Creating an outdoor plant box filled with oxygen-boosting plants is a fantastic way to enhance air quality while adding natural beauty to your space. Some of the best plants for this purpose include:

1. Snake Plant (Sansevieria) – Known for its ability to release oxygen at night, making it perfect for round-the-clock air purification.

2. Areca Palm (Dypsis lutescens) – A natural air humidifier that also removes toxins while producing ample oxygen.

3. Spider Plant (Chlorophytum comosum) – Easy to grow and highly effective at filtering pollutants and increasing oxygen levels.

4. Aloe Vera – Besides its healing properties, it releases oxygen and absorbs carbon dioxide efficiently.

5. Peace Lily (Spathiphyllum) – A low-maintenance plant that boosts humidity and oxygen in shaded areas.

For optimal results, combine these plants in your outdoor plant box to create a lush, oxygen-rich environment. Ensure proper sunlight and watering to keep them thriving. Whether on a balcony or patio, these plants will transform your space into a healthier, greener retreat.
