The first plant-based biofilter

Fresh into spring

Do you know that?

Headache? Irritated eyes? Dry nose? Fatigue?

World Health Organization (WHO)

"Western Europeans spend 90% of their time indoors. The air quality there is up to 30 times more polluted than the air outside."


Innovative technology in harmony with nature

AIRY is an air purification system based on NASA research. NASA discovered that certain plants with aerated roots can remove up to 90% of pollutants even if their leaves are missing.

Based on these findings, we developed the AIRY system and patented it worldwide. AIRY uses the natural cleansing effect of plant roots and enhances it. Each component of the AIRY system fulfills a specific function to achieve a perfect harmony of high-tech and nature.

This is how AIRY works

One system, many advantages

What does AIRY do for me?

Better air quality

The AIRY biofilter absorbs harmful gases and odors.

Optimal humidity

The plant ensures your perfect feel-good climate.

Performance around the clock

Of course without electricity, annoying noises or expensive filter changes.

Green thumb

The water level indicator shows you when you need to water. And you'll never have to repot again!

Easy to care for plants

Air-purifying plants essentially feed on air and love. And water.

Natural atmosphere

Plants have a calming effect on our psyche. Without electricity, annoying noises or expensive filter changes.


NASA confirms the effectiveness of AIRY

“In the 1980s, researcher W. C. Wolverton of the Stennis Space Center investigated how to maximize the air purification potential of houseplants. He found that, perhaps counterintuitively, the roots of plants and associated microorganisms in the soil did most of the work, rather than the leaves of the plants. Based on this research, AIRY GreenTech, a company based in Hamburg, Germany, has designed plant pots that maximize airflow through the soil and roots to increase air filtration and improve plant health. The products are available in approximately 50 countries worldwide.”

Air is our most important food. Statistically speaking, we consume 350,000 kilograms of air over the course of our lives. This is ten times more than food (35,000 kg) and five times more than liquid (70,000 kg). Source: Austria Federal Ministry of Agriculture, Forestry, Environment and Water Management

Especially volatile organic compounds (VOC) such as formaldehyde, toluene or benzene. They are contained in building materials, furniture or technical devices and evaporate continuously over years. Fine dust (from printers and copiers) also plays a role.

Nope. Technical systems are (very) expensive to purchase and require ongoing measures and investments (energy, maintenance, filter changes). Since these are filter systems, the pollutants are only collected. Fresh air is not produced - unlike plants.


The number of plants required depends on the size of the room, the level of pollutants and the sensitivity of the people who live there. The rule of thumb is: an AIRY system in size S is sufficient for rooms up to 10 square meters, sizes M and L for up to 20 and 30 square meters respectively.

According to the WHO, indoor air is up to 30 times more contaminated with pollutants than outdoor air. Since people now spend around 90% of their time indoors, the effects are immense: the first symptoms of poisoning are mood disorders such as headaches and fatigue. Science speaks of the “Toxic Home Effect” or “Sick Building Syndrome”.

Ventilation helps against CO2 pollution in the air - but that is only part of the problem. In particular, pollutants from furniture, carpets, paints, varnishes and cleaning products evaporate and accumulate in the indoor air (so-called VOCs, volatile organic substances). Fine dust, caused for example by road traffic, can also penetrate into the interior through ventilation and pollute the indoor air. The AIRY biofilter collects all these pollutants - and is constantly cleaned by the plant roots.


Yes. Without plants, life on planet Earth would not be possible. NASA has therefore researched how plants can be used to purify the air in space. She examined 30 different plant species for their air-purifying properties. The result: There are certain plants that, over the course of evolution, have specialized in feeding themselves “from the air”. These plants mainly come from dry, hot regions and are ideal for cleaning indoor air.

Plants absorb air through their leaves as part of photosynthesis. They transport the pollutants they contain to the roots. There the pollutants (especially VOCs) are broken down into their basic chemical components (amino acid, starch, glucose) by plant enzymes and microorganisms. Means: The pollutant is converted into nutrients for the plant without leaving any residue. As part of the NASA study mentioned, plants were completely ventilated (including the roots). If the leaves were removed, the plant's performance only decreased slightly (5-12%). This led to the conclusion that only ventilation of the root system enabled the plants to achieve their full potential.

The AIRY Base consists of lava, pumice and zeolite rock. This power mixture developed by scientists significantly expands the effectiveness of the AIRY. The fine-pored stones promote root aeration thanks to their coarse grain size. In addition, they absorb an extremely large amount of water, which they gradually release to the plant roots. Odors and pollutants also get caught in the fine-pored structure thanks to the air supply from below. The capillary effect ensures the continuous absorption and residue-free release of pollutants from the substrate to the roots. This means that the rock does not become clogged. Unlike industrial filters or activated carbon filters, the substrate never needs to be replaced.

Hydroponics is a system in which plants grow without soil. In such systems there are no microorganisms, but they are essential for the growth of plants. The absence of these organisms can cause plants to rot and produce harmful bacteria. This can lead to health problems for us humans indoors.

The proverbial “thick air” indoors has a variety of consequences:

  • Mood disorders (headache, fatigue, mood swings, poor concentration, loss of appetite, nausea, sleep disorders)
  • Irritation of the respiratory tract and eyes
  • Allergies and hypersensitivitiesThe proverbial “thick air” indoors has a variety of consequences:

That depends on the plant growing in the AIRY. Scientific research has identified about 30 plants that are particularly effective against airborne environmental toxins. These are typically so-called “air roots” from the rainforest or desert plants. These plants are able to metabolize volatile organic compounds (VOCs) such as formaldehyde, benzene or toluene.

The AIRY system

We use the “chimney effect”: differences in temperature and pressure as well as air movements in the room ensure that air at the bottom of the pot gets into the inside and can rise between the inner pot and the outer wall and leave the pot again.

Never. The pollutants are removed without leaving any residue, so there is no “landfill on the windowsill”. In addition, the annoying repotting is no longer necessary: ​​Due to the nature of the inner pot, the water-bearing roots stop growing (“air pruning”), leaving significantly more space for the nutrient-absorbing hair roots. This promotes the rapid and healthy growth of the plant.

An AIRY system consists of three components: pot, substrate and plant. In order to offer easy care and the best possible guarantee of success, we have developed our own mineral substrate. It offers the plant an ideal home.

Only light and water are required for ongoing operation. Both depend on the plant. The pot's water tank ensures pleasant maintenance intervals. Experience has shown that the system needs more water in the first few weeks until the humidity in the room has regulated.

The pot systems are manufactured on our behalf by a medium-sized injection molding company in North Rhine-Westphalia.

We developed the mineral substrate together with the Klanz company. Pumice and lava are mined in the Eifel, the zeolite comes from Slovakia.

We source the plants directly from Holland. They are quality tested by the “Orchideen Wichmann” nursery in Celle (Lower Saxony) and sent to our customers from there.

Yes, several times. Recently, the Fraunhofer Institute has carried out extensive studies using various pollutants (xylene, toluene) as examples. Compared to a plant in a conventional pot, the AIRY system was many times more powerful. The studies are available here:
