Virus & Bacterial Filter

Mada Filter: Highest filtration efficiency and comprehensive protection Our Mada filters are characterized by an outstanding filtration efficiency of 99.9%, tested by the independent Nelsonlab laboratory at a flow rate of 30 L/min, which corresponds to normal, calm breathing. However, a forced measurement is also crucial for lung function tests. The patient breathes in deeply and then exhales vigorously through the filter. At this load, the filter must achieve a filtration efficiency of at least 99.9% at 750 L/min. Our Mada filters meet this criterion and have had this confirmed by the CAMR test laboratory. In addition, our filters are specifically tested and certified against coronaviruses - an essential feature in today's healthcare landscape. A high-quality filter should also have a low flow resistance to enable precise volume measurement. Our Mada filters have a flow resistance of just 0.87 cmH₂O/L/s. Another advantage: the dead volume of our filters is only 38.2 ml, which is half the dead volume of other filters on the market. This is particularly important for smaller patients and children under 38.5 kg to ensure accurate volume measurement. We are convinced that modern filters must guarantee 99.9% virus protection in all applications. Anything else would not be sufficient, as there is no adequate protection against bacteria and viruses for patients, specialists and equipment. With our Mada filters you guarantee the best protection for your patients and your examination staff.
