Abstract

See full text

Disclosed are substrates suited for dispensing air treatment chemicals upon being heated. Granular particles, preferably sand with a phenolic binder, are adhered together to form a substrate body having a network of pores. A volatile air treatment chemical is disposed in the pores. The particle size and pores are such that the smaller particles of the substrate are grouped at one end, preferably an end adjacent to a projecting nose. This structure tends to wick the volatile air treatment chemical towards the nose, and heating that area can lead to efficient, and rechargeable, dispensing. Methods for using such substrates, and methods for forming such substrates, are disclosed.
