A composition which provides enhanced removal of aldehydes from the air of the building interior. The composition includes an amino silane and a multivalent metal carbonate and is especially suitable for adding to building product board substrates, such as acoustical ceiling panels and gypsum wallboards. The composition of the invention can be applied during manufacturing or can be post applied to already constructed room surfaces. The composition provides longevity of aldehyde removal heretofore unachieved.
