Testing · Singapore
Not sure? Measure first.
A S$100 testing visit gives you room-by-room formaldehyde readings against the WHO guideline — so you decide with numbers, not smell. Waived if you go ahead with formaldehyde removal.

What your report tells you
Each room gets a reading at breathing height under closed-up conditions, plus spot checks inside wardrobes and cabinets where emissions concentrate. Against the WHO guideline of 0.1 mg/m³, results fall into three bands:
- 0.06mg/m³ and below — comfortably safe; no action needed.
- 0.06mg/m³ to 0.10mg/m³ — within the guideline; re-check after a few weeks if the renovation is recent, or treat if infants or pregnant women are moving in.
- Above 0.10 mg/m³ (0.08 ppm), such as 0.18mg/m³ — elevated; source treatment is the reliable fix, and your S$100 is waived if you go ahead with it.
The report is yours either way — including if the numbers say you don't need us, in which case that is exactly what we tell you.
Testing questions
How much does formaldehyde testing cost in Singapore?
Formaldehyde.SG’s testing-only visit is S$100: room-by-room readings with a calibrated professional meter and a written report benchmarked against the WHO 0.1 mg/m³ guideline. The full fee is waived if you go ahead with removal.
Can I just buy a formaldehyde meter online instead?
Consumer handheld meters (typically S$20–80) use semiconductor sensors that cross-react with alcohol, cooking fumes, perfume and humidity — side-by-side tests routinely show them reading several times too high or too low. They are fine as a rough trend indicator, but not something to base a move-in decision on. Professional electrochemical meters, calibrated against reference standards, are what testing services use.
When does testing-only make sense instead of booking removal?
Test first when the situation is ambiguous: a renovation completed more than a year ago, only one or two new furniture pieces, no noticeable smell, or a landlord/developer dispute where you need numbers. If your renovation just finished and the smell is obvious, levels are almost certainly elevated and most owners book treatment directly.
How is the test conducted?
We ask you to keep windows and doors closed for 8–12 hours beforehand (overnight is ideal) so readings reflect real living conditions. On the visit we measure each room at breathing height, plus inside wardrobes and cabinets — the highest-emission points — and you receive the report on the spot.
