The current levels of air pollution, especially in urban areas, are high. Respiratory illnesses like asthma, sinuses, and breathing difficulties have increased due to air pollutants.

Besides allowing fresh air to circulate through our homes by keeping our windows open, indoor plants can also purify the air by supplying clean oxygen.

House plants with many large leaves are the best as they produce the most oxygen during photosynthesis.

Photosynthesis is a molecular process where plants use water, carbon dioxide, and light to produce oxygen. Large house plants require sufficient sunlight to produce oxygen.

Keep In Mind – It’s essential to keep the plants where they can acquire the most light and air. Above all, select a house plant that will thrive in the amount of light available in your home.
