"Zero formaldehyde floor" is not credible
Don't be fooled by the slogan of "zero formaldehyde floor", this is just the marketing strategy of the merchants. E0 grade products are not completely free of formaldehyde, but the formaldehyde emission is low, ≤ 0.5 mg/L. ..
E 1 grade products are safe.
When purchasing wood floors, choose products that meet the national standard E 1, and the formaldehyde emission is ≤1.5 mg/L. Such products are safe and can be used with confidence.
Smell the smell of wood.
Let the merchant show the quality inspection report and smell the wood aroma. If there is a pungent smell, don't choose it. This is because the formaldehyde emission is too high, which is harmful to human health.
