1. Health problems
Allergic reactions: The essential oils or other aroma ingredients used in the diffuser may contain certain allergens, and for people with allergies, exposure to these allergens may trigger allergic reactions, such as itching, redness, swelling, difficulty breathing, etc.
Respiratory discomfort: Inhaling the aroma emitted by the diffuser for a long time may cause irritation to the respiratory tract, causing respiratory discomfort symptoms such as cough, sore throat, and chest tightness. This irritation may be more pronounced especially for children, the elderly, or people with respiratory conditions.
Second, air quality problems
Harmful gas release: Some aroma diffusers may release harmful gases, such as formaldehyde, benzene, etc., which may have a negative impact on indoor air quality, and long-term inhalation may cause harm to human health.
Chemical residues: Some aroma diffusers may use essential oils or aroma ingredients that contain chemicals, such as flavors, preservatives, etc., which may remain in the air or on the surface of indoor items, causing potential harm to human health and the environment.
3. Fire risk
Electrical faults: Aroma diffusers usually need to be plugged into a power source to operate, and if the electrical wiring is faulty or aging, it can cause a fire. In addition, the use of substandard power cords or plugs may also increase the risk of fire.
Open flame hazard: Some diffusers use an open flame such as a candle as a heat source, which can cause a fire if used improperly or left unattended. In particular, the risk of fire is higher when using an open-flame aroma diffuser near flammable items.
Fourth, economic costs
Essential oil consumption: Aroma diffusers need to change essential oils or other aroma ingredients regularly, which can increase financial costs. Especially for some high-end aroma diffusers, the essential oils used** are expensive, and long-term use may bring a large financial burden.
Machine maintenance: Aroma diffusers need to be cleaned and maintained regularly to ensure their proper operation and longevity. These maintenance tasks can take time and money.
