Traditionally, people turn to candles in order to enjoy a delicious scent in their homes, but what about those that can't burn candles? An electric fragrance device might be the answer for those who, due to breathing problems such as asthma, might not be able to enjoy a scented candle. For those with asthma, anything that puts even small amounts of impurities in the air might trigger an attack. Since some candles do put small amounts of soot and other elements into the air, a cleaner, electric fragrance device could be an excellent alternative to scenting a home without worrying about causing those with asthma to suffer. Strong scents can sometimes irritate the respiratory tract of those who have severe allergies. Since some electric fragrance devices allow you to control how much scent is released a setting on low may allow for a light fragrance in the air without overpowering those who have scent related allergies.
