Is Liverpool air pollution bad?
Liverpool experiences moderate to high air pollution levels, with unique challenges from port activities, shipping emissions, and traffic congestion. Average PM2.5 levels are 9-13 micrograms per cubic metre, exceeding WHO guidelines of 5. Major pollution sources include the M62, M57, A580 East Lancashire Road, Queensway Tunnel, and Liverpool Port. NO2 hotspots include the Strand, Lime Street, and Kingsway Tunnel approaches.
When is Liverpool air quality worst?
Liverpool air quality is worst during weekday rush hours (7-9am, 5-7pm) due to traffic congestion on the M62, M57, and tunnels. Winter months see increased pollution from heating emissions and westerly winds bringing maritime pollutants. Port activity and cruise ship emissions also contribute to higher pollution near the waterfront. Worst pollution zones include city centre, Kensington, Edge Lane, and areas near the M62/M57 junction.
How can I improve indoor air quality in Liverpool?
Use MERV13/16 air purifiers to remove 85-95% of PM2.5, NO2, and maritime pollutants indoors. Aim for 5-6 ACH in bedrooms and living spaces. DIY Corsi-Rosenthal Boxes cost £150-200 with parts from local Screwfix, Toolstation, or B&Q. Liverpool's coastal location means maritime pollution and salt spray can affect indoor air quality. Avoid opening windows during rush hours or when outdoor AQI exceeds 50.
