摘要
A filter for removing aldehyde-like VOCs from indoor air is disclosed. The filter includes a casing acting as a container. The container comprises two air-permeable opposite walls through which a volume of said indoor air flows and houses one or more natural polyphenols and a catalyst or catalytic agent. The filter acts as an absorption filter, reacting irreversibly with the aldehyde-like VOCs of the indoor air. The natural polyphenols are powdered polyphenols selected from resveratrol (3,4',5-trihydroxystilbene), resorcinol (1,3-benzenediol), pyrogallol (1,2,3-benzenetriol), phloroglucinol (1,3,5-benzenetriol) and hydroquinone (1,4-benzenediol), or combinations thereof. The catalyst or catalytic agent is a solid sulfonic acid. A mixture of the natural polyphenols and said catalytic agent are present, in the container, as compacted block elements. An air-purifying/decontaminating device comprising the filter and a method for removing, from indoor air, amine-like VOCs and ammonia, as well as aldehyde-amine derivatives, are also disclosed.
