Dr Shreya Dubey on Instagram: "Can’t buy an air purifier right now? Start here. Healthy air isn’t just about machines — it’s about mindful living. Here are small, powerful changes that make a real difference 👇 ✨ Open windows when AQI allows — fresh air still wins. 🚫 Cut smoke, incense, and harsh paints — control the source. 💧 Balance humidity — avoid mould, clean fans & filters. 🌱 Add green — plants, charcoal bags, even DIY fan filters help more than you think. 💨 Make your home breathe agai
