MIR Smart ONE | Personal Pocket Spirometer | Peak Flow (PEF) and FEV1

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.

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!

Works great. Easy, app works well and is easy to use.

If you’re interested in tracking your FEV & PEF this is a very helpful and user friendly tool to do so. Cool product, works great, connected to my iPhone flawlessly. Proud to add this tool to my health tech arsenal! The only reason I give it 4/5 is because the companion app could use a little bit of improvement. Very solid product!

Can't believe I didn't rate this, purchased September 2022 and use it every day (morning and night). Great Iphone app, zero connectivity problems, and the instrument itself still functions perfectly. I would definitely recommend and certainly will buy another if this one ever fails.

Worked fine or a year or two. Would have given it five stars. Then their app was "updated' and functionality was impaired. It only functions in "peak flow" mode, requires three trials when testing, but only reports results of two of them. It also seems to wait interminably after each breathing test before going on to the next. I'm using a Samsung Android v16. Their Android software is screwed up, and has been for months now. I tried to load an earlier version of their software but that was blocked by my Android 16 security. The company has failed its Android users and seems not to e doing anything about it. If you have an iphone you may be good to go. But they do not care about Android users....

This product is fantastically portable and seems to be accurate. I was checking how my daily inhaler affected/improved my lung capacity in the morning and at night -- it is great to be able to track your trigger days and symptoms. I was able to find that my asthma affected my breathing most in the mornings, before I took my maintenance inhaler. I appreciate that the app walks you through the process and recommends your exhale slower or faster, depending on your tendency. Note: It does take the highest of three measurements and saves that number. With all that being said, I bought it to help me track whether my medication was actually helping my lung function or not. It gave me a lot of relief that, even when I felt like I was having an asthma flare, my lung function was still generally good. It is worth it for the peace of mind! My only complaint is that I wish the mouthpiece was collapsible. For some reason, I assumed it was, based off of the product photos, and was disappointed to see that it wasn't. In reality, that is a very small quirk to an otherwise sleekly designed piece of medical equipment.

Out of the box to testing in about 5 minutes! The readings are accurate- if only relatively speaking. When I'm open it's high and when I'm plugged up it's low. I'll take it to my next pulmonologist appointment to compare, if possible. I love the fact that it's Bluetooth and the ease of use. I wish someone would come up with a (home) Bluetooth blood pressure cuff, pulse oximeter breathing analyzer, and perhaps a thermometer.. I've got them all except the thermometer BUT each runs on its own app. I see this sensor I just bought now comes with a pulse oximeter. Who knew COPD would have a fun edge to it?
