What is the difference between E0 and E1 grade lumber? What are the standards?

2025-10-16

Homeowners who have experienced renovations know that wood panels are one of the materials most likely to produce formaldehyde during renovations, so it's crucial to choose panels with low formaldehyde content. Currently, there are three environmentally friendly grades of wood panels on the market: E0, E1, and E2. Next, let's discuss the differences between E0 and E1 panels and the standards. If you're unsure, follow along as we learn more.

1. Environmental protection level E1

According to national environmental standards, indoor flooring must meet the E1 environmental rating. In other words, E1-rated flooring is safe and environmentally friendly, and therefore poses no harm to the human body. When purchasing flooring, it's important to consider its quality and formaldehyde emissions. The E1 environmental standard is a mandatory national safety standard. To meet the national E1 environmental rating, a floor must have a formaldehyde content of 1.5 mg/l.

2. Environmental protection level E0

E0 is an international standard and is environmentally friendly. A formaldehyde content of 0.5mg/l is a safe numerical value for E0. In other words, the formaldehyde release concentration per liter of space is less than 0.5mg. According to relevant data, the formaldehyde content in our daily drinking water is 0.9mg/l. E0-grade boards are very safe and environmentally friendly, and the formaldehyde release amount is even less than the maximum level in drinking water.
