Universities, startups, and suppliers with solutions in air care and freshening.
Air care and freshening organizationsAir care and freshening reaches from the sorbent and the catalyst to the device holding them and the fragrance released. On Halo it spans 7 groups, including metal-organic frameworks for VOCs, catalytic and UV air treatment, and filter media and sorbents.
Stage of development. Work on air care & freshening on Halo is split between university programs and companies. 50% of the solutions are in market. University of Alberta has the most, followed by University of Connecticut. Co-development and licensing are the usual partnering routes, and about 56% of the solutions that state terms offer pilot engagements.
Photocatalysis moving into consumer devices. Device makers are adopting photocatalytic oxidation to treat air with no consumable filter. One design pairs titanium dioxide with silver nanoparticles as a sanitizing coating (Clairco). Another drives the same chemistry with UV LEDs for pathogen inactivation (Miami University, Ohio).
Engineered sorbents for specific pollutants. Researchers are tuning porous materials to single target molecules. One uses a metal-organic framework aimed at formaldehyde removal (SquairTech). Another builds ultralow-density mesoporous graphene aerogels to adsorb volatile organic compounds (University of California, Santa Cruz).
Treating odor at its source. Formulators are attacking malodor chemistry at source. One technology acts on both the chemical and the biological source of malodor (Wizard Labs). Another uses reactive chemistry to eliminate odor compounds directly (Advanced Vascular Access Systems).
Air care covers products that remove, neutralize or add scent to indoor air, and the chemistry and devices behind them. It spans volatile organic compound capture, malodor neutralization as distinct from masking, fragrance delivery and controlled release, and the filtration media that hold any of it. Consumer brands, appliance makers and building product suppliers are the buyers.
