AQI and noise: the invisible things that decide if you stay

You will not fall for a flat because of its air. You might leave one because of it.

Air and noise never make it onto a listing, and they quietly decide whether you renew or move. You do not notice them on a quick daytime viewing with the windows shut. You notice them three weeks in, at 1 am, with the windows open because it is summer.

Both are intensely local. "The area is fine" can be true for the area and false for the one flat facing the main road, two floors up, exactly at horn height. These are window-by-window facts, and they deserve window-by-window checking.

How to check in one visit

  • Go at rush hour, open the windows, and stand on the balcony for ten minutes. Just listen.
  • Check which way the flat faces. Main-road and junction-facing units carry the noise and the worst of the dust.
  • Mind the floor: higher is usually quieter, but level-with-the-flyover is the loudest place in the building.
  • Look around for construction sites. Each one is a year or more of dust and drilling on your horizon.

These are not small things. They are the difference between a flat you tolerate and a home you keep, and they are almost always knowable in advance. One honest visit at the right hour, plus one question to the people already living there, covers most of it.

Check the invisible things first. They are the ones you cannot repaint.
