From lab to ceiling fan
The Science Behind Vaayuraksh
Every Vaayuraksh filter is built from independently analysed materials and engineered to clean the air in real Indian homes — not laboratory chambers.
Air that's as clean as the science behind it
India's air carries challenges no home was ever designed for — PM2.5 from traffic, smoke from cooking oil and incense, monsoon mould spores, and a year-round dust load that turns every fan blade grey within weeks.
We built Vaayuraksh to turn the ceiling fan you already own into the most consistently used air filter in your home. And to prove it works, we test the materials and the performance of our filters with two independent, government-accredited laboratories.
Air Quality & Your Health
The contaminants floating through an Indian home aren't abstract. They show up as irritation, lethargy, and symptoms that families often blame on “the season” — when the real culprit is the air itself.
- Eye, nose and throat irritation from dust and smoke
- Headaches and brain fog after long indoor hours
- Disturbed sleep and morning fatigue
- Sneezing, runny nose and seasonal allergy flare-ups
- Coughing and chest tightness from cooking and agarbatti smoke
- Worsening of asthma and respiratory symptoms
- Persistent kitchen and pet odours that fans alone can't clear
What's Inside Every Vaayuraksh Filter
An independent ISO-accredited laboratory in Shenzhen broke our filter down to its molecules. The result is a transparent, four-component composition — no mystery coatings, no hidden binders. Just an activated-carbon-loaded fibre engineered to capture what an Indian home throws at it.
-
39.1% · Activated Carbon CAS 1333-86-4
The dark, porous core of the filter. Adsorbs odours, kitchen smoke, agarbatti and dhoop residue, and volatile organic compounds (VOCs) released by paints, cleaners, and synthetic fabrics.
-
31.8% · Polyethylene Terephthalate (PET) CAS 25038-59-9
The non-woven fibre matrix that gives the filter its structure. Captures airborne dust, pollen, and PM2.5 / PM10 particulate as your ceiling fan circulates the air through it.
-
22.7% · Styrene-Acrylic Copolymer Binder
A medical-grade binder that permanently locks activated carbon onto the PET matrix, so the filter never sheds carbon dust onto your furniture or into the air below.
-
6.4% · Trace Components Colouring & finishing
Inert finishing agents that give the filter its uniform appearance and ensure colour-fastness through the fan's operating life.
Independently Verified: VOC & Odour Removal
An independent test by the Guangdong Detection Center of Microbiology measured how much formaldehyde and benzene a single Vaayuraksh filter could pull out of a sealed test chamber over 24 hours. These are the verified results.
Start: 1.16 mg/m³ After 24 h: 0.147 mg/m³
Start: 1.27 mg/m³ After 24 h: 0.042 mg/m³
Concentration in 1.5 m³ chamber after 24 hours
Formaldehyde
Benzene
All values in mg/m³ · bar heights scaled to the highest measurement (1.27 mg/m³)
Key finding — A single Vaayuraksh filter, sealed in a 1.5 m³ chamber for 24 hours, removed 87.3% of airborne formaldehyde and 96.7% of airborne benzene — two of the most common indoor air pollutants in Indian homes.
Tested under QB/T 2761-2006, China's national standard for evaluating formaldehyde and VOC removal performance of air-purifying textile materials. Verification code 95862041.

Our filter is analysed under five international test standards using seven laboratory-grade instruments, by two independent Chinese-government-accredited testing bodies.

What We're Testing Next
Beyond the formaldehyde and benzene results above, our next round of independent testing covers particulate matter and airborne allergens. Each report will be added here, with the full PDF, as soon as it's signed off by the lab.
PM2.5 & PM10 particulate capture
Independent aerosol-chamber testing for ultra-fine particulate matter, road dust, and Diwali-season smoke.
Test commissioned · results expected Q1 2026
Allergen capture efficiency
Pollen, dust mite fragments, pet dander and other common Indian household allergens, tested under aerosol chamber conditions.
Test commissioned · results expected Q1 2026
Microplastic fibre capture
Airborne synthetic fibres from clothing, upholstery, and household textiles in the 1–5 µm range.
Test commissioned · results expected Q1 2026
Turn your ceiling fan into an air purifier
One peel-and-stick filter per blade. No installation, no electricity, no replacement parts — just cleaner air every time the fan spins.
