by Microlife • Model: PF-100 / PF-100-1
The Microlife PF-100 is an electronic peak flow monitor used to measure 'Peak Expiratory Flow' (PEF) and 'Forced Expiratory Volume in 1 second' (FEV1) for the home monitoring of respiratory conditions such as asthma and COPD. It features a rotating vane turbine method for measurement, providing greater accuracy than standard mechanical meters. The device includes a built-in memory for 240 readings with time and date stamps, and allows for data to be uploaded to a PC for professional analysis.
Eligibility may vary by provider and plan. Check with your HSA/FSA administrator for specific details.
Evidence-based evaluation by medical professionals
"The Microlife PF-100 is a robust, clinical-grade digital monitor that excels in measurement accuracy and standalone functionality for comprehensive asthma and COPD management."
The Microlife PF-100 / PF-100-1 represents a gold standard in digital peak flow monitoring, bridging the gap between traditional mechanical meters and modern app-based monitors. As an FDA-cleared Class II medical device, it is unique for offering an integrated LCD display that provides immediate readings for both Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1), eliminating the mandatory reliance on a smartphone. The core of the device is a removable digital volume transducer featuring a low-inertia rotating vane supported on jeweled bearings. This turbine-based architecture uses infrared beam interruption to measure rotation speed, providing a highly linear and precise relationship with airflow. Clinical performance evaluation confirms the device meets American Thoracic Society (ATS) standards and has been validated against standard pulmonary waveforms. With a built-in memory for 240 readings and a dedicated risk indicator system, it provides users with immediate clinical context. While it lacks Bluetooth, the included USB tracking software allows for detailed data analysis and report generation, making it a reliable tool for long-term respiratory tracking in both pediatric and adult populations.
