VOC (Formaldehyde) Removal Service
What is Formaldehyde (VOC) and Why is it Dangerous?
Where Does Formaldehyde Come From?
Pressed wood products: Plywood, particleboard, and medium-density fiberboard (MDF) used in furniture.
Flooring & finishes: Wood floor laminates, adhesives, and varnishes.
Wall treatments: Certain paints, wallpapers, and glues.
Textiles: Permanent-press fabrics, carpets, and curtains.
According to the "Guidelines for Air Quality" published by World Health Organization in 2000, only when the level of Formaldehyde is lower than 0.024ppm, the condition is safe for us.
Why is Formaldehyde Dangerous to Your Health?
Short-term symptoms: Eye, nose, and throat irritation, coughing, and skin inflammation.
Severe respiratory issues: Chronic bronchitis, pulmonary edema, and internal ulceration.
Cancer risks: The US National Toxicology Program (NTP) officially classifies formaldehyde as a "known to be a human carcinogen."
What is a Safe Formaldehyde Level?
We are fully committed to protecting your health. We guarantee to reduce the formaldehyde levels in your property to a safe standard (below 0.06 mg/m³). If we fail to achieve this safe level after our treatment, you don't pay a single cent.
If the level of formaldehyde cannot be below 0.06mg/m3 in which level Formaldehyde is not harmful for human, we would not receive any payment!

Advanced Space Fumigation Treatment：
Our specialized Fumigation Treatment is a core component of Wong’s Formaldehyde Removal Service. Utilizing professional ultra-low volume (ULV) misting equipment, we disperse fine air-purifying particles that blanket the entire room. This specialized process allows the treatment to suspend in the air and penetrate hard-to-reach areas, ensuring full-coverage purification for the entire indoor environment.
Wong’s Professional Formaldehyde Removal: Fumigation & BioNatro® A1 Technology
Traditional photocatalyst products (such as Titanium Dioxide, TiO₂) heavily rely on strong sunlight or specific UV light wavelengths to trigger their purification process. Consequently, in pitch-black or low-light areas—such as the deep back of cabinets, walk-in closets, ceiling voids, and shaded corners—traditional photocatalysts become completely ineffective.
The exceptional performance of BioNatro® A1 is backed by rigorous testing from independent, third-party national laboratories, ensuring unparalleled scientific credibility:
2. Powerful TVOC & Odor Purification (GDCM): Beyond formaldehyde, it actively breaks down Total Volatile Organic Compounds (TVOC) released by paints and construction adhesives at a 90% efficiency rate, rapidly eliminating pungent new-home odors.
3. Industry-Leading Durability & Abrasion Resistance (XKS Testing): Passed a rigorous nano-curing coating friction test, successfully enduring over 10,000 rubs. This proves the solution adheres permanently to furniture surfaces for multi-year protection.
4. 100% Human & Pet-Friendly Safety Profile (GDCM Acute Oral Toxicity Test): Certified non-toxic through official acute oral toxicity testing and fully backed by a standard Material Safety Data Sheet (MSDS). It is entirely safe for babies, pregnant women, the elderly, and pets, leaving zero secondary chemical pollution.
