Indoor Air Pollution: A Growing Concern

Indoor air pollution refers to the presence of harmful substances or contaminants in the air of enclosed spaces, such as homes, offices, or other indoor environments.

Especially in heavily polluted urban areas, many people believe that indoor air is less polluted than outdoor air. This is a misconception..

It is estimated that indoor air can be 2 to 5 times more polluted than outdoor air. Studies have shown that indoor environments contain numerous sources of pollutants that add to outdoor air pollution, such as:

Wall paints
Furniture coatings
Mold and humidity buildup
Detergents and chemicals

The Impact of Indoor Air Pollution

Indoor air pollution has only been studied relatively recently, but the problem has a significant impact on the lives of many people.

The World Health Organization (WHO) estimates that several million deaths per year are attributed to poor air quality in homes and other indoor environments.

Legal limits vary over time and according to the regulatory authority or agency, but the most authoritative guidance can be taken as a reference.

The following links are a starting point to delve into the phenomenon of indoor air pollution (or IAQ Indoor Air Quality), and derive data on the impact of the problem, recommended limits, and recommendations/guidelines.

Photocatalytic Filtration:
a Powerful Solution

Photocatalytic filtration is a photochemical reaction in which a catalyst (titanium dioxide) irradiated by light decomposes pollutants containing carbon, i.e., volatile organic compounds (VOCs), which constitute the majority of harmful substances present in the air.

It is one of the best methods of air purification because it does not simply filter pollutants (in the traditional sense of "trapping") but destroys them. Therefore, it is effective even against substances too small to be physically blocked by a filter, such as bad odors.

In addition, titanium dioxide has recognized bactericidal properties, and therefore, titanium dioxide photocatalytic filters are also highly effective in removing airborne viruses and bacteria (see "the bactericidal power of titanium dioxide.").
