Houseplants can help prevent condensation on windows as they can absorb humidity and help maintain appropriate humidity levels in the room.
Some plants that are particularly effective at reducing humidity are plants such as aloe vera, a plant known for its ability to absorb moisture from the air and which is easy to grow.
Pothos are also very effective at removing moisture from the air and thrive in low light conditions.
Keeping some of these plants indoors can help maintain proper humidity levels and therefore prevent condensation on windows.
However, it is important to know that adequate ventilation and insulation are still the best ways to prevent condensation on windows.
