Biotechnology for indoor air
Breathe More Oxygen. Live Better Every Day.
Pneuma Tree by Witwake is a living microalgae system engineered for modern interiors. It is designed to support cleaner, fresher, oxygen-enriched indoor air — quietly, continuously and sustainably.
Scientific innovation
Nature's oldest oxygen engine, precisely engineered
Microalgae have oxygenated our planet for billions of years. Witwake’s research team stabilised that biology inside a controlled, sensor-driven column so it can perform reliably inside a living room, a boardroom or a hospital corridor.
Controlled biology
Light spectrum, temperature, pH and nutrient dosing are held inside a narrow band so the culture stays healthy and productive.
Engineered airflow
A low-noise circulation path draws room air through filtration and across the photosynthetic column before returning it to the space.
Measured, not claimed
Onboard sensors log particulate load, humidity, CO₂ and culture health so performance is transparent and auditable.
About Pneuma Tree
A biotechnology company built around one question: what should indoor air feel like?
Witwake began as a small applied-biology group studying algal productivity. Pneuma Tree is the product of that work — a system that brings a functioning micro-ecosystem indoors without asking anyone to change how they live.
Pneuma Tree is designed to support cleaner, more comfortable indoor air. It complements building ventilation and is not a medical device.

Scientific innovation
Most of life happens indoors. Air quality should keep up.
Sealed buildings, synthetic materials, cooking, traffic and dense occupancy all shape what we breathe inside. Cleaner, fresher air can contribute to a more comfortable and pleasant indoor environment.
Sealed modern buildings
Energy-efficient envelopes reduce natural air exchange, so indoor pollutants can accumulate through the day.
Everyday sources
Cooking, cleaning agents, furnishings, printers and outdoor traffic all contribute to the indoor particulate and VOC load.
Dense occupancy
Meeting rooms, classrooms and wards see CO₂ levels climb quickly, which many people experience as stuffiness or fatigue.
Long exposure hours
We spend the overwhelming majority of our day inside, so small differences in air quality compound over time.
Product highlights
One system. Three considered forms.
Every Pneuma Tree shares the same biological core and the same quiet engineering — the difference is scale and installation.

Health & wellbeing
Designed to support how you feel indoors
Individual experience varies. These are the outcomes our design targets, described in the careful language they deserve.
Easier breathing
Designed to support cleaner air with a lower particulate load in the room.
Everyday alertness
Fresher, better-ventilated air can contribute to a more comfortable environment for focused work.
Calmer evenings
A quiet night mode and softer air movement help create a restful bedroom atmosphere.
Lower fatigue from stuffiness
Reducing that closed-room feeling can make long indoor hours more pleasant.
How it works
Four quiet stages, running continuously
Air intake
Room air is drawn in through a low-noise inlet at floor level, where turnover is highest.
Multi-stage filtration
Pre-filter, HEPA-grade media and activated carbon capture dust, particulates and common odour compounds.
Photosynthetic exchange
Filtered air passes across the illuminated microalgae column, where CO₂ is consumed and oxygen is released
Fresh return
Conditioned air re-enters the room through a diffused outlet while sensors log the cycle.
Applications
Built for the spaces people spend their lives in
Homes & apartments
Living rooms, bedrooms and home offices where families spend most of their indoor hours.
Offices & coworking
Meeting rooms and open floors where occupancy density peaks through the working day.
Hospitals & clinics
Waiting areas, consultation rooms and corridors, deployed alongside existing clinical air systems.
Schools & universities
Classrooms, libraries and study halls where students sit for long, continuous sessions.

Pneuma Tree – Frequently Asked Questions
Questions people ask first
Pneuma Tree is a living biotechnology unit. Inside a sealed, engineered column, cultures of microalgae photosynthesise continuously while a quiet airflow system circulates room air through the system. It is designed to support fresher, oxygen-enriched indoor air as part of a well-ventilated space.
Conventional purifiers only capture particles on a filter. Pneuma Tree combines multi-stage filtration with a living photosynthetic culture, so the unit is designed both to reduce airborne particulates and to contribute oxygen back into the room.
No. The culture is fed by a nutrient cartridge that is typically replaced every few months, and the water column is topped up periodically. The onboard sensors and app indicate exactly when service is due.
Yes. The culture is fully enclosed behind a sealed, shatter-resistant column, and the unit operates at low voltage with no ozone-generating components.
