A breath of FRESH AIR

Many of us are concerned about the air quality on the streets of our cities and towns, but it's the pollution inside our four walls that could actually have the biggest impact on our health. Air quality tests have found that air pollution levels are at least three-and-a-half times worse inside than outside*.

Indoor air may contain up to 900 potentially dangerous chemicals, particles and biological materials, which can cause various health issues. And because we spend around 90% of our lives inside** – more during colder weather – we are often exposed to it. But there's lots you can do to make your home healthier this autumn - simply follow our expert tips.

A toxic mix

Never thought about indoor pollution? You're not alone. According to a YouGov survey, 72% of UK residents know nothing about the potential hazards and 55% aren't concerned about the issue.

But we should be. According to a study by Clean Air Day, our homes can become 'toxic pollution boxes', combining outdoor and indoor air pollution. It can cause coughing, fatigue and headaches, but it's also known to lead to more serious long-term effects, including allergic and asthmatic symptoms, cardiovascular disease, COPD (chronic obstructive pulmonary disease), respiratory infections and lung cancer.
