White Dust throughout the house
Over the past 4 weeks there has been an abundance of thick white powdery dust that has accumulated throughout the house. More so in the master bedroom. Any thoughts on this. I have added a air purifier (high end to correct this issue) and it does nothing but clog up the purifier. Any thoughts on this. I don't run the air conditioner often yet as the temps here in Las Vegas have not hit uncomfortable proportion yet but I don't imagine it will be much longer.

Atomizing humidifiers with hard water have this effect. Regards TB

Last time I saw this, a UV light was eating the media air cleaner.

Possibly a leaking dryer vent. Could be fine lint. I find this more times than not.

The high end purifier may be removing the contaminants in the air that make dust a dark color and now the staining agents are being removed and now the dust is appearing white. Just a thought.

If its a new house or you have done recent remodeling (drywall, inside french drains, etc.) then the dust is likely from those projects.
If not, 4 weeks ago did you or someone else in your home remove and inadvertantly reinstall a dirty filter backwards?

do you have a whole house humidifier? if so the evaporating water leaves behind minerals( which is a white powdery substance) that will go throughout the house. routine maintaince and a flush cycle can easily get rid of that.
