Air quality is an important factor for a healthy and safe living environment. Poor air quality can lead to various health problems including respiratory issues, allergies, and even cancer. To describe the quality of air, we can use a wide range of synonyms such as air purity, air cleanliness, air hygiene, air freshness, air clarity, air safety, and air healthiness. More colloquially, we can also use phrases like fresh air, clean air, breathable air, or pure air. Monitoring the quality of air is essential for taking preventive measures to improve it. With increasing environmental concerns, every individual should strive to keep the air quality at a high standard in their surroundings.
