Are Scented Cleaners Creating Indoor Air Pollution?

THURSDAY, Aug. 27, 2026 (HealthDay News) — The citrus, pine or floral scent of a freshly cleaned room may come with something unexpected: invisible air pollution.

A new study warns fragrances in both conventional and botanical cleaning products can react with ozone in indoor air, forming nanoparticles that can travel deep into the lungs if inhaled.

In a model home, researchers found that mopping floors, spraying counters and wiping surfaces with scented products generated billions or even trillions of these ultrafine particles.

They say the respiratory dose can be comparable to — or even greater than — standing outside along a busy road.
