One building at a time — professional-grade measurement, WHO-benchmarked data, and precision solutions designed for your space.
Every engagement starts with measurement. No guessing. No unnecessary upselling. Data first, always.
We visit and measure PM2.5, PM10, CO₂, Formaldehyde, Temperature and Humidity. You get a WHO-benchmarked printed report the same day.
Based on your data, we design a space-specific fix. A hospital needs different treatment than an office. One size never fits all.
Multi-brand supply — always the best fit. Professional installation and optional AMC to keep your air clean year-round.
"You can't fix what you can't measure.
We make your air visible."
From first measurement to annual maintenance. One team, one point of contact, zero guesswork.
We visit your site and measure all key parameters — PM2.5, PM10, CO₂, Formaldehyde, Temperature, Humidity. You receive a detailed, WHO-benchmarked printed report the same day.
Different spaces have fundamentally different problems. A hospital needs pathogen control. An office needs CO₂ management. We design the precise solution from your audit data.
We supply from multiple manufacturers — always recommending what performs best for your specific space. Brand-agnostic. Professional installation with post-install verification.
Scheduled servicing, filter replacements, periodic re-audits and 24hr support. You get proof your air is still clean — not just hope that it is.
"Clean air isn't a device. It's a system — designed, installed, and maintained with precision."
We don't apply generic solutions. We understand the specific challenges each environment faces — and design accordingly.
High CO₂ from people in enclosed spaces causes measurable drops in focus and productivity. We measure your actual levels and design ventilation + purification.
Healthcare environments need pathogen reduction, particulate filtration and VOC control from disinfectants. Compromised air is a patient safety risk.
Children breathe more air per kg of body weight. High CO₂ in classrooms reduces learning capacity. We install child-safe, low-noise solutions.
Guest experience is directly affected by air quality. Stuffy rooms hurt reviews. We help hotels maintain consistently fresh air — a premium amenity.
Industrial spaces have severe IAQ issues — chemical VOCs, heavy PM10 dust and poor ventilation. We design robust filtration for compliance.
During exercise, people breathe 10–20× more air. We design high-throughput filtration for high-occupancy fitness spaces where CO₂ spikes fast.
The devices don't care what industry you're in. The data tells us the problem. Start there.
Anyone can sell you a purifier. Very few will tell you what your air actually contains before recommending one.
We work with multiple manufacturers. We recommend what's right for your space — not what gives us the best margin.
We never recommend without measuring first. Every client gets device-measured data and a WHO report before any purchase decision.
Every audit produces a branded A4 report. Keep it for records, share with employees, present to regulators.
Audit → design → supply → install → maintain. One team, one contact. No coordinating multiple vendors.
Ahmedabad-based team. Same-week installation. Fast support. No waiting for technicians from another city.
No commitment required. We visit, measure and give you a printed report. Then you decide. Most clients are surprised by what the data shows.
Every project starts with measurement. Here's what the data showed — and what changed after our intervention.
Employees reported headaches and drowsiness every afternoon. Our audit revealed CO₂ levels exceeding 1800 ppm (WHO safe limit: 1000 ppm) and PM2.5 at 85 µg/m³ — 3.4× above safe levels. We installed a zoned purification + fresh air intake system.
Hospital management wanted to reduce airborne pathogen risk in ICU. Audit found PM2.5 at 72 µg/m³ and formaldehyde from cleaning agents at 0.15 mg/m³ (WHO limit: 0.1). We deployed medical-grade HEPA + activated carbon filtration.
Parents complained about children falling sick frequently. Our audit measured PM10 at 180 µg/m³ near the playground entrance and CO₂ at 2200 ppm in closed classrooms. Installed child-safe ceiling purifiers with low-noise operation.
Indoor air is 2–5× more polluted than outdoor air. Here's what we measure and why it matters.
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.
⚠ Typical Indian office: 40–120 µg/m³ — up to 8× over limit
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.
⚠ New offices and renovated spaces routinely exceed 1000 µg/m³ in the first 6 months
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.
⚠ Measured 1800–2800 ppm in most Ahmedabad offices during peak hours
| 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 |
A 30-minute audit tells you exactly what you're breathing. No guesswork. No commitment.
Industry insights, research findings, and updates from Zero Particulate.
The World Health Organization's 2024 revision tightened PM2.5 annual limits to 5 µg/m³. Indian cities average 25–60 µg/m³ outdoors — making indoor air quality management critical for health.
After installing our medical-grade HEPA filtration system, post-surgical infection rates dropped measurably. The key insight: formaldehyde from cleaning agents was the hidden culprit.
New GPCB guidelines now require annual IAQ audits for commercial spaces above 500 sq.ft. with more than 20 occupants. Here's how to stay compliant.
