One, the substances causing odors after home decoration slowly release into the air over time, and sometimes they can still be released a year later. However, if there is poor ventilation after decoration, these odor-causing substances can accumulate at high concentrations in the room, resulting in a strong smell. Ventilation and activated carbon adsorption can reduce the concentration of these odor-causing substances and quickly eliminate the heavy odor. However, it is impossible to completely eliminate the odor. Activated carbon is a product that addresses the root cause, while air fresheners and similar products are more like temporary solutions. They can mask odors but cannot eliminate them.

Activated carbon has its limit in adsorption. If one gram of activated carbon can adsorb one gram of organic matter, then only a few tens or hundreds of grams can adsorb an equivalent amount of odorous substances, which is far from sufficient to eliminate household odors. Moreover, activated carbon not only adsorbs these odorous organic substances but also absorbs moisture in the air. Therefore, a small amount of activated carbon is insufficient to remove the strong odors from newly decorated rooms. It can only be used in small spaces such as refrigerators, shoe cabinets, and wardrobes. For larger spaces, methods like filling under the floor, dispersing in workshops, and rooms can be employed. Consequently, when using activated carbon to remove odors, it is important to note regular maintenance or replacement, as the saturated carbon may release the substances it has adsorbed.

Always follow the principle of sufficient contact when using activated carbon. It can only adsorb odorous substances after coming into contact with them, so avoid using it with packaging and ensure good ventilation.

Additionally, the activated carbon's strength is excellent; it won't break or powder in normal conditions, maintaining its integrity over time. As long as the activated carbon is not saturated, it retains its adsorption capability. However, it is still recommended to store it in a sealed container.
