In recent years, eczema and asthma cases among children in Hong Kong have increased by up to 55%*, with newly renovated homes being the most affected!
You spend millions buying a flat and hundreds of thousands on renovation, yet you might be losing the most to the “invisible air risk”!
There are over a hundred chemicals in a new home, but the biggest culprit is formaldehyde: originating from glue, wood panels, and paint, with a release period lasting 3 to 15 years. 97% of families think “no smell = no problem” or “just ventilate for half a year,” resulting in:
Underestimating the risk: Formaldehyde is colorless and odorless; relying on smell alone cannot detect TVOC accumulation, causing babies to cough, elderly to feel dizzy, and even increasing leukemia risk.
Wasting effort: Randomly buying spray products from Taobao not only doesn’t work but may seal in pollutants causing concentrations to rebound, ultimately a loss.
Double loss: Wasting 3 to 6 months of vacancy with no way to verify if the new home is safe.

We provide highly credible test reports with all treatment processes complying with environmental and safety regulations. Service coverage includes residences, offices, commercial premises, public institutions, schools, elderly homes, hotels, restaurants, etc. Whether newly renovated or with new furniture, we cover them all. We effectively break down and remove formaldehyde and other harmful gases, transforming air risks into verifiable data – professionalism for your peace of mind.
Australian Scientific Certified Technology
Operates continuously for 24 hours, unaffected by light, decomposing formaldehyde all day long. Passed OECD toxicology guidelines and oral/skin/eye mucous membrane safety tests. Tested on various materials with no corrosion or damage to your expensive furniture and walls.
Dust Removal for Better Treatment
Fine dust after renovation sticks to surfaces, walls, and fabrics. Spraying directly gets blocked by dust. We first use HEPA-filter-equipped vacuum cleaners to remove allergens, ensuring the formula contacts the pollution source without loss of effectiveness.
Data-driven Results
Simultaneously test formaldehyde (HCHO) and total volatile organic compounds (TVOC) to avoid the blind spot of “formaldehyde passing but TVOC exceeding.” Post-treatment retesting with clear reports showing improvement, so you see the effect of every dollar spent.

Professional Steps of Formaldehyde (VOC) Removal Service
After treatment, VOCs (including formaldehyde) levels are significantly improved. However, some treated building materials and new furniture may still release small amounts of formaldehyde in the first week. To avoid concentration build-up, keep wardrobes, cabinets, and windows well ventilated.

What is the “acceptable” formaldehyde concentration?
Hong Kong’s indoor air quality guideline (e.g. in offices and public places) sets reference levels for formaldehyde: recommended max ≤ 0.08 ppm. Higher standards like “Good” or “Excellent” exist to avoid adverse reactions.
Even furniture/materials claiming to be eco-friendly may accumulate formaldehyde exceeding standards by 25 times due to adhesives, panels, and coatings. Thus, it’s safer to conduct formaldehyde/TVOC testing after renovation and adopt treatment accordingly, followed by retesting to confirm indoor air quality reaches acceptable levels.

Formaldehyde (VOC) Removal Pricing
Why don’t we reveal a fixed price?
Each unit’s situation is unique. Formaldehyde removal is not a “spray and done” standardized service but a process centered on testing and verification. Random fixed prices may lead to cutting crucial steps or unexpected on-site additional costs causing big budget gaps.
We provide clear quotes and plans based on your unit’s condition, arranging treatment only after your confirmation, avoiding “low quotes then extra charges” situations.
Pricing factors include:
- Usable floor area and layout (1-bedroom, 2-bedroom, duplex, etc.)
- Quantity/density of woodwork/custom cabinets
- Scope (entire unit, key rooms, cabinet interiors) and treatment duration
