Review: Highly recommend for anyone who needs to monitor their lung function regularly. - I've been using the MIR Smart ONE spirometer daily for several weeks now, and it has become an essential part of my health routine. The device is incredibly convenient—small enough to fit in my pocket, yet powerful enough to provide accurate PEF and FEV1 measurements. The app integration is seamless, making it easy to track my lung function over time. I appreciate how quickly I can take a reading each morning; it takes less than a minute from start to finish. What I love most is the peace of mind it provides. Being able to monitor my breathing daily means I can catch any potential issues early and adjust my treatment accordingly.
Review: Accurate and easy to use! - I love this product because it allows me to keep track of my peak flow and FEV1. It is accurate. (I had testing done the same day I got mine in the mail!) It's very easy to use. My pulmonologist suggested this to use a few times a week between my doctors appointments. It doesn't take the place of the pulmonary testing that is done in the clinic but it definitely helps to gage my breathing. It allows my doctor to help monitor me better. The app is free and I can track my symptoms as well as put notes in each time I test. It creates a shareable PDF chart/graph which I can send to my doctor. I'm very impressed and thankful for an affordable price tag!

## Questions & Answers

**Q: Can it calculate fev1 / fvc?**
A: no, the device does not calculate this ratio because it does not measure FVC.  It measures  and trends Peak Flow (PEF) and the Forced Expired Volume at one second (FEV1)

**Q: how accurate is it?**
A: My unit functions very inconsistently. At times out of 3 readings, I will register a 480, 20, 25. Other times, it will only register two of my three readings. I get too many readings in the 20s, then all of a sudden it will throw in a 520 etc., that I am not sure I can trust it anymore. I am currently shopping for another unit.

**Q: Which app can calculate fcv, fef25/75, fev1/fvc? my fev1 is at 40 percent and i have no diagnosis yet.**
A: Hi. MIR Spirobank App can calculate fcv, fef25/75, fev1/fvc and more. But this app is not compatible with MIR Smart One device. The compatible device is MIR Spirobank Smart. You can email us for further info on how to get this device (not available on Amazon for the moment). Please visit spirometry.com and fill in the contact form. Thank you!
