace will overheat if the air filter is plugged and the furnace can t pull enough air through it to cool the heat exchanger down.
There could possibly be some vapor or steam from water that has accumulated by way of condensation somewhere in the system and is sitting at the bottom of the vent and when the air flow hits it something that looks like steam is created carney says.
The air intakes are on the exterior of the car around the windshield cowling.
When the fan is turned on i get this white dust out of all the vents.
It is the same if the air con is turned on as well.
