Aera’s advanced technology creates a safe to breath, discernible scent effect with very small amount of fragrance ingredients in the air. This means in every million molecules of air, fewer than 10 are fragrance molecules. Individual scent ingredients usually amount to no more than 1 molecule in every million (< 1PPM) so low that the Aera scent effect can be responsibly called ‘hypoallergenic.” All fragrance ingredients are approved by the IFRA (International Fragrance Association) for safe use in air fresheners. The Aera scent effect also complies with the safe maximum airborne concentrations of Occupational Health and Safety Administrations (OSHA). The OSHA maximum standard assumes continuous inhalation for 8 hours a day, 5 days a week for a natural lifetime.
Concerns have been raised that essential oils (also known as naturals) may be harmful to pets. While there is no scientific evidence to support this, as Pet owners we take the assertion seriously. In fact, Aera fragrances and the scent effect created by the Aera diffuser are not harmful to pets. We assert this for 2 main reasons. First, an essential oil is a compound of chemicals derived by natural means. In the essential oils we use, each ingredient is either not restricted by OSHA (Occupational Safety and Health Administration) or if there is a OSHA maximum quantity that can be safely in the air, this maximum is strictly observed. Second, even if pets have a unique susceptibility to one or more ingredients in an essential oil, used as directed, the total essential oil compound (all the ingredients together), in the air is less than 1 air molecule in every million air molecule (<1PPM) the actual amount of any particular ingredient is less. These are so-called “trace” quantities meaning so tiny they cannot be measured by conventional means.
Humans and pets should not put their nose within 12 inches (30cm) of the scent outlet on the Aera capsule when the device is running. Within 12 inches the concentration of fragrance ingredients is much higher than referenced above and may cause unpleasant irritation to a degree which will discourage doing it twice. Here are rules which will avoid higher concentrations.
A simple precaution is to avoid the irritation which may be caused by unusually high concentrations of scent is to not position the diffuser adjacent to a bird cage or other confined spaces where pets or small children hang out, sleep, or play for long periods of time.
The inhalation of very high concentrations of fragrance may cause irritation including watery eyes, headache, cough, and upper respiratory discomfort. What does “very high” mean. Very high is when the concentration of scent is intolerable by the human olfactory.
