Introduction

Air pollution doesn’t just stay outside, it enters our homes and in cities like Chennai, Bangalore, Delhi, and Mumbai and also industrial cities, with rising PM2.5 levels, traffic emissions, and household chemicals, checking indoor air quality (IAQ) is becoming as important as knowing the outdoor Air Quality Index (AQI).

This guide by SMS Labs will help you understand how to check air quality in your home, what affects it and when professional air testing might be needed.

Why Indoor Air Quality Matters in Indian Homes

According to the Central Pollution Control Board (CPCB), indoor air in Indian homes can be 2–5 times more polluted than outdoor air — especially during winters or festive seasons when ventilation reduces and incense, cooking smoke or mosquito coils increase.

Common indoor pollutants include:

• Particulate Matter (PM2.5 & PM10): From dust, cooking, candles and traffic infiltration
• Volatile Organic Compounds (VOCs): From paints, perfumes, cleaning sprays
• Carbon monoxide (CO): From gas stoves, generators
• Formaldehyde: From new furniture, plywood, and adhesives

These pollutants can trigger asthma, allergies, fatigue and even long-term respiratory illnesses.

Step-by-Step: How to Check Air Quality in Your Home (India)

1️⃣ Check Outdoor AQI First

Start by checking your local Air Quality Index using:

• SAFAR India (safar.tropmet.res.in) – by the Indian Institute of Tropical Meteorology
• AQI India – real-time air quality data by city
  If outdoor AQI is poor, close windows during peak pollution hours.

2️⃣ Look for Indoor Pollution Signs

Without instruments, you can spot early warning signs:

• Musty smell, visible mould on walls or furniture
• Frequent sneezing, watery eyes or headaches at home
• Excessive dust accumulation

Sticky residue near kitchen or incense areas
These indicate poor ventilation or hidden pollutants.

3️⃣ Use a Portable Air Quality Monitor

Today, several affordable air quality monitors are available online in India (Mi, Kaiterra, Qubo, Airthings, etc.) that measure PM2.5, CO₂, VOCs, temperature and humidity.

• Place the monitor in your living room and bedroom for 24–48 hours
• Avoid placing near windows or fans for accurate readings
• Note levels of PM2.5 (<35 µg/m³ is good) and CO₂ (<800 ppm is ideal)

You can also use mobile devices like Plume Labs’ Air Report App to track both indoor and outdoor conditions.

4️⃣ DIY Test Kits or Professional Lab Testing

If you suspect specific issues — for example, formaldehyde from new furniture or radon in basements — a consumer device may not be enough.
You can:

• Use DIY air test kits (available on Amazon India) for quick checks.
• Or get professional indoor air testing done by SMS Labs for detailed analysis of particulate matter, gases and microbial content.

5️⃣ Improve and Maintain Good Air Quality

Once you know your air quality status:

• Ventilate smartly: Open windows in early morning or late evening when outdoor AQI is lower.
• Use air purifiers: Choose models with HEPA + activated carbon filters suited for Indian dust and pollen.
• Keep house plants: Aloe Vera, Spider Plant, and Areca Palm naturally help reduce VOCs.
• Switch to cleaner habits: Avoid incense sticks or use natural alternatives and prefer low-VOC paints and cleaning products.
