Recently, several research groups have focused on air pollution, which is the main cause of respiratory and pulmonary diseases in the world. The objective of sustainable development 3 (ODD 3) is directly linked to health and well-being. In addition, the challenge of dealing with natural solutions is limited. Lee and Kim (2018) indicated that the mortality rate due to air pollution was greater than 4.5 million worldwide in 2015 in 20151. The WHO 2024 report also indicates that household air pollution is responsible for 3.2 million deaths per year, including 0.2 million deaths for children. The criteria for estimating the mortality rate due to air pollution were assigned to the load of diseases caused by PM2.5, PM10 and nitrogen dioxide (no2))2. The magnitude will aggravate in 2025, as planned. The study also discussed the segregation and combined effects of inner and external air pollution. Odo et al. (2022) have reported a link between acute respiratory diseases and air pollution in children under the age of 5 in 35 developing countries3. This observation reproduces the harmful effects of air pollution on younger and future generations. Goldstein et al. (2020) reported and discussed the effects of the inner environment on exposure to air pollution4. They followed a story of questions and answers to determine the tangled relationship between the inner environment, air pollution and exposure. They linked the concentration of PM2.5 inside to outdoor air pollution and presented the challenge of exposure to more organic compounds due to closed spaces.
An examination on phytobrediation capacities of plants from yesteryear to prevent air pollution in interior spaces. Phytoremediation is a repair process that uses various plants to eliminate, stabilize and destroy contaminants in the soil, air and groundwater5. In this case, we take advantage of the phytoremediation of air pollutants. Kumar et al. (2023) also presented a review highlighting the need for natural solutions to the problem of air pollution. In addition, they discuss the various phytoremediation mechanisms to explore the molecular colony of pollutants through techniques of penetration of roots6. Some studies have been linked to predictive measures to quantify the AQI according to multifactorial functions, including AI and automatic learning algorithms7,,8. The prediction algorithm focuses on the search for the weight of the dominant parameter on the AQI but still focuses on the search for worthy solutions. Some studies have focused on the search for nature -based solutions to combat air pollution, but they focused on managing the external environment or space arrangement9,,10,,11. In addition, most AQI management works must integrate preventive and curative changes with technological / nature changes based on improvement. All the works cited has shaped current research in this area. This study aims to fill the gap between the use of natural plant solutions to combat air pollution The quality of indoor air (IAQI) and the environment. We offer new technology based on respiratory root technology, “Ubreat Rain”.
Ubreath Rain is an innovative system of air purification inspired by nature designed for large semi-open regions experiencing a heavy population. The semi-open regions are different from the interior regions because they also include outdoor openings for intentional ventilation. The system developed by Urban Air Labs uses a modular and wall design and introduces pioneer technologies to overcome the limits associated with existing air purification methods. Standard air purification technologies, such as mechanical filtration based on HEPA and charcoal filtration, are based on suction systems piloted by fans, leading to problems such as high power consumption, frequent filter replacements, environmental impact, increase in noise and ineffectiveness outside. Urban Air Labs takes up these challenges with a modular system incorporating “respiratory root technology” and “rain shower technology”. These technologies take advantage of the phytobrediation capacities and simulate wet deposit during precipitation to effectively purify air in semi-open spaces.
The first filtration layer implies “respiratory root technology”, inspired by the phytoremediation process, and is based on the results of research from those of those of those of those of those of those of those of those of those of those of those of those of those of those of those12,,13,,14which supports NASA’s conclusions15,,16,,17 On the capacity of plants to clean pollutants. “Respiratory root technology optimizes the breathability of the soil – root area, improving the phytoremediation process and improving the overall efficiency of pollution attenuation. In conventional planters, the root area of the soil remains locked up, limiting its exposure to ambient air and reducing its effectiveness in air purification. On the other hand, Ubreathe Rain incorporates an innovative planter design with strategically placed open slots, allowing direct interaction between the soil root area and the surrounding air. To avoid the loss of soil through these slits, the planters are lined internally with a cellulose material similar to a mesh, which serves both as a structural support and a functional filtration medium. This technology also increases oxygen and controls carbon dioxide levels through photosynthesis. In the implementation of “respiratory root technology”, a carefully chosen selection of plants establishes a layer including vegetable sheets and exposed root areas. The implementation of “respiratory root technology” implies a reasonable selection of plant species, strategically composing a stratum characterized by the symbiosis of leaf structures and exposed root systems. Organized assembly, distinguished for its exceptional phytorediation capacity, includes Dieffenbachia Compacta,, Epipremnum aureumAnd HEDERA HELIX18as well as Elastic ficus,, Pachira aquatica,, Podophyllum syngonium19,, FICUS BENJAMINE,, Gerbera jamesoniimiscellaneous Philodendron species, Sansevieria Laurentii,, and spathiphyllum ‘Mauna Loa‘20. The second filtration layer imitates the precipitation cleaning effect thanks to “rain shower technology”. The wet deposit, a natural process in which atmospheric pollutants are eliminated by precipitation, is scientifically explained by parameters such as the size of the droplets and the loads present in the droplets21. Consequently, the rain optimizes the size of the droplets and the load balance to maximize the wet deposit capacity. This technology effectively absorbs gases and decomposes into simpler and non -harmful shapes.
The rainfall system consists of holes strategically placed in a hose nourished with water through a submersible pump. Optimized diameter nozzles facilitate the formation of droplets, thus guaranteeing maximum efficiency. The ion splainer inside the module strategically emits the positive and negative ions, which load the droplets which interact with the suspended particles and the harmful gases, thus increasing the coagulation capacity of the droplets. In natural ecosystems, wet deposit is essential for reducing pollutants suspended in the air by taking advantage of ions to improve the aggregation and elimination of particles. The ions, whether from rainwater, humidity or artificial sources such as ionizers, help neutralize the particles suspended in loaded air, which makes them come together and set up with air more effectively. This mechanism considerably improves the decantation and gravitational deposit, which makes the systems of air purification more effective. Without ions, the elimination of pollutants is based solely on passive filtration and microbial degradation, which can be slower and less effective in capturing fine particles. Figure 1 Watch a diagram of the Ubreathe rain shows a transverse cup view. Ubreathe Rain, provides a new solution to control air quality in large semi-open spaces with loads of unpredictable pollutants. The modular design allows scalability, and the energy module per unit is significantly lower than that of conventional air purifiers with similar specifications and coverage areas. This innovative air purification system offers a lasting and effective solution to improve air quality in densely populated areas. Throughout the manufacturing and tests, the space was very selective due to the emphasis placed on the vicinity of the combustion of the thatch. In addition, the moment and duration have been chosen, in particular to target the combustion of the thatch. These specific choices can set limits with variations under demographic conditions, which has increased fluctuations in the efficiency of deployed products. However, the efficiency of the technology offered is limited in highly ventilated spaces due to the great rate of air change, opportune sunlight, which rejuvenates the follicles of plants and dependence on the lightning of water.
