E0: The product does not contain Formaldehyde

E1: Formaldehyde concentration is not greater than 0,124 mg/m3 or not greater than 9 mg/100g

CARB2 limits Formaldehyde emissions as follows:

– Hardwood plywood (HWPW): 0.0500ppm

– Medium density fiberboard (MDF): 0.11 ppm

– Chipboard (PB): 0.09ppm

To limit exposure to Formaldehyde gas, it is necessary to use alternative products to Formaldehyde, such as Formaldehyde-free wood glue or low-VOC water paint (Volatile Organic Compound - volatile organic compounds) or avoid Buy products with strong chemical odors

The living environment needs to be airy

Living spaces need ventilation to dilute Formaldehyde concentrations. We need to follow the following 3 principles to create an open living space:

  • Open windows and doors regularly to ventilate the house.
  • Use exhaust fans in kitchens, bathrooms and areas with many products containing Formaldehyde.
  • Install mechanical ventilation if necessary.
