Irritation after decoration is usually caused by volatile organic compounds, requiring a professional deep cleaning of the entire house to thoroughly clear fine dust from hidden corners, combined with sustained, high-efficiency ventilation; avoid masking odors with just air freshener.
The invisible killer of air pollution
Eye irritation or coughing when moving into a new home is mainly caused by volatile organic compounds (VOCs) and formaldehyde released from wall paint, custom cupboard plywood, and glue. In Hong Kong's enclosed living spaces, the concentration of these harmful gases easily accumulates. Relying solely on opening windows or using air freshener is difficult to eradicate; a systematic professional approach must be taken.
Defining the scope of professional cleaning and DIY
When handling decoration residues, you should clearly distinguish the differences between DIY and professional technology. Daily cleaning is limited to diligently opening windows, cleaning dust filters, and placing plants. However, deep plywood gaps, fine dust residue on wall paint, and chemical contamination all rely on professional technology for treatment.
- DIY suggestions: Keep the whole house ventilated, and periodically clean air conditioner filters.
- Professional handling: Remove fine dust in hidden wall corners, perform chemical residue purification targeting decoration materials, and maintain with high-specification professional instrument equipment.
Safety precautions
Do not recklessly spray chemical sprays of unknown composition onto wooden furniture, as this may lead to surface damage or cause secondary chemical reactions. For the decoration fine dust in a new home, you need to use professional tools with anti-static functions to perform deep dust collection, so as to avoid construction dust suspending in the air and causing secondary pollution.
