Delhi NCR’s air quality context
Delhi NCR’s annual PM2.5 average is 80-110 µg/m³ — roughly 6-7× the WHO guideline and among the worst of any global metropolitan area. The 10-year IQAir World Air Quality Report has consistently placed Delhi in the top 5 most polluted capital cities.
Key pollution sources in South Delhi:
- Stubble burning in Punjab and Haryana (Oct-Nov peak, contributes 25-40% of Delhi pollution during October-November)
- Vehicle emissions — Delhi has one of the highest vehicle densities per km² in India
- Industrial belt — northwest of Delhi (Bawana, Narela) contributes particulates under specific wind conditions
- Construction dust — continuous across South Delhi
- Diwali fireworks — a two-week AQI 400-600 spike annually
A fresh air system is designed to work during the worst of these episodes. Our peak-AQI operating mode (6 V) increases airflow to keep indoor PM2.5 under 35 µg/m³ even with outdoor AQI at 500+.
Why South Delhi homes install aqi0
-
Independent homes and low-rise apartments — the classic South Delhi stock. Core-cut installs through brick walls are straightforward. Ground-floor and second-floor installs are our most common.
-
Heritage + modern retrofits. We’ve installed in 1960s-era bungalows and 2020s apartment conversions. The system retrofits into existing envelopes without visible interior changes.
-
Delhi pollution is a year-round concern. Unlike Gurugram where Cyber City commuting creates a midday dip, South Delhi residents are exposed 24/7. Continuous ventilation makes more difference here than occasional “clean-up” by room purifiers.

Air quality in South Delhi, measured
Our Delhi customers’ indoor PM2.5 pattern (across our installs):
| Outdoor AQI | Indoor PM2.5 (with aqi0) |
|---|---|
| 100-150 (Apr-Sep typical) | < 10 µg/m³ |
| 200-300 (Oct-Nov build-up) | 15-25 µg/m³ |
| 300-450 (Nov-Jan peak) | 20-35 µg/m³ |
| 450-600 (Diwali week) | 30-45 µg/m³ |
At outdoor AQI 500, your indoor air is typically under AQI 50. That’s the gap the system delivers — a 10× reduction sustained through the worst of Delhi’s pollution calendar.
Pricing for Delhi installs
Standard pricing applies — ₹70,000 + GST (₹82,600 all-in). Installation included. Delhi installs have the same site-visit and install cadence as Gurugram (site visit within 48-72 hours; install within 5-7 days).
FAQ for Delhi residents
Will a fresh air system help during stubble burning season?
This is when it helps most. Outdoor AQI during late October and November regularly crosses 400 and occasionally 600. Our system ramps to peak operating voltage (6 V) during these periods, typically keeping indoor PM2.5 at AQI 50-80 — a 10× reduction.
I live in a heritage bungalow — can you install without damaging architecture?
Yes. We’ve worked in heritage properties in Defence Colony, Friends Colony, and Jor Bagh. Install locations are often utility walls or back-of-house areas invisible from living spaces. The exterior grille is discrete and can be painted to match the wall.
Do you handle society approvals?
We provide installation drawings and specs for RWA approval. The approval process itself is the customer’s responsibility, but our drawings have been accepted in ~100% of Delhi societies we’ve worked with.
I live on the 10th floor — does the install work?
Absolutely. Higher-floor installs tend to have cleaner intake air (especially above the street-level dust layer). The installation method is the same; site visit will confirm window/wall access.
