Fine filters replacement, M6 filtration class (EN 779: 2012) with filters compact, F8 filtration class (EN 779: 2012) because, besides a more efficient filtration allows passing a higher air flow than bag filters, M6 filtration class. Next step was delivering the recommended products. Results The successful implementation of the proposed solution in the restrictions required by the ventilation and air conditioning system and meeting air purity standards inside the hotel. Used products: Bag filters, M5 filtration class Compact filters, F8 filtration class
