Industries We Serve

Every Space Has Its
Own Air Problem

We don't apply generic solutions. We understand the specific challenges each environment faces — and design accordingly.

Office
🏢 Corporate Offices

High CO₂ from people in enclosed spaces causes measurable drops in focus and productivity. We measure your actual levels and design ventilation + purification.

Hospital
🏥 Hospitals & Clinics

Healthcare environments need pathogen reduction, particulate filtration and VOC control from disinfectants. Compromised air is a patient safety risk.

School
🏫 Schools & Universities

Children breathe more air per kg of body weight. High CO₂ in classrooms reduces learning capacity. We install child-safe, low-noise solutions.

Hotel
🏨 Hotels & Hospitality

Guest experience is directly affected by air quality. Stuffy rooms hurt reviews. We help hotels maintain consistently fresh air — a premium amenity.

Factory
🏭 Factories & Warehouses

Industrial spaces have severe IAQ issues — chemical VOCs, heavy PM10 dust and poor ventilation. We design robust filtration for compliance.

Gym
💪 Gyms & Wellness

During exercise, people breathe 10–20× more air. We design high-throughput filtration for high-occupancy fitness spaces where CO₂ spikes fast.

Not Sure?

Just Book the Audit

The devices don't care what industry you're in. The data tells us the problem. Start there.

Why Zero Particulate

The Only IAQ Company
That Measures First

Anyone can sell you a purifier. Very few will tell you what your air actually contains before recommending one.

What the Data Says About Indian Air

These are real studies, real organisations, and real measured outcomes from across India — not our own work. We share them because the science speaks clearly: indoor air quality is a serious, solvable problem.

Multi-Building Study · Delhi

IIT Delhi + Kaiterra — 37 Buildings, Winter 2019–20

IIT Delhi's Centre of Excellence for Research on Clean Air (CERCA), in association with the Society for Indoor Environment and Kaiterra, monitored 37 buildings across Delhi — offices, schools, hospitals, restaurants, and malls. PM10, PM2.5, CO₂, and TVOC were tracked over 24-hour periods. Indoor pollutant levels were found to be 2–5× above CPCB permissible limits and 10–15× above WHO 24-hour averages across all building types. Schools had the worst PM2.5 indoor/outdoor ratios. Offices recorded CO₂ consistently above 1,300 ppm due to poor ventilation and ductless AC systems.

CO₂: 1,300–1,500 ppm avg in offices WHO limit: 1,000 ppm

Corporate Office · Gurgaon

Zomato HQ — 100,000 sq.ft. Office, Post-Renovation VOC Crisis

After moving into a newly renovated 100,000 sq.ft. office in Gurgaon, Zomato faced elevated VOC and formaldehyde levels from fresh paint, carpets, and remodelling — combined with Delhi-NCR's high ambient PM2.5. Staff were experiencing headaches and drowsiness. Smart Air installed 91 purifiers across all floors without infrastructure changes. After 21 days of monitoring across 6 audits, PM2.5 dropped by 87%, formaldehyde by 82%, and VOCs by 93% on average.

Ford India — Multi-Floor Office Air Purification

Ford India's Delhi office team was concerned about staff exposure to PM2.5 and VOCs. Rather than modifying the central HVAC — which would have required custom design, structural changes, and months of lead time — they installed 14 Blast and Blast Mini portable purifiers with H13 HEPA and activated carbon filters. Post-installation testing confirmed PM2.5 reduced by 95% and VOCs by 68% on average across the entire office, with zero disruption to daily operations.

Research Study · Pan-India

30 Air-Conditioned Indian Offices — Comprehensive IEQ Audit (2024)

A peer-reviewed field study published in Energy & Buildings evaluated indoor environmental quality across 30 air-conditioned offices in India, measuring 17 parameters including CO₂, PM2.5, TVOC, and NO₂. The study found a prevalence of sub-standard indoor environments — the dominant concerns being high CO₂, TVOC, PM and NO₂. The research concluded that most Indian offices fail to meet both national (CPCB/NBC) and international (ASHRAE/WHO) IAQ standards.

CO₂ Reduction via Air Purification in Indian Office Buildings

A study published in PMC evaluated an air purification system installed in Indian office buildings specifically targeting CO₂ accumulation — a common problem in sealed, AC-heavy offices. The system reduced indoor CO₂ by over 40%. As a bonus, required fresh air intake was cut by more than 50%, reducing cooling load and energy costs — making the intervention both healthier and cheaper to operate long-term.

The Pattern Is Clear

Your Office Is Likely No Different

Every study above found the same thing — sealed Indian commercial spaces consistently exceed safe pollutant limits. An audit tells you your exact numbers in 30 minutes.

Understand Your Air

Know What You Breathe

Indoor air is 2–5× more polluted than outdoor air. Here's what we measure and why it matters.

🔴 Particulate Matter — PM2.5

Fine particles smaller than 2.5 micrometers — invisible to the naked eye. They bypass your nose and throat entirely, penetrate deep into lung tissue, and enter your bloodstream directly. Long-term exposure is linked to heart disease, stroke, lung cancer, and premature death.

Indoor sources: Cooking smoke, incense, candles, printers, outdoor air infiltration through windows and HVAC systems.

WHO SAFE LIMIT 15 µg/m³ annual avg · 45 µg/m³ 24hr avg

⚠ Typical Indian office: 40–120 µg/m³ — up to 8× over limit

🧪 Volatile Organic Compounds — VOCs

VOCs are chemical gases released from hundreds of everyday materials — paints, adhesives, furniture, carpets, cleaning products, air fresheners, and even photocopiers. They accumulate silently in enclosed spaces and are a major driver of "Sick Building Syndrome."

Health effects: Eye and throat irritation, headaches, dizziness, liver and kidney damage with chronic exposure. Several VOCs (benzene, formaldehyde) are classified human carcinogens.

WHO SAFE LIMIT Total VOC < 300 µg/m³ · Benzene < 1.7 µg/m³

⚠ New offices and renovated spaces routinely exceed 1000 µg/m³ in the first 6 months

🟡 Carbon Dioxide — CO₂

CO₂ is exhaled by every person in the room. In sealed or poorly ventilated spaces, it builds rapidly. Unlike other pollutants, CO₂ is a direct proxy for ventilation quality — high CO₂ means stale air, low oxygen replenishment, and a cocktail of other pollutants building up alongside it.

Cognitive impact: Studies show decision-making ability drops by 15% at 1000 ppm, 50% at 2500 ppm. Your "afternoon slump" is often CO₂ poisoning — not tiredness.

WHO / ASHRAE SAFE LIMIT < 1000 ppm · Outdoor baseline: ~420 ppm

⚠ Measured 1800–2800 ppm in most Ahmedabad offices during peak hours

WHO Safe Limits — Quick Reference

Parameter WHO Limit Common Indoor Health Risk
PM2.5 15 µg/m³ 40–120 µg/m³ Cardiovascular, lung cancer
TVOCs 300 µg/m³ 300–2000 µg/m³ Sick building syndrome, cancer
CO₂ 1000 ppm 800–2800 ppm Drowsiness, cognitive decline
