3 Steps Everyone Can Take Today to Improve Indoor Air Quality

We often think of air pollution as an outdoor problem — smog-filled skies, busy highways, or factory emissions. But research shows that the air inside homes, offices, and schools can be two to five times more polluted than the air outside.

The good news is that there are simple, practical steps you can take today to improve your indoor air quality. While technology and monitoring provide deeper insights, these three actions can make a noticeable difference right away.

Step 1: Improve Ventilation

Fresh air circulation is one of the most effective ways to reduce indoor pollutants.

• Open windows regularly to let stale air out and fresh air in, especially when cooking or cleaning.

• Use exhaust fans in kitchens and bathrooms to remove smoke, steam, and odours.

• For offices, ensure HVAC systems are properly maintained and filters are changed frequently.

Better ventilation helps reduce concentrations of pollutants like nitrogen dioxide (NO₂), carbon monoxide, and volatile organic compounds (VOCs).

Step 2: Introduce Air-Purifying Plants

Nature can play a role in cleaner air. Some plants are known for their ability to absorb harmful chemicals and improve humidity indoors.

• Spider Plant: Removes formaldehyde and carbon monoxide.

• Snake Plant: Filters multiple pollutants and releases oxygen at night.

• Peace Lily: Absorbs VOCs and increases indoor humidity.

While plants are not a complete solution, they provide natural support alongside other measures.

Step 3: Monitor and Act on Air Quality Data

The most powerful way to take control of indoor air quality is through monitoring. Without data, pollutants remain invisible.

• Use air quality sensors to track levels of PM2.5, VOCs, humidity, and other pollutants.

• Take targeted actions when levels are high, such as increasing ventilation or using an air purifier.

• For businesses, share transparent data to ensure healthier workplaces and meet ESG standards.

At PurerAir, we believe that everyone should have access to accurate, transparent air quality information. By combining decentralised science (DeSci) and blockchain, we are building a future where air quality data is reliable, open, and owned by the community.

Cleaner Air, Healthier Living

Improving indoor air quality is not just about comfort — it’s about protecting long-term health. Small steps like better ventilation, adding plants, and monitoring your air can make a meaningful difference.

With the right tools and awareness, we can all breathe easier, whether at home, at work, or in our communities.
