Museums must have suitable spaces for the preservation of their art and comfortable spaces for the guests visiting the works on display.
Air quality is important, both for the customer’s comfort and for the perfect condition of the artworks.
The environmental factors in the rooms of these buildings or in any other that contain valuable objects for their preservation is a critical element to avoid irreversible damage to the works.
The most important factors to be taken into account are temperature, humidity and microorganisms that can cause chemical and physical changes, not to mention biological damage in the works. 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 or photographs.
Oxidising gases: cause premature ageing and, in particular, mummified remains suffer a sharp increase in corrosion.
Microbiological pollutants: 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 paints and textile fibres.
Outdoor air must be perfectly filtered inside the museum so that indoor air quality is excellent and allows for proper preservation of the works displayed.
