The regular ol’ dust that collects on surfaces- what is it? I imagine it consists of particles of a lot of different things, but is there any single predominant source?

> Most indoor dusts are composed of relatively common environmental materials including organic and mineral fibers, mineral grains, metal oxides, and biological particulate. These dusts typically have a mixed source, including particulate derived from building materials, textiles, paper dusts, soils, and biological sources. The complete characterization of indoor dusts usually involves a two level analysis. Most of these materials are easily identifiable by polarized light microscopy (PLM) and often this alone is sufficient. Occasionally, additional analysis by scanning electron microscopy (SEM) or, in the case of asbestos, transmission electron microscopy (TEM) may be necessary.

A larger factor in newer homes is carpet fiber, I would surmise.

When you vacuum/hoover the carpeting, some fibers are ejected into the air and land on furniture. The intake vents on your home’s HVAC system distributes this ejecta rather well, filter or no.

This quiet dust was Gentlemen and Ladies,  
And Lads and Girls:  
Was laughter and ability and sighing,  
And frocks and curls.  
–Emily Dickinson

But O this dust that I shal drive away  
Is flowers and kings,  
Is Solomon’s temple, poets, Nineveh…  
–Viola Meynell

And when the mayor comes to get my vote tell him  
When are you going to stop people killing whales!  
And when the milkman comes leave him a note in the bottle  
Penguin dust, bring me penguin dust, I want penguin dust-

- Gregory Corso

The lamp hummed:  
“Regard the moon,  
La lune ne garde aucune rancune,  
She winks a feeble eye,  
She smiles into corners.  
She smooths the hair of the grass.  
The moon has lost her memory.  
A washed-out smallpox cracks her face,  
Her hand twists a paper rose,  
That smells of dust and old Cologne,  
She is alone With all the old nocturnal smells  
That cross and cross across her brain.  
The reminiscence comes  
Of sunless dry geraniums  
And dust in crevices,  
Smells of chestnuts in the streets  
And female smells in shuttered rooms  
And cigarettes in corridors  
And cocktail smells in bars.”

- TS Eliot
