Naava and Biofiltration – Natural Indoor Air for Everyone

NASA’s research results + Naava’s biofiltration technology = our smart Naava green wall

NASA’s findings in space reveal hidden features of plants on Earth

In 1989, NASA studied how air could be cleaned naturally and effectively in space stations. It’s obvious that we have favorable conditions for life on Earth, but when heading off to space, NASA faced big obstacles in re-creating surroundings where a man could live and survive.

Green plants are well known for their air purifying efficiency and they play a vital role in our effectively working ecosystem. What the NASA study surprisingly revealed was the fact that 98% of air purification takes place in plants’ roots, not in the leaves, contrary to popular belief.

The air purification efficiency of plants isn’t in their leaves, but in their roots and the microbiome there instead.

Naava plants: heartleaf philodendron (Philodendron scandens)

Based on this finding, the founders of Naava, Aki Soudunsaari, a teacher who got sick due to poor indoor air quality, and Niko Järvinen, who studied environmental science at the time, decided to find out how the result could be utilized and how air could be circulated through the plants’ roots more efficiently to accelerate the air purification efficiency. So, they started to build a natural air purifier that uses plants and air circulation and works as a biofilter, later named the Naava green wall.

Biofiltration – pure air with natural means

Biofiltration is a pollution control technique where a bioreactor containing living material is used to capture and biologically degrade pollutants, commonly used in processing waste water or factories’ air purification.

During biofiltration, the polluted matter (dirty water, or in Naava’s case, poor indoor air) is filtered through organic materials and micro-organisms. The good microbes living in plants’ roots break the pollutants down into nutrients for the plants.

In Naava’s biofiltration system, the air circulates through the plants, plants’ roots and our growth medium, forming a natural air purification process.

From plants into biofilters – Naava’s acceleration process

Plants are the eye-catching piece of Naava, but to understand the air purification technology, it’s better to dig a bit deeper to what’s inside. Every pot in Naava acts as an efficient biofilter which Naava’s air flows through.

 

SELECTED PLANT SPECIES

The plant species we use are carefully selected for air purification efficiency and resilience and meticulously tested to ensure high quality and visual impact.

 

REFINEMENT OF PLANTS

Traditional soil is washed off the plants, which are then replanted into a
soilless, porous growth medium and special Naava pots which together
enable enhanced air circulation.

 

UNIQUE, SOILLESS GROWTH MEDIUM

Our very own invention, the soilless growth medium activates the
microbes of the plants’ root system, enabling the air purification
efficiency of Naava.

These four things combined create a Naava biofilter that naturally purifies air.

Naava has a measurable effect on indoor air – scientifically proven

The idea that had its roots in NASA’s research and the innovative product development that sprouted from that reached a significant milestone when Naava’s biofiltration technology got scientifically proven. The natural air purification technology of Naava Green Wall has now passed scientific research and has been proven to work by BRE.

Naava is scientifically proven to reduce harmful chemicals from indoor air

The study proves that Naava reduces the harmful chemical MEK (methyl ethyl ketone) by 57% with a single pass. The result was based on a single pass through Naava, and as air flows over and over through Naava and its biofilters, it means that Naava is an effective air purifier, reducing vast amounts of pollutants from the air.

Dr. Fraser Torpy, Director of the Plants and Environmental Quality Research Group and Senior Lecturer at the University of Technology Sydney, who led the test group, summed up the results in a great way:

“The Naava system represents an innovative approach to green wall technology, combining a range of best practice techniques derived from scientific studies around the world, and we were not at all surprised to discover that it had exceptional pollutant removal capacity. The testing regime we developed was the most rigorous yet seen in the scientific testing of these systems, and the system exceeded our expectations in all regards.”

“Active green wall technology for air pollutant removal has been a quantum step in our field of research, and the Naava system is a leader in the practical implementation of this new technology. This system has the potential to revolutionize the way we perceive indoor environmental quality.”
