Furniture can raise indoor air contaminants with toxic emissions of VOC and formaldehyde.. While furniture is classified as a subject of safety and has quality labeling, there is a lack of domestic regulations related to contaminant emissions with the exception of sinks. When looking at the analysis on environment-related patients related to the smell or odors from furniture every year, patients suffering from asthma, allergic rhinitis, and atopic dermatitis are on the rise. Likewise, because there was an urgent need to prepare control standards, there was a prior notice of legislation for the introduction of a contaminant emission labeling system from 2010 onwards. This study conducted an analysis on the emission characteristics of VOCs and formaldehyde, an indoor air contaminant emitted from furniture. After an analysis was conducted on contaminant emission characteristics on conventional furniture versus eco-friendly furniture that can reduce harmful elements with closets, which are special-offer products, and office desks which are general market products, improvements were shown which indicate materials were working continuously to reduce indoor air contamination factors. Because of the comparative analysis on characteristics of the furniture of which has eco-friendly engineering against conventional furniture engineering, contaminants had been reduced in furniture using the eco-friendly engineering methods.
