Indoor plants do more than decorate a room; they shape the air you breathe and the feel of the spaces where you live and work. This book offers a practical guide to choosing, placing, and caring for houseplants with an emphasis on air quality and everyday well-being. You will learn about the science behind plant-related air purification, discover species suited to different light and humidity conditions, and find guidance on maintenance routines that keep plants healthy over time. The book also explores how greenery can influence mood and concentration, helping you create calmer, more balanced interiors. Written and compiled with the assistance of artificial intelligence, this guide draws on established horticultural and environmental research to give you a clear, accessible introduction to the subject, whether you are a beginner or looking to deepen your existing knowledge.
