ONA – Odour Neutraliser – Remove Odours Safely, Naturally & Permanently

ONA Odour Neutraliser has been destroying odours effectively for many years and is used in commercial applications worldwide. ONA was originally developed for use in industrial applications to neutralise strong odours in sewage treatment plants, rendering plants and chemical plants. It uses three processes: absorption, adsorption and the “Pairs” Theory to virtually cancel out most organic and non-organic odours.

ONA’s formulation is designed to attack any type of odour, regardless of type or source. Because it is a wide spectrum formulation, it will neutralise virtually every non-organic and organic odour, and leave only a clean, fresh scent.

ONA Applications

ONA’s powerful odour neutralising capability makes it ideal for most commercial applications. Regardless of the source, it will get the job done. It is ideal for:

• Hotel / Motel rooms – ONA Breeze, ONA Gel

• Sports Locker Rooms – ONA Block, ONA Mist and ONA Mist Dispenser

• Garbage Areas – ONA Gel

• Confined Areas – ONA Gel, ONA Block

• Compost Areas – ONA Liquid

• Heating Vents and Ducts – ONA Block, ONA Gel

• Jobsite Odours – ONA GelOdour Neutra

• Mildew Odours – ONA Liquid, ONA Gel

• Smoke Odours – ONA Gel, ONA Mist

• Food Odours – ONA Gel, ONA Mist, ONA Breeze

• Old Cellars – ONA Gel, ONA Breeze

ONA is available in five fantastic fragrances; Apple Crumble, Fresh Linen, Polar Crystal, PRO and Tropics.

The Science of ONA

The ONA odour neutralising products consist of complex formulations representing a variety of chemical compounds offering different functionalities, both structural and chemical. The technology behind ONA Odour Neutraliser was initiated over 25 years ago. The scientist who invented ONA became fascinated when he observed that terpenes, when diffused into the environment, reduced odours and unwanted emissions.

Inspired by this finding, further evidence showed that the odours were not just masked but permanently removed. The result was a set of specialized formulations that neutralise a wide spectrum of organic and inorganic odour problems — effectively, efficiently and permanently. ONA formulations have been scientifically engineered to be environmentally safe. ONA is manufactured under strict quality controls to ensure a safe and non-toxic product. The components used to make ONA are generally recognized as safe and have been commonly used in the food and cosmetics industries with a long history of safety.


Terpenes are widespread in nature, mainly in plants as constituents of essential oils. Many terpenes are hydrocarbons, but oxygen-containing compounds such as alcohols, aldehydes or ketones (terpenoids) are also found. Their building block is the hydrocarbon isoprene, CH2=C(CH3)-CH=CH21.


• Terpenes have anti-bacterial, antifungal and antiseptic properties.

• Terpenes have oxygenating properties (increases oxygen level).

• When diffused into the environment, terpenes have been found to reduce airborne chemicals and bacteria.

• Terpene characteristics appear to either destroy the odour molecule or convert it to a more acceptable level.


There are three mechanisms of action that can occur, based on the chemical and physical natures of each terpene and active ingredient versus the organic and inorganic volatile compounds.

Adsorption — All VOCs and odorous compounds have a solubility factor in ONA active ingredients. This solubility will allow the VOC compound to solubilize itself in the presence of ONA, relative to the chemistry of the emission, temperature, pH, and pressure of the environment. Adsorb: To collect and hold (gas or vapor) in the surface of a solid.

Absorption — The active molecules in ONA will attract or come into contact with low molecular weight or volatile compounds (VOC’s). These VOC’s will enter and bond with the ONA active ingredients to eliminate odours. Absorb: To retain wholly, without reflection or transmission, what is taken in.

Chemical Reaction (The Pairs Theory2) — This involves the permanent bonding of the odorous molecule (VOC) and the ONA active ingredients reactive sites. This mechanism transforms the pollutant in its basic properties. As a result, odour disappears. ONA Chemical Reaction

The affinity of the different odorous compounds (VOCs) with ONA is directly relative to their chemical composition and physical state. For example, a hydrogen sulfite can have a great affinity for certain sites of the ONA active ingredient. It can either bond electrostatically, or react in comparison to its relative solubility. This means different components will be neutralised by one mechanism compared to the other two, or a blend of each of the three.

The bottom line is ONA is not a masking agent but offers a safe, effective way to permanently eliminate odours and emissions
