How We Work

Diagnosis Before Solution

Every engagement starts with measurement. No guessing. No unnecessary upselling. Data first, always.

01 / 03
🔬
IAQ Audit

We visit and measure PM2.5, PM10, CO₂, Formaldehyde, Temperature and Humidity. You get a WHO-benchmarked printed report the same day.

02 / 03
📐
Custom Solution

Based on your data, we design a space-specific fix. A hospital needs different treatment than an office. One size never fits all.

03 / 03
⚙️
Install & Maintain

Multi-brand supply — always the best fit. Professional installation and optional AMC to keep your air clean year-round.

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.

Proven Results

Real Sites, Real Transformations

Every project starts with measurement. Here's what the data showed — and what changed after our intervention.

Corporate Office · Ahmedabad

50-Person Tech Office — Chronic Afternoon Fatigue

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.

Before: AQI 168 After: AQI 42

Hospital · Vadodara

ICU Wing — Post-Surgical Infection Concerns

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.

Before: AQI 155 After: AQI 28

School · Surat

Primary School — Children's Respiratory Health

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.

Before: AQI 192 After: AQI 38

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.

🔴 What is PM2.5?
Fine particulate matter smaller than 2.5 micrometers. These particles penetrate deep into your lungs and enter your bloodstream. Sources indoors: cooking, candles, outdoor infiltration, printers. WHO safe limit: 15 µg/m³ (annual average).
🟠 What is PM10?
Coarser particles up to 10 micrometers. Includes dust, pollen, mold spores. While they don't penetrate as deeply as PM2.5, they irritate airways and trigger allergies. WHO safe limit: 45 µg/m³ (annual average).
🟡 What is CO₂?
Carbon dioxide — we exhale it. In poorly ventilated rooms with many people, CO₂ builds up fast. Above 1000 ppm, you get drowsy and lose focus. Above 2000 ppm, headaches and nausea begin. Outdoor baseline: ~420 ppm.
🟣 What is Formaldehyde (HCHO)?
A volatile organic compound (VOC) emitted by furniture, paint, cleaning products, and new carpets. Classified as a human carcinogen by WHO. Safe limit: 0.1 mg/m³. New offices and recently renovated spaces are highest risk.
🌡️ Why does Temperature matter?
ASHRAE recommends 23–26°C for optimal productivity. Below 20°C, manual dexterity drops. Above 28°C, cognitive performance degrades significantly. Temperature also affects pollutant off-gassing rates.
💧 Why does Humidity matter?
Ideal range: 40–60% RH. Below 30%, you get dry eyes, skin irritation, and static. Above 60%, mold grows exponentially. Humidity also affects how long airborne viruses remain infectious.

WHO Safe Limits — Quick Reference

Parameter WHO Limit Common Indoor Health Risk
PM2.5 15 µg/m³ 25–80 µg/m³ Cardiovascular, respiratory
PM10 45 µg/m³ 50–200 µg/m³ Allergies, asthma triggers
CO₂ 1000 ppm 600–2500 ppm Drowsiness, poor cognition
HCHO 0.1 mg/m³ 0.02–0.5 mg/m³ Carcinogen, eye irritation
Temperature 23–26°C 18–32°C Productivity loss
Humidity 40–60% RH 20–80% RH Mold, virus viability
