CADR: why it’s not a reliable standard for choosing an air purifier

In recent days, several figures have brought attention back to an increasingly critical issue: air quality in Italy. According to Il Fatto Quotidiano, the numbers for the first quarter of 2026 show a significant worsening, with pollutant levels still too high in many areas of the country.

The data: particulate, NO2 and ozone still above the limits

The analyses show that the main pollutants (in particular PM2.5, nitrogen dioxide (NO2) and ozone) continue to frequently exceed the recommended limits. These are substances associated with respiratory and cardiovascular problems and with an increased risk for the most vulnerable groups of the population.

The picture is clear: despite regulations and controls, air pollution remains a structural problem, especially in urban areas and in the Po Valley. To learn more about the role of traffic, read our article on urban air pollution and traffic.

Why this also concerns the air you breathe at home

An often underestimated aspect is that outdoor air directly affects indoor air. Fine particles and polluting gases enter the home through windows, doors and ventilation systems.

The solution: controlling indoor air

If it is not possible to act on outdoor air quality, it is possible to act on the environment where you live every day. High-quality air purifiers, with medical-grade HEPA filters and activated carbon, are designed to remove:

• Fine particles (PM2.5 and PM10)
• Allergens and pollen
• Odours and chemical compounds (VOCs)
• Bacteria and ultrafine particles

Professional solutions such as Austin Air purifiers use advanced filtration systems designed for continuous use in homes and workplaces. To find your way among the models, see our complete guide to air purifiers.
