A MADA 83 filter for a MIR spirometer
MIR is a well-known brand in the medical world and is known for the very pleasant spirometers that they market. Lung function is tested with a spirometer by requiring the patient to blow into it with great force. You can test lung function anywhere you want. A MIR spirometer is cheap to purchase and can therefore also be purchased by private individuals who want to test at home. What you must of course take into account is that you need a new MADA 83 filter for every new patient who uses the MIR spirometer.
