Hello, there are plenty of indoor air pollutants to beware of, such as:                      Asbestos: Asbestos is a mineral often used as a building material because of its strength and resistance. It is used in ceilings, floor tiles, and so on. However, asbestos can turn out to be dangerous as it may get damaged over time, leading to asbestos fibres being emitted into the air and becoming a health hazard.
Stoves: More than 2 billion people in the world’s population—the vast majority of whom reside in rural areas and urban slums in developing countries—cook their meals by burning coal and biomass fuels. Indoor burning releases dangerous fumes, like carbon monoxide, which then may cause carbon monoxide poisoning.
Cleaning products: Many cleaning products, like floor cleaning liquids, can also contain a host of different toxic chemicals, which may include phthalates, monoethanolamine, diethanolamine, and triethanolamine, connected with health problems from asthma to cancer.
Mould: Moulds are types of fungi that trigger allergies and respiratory diseases. It requires a moist and humid environment for its growth on walls, floors, and even ceilings. This is even more hazardous for those whose immune systems are already poor, for it can really bring down the health conditions.

Although there are plenty of sources of indoor air pollution, the above are some of the more common. You can, however, take small steps to ensure that your indoor environment is a healthy haven for your children.
