Polychoron Solutions
Three product lines. One biological platform. From the air your family breathes to the carbon your business captures — built in Bangalore, backed by science.
For your family
Indoor air is often more polluted than outside. Prana Vayu combines living Spirulina biology with active HEPA filtration — reducing CO₂, dust, and particulates so your family breathes easier, thinks clearer, and lives better.
Join the waitlist How it worksAbsorbs CO₂ and releases fresh oxygen continuously — biology doing what it has always done
Captures PM2.5, PM10, dust, pollen, and VOCs — the pollutants your family breathes daily
See exactly what's in your air — and watch it improve
Refill the culture, not a landfill-bound filter. Harvested biomass feeds your plants
Who it's for
Poor indoor air quality affects everyone — but some are more vulnerable. Prana Vayu was designed with them in mind.
Developing lungs are especially sensitive to CO₂, particulates, and VOCs. Cleaner air means better sleep, fewer respiratory issues, and healthier development.
Older adults spend more time indoors and are more susceptible to respiratory conditions. Reducing indoor pollutants directly improves comfort and daily wellbeing.
Dust, pollen, PM2.5, and VOCs are primary indoor triggers. Prana Vayu's active filtration captures these at source — reducing flare-ups over time.
Elevated CO₂ in closed home offices causes brain fog and decision fatigue. Lower CO₂ means sharper thinking and more productive hours.
Bangalore, Mumbai, Delhi — outdoor pollution seeps indoors. Prana Vayu creates a clean zone inside your home regardless of what's outside.
No chemicals, no ozone, no cartridges in landfill. Just biology doing what it has always done — the way nature intended air to be cleaned.
The technology
Prana Vayu is an air purifier which combines active biological CO₂ fixation with mechanical HEPA filtration in one device.
A dense Spirulina culture absorbs CO₂ through photosynthesis and releases fresh oxygen continuously — 24 hours a day, no chemicals, no consumables.
A centrifugal fan draws air through a multi-stage filter — capturing PM2.5, PM10, dust, pollen, and VOCs that the biological system cannot address.
Sensors monitor your indoor air quality continuously. The display shows what's in your air — and the improvement as both systems work together.
Fresh Spirulina culture every 4–6 weeks. Swap in 5 minutes. Harvest the old culture as plant fertiliser. No cartridges, no landfill.
Prana Vayu · Dual system architecture
Why it matters
Indoor CO₂ above 1,000 ppm — common in closed rooms — measurably reduces cognitive performance and decision-making speed. Reducing CO₂ brings levels to ranges where your brain functions at its best.
Elevated CO₂ and particulates disrupt sleep quality — increasing restlessness and reducing deep sleep cycles. Prana Vayu in your bedroom creates conditions for genuinely restorative sleep.
PM2.5 particles are present in virtually every Indian urban home. The HEPA layer captures these before they're inhaled — directly reducing trigger frequency for asthma and allergy sufferers.
Poor indoor air quality is linked to fatigue and low mood — often mistaken for stress or overwork. Cleaner air creates an environment where people feel more energetic and more present.
Running costs
Most air purifiers are designed so you keep buying. Prana Vayu is designed so you don't have to — but you choose how involved you want to be. The biology rewards attention.
For your team's performance
Stuffy offices, high CO₂, invisible dust and pollutants — they cause fatigue, brain fog, and poor decisions. Your team deserves better air. Vayu-X cleans it, sized to your floor, so every person in your office can think and perform at their best.
Get a floor assessmentWho it speaks to
Poor indoor air affects your bottom line — not just your wellness score. Vayu-X speaks to every stakeholder who cares about what your team produces.
Output per employee is your most important operating metric. If your team is thinking at 80% capacity because of the air they breathe, that gap shows up in your revenue. Vayu-X closes it.
Vayu-X costs less per month than one employee's salary — and measurably improves every employee's productive output. That is a return on investment your P&L will reflect.
Fewer sick days, less fatigue, better mood, higher retention. Vayu-X is a visible, tangible investment in your people — the kind that shows up in engagement surveys and exit interviews.
How it works
Vayu-X is not a fixed product. Every installation is sized to your floor area, occupancy, and ventilation — because every workspace is different.
We assess your floor size, occupancy, ventilation, and current CO₂ levels. This determines exactly how many Vayu-X units you need and where to place them.
Before installation we measure your current CO₂ levels, PM2.5, and AQI across the floor. This is your before number — the baseline your ROI calculation is built on.
Units installed, sensors calibrated, real-time dashboard live. Every unit shows live CO₂ and AQI data visible to employees — the display itself signals that the company invests in them.
CO₂ reduction, AQI improvement, system uptime — delivered monthly. The data that proves the investment is working, ready for your board or ESG report.

The ROI case
The productivity math is straightforward. A 20-person team operating at even 10% below cognitive peak because of poor air quality is losing the equivalent of 2 full-time employees worth of output every day.
Typical office CO₂ of 1,000+ ppm measurably impairs decision-making, focus, and creative thinking — in every person on your floor, every working hour.
Vayu-X reduces indoor CO₂ to below 600 ppm — the range where cognitive performance is measurably at its peak. Your team thinks better because the air is better.
Vayu-X delivers measurable cognitive improvement across your entire team — every month, on every floor it runs. Contact us for pricing based on your floor size.
For your business
Phyxis is a living carbon capture system that turns your facility's environmental obligation into a visible statement of leadership — with real-time verified data your ESG report can actually use.
Request a free pilotWho it's for
Your employees, customers, and community are watching. Phyxis gives you something real to show them — not a pledge, not a certificate, but a living system working inside your building every day.
Factories · Plants · Production units
BRSR reporting — mandatory for listed companies. You need auditable carbon data, not estimates.
Tree plantation obligations — slow, unauditable, and weather-dependent. Phyxis replaces them indoors with measurable data.
CSR spend qualification — installations qualify as environmental CSR expenditure under Schedule VII.
Public image — a living carbon capture system inside your facility is a story your customers and community can see working every day.
Campuses · Co-working · Real estate
LEED / IGBC certification — supports green building credits for indoor environmental quality and sustainability innovation.
ESG annual reporting — gives sustainability officers a measurable, visible carbon action that shows up in reports.
Brand differentiation — no other office in your city has a living carbon capture system. It becomes part of your identity and talent story.
Employee pride — people want to work for companies that visibly care. Phyxis is something employees point to.
The comparison
Tree plantation is the current default. Phyxis doesn't replace trees — it replaces the obligation when trees aren't practical.
