Companies across the globe are including fragrances in their heating and ventilation systems. It's part of what emotional branding companies such as DMX call a multi-sensory experience. Retail stores may use scent in combination with audio and visual systems to enhance brand awareness. Smell associations, say DMX, are so strong they can even increase worker productivity. Whatever the reason, these scent systems can make it difficult for employees working in the affected areas who have fragrance sensitivities.
While it won't be possible for all workers in controlled scent environments to wear respirators, for those who can, we have a few suggestions. 3M 7500 series respirator masks are made from soft silicone that is very comfortable and hypoallergenic. This can be paired with the 3M 2097 Particulate Filter P100 that will filter out the scents created by these systems.
If a smaller, disposable mask is preferred, the Moldex 2400 N95 Nuisance Mask for Organic Vapor also works very well. It has a thin layer of charcoal to remove vapors and smells as long as they don't reach high levels. The Moldex 2400 is made of Dura-Mesh which helps keep the mask clean. This is handy because with light use, the Moldex 2400 N95 mask can be used several times before being thrown away.
