Tourism (large hotels)

Travellers frequently staying in hotels are subjected to a large variety of allergens and pathogens (mould, fungus, bacteria, viruses, etc.)

The threat may be worsened by present cleaning protocols that use toxic chemicals like bleach. Many people suffer from allergies, which are exacerbated by traditional cleaning products and poor air quality .

Plus, germs can be spread through airborne means, direct contact (hands) and contaminated surfaces, as well as in the food and water.
