Over the next decade, the air purification machine will become the new pet of household electricity, and it will be the second type of household electricity, mainly for routine indoor air purification, improvement of indoor air quality, as well as the introduction of household appliances such as air conditioning and colour electricity. Excellent teams, advanced technologies and high-quality production, and the successful introduction of the shui air cleaner in terms of efficiency, safety, environmental protection, intelligence, etc., have led to the adoption of international and national tests and numerous certifications. High-precision, high-quality components from germany and japan integrated advanced photovoltaic technology and environmental conservation concepts in the united states, and shul air passed through indoor environment and indoor environmental product quality monitoring. Inhalable particles, such as cigarette smoke, dust, pollen, etc., are also completely cleansed of invisible contamination such as formaldehyde, benzene, ammonia, tvoc (which has a more severe effect on three types of indoor air quality), bacteria, etc., in indoor air, which makes it difficult for the same product to find its back. Schul air cleaners have gained international recognition, european ce certification prior to the product being put on the market, and rohs environmental certification meeting european and american standards. The schul air cleaners are below the threshold. Attracting a wide range of self-entrepreneurs who dream of being motivated, the aim is to find a strategic international partner for the shul air cleaner, to work together on branding and channel integration, to gain yin's advantage and to contribute to air pollution management. Negative ion air cleaners are also a very promising entrepreneurial project for the next decade. Many indoor air pollution is now more severe than outdoors, and the adsorption, purification and greening of harmful substances in the air by green plants alone is far from sufficient. The health benefits from sufficient ion content in indoor air, which slows the flow of blood, increases the oxygen content of blood by increasing the condensation time, and facilitates its transport, absorption and use. Negative ions enter the human body through the absorption channel, which increases human lung activity and improves and enhances lung function. Negative ions are called air vitamins。
