Household cleaning products release harmful nanoparticles

A study from Purdue University indicates that scented cleaning products can release billions of harmful nanoparticles into indoor air within minutes. These ultrafine particles, ranging from 1 to 30 nanometers, are formed when terpenes found in scents like citrus, pine, thyme, or lavender react with indoor ozone.

Research suggests that the dose of particles inhaled during cleaning can be comparable to levels associated with road traffic emissions. These particles can penetrate deep into the lungs, potentially causing irritation, inflammation, and respiratory issues. They may also aggravate asthma and increase cardiovascular risks.

Experts recommend using products that are minimally or not at all scented and emphasize the importance of thorough ventilation during and after cleaning to maintain indoor air quality. Even natural alternatives, such as essential oils or burning sage, are not entirely free of risks.
