Excessive moisture within a house can arise due to capillary action, infiltration, or the phenomenon of condensation. The latter is the only aspect over which home dwellers can quickly act by modifying certain habits. Some plants are especially effective in combating this moisture. These plants absorb the humidity and prevent mold formation.
Humidity can manifest as fog on windows or damp walls. Besides wall damage, a very humid environment can lead to mold growth. However, certain indoor plants can reduce condensation and serve as a treatment against humidity.
Why Does Condensation Occur in Homes?
When the water vapor present in the surrounding air comes into contact with cold surfaces, condensation forms, turning the vapor into water. This results in fine droplets appearing on these surfaces. Condensation issues can arise in both new and old construction materials. Human activities, such as taking a hot shower, breathing, sweating, or cooking food in the kitchen, can raise the humidity level. This humidity level in the air is known as hygrometry. Consequently, water vapor ends up condensing, leading to moisture problems within living spaces.
What Factors Encourage Condensation Issues?
Several elements can promote the occurrence of condensation. Poor home ventilation, inadequate ventilation, a fault in the ventilation system, improper insulation, or a transition from warm to cold air are potential causes contributing to a house’s condensation problems.
Understanding the Impact of Condensation and How Indoor Plants Can Help
Consequences of Condensation Issues:
Condensation, resulting from the cooling of warm and moist air, can manifest as moisture marks on walls, ceilings, and mirrors. The repercussions? Mold spots appear on walls, paint begins to peel, and wallpaper loosens. Beyond its unsightly appearance, mold can pose health risks for the inhabitants. Indeed, these microscopic fungi multiply and can release spores and mycotoxins. These toxic substances can irritate respiratory pathways, leading to asthma, rhinitis, or bronchitis.
Indoor Plants for Air Dehumidification:
To regulate the humidity level in the air and combat mold, certain indoor plants are particularly effective. Operating like a dehumidifier, these green plants help sanitize damp rooms and fight against mold odors and stains.
1. Cacti:

Cacti can absorb ambient moisture and combat the presence of humidity in homes. These indoor plants are easy to care for and only need occasional watering.
2. Boston Fern:

The Boston fern is a tropical plant that aids in eliminating airborne moisture. For its optimal growth, its soil should remain moist. Place this plant in a bright location but shielded from direct sunlight.
3. Orchids:

Widely loved, orchids have roots capable of capturing ambient humidity. Position your plant in a well-lit room away from direct sunlight and moisten it once a week.
4. Tillandsia:

Also known as “air plant”, tillandsia traps moisture in its leaves. Place your plant in a bright room protected from sunlight and use lime-free water once a week to moisten it.
5. Spathiphyllum:

Spathiphyllum is a tropical plant that reduces a home’s humidity level with its leaves. To allow it to thrive, place the plant in a well-lit location without exposing it directly to sunlight. Regularly water it for maintenance.
