In many large cities, the air is becoming so dirty that people look for ways to escape it into somewhere with clean air. Many travel agencies start to market their holidays as fresh air tourism.

Nose plug filters are being used to combat pollen, pollution, pet allergen, dust or fumes. In cities, these are now frequently seen.

Artificial noses might be the future of disease discovery. Research has found that scents can pick up diseases such as Parkinsons.

Artificial noses are being created through training neural networks. These are later being incorporated into A bioelectronic nose, an intelligent chemical sensor array system coupled with bio-receptors to identify gases and vapours, resembles mammalian olfaction by which many vertebrates can sniff out volatile organic compounds can give back the sense of smell for those with anosmia.

Every new home will be assessed through the property’s air quality score. Future Climate Info (FCI) – one of many UK companies that compile environmental reports for solicitors – is the first to include pollution levels as standard, and at no extra cost.

Air monitors can be used with HPC to forecast potential increases or decreases in pollution and the possible reasons and consequences.

Potential for cities to use white smells to mask bad odours and create less smelly urban areas.

New sensors that similiarly to smoke detectors become ubiqituous in the home sensing particulates.

Vaping alcohol and making it inhalable is a way to ingest drinks through breathing it rather than drinking it in liquid form. Bars may be built around their inhalable experiences.

Different odours have the potential to impact productivity for individuals, what if buildings and the AC was built with scent in mind to enhance the efficiency of workers. Perhaps, this can be done by including nootropics in the air we breathe.
