Treely Air has developed an air purifying system in a green and sustainable way to reduce the environmental impact. This is especially critical during the energy crisis, coupled with the pandemic, with strong demand for air purifying solutions. We have built a series of air-purifying solutions with extra low power consumption and without the use of HEPA filters and other short-lifespan consumables. It has a one-size-fits-all modularisation design that is suitable for commercial use.
