  • Anyone know what cause white sandy/powderly dust indoor?

    I have had the dust in my place for 2-3 months, but I didn't inform landlord until today. Sometimes, I feel it's very foggy in my room. I was told it is quite strange.

    Today, I used air purifier, and I was shocked to see within 1 hour, the blades were all covered with the white powderly dust.

    Anyone know what could cause this, and how do I deal with it?

    Thank you!!
