However, current trends are changing as health and indoor air quality become one of the most important criteria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why formaldehyde emission control standards such as E1, E0 or international certifications are increasingly focused on in the interior materials industry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These standards help evaluate the amount of formaldehyde a product may emit during use, thereby providing a clearer basis for consumers to choose appropriate materials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What Matters Is Not Whether It Exists, but How Much<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most common misconceptions is that a product or material is completely formaldehyde-free.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In fact, what modern industry is aiming for is not complete elimination, but low and safe emission control according to recognized standards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, when choosing interior materials, the important question is not:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>&#8220;S\u1ea3n ph\u1ea9m n\u00e0y c\u00f3 formaldehyde hay kh\u00f4ng?&#8221;<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;<em>S\u1ea3n ph\u1ea9m n\u00e0y ph\u00e1t th\u1ea3i formaldehyde \u1edf m\u1ee9c n\u00e0o v\u00e0 c\u00f3 \u0111\u01b0\u1ee3c ki\u1ec3m \u0111\u1ecbnh theo ti\u00eau chu\u1ea9n \u0111\u00e1ng tin c\u1eady hay kh\u00f4ng?&#8221;<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Air Quality Starts with the Materials We Choose<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every day, we spend 80% to 90% of our time in closed spaces such as home, office or school.
