What are the Solutions to Keep Your Lungs Healthy in Delhi NCR Pollution Crisis?

Use quality air purifiers (HEPA Filters) and humidifiers
Vaccinations (Covid-19 and flu)
Frequent hand wash can prevent viral spread
Stay warm and cover up to restrict air hitting your lungs
Always carry your inhaler and follow the treatment plan (for patients)

Why Indoor Air is Now as Dangerous as Outdoors.

The pollution in Delhi is not just about that brown smog you see outside. Ultra-fine PM2.5 particles seep indoors through doors, windows, exhaust fans and even tiny gaps in walls.

Doctors and public health experts repeatedly warn that prolonged exposure increases the risk of asthma attacks, COPD flare-ups, heart attacks, strokes and even cognitive decline.

Sensitive groups including children, seniors, and those with lung or heart disease are hit the hardest, even if they barely step outside. That’s why many doctors in Delhi now put indoor air quality at the same priority level as medicines and diet for high-risk patients.

How Air Purifiers Actually Help Your Lungs.

How to Choose the Best Air Purifier: CADR, Room Size & Filters.

Before you jump into buying, keep this quick checklist:

True HEPA filter (H13 or equivalent): Non-negotiable for asthma and allergies.
CADR (Clean Air Delivery Rate) Higher CADR: faster cleaning. For Delhi, aim for 250–400 m³/h for medium rooms.
Room coverage: Check sq. ft. rating; pick 1.5x your actual room size if pollution is extreme.
Carbon filter: Helps with NO₂, SO₂, VOCs and foul smells from traffic and smoke.
Filter cost and life: Check filter price on Amazon/Flipkart and typical life (6–12 months).
Noise & power use: For bedrooms, low dB and ≤40W is ideal.
No ioniser and ozone: Skip models that generate ozone; they can worsen asthma

Frequently Asked Questions

Do I need a purifier in every room?

Ideally, yes but practically, start with the bedroom where you sleep 7 to 8 hours every night, then add one for the main living area. You can also move a single unit between rooms during the day and night if your layout allows.

Are air cleaners enough to protect me during severe smog days?

No single measure is enough. Combine indoor filtration with N95/N99 masks outdoors, keeping windows closed during peak hours, using exhaust fans wisely, and following your doctor’s advice if you have asthma or heart disease.

What’s the right CADR for my Delhi apartment?

A rough rule is CADR roughly equal to 2–3 times your room volume (in m³) per hour. For a 150 sq. ft. bedroom with a typical ceiling, aim for at least 220–250 m³/h; for a 250–300 sq. ft. hall, 300–400 m³/h or more is better, especially in NCR.

How often should I replace HEPA filters?

Most brands suggest every 6–12 months depending on usage and pollution level. In NCR’s winters, when devices run at higher speeds, filters may saturate faster. Always check the filter indicator and plan for yearly replacement cost while buying.

Are car purifiers or portable travel units worth it for Delhi visits?

If you commute long distances or frequently travel to Delhi for short trips, compact purifiers for hotel rooms and in-car devices can reduce exposure meaningfully, especially for sensitive individuals. They are not a replacement for full-size home units but a good add-on layer of protection.

If you’re in Delhi-NCR, think of these machines like seatbelts for your lungs. You hope you will never “need” them, but when AQI shoots past 300, you will be glad they are already on.
