In a home, excess humidity can be caused by capillarity, infiltration or condensation. This last point is the only one on which the occupants of a home can act as quickly as possible by changing certain habits. To combat this humidity, certain plants are particularly effective. They absorb moisture and prevent the appearance of mould.

Humidity can appear as fog on windows and dampen walls.  In addition to deteriorating walls, too humid air   can lead to mould development. However, some indoor plants can limit condensation and act as a treatment against humidity.

Why does the house experience condensation?

When water vapour in the ambient air comes into contact with cold surfaces, condensation forms and the vapour turns into water, creating fine droplets on the surfaces. Condensation problems can occur on new or old building materials. Certain human activities, such as simply taking a hot shower, breathing, sweating or cooking food in the kitchen, can increase the level of humidity. This represents the level of moisture in the air. Thus, the water vapour ends up condensing, causing a humidity problem in the room.

What factors contribute to condensation problems?

Several factors can contribute to the phenomenon of condensation. Poor ventilation in the house, insufficient ventilation or a breakdown in the ventilation system, poor insulation or even the passage of warm air into cold air are all potential causes of condensation in a house.

What are the consequences of a condensation problem?

As a result of cooling by warm, humid air, condensation can appear as traces of moisture on walls, ceilings and mirrors. Result ?  Traces of mould appear on the walls  , paint is peeling and wallpapers are peeling off. In addition to its unsightly nature, mould can pose a danger to the health of residents. Indeed, these microscopic fungi multiply and can release spores and mycotoxins. These toxic substances can irritate the respiratory tract and cause asthma, rhinitis or bronchitis.

What plants help dehumidify the air?

To regulate the level of humidity in the air and eliminate mould, certain indoor plants are particularly effective. Acting as a dehumidifier, these green plants help to clean damp rooms and combat odours and mould residues.
