The mineral substrate is the heart of the AIRY system and makes the natural air purification through plants particularly effective. Unlike conventional potting soil, it offers numerous advantages for a healthy indoor climate – ideal for bedrooms, offices, and living spaces.

1. High air permeability for effective air circulation

The substrate consists of air-permeable mineral components such as expanded clay or zeolite. These allow air to flow through the plant container to the roots. This supports the so-called chimney effect in the AIRY system, enabling pollutants like formaldehyde or benzene to be optimally broken down via the roots.

2. Protection against mold and rot

Since the substrate is germ-free and non-organic, it does not provide a breeding ground for mold fungi or rot. Especially in moisture-prone rooms like bedrooms or bathrooms, this ensures hygienic conditions and healthy plants.

3. Optimal moisture regulation

The mineral substrate stores water and releases it evenly and as needed to the plant roots. This prevents both waterlogging and dryness. Plant care becomes significantly easier and less frequent – ideal for everyday life.

4. Durable structural stability

Unlike soil, the AIRY substrate does not compact, remains air-permeable, and retains its structure – even over several years. This means: long usability without replacement and consistently high cleaning performance in the room.

5. Additional pollutant binding

Components like zeolite or lava granulate in the substrate can even bind volatile organic compounds (VOCs). This makes the system doubly effective: The plant filters the air – and the substrate actively supports pollutant absorption.

Conclusion: The mineral AIRY substrate combines air purification, hygiene, durability, and ease of care at the highest level. Those who value clean indoor air, healthy plants, and a low-maintenance system benefit sustainably from this well-thought-out substrate solution.
