I'm in search of specific filters designed for my ventilator model, and I need to ensure they have plastic edges just like the originals from the factory. It's crucial that these filters meet the exact specifications to maintain the performance of my device. Could you please provide me with information on where I can purchase these filters? I'm looking for reliable sources that supply the original factory products. Your guidance on this would be highly appreciated. Thank you!
