An energized air freshening apparatuses comprising perfume mixtures having an olfactive index and vapor pressure distribution for improved diffusion into a space methods thereof are provided. The energized air freshening apparatus may include a delivery engine containing the volatile perfume mixture, a fluid transport member, and an evaporation assistance element such as a fan that is configured to move a volume of air over the fluid transport member to facilitate evaporation of the perfume mixture into the atmosphere.

The present invention relates to a method for screening a candidate substance for an unpleasant odor masking agent from among test substances using an olfactory receptor that is responsive to an unpleasant odor-causing substance. The screening method of the present invention includes the steps of: adding a test substance and an unpleasant odor-causing substance to an olfactory receptor polypeptide selected from the group consisting of OR2L3 and polypeptides which comprise an amino acid sequence having at least 80% identity to an amino acid sequence of OR2L3 and are responsive to the unpleasant odor-causing substance; measuring a response of the olfactory receptor polypeptide to the unpleasant odor-causing substance; and identifying the test substance that suppresses the response of the olfactory receptor polypeptide as a candidate substance for the unpleasant odor masking agent based on the measured response.

A ventilation system for removal of aerosols including bacteria and viruses such as the COVID-19 Coronavirus, and airborne debris from dental/medical operatories is provided. This ventilation system is comprised of (1) a stationary hood, secured at a specific distance above a patient that pulls contaminated air from the operatory, (2) ducting that carries the contaminated air away from the operatory, (3) a UV Ozonator that treats the air and cleans it of viral and bacterial aerosols and airborne debris before (4) expelling it to the outside through a specified length of terminal duct. The combination of certain embodiments in this invention create an effective means of aerosol and airborne debris removal in dental/medical operatories or other indoor spaces.
