ScentAir is considered safe for general use in 2026, as their products meet or exceed the rigorous safety standards set by the International Fragrance Association (IFRA) and the Research Institute for Fragrance Materials (RIFM). Their fragrance oils are formulated without phthalates, respiratory allergens, or known carcinogens. ScentAir systems use "dry-air" diffusion technology, which releases fragrance as a microscopic vapor rather than an aerosol spray, meaning no liquid droplets fall on surfaces or into the lungs. In 2026, they are fully compliant with EU REACH and California’s Prop 65 regulations. While the concentrations used in hotels and homes are far below the scientific threshold for toxicity, individuals with severe asthma, COPD, or Multiple Chemical Sensitivity (MCS) should always exercise caution and consult their physician. For the average person, the levels of Volatile Organic Compounds (VOCs) emitted by these systems are significantly lower than those found in many common household cleaning products or standard scented candles.
