Experts recommend that consumers should reasonably control the amount of decorative and construction materials used in the house. The concentration of formaldehyde in the air not only depends on the emission level of each type of material but also on the total amount of materials used in a given space.
Materials with higher formaldehyde emissions should be used more limitedly. If large quantities are required in closed spaces, products with low formaldehyde content or not containing formaldehyde should be prioritized to reduce the risk of indoor air pollution.
Experts also emphasize that opening windows for ventilation is the simplest, most effective and economical solution. Increasing fresh air flow from the outside will help push air containing formaldehyde out, thereby quickly reducing the concentration of this substance in the living space.
In addition, consumers can apply some additional support measures. Air purifiers with formaldehyde treatment functions can break down this substance into less toxic compounds through chemical reactions. When choosing a product, consumers need to pay attention to treatment efficiency as well as the safety of the device.
Activated carbon is also a popular solution thanks to its ability to absorb formaldehyde molecules in the air. Users can place activated carbon bags in many locations in the room, but they need to be replaced periodically because when saturated, activated carbon can release back the absorbed substances.
For families with fish tanks or aquariums, experts say formaldehyde is easily soluble in water. Air pumps can be used to increase the exchange process between air and water, helping a part of formaldehyde dissolve into water in the tank. However, to maintain efficiency, periodic water changes are needed. This is only a supportive measure and cannot replace ventilation or the use of low-emission materials.
