Most low-cost chemically synthetic air fresheners contain high levels of Volatile Organic Compounds (VOCs), with common harmful ingredients including benzene derivatives (e.g., toluene, xylene), formaldehyde, and acetaldehyde. These substances are typically added as solvents or preservatives, and their prolonged volatilization continuously pollutes indoor air.
Such products often include additional harmful components:
Phthalates (used as fragrance fixatives)
Artificial synthetic fragrances
Organic solvents (e.g., isopropanol)
Artificial antibacterial preservatives
These non-naturally occurring substances easily irritate the mucous membranes of the eyes, nose, and throat when volatilized. Contact with the respiratory tract or skin can cause discomfort, while long-term exposure to certain ingredients may potentially disrupt the human endocrine and metabolic systems.
Chemicals released by toxic air fresheners directly irritate the respiratory mucosa, frequently causing dry, itchy throats, coughing, nasal congestion, and sneezing. Sensitive individuals, children, and asthma patients may experience severe respiratory discomfort or airway spasms. Long-term exposure exacerbates chronic respiratory conditions.
Artificial fragrances, solvents, and other ingredients can trigger skin reactions such as itching, redness, and allergic dermatitis—especially when mist particles adhere to the skin in enclosed spaces.
Inhalation of certain volatile substances affects the nervous system, leading to dizziness, headaches, nausea, and decreased concentration. Prolonged exposure to high-concentration environments may also cause drowsiness, irritability, and other discomforts, impairing daily functioning and overall health.
The following low-quality products pose significant health and safety risks, often skipping compliance testing or using banned ingredients to cut costs:
Unbranded canned spray air fresheners: Lack formal ingredient labels, use industrial solvents and cheap synthetic fragrances, and contain excessive harmful volatile substances. Pressurized cans also carry leakage or explosion hazards.
Automatic fragrance dispenser refills: May include formaldehyde slow-release agents or industrial fixatives.
Bulk unlabeled fragrance oils: Unregulated, with unknown toxic components.
Cheap gel fragrances and solid fragrance chips: Often contain banned preservatives or high VOC levels.
Unbranded handmade fragrances/sachets: Use low-quality chemical aromatics or inferior fragrances.
These products are particularly dangerous when used long-term in enclosed spaces (e.g., bedrooms, cars), as they cause continuous harm to the human body.
To screen out toxic air fresheners efficiently, focus on the ingredient list with these key checks:
Benzene derivatives (formaldehyde, benzene, toluene, xylene)
High-VOC solvents (isopropanol, methanol)
Phthalates (fragrance fixatives)
Artificial synthetic fragrances
Preservatives like propylparaben
Products using vague terms such as "fragrance," "spice," "stabilizer," or "solvent" (without specific chemical names or safety codes) are almost always inferior.
Safe, high-quality air fresheners will clearly list:
Natural raw materials (e.g., plant essential oils, purified water, food-grade alcohol)
Specific ingredient names and content ranges
Implementation standards and quality inspection certifications
These details serve as core criteria for safe purchasing.
Select formal brand products with:
Clearly labeled natural ingredients (plant essential oils, purified water, etc.)
Attached quality inspection reports and implementation standards
No ambiguous ingredient descriptions or hidden components
Prefer solid or gel types over sprays (lower irritation for sensitive groups).
Avoid unbranded products, those with vague ingredient lists, or those explicitly containing artificial fragrances/VOCs.
Use moderately: Do not over-spray or use long-term in enclosed spaces; ensure ventilation after use.
Keep products away from children, pets, and food; avoid direct contact with the face or skin.
Sensitive individuals should perform a small-area patch test before regular use.
Replace products regularly to minimize cumulative health risks.
