Expert Review Summary

Our clinical assessment and verdict for each device

Sonmol Upgraded Digital Peak Flow Meter with ePEF App (SMPF-2S)

Worth Considering

"An affordable, Bluetooth-enabled digital peak flow meter that successfully bridges the gap between basic manual meters and premium smart spirometers."

The Sonmol Upgraded Digital Peak Flow Meter (SMPF-2S) builds upon the brand's entry-level model by adding crucial Bluetooth connectivity. Designed primarily for asthma and COPD management, it utilizes a differential pressure transducer to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1). The device features a built-in LCD screen for immediate readings and a Smart Risk Indicator that categorizes results into Green, Yellow, or Red zones based on the user's personal best. Unlike its predecessor, the SMPF-2S syncs seamlessly with the ePEF mobile app, allowing patients to track longitudinal trends, log symptoms, and share digital reports with their doctors without maintaining a paper diary. While it lacks Forced Vital Capacity (FVC) measurements and the rigorous maneuver quality prompts of more expensive clinical models like the Vitalograph asma-1 BT, its inclusion of two detachable mouthpieces and a sub-$90 price point make it an excellent mid-tier choice.
