4. Practical steps for removing formaldehyde in the cloakroom
1.Pre-test detection: Use a professional formaldehyde detector, focusing on detecting data after 12 hours of sealing, national standard requirements are ≤0.08mg/m³
2.Emergency handling: Take it immediately after finding that the standard exceeds the standard: - Keep ventilated for 24 hours - Place double amount of activated carbon (50-100g per square meter) - Turn on the air purifier
3.In-depth governance:- High temperature fumigation twice a week (temperature above 50℃) - Spray photocatalyst to treat the surface of the plate - Install a small fresh air system
4.Long-term maintenance:- Replace activated carbon every month - Keep humidity 40-60% - Professional testing every quarter

| Negative ion technology | Decompose gaseous pollutants | Continuous purification | Overall environment |
6. Experts’ special reminder
1. Avoid using vinegar, pineapple and other "earth methods". These can only cover up the odor and cannot decompose formaldehyde.
2. It is recommended to clean the clothes first and then put them in the cloakroom. The formaldehyde contained in textiles is easy to soluble in water.
3. When choosing environmentally friendly building materials, identify the ENF grade (≤0.025mg/m³) or F4 star grade (≤0.03mg/m³) standards.
4. It is recommended that the formaldehyde concentration be controlled below 0.06mg/m³ for pregnant women and children.
Through the above systematic solutions and regular testing, the formaldehyde problem in your cloakroom will be effectively controlled. It is recommended to combine various methods to achieve the best results.
