Expert Review Summary

Our clinical assessment and verdict for each device

Safey Connected Peak Flow Meter

Highly Recommended

"The Safey Connected Peak Flow Meter is a top-tier digital respiratory monitor that excels in accuracy and data integration for patients requiring detailed lung health tracking."

The Safey Connected Peak Flow Meter represents a significant advancement over traditional mechanical devices by integrating a high-precision turbine sensor with mobile connectivity. As an FDA-cleared Class II medical device, it measures both Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1), providing a more comprehensive view of lung function than standard meters. Our evaluation focused on the device's technical architecture, specifically its use of the infrared interrupt concept. This design uses a vane that rotates based on airflow, with infrared pairs detecting rotation speed and direction to calculate results. This method significantly reduces the friction-related errors often seen in mechanical spring-based systems. Clinical performance data demonstrates that the device adheres strictly to American Thoracic Society (ATS) and European Respiratory Society (ERS) standards for spirometry. The companion mobile application automatically categorizes results into standardized green, yellow, and red zones, simplifying the implementation of asthma action plans. The build quality is robust, featuring medical-grade polymers and an IP22 ingress protection rating, making it suitable for both home and clinical environments.

MIR Smart One

Recommended

"An accessible and user-friendly Bluetooth spirometer that excels in tracking basic asthma metrics like PEF and FEV1, though it lacks advanced parameters for complex COPD staging."

The MIR Smart One stands out as a premier over-the-counter (OTC) entry point for decentralized respiratory diagnostics. Our evaluation focused on its ability to provide accurate Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1) measurements in a home environment. Utilizing a reusable, factory-calibrated turbine flowmeter and Bluetooth Low Energy connectivity, the device interfaces seamlessly with the MIR Smart One mobile application. While it does not capture Forced Vital Capacity (FVC) or other complex parameters needed for advanced COPD staging, clinical testing protocols demonstrated high concordance with laboratory spirometry equipment for the parameters it does measure. The inclusion of an automated traffic-light indicator system makes it exceptionally well-suited for patients tracking daily asthma symptoms and identifying early signs of airway narrowing.
