How does dust from the building site next door get in, and how can you reduce it?

What can you do?

1. Fit a filter to the window. Window filter lets air through and holds back fine dust. So you do not have to keep the windows shut while the building work goes on.
2. Do not forget the vents. The same filter can be cut and applied to vents and air inlets too.
3. Keep track of working hours. The dustiest work is usually done in the daytime; move your airing to the evening.
4. Damp cleaning. Pick up dust with a damp cloth before vacuuming.
