Abstract: The presented study deals with sustainable solutions for air filtration. A panel pleated air filter has been reconstructed, developing a new modular filter design and using recyclable textile material for the filter mat. The proposed detachable design allows replacement of only the filter core, instead of disposing the entire filter. The polyester needle-punched textile material used can be obtained from recycled fibers, and at the same time is also recyclable. The initial pressure drop deviation is 5 to 20% lower compared to conventional HVAC filters of the same class. The results of the development help break the widespread negative practice of discarding HVAC systems filters after a single use. The operational life of air filters is extended with saving valuable raw materials and energy. Since coarse and medium efficiency filters have an average lifespan of six months, the new modular filter system design is expected to use 13,4 times less galvanized steel for the metal housing over a 10-year period. When using the prototype, the initial investment is reduced by 17% compared to filters available on the market. In addition, over a ten-year period, the savings from ongoing maintenance costs would amount to approximately 36,3% amounted to EUR 26354.
