Can a Home Ever Be Dust-Free?

Dust doesn’t announce itself. It quietly settles—no matter how carefully we clean, close doors, or plan ventilation.

We have a lot of dust here in India. I did not watch, but there was a video on why there is so much dust in India. So it looks like this is not an India-specific issue, but rather common across much of Asia.

This means there is no point in me complaining about dust in my room. Despite cleaning thoroughly and keeping my door shut at all times, the room does get dusty on floors every two or three days. Since I don’t actually use this room all day, and since the door is closed, I don’t see the need to sweep the floor or mop every day.

I have mosquito nets on the two windows, each facing east and south. Even during monsoon, when there is no strong wind, I see dust accumulation. This means dust is obviously fine and light-weight material which remains in the air and settles on the floor and furniture. This happens even with the slight movement of air in non-wind seasons.

So if I want to keep my room dust-free—and preferably the whole home dust-free—what are my likely practical options?

Keeping all windows and doors closed is an impractical one and is prone to other detrimental effects on health and overall well-being.

Having completely transparent glasses for windows and removing mosquito nets is one option. This way I can have a lot of sunlight into my home, to be reduced as necessary by some dark curtains. The little air circulation needed at home can be achieved by keeping a couple of doors open with mosquito nets all day. There is a one-time cost and easy maintenance, I suppose.

But what about air curtains?

I wonder how expensive they are. Would I need multiple units? Are they really effective?
