Indoor plants not only add beauty and tranquility to your living spaces but also play a crucial role in purifying the air. Many plants absorb toxins, increase humidity, and release oxygen, making your home healthier and more comfortable. Here’s a guide to the best plants for improving indoor air quality and how to care for them.

1. Why Indoor Plants Improve Air Quality

Filters Harmful Pollutants

Plants remove common indoor toxins like benzene, formaldehyde, and carbon monoxide from the air.

Boosts Oxygen Levels

Through photosynthesis, plants increase oxygen, improving breathing and energy levels.

Adds Humidity

Plants release moisture into the air, reducing dryness and improving respiratory health.

Reduces Stress and Enhances Mood

Studies show that being around plants lowers stress and promotes mental well-being.
