Museums must have suitable spaces for their art to be preserved in and comfortable areas for guests visiting the works on display.
Air quality is important both to ensure that customers are comfortable and that artwork is kept in optimum conditions.
Environmental factors are a critical element of the rooms in these buildings or in any other building preserving valuable objects in order to avoid irreversible damage to the artwork.
The most important factors to be considered are temperature, humidity and microorganisms that can cause chemical and physical changes, as well as biological damage in the artwork. All bodies absorb water and are therefore exposed to these types of factors.
Air quality is very important in museums because of the effects of pollutants:
Acidic gases: damage metals, stone, textiles, leather and photographs.
Oxidising gases: cause premature ageing and, in particular, mummified remains suffer a sharp increase in corrosion.
Microbiological contaminants: the action of insects and microorganisms generates acids and enzymes that affect the remains.
Airborne particles: particles with acidic properties generate corrosion, and particles with alkaline properties damage paint and textile fibres.
Outdoor air must be perfectly filtered inside the museum so that indoor air quality is excellent and allows the artwork on display to be preserved properly.
