Odor filtering device
First Claim
1. An odor filtering device for space dispensing a volatile oil comprising a substantially rigid substrate means having voids of substantially uniform size throughout for entraining an essential oil therein, the size of the voids between about 10 and 150 microns in cross-section and a volatile essential oil entrained in the substrate, the oil comprising a mixture of a malodor counteractant capable of producing reversible selective anosmia and a perfume accelerator, whereby said essential oil is volatilized to the space at a predetermined rate.

Abstract
An odor filtering device for space dispensing a volatile oil by soaking a porous substrate with a malodor counteractant composition. The exposed surface of the substrate permits evaporation of malodor counteractant creating an internal vapor pressure differential which drives the counteractant from the interior of the substrate to the surface to replace the surface loss. Particular devices are formed and arranged to permit controlled release of the malodor counteractant over an extended period of time.

- 17. An odor filtering device for space suspensing a volatile oil comprising a substantial rigid substrate formed from a polyethylene material with voids of substantially uniform microscopic size throughout, the size of said voids therein of from about 30 to 90 microns in cross-section and an essential oil comprising a malodor counteractant capable of producing reversible selective anosmia admixed with between about 25 and 75 weight percent of a perfume accelerator based on the weight of said mixture entrained in said voids, whereby said essential oil is volatilized to the space at a predetermined rate.
