Air pollution is a major problem throughout the UK and beyond, causing harm, and even death, to thousands of people each year. But, Clean Air Day, which this year takes place on 21 June, aims to raise awareness of the problem as well as encouraging people to take simple steps to reduce the pollution they create.

Dan Bourke looks at the recent findings of the All-Party Parliamentary Group (APPG) for Healthy Homes which focused on the impact on our nation’s health and economy as a result of people living and working in unhealthy buildings.

By their nature, bathrooms create much steam and water vapour. Without proper ventilation, this can turn to condensation and damp, not just in the bathroom, but also in nearby rooms.

There are several types of condensation: surface condensation, cold-bridge condensation, warm-front condensation, interstitial condensation, reverse condensation, radiation condensation.

All homes need to have adequate ventilation - it can help to prevent damp and mould caused by condensation, and can reduce the chances of contracting health issues caused or exacerbated by poor indoor air quality.

The annual event, Clean Air Day, takes place on 21 June. Organisers are urging people to leave their cars at home for the day after pollution-busting data gathered on the day of the London Marathon showed a huge drop in air pollutants during the largely traffic-free day.

Property maintenance can be one of the most daunting aspects of renting out a home. Handily, with the right checklist, everything becomes a lot easier to manage.

Believe it or not, there are up to 900 chemicals in indoor air. Not only this, but according to the Environmental Protection Agency, indoor air is found to be up to 70 times more polluted than outdoor air.

Bryony Perry, Specialist Ventilation Expert at the UK's leading ventilation manufacturer, EnviroVent, gives her advice on preventing mould and condensation issues in landlords’ properties.
