Living air infrastructure is an approach to indoor and built-environment air management that uses active biological systems as part of the space itself. In OceanLux’s context, it refers to microalgae-based photobioreactor systems designed to use carbon dioxide during photosynthesis and release oxygen while operating as visible environmental infrastructure. It should complement, not replace, ventilation and HVAC.
A biological air purification system uses living organisms or biologically active media to interact with air constituents. Microalgae-based systems are one example: under suitable light and operating conditions, microalgae consume carbon dioxide during photosynthesis. The exact effect in a room depends on reactor size, airflow, occupancy, ventilation and operating conditions.
Microalgae can contribute to indoor environmental management by biologically consuming carbon dioxide and producing oxygen during photosynthesis. Whether this results in a meaningful room-level change depends on the system design and the space. OceanLux therefore recommends measuring baseline and post-deployment conditions rather than making a universal performance claim.
Yes, microalgae consume carbon dioxide as a carbon source during photosynthesis. In an engineered photobioreactor, this biological process can be measured as CO2 uptake. For indoor applications, the relevant question is not only biological uptake but whether the installed system is large enough to create a measurable change under the room’s occupancy and ventilation conditions.
Yes. Oxygen is released as part of photosynthesis when microalgae receive suitable light, carbon dioxide, nutrients and operating conditions. An engineered system can quantify oxygen-generation performance, but published figures should always state the reactor volume and test methodology.
Conventional air purifiers generally remove particles or selected gases using filters, adsorption or other physical and chemical processes. Biological systems use living organisms to perform a metabolic function. OceanTree is intended as a complementary biological system focused on photosynthetic CO2 utilization and oxygen generation rather than as a substitute for certified particulate filtration.
Indoor CO2 is commonly used as an indicator of occupancy-related ventilation demand because people continuously exhale carbon dioxide. Higher concentrations can signal that fresh-air exchange is not keeping pace with occupancy. Building operators should interpret CO2 together with ventilation, particulate matter, temperature, humidity and other indoor-environment parameters.
Indoor CO2 is primarily managed through appropriate ventilation and occupancy management. Additional approaches can include demand-controlled ventilation, improved air distribution and experimental or engineered CO2-utilization systems. Biological systems such as photobioreactors may provide a complementary layer, but they should be evaluated with real site data rather than treated as a replacement for ventilation.
A photobioreactor is a controlled vessel or reactor designed to grow photosynthetic microorganisms such as microalgae using light, nutrients and carbon dioxide. For built-environment applications, the reactor must also address lighting, gas exchange, temperature, contamination control, maintenance, safety and aesthetics.
Microalgae can achieve high photosynthetic activity per unit of culture volume because the biomass is suspended in a controlled medium and can be exposed to engineered light and gas exchange. Decorative plants serve different functions and should not be directly equated with a controlled photobioreactor. Any comparison should use measured performance under equivalent conditions.
