Beware of the "Invisible Killer": What You Must Know About Environmental Ratings and Formaldehyde in Wood Flooring

Introduction: The formaldehyde in wood flooring mainly comes from the adhesives used. It's invisible and intangible but directly affects your family's health. When choosing, don't just ask "does it smell?"; you must look for authoritative environmental ratings.

Body:
Whether it's engineered wood flooring or laminate flooring, adhesives are inevitably used in the production process – the primary source of formaldehyde.

China's current national standards classify the environmental ratings of wood flooring into three main levels: E1, E0, and ENF.

• E1 Grade: This is the mandatory national environmental standard, the minimum entry requirement. Formaldehyde emission must be ≤0.124 mg/m³.

• E0 Grade: This is a stricter requirement, with formaldehyde emission ≤0.050 mg/m³. It's currently the mainstream choice for mid-to-high-end products.

• ENF Grade: This is the highest national standard currently, with formaldehyde emission ≤0.025 mg/m³. It offers the best environmental performance, especially suitable for homes with pregnant women or infants.

Buying Tips:

1. Check Reports: Directly ask the seller for the product's environmental and performance test reports to confirm the formaldehyde emission level.

2. Smell Test: Open the packaging and smell. A faint, pleasant woody smell suggests low formaldehyde. If the smell is pungent and unpleasant, definitely do not buy.

3. Choose Brands: Prioritize well-known brands with good reputations to avoid being "ripped off" by cheap, inferior products. Excessively low prices (e.g., below 50 RMB/m²) often indicate potential quality risks.
