Houseplants That Naturally Combat Mould and Improve Indoor Air Quality

The saying “it’s not hot, it’s humid!” is definitely one we’ve all heard before. This is often the case when the ‘RealFeel’ temperature feels higher than the actual temperature. During the summer, humidity is considerably high because warm air holds a higher level of water vapour. All soft leaved plants help take moisture out of the air. 

Houseplants not only add aesthetic appeal to your living space but also offer a myriad of health benefits, including purifying the air you breathe. Mould is a common issue in many homes, and it can have adverse effects on your health and the structural integrity of your property. Fortunately, there are several houseplants that can help mitigate mould growth while enhancing your indoor environment. In this blog, we'll explore houseplants that are known for their mould-fighting properties and air-purifying abilities.

Experts indicate that indoor humidity should range between 40-50%. The reason for this is higher humidity rates allow dust mites to thrive in the damp environment. Additionally, high humidity can increase winter mould, mustiness, mildew, and respiratory problems. So how can we eliminate these negative effects and reduce humidity in our homes? Getting a dehumidifier may be an option and have some effects, but houseplants are natural, more effective, and prettier alternative to remove that indoor humidity.
