Air quality drops at midnight every night in Nicosia area
My smart air filter has recorded a spike in air quality drop for the past 4 nights in a row around midnight. Tonight I had to close the window because it was getting into really high levels of PM1 and PM2 particles. Does anyone know what could cause this?
