Why Previous Deodorization Solutions Failed

For decades, many products have attempted to remove toilet odors at the source. While the concept is not new, these solutions have consistently failed for one critical reason: the exhaust pathway.

Most approaches rely on either external ducting or onboard filtration. External ducting requires drilling through floors, walls, or fixtures—making installation intrusive, costly, and impractical at scale. Filtration systems, on the other hand, simply circulate treated air back into the restroom. They remove odors slowly, lose effectiveness over time, and require ongoing filter replacement. As a result, they function as marginal add-ons rather than true solutions.

ODORUN solves what others could not—the exhaust pathway itself. By utilizing an existing toilet mounting hole as a dedicated exhaust channel, ODORUN integrates directly with the building’s drainage and DWV system—without drilling, structural modification, or replacing the toilet.

Odors are physically extracted from the bowl and expelled through the building’s ventilation system. No filters. No fragrances. No consumables.

For the first time, toilet odors are not masked or treated—they are removed entirely from the building.

How ODORUN Breakthrough

By utilizing an existing toilet mounting hole, ODORUN’s patented design generates negative pressure to extract odors directly from the bowl into the drain pipe, where they are conveyed out of the building via the DWV (Drain-Waste-Vent) system.

Why Odor-Free Matters

  • Experience

    Odors immediately shape how a space feels. Even brief smells reduce comfort and willingness to stay. Odor-free restrooms remove this friction point—elevating everyday use and guest experience in a way users feel instantly.

  • Health

    Toilet odors can signal airborne microorganisms and plume dispersion. Fragrances may mask the smell but do not stop spread. Removing odors at the source supports cleaner, more transparent indoor air.

  • Building Envionment

    How a building manages odors reflects its environmental standard. Odor-free restrooms support higher indoor air quality and a more refined baseline aligned with modern, future-ready buildings.
