This article will guide you through the best air-purifying indoor plants for UK homes, their care requirements, and where you can get them.

The Importance of Air-Purifying Indoor Plants

Before diving into the list of the best air-purifying indoor plants, let’s first understand why it is essential to have these green companions in our homes. Indoor air can be two to five times more polluted than outdoor air, according to the Environmental Protection Agency. Common household items like cleaning products, cosmetics, and even the paint on your walls, can emit volatile organic compounds (VOCs) that pollute your indoor air.

Indoor plants can help combat this issue. Through a process called phytoremediation, plants filter these harmful compounds from the air. They absorb the pollutants through their leaves and roots, then transform them into harmless substances. Some indoor plants also release oxygen and increase humidity, which can be beneficial in dry, air-conditioned environments.

Indoor Plant Care Tips

Caring for indoor plants is relatively straightforward, but it’s important to keep a few key things in mind. Watering requirements vary between plants, but as a rule of thumb, it’s better to underwater than overwater. Most indoor plants prefer bright, indirect light, but some can thrive even in low light conditions.

Use a well-draining potting mix for your indoor plants to prevent water logging, which can lead to root rot. Fertilise your plants once a month during the growing season, but avoid fertilising during the winter as this is usually their dormant period.

Lastly, keep an eye out for common pests such as spider mites, scale, and aphids. If you notice any, treat your plant with a mild insecticide or a mixture of water and mild detergent.
