The Science of PowAir

PowAir odour neutralising products consist of complex formulations representing a variety of chemical compounds and offering different functionalities, both structural and chemical.

The technology behind PowAir was initiated over 25 years ago. The scientist (who was eventually credited with the invention of PowAir) became fascinated when he observed that when terepenes were diffused into the environment, emission’s and odours were reduced. Inspired by this finding, further evidence showed that the odours were not just masked but permanently removed.
The result was a set of specialised formulations that neutralise a wide spectrum of organic and inorganic odour problems – effectively, efficiently and permanently. Manufactured under strict quality controls, the components of PowAir are generally recognised as common in the food industry and have 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=CH2*


Terpene Characteristics


  • Terpenes have anti-bacterial, antifungal and anti-septic 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.

How it works?

How does PowAir work to eliminate your nasty odour problems? Well it all happens naturally on a molecular level. When you’re using our blocks, gels or sprays, PowAir evaporates and disperses into the air. The rate of evaporation and dispersion is controlled by ambient conditions, such as air flow, temperature and humidity – in addition to the amount of product used. Scientifically speaking there are three methods of odour neutralisation that occur: adsorption, absorption and chemical reaction…



First, electrostatic and molecular forces cause PowAir molecules to attract and bond with odour molecules – this is adsorption.



Absorption occurs when a PowAir molecule soaks up an odour molecule, which neutralises the odour as a result.

Chemical Reaction

And when a chemical reaction occurs, the combined PowAir and odour molecules react and change to create a neutral compound, thereby eliminating the odour.
