Odours are always present in our surroundings. When the concentrations are too high we experience this as smell. There used to be a time when odour or smell was regarded as inevitable and accepted as a matter-of-course. 

Those times are definitely past. Environmental awareness and social responsibility have quite literally brought us nose to nose with the issue of odour and smell nuisance. Separate from discussions as to what the difference is between odour and smell, government has in the meantime adopted measures designed to guarantee clean, odourless air.

This has presented many businesses with the necessity of making provisions that are not only effective but also affordable.
