How Do These Plants Purify the Air?
These plants work through a natural process called phytoremediation, where they absorb toxins through their leaves and roots. Harmful chemicals are then broken down and neutralized by microorganisms in the soil. Plants also increase indoor oxygen levels through photosynthesis, making the air fresher to breathe.
Creating Your Air-Purifying Indoor Garden
To maximize the benefits of these plants:
- Place a variety of air-purifying plants in different rooms.
- Ensure adequate light and water for each plant’s specific needs.
- Avoid overcrowding; plants need good airflow to thrive.
By adding these natural air purifiers to your home, you’ll create a greener, healthier, and more vibrant indoor space.
