Improving air quality usually starts with ventilation — getting more fresh air in and removing stale or polluted air. Local exhaust systems, such as extraction hoods, can remove contaminants right where they’re created. Using safer materials, improving housekeeping, controlling humidity, and maintaining HVAC systems all help too.
Sometimes small things make a big difference: stopping the use of strong cleaning chemicals, preventing indoor vehicle use, or ensuring filters are changed regularly. The key is to reduce pollution at the source wherever possible.
