Certified accurate to American Thoracic Society standards, it measures Peak Expiratory Flow (PEF) and Forced Expiratory Volume (FEV1), stores 240 readings, and features an early warning traffic light system for asthma attacks. The kit includes multiple mouthpieces, a premium storage case, and free software compatible with Windows and Mac for tracking and sharing results with healthcare providers. ## Description Product description This device is used to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) in both children and adults. Doctors can have patients monitor changes in airflow and record the results at home using the Microlife Peak Flow Meter. Patients can send results via PDF or CSV to their healthcare provider by using the included software. Connect via USB to use the free Microlife Asthma Analyzer Software to View, Track, and Share Results. Compatible with both Mac and Windows PC. Who should use this meter? Asthmatics Chronic Obstructive Pulmonary Disease (COPD) Other Respiratory Problems Athletes Superior digital accuracy Accuracy: Superior to mechanical methods, digital peak flow meters provide an exact reading, avoiding any accidental mistakes. The meter measures the flow rate at one hundredths of a liter per minute, and the results are automatically recorded. Consistent and accurate readings will improve your ability to accurately assess your condition. Memory: Automatically stores 240 readings The highest reading from each session is automatically stored, allowing you to test multiple times and record your best result. Reports show that patients who measure and record their readings are better able to monitor and manage their conditions. Peak Flow and FEV1 tracking software Connect your meter to your PC and automatically download your readings. With the user friendly analysis software, you can chart your progress print graphs make notes about your symptoms or triggers export your results to a spreadsheet share your result with your health care provider Use & Care How to take a measurement Step 1: Standing up, hold the peak flow meter as shown with both hands. Step 2: Take a deep breath and blow into the mouthpiece as hard as you can for as long as possible. Step 3: As you exhale, bend forward as shown to push all the air from your lungs. Step 4: Measure your peak flow rate twice daily and close to the same time each day. Complete instructions in English/Spanish included. How does the risk indicator work? Whether you are using national standards, or your own customized numbers, the green, yellow and red bars on the display are a quick visual reference to show how your results compare. As your peak flow raises or lowers, the arrow on the display will show the measurement as within the normal (green), borderline (yellow) or in the danger (red) range. What do the colors mean? Green = 80% or higher than your personal best Yellow = 60 - 79% of your personal best Red = 50 - 59% of your personal best How do I clean my monitor? Simply separate the mouthpiece and measuring tube from the meter, then clean the parts with soap & warm water. Air dry. Removable mouthpiece Designed for all ages, this monitor comes with 3 color coded mouthpieces. Use them to monitor yourself and your child, or rotate them between uses for cleaning. The Microlife Digital Peak Flow Meter with FEV1 is the doctor's choice for managing diseases that restrict lung performance. This advanced meter for spirometry includes a digital diary and measures air flow velocity and volume (FEV1) to indicate early warning signs for impending asthmatic incidents or conditions. Using these measurements in conjunction with a doctor's consultation allows patients with asthma, COPD and other lung diseases to manage their condition. What is PEF: PEF is Peak Expiratory Flow, or in other words measures how fast you can push air out of your lungs. What is FEV: FEV is Forced Expiratory Volume, or in other words measures how much air a person can exhale during a forced breath. Specifications Review: It actually works :) - This meter works very well. I bought it for a friend of mine, because of the fact it has the Peak Flow measurement(large airway) and the FEV1 Measurement (small airways). Although this is not as good as the spirometry units pulmonologists have, this unit is portable, and can be used anywhere. You no longer need to go to your pulmonologist every week to see if your medication/lifestyle changes are working for you now. You can track your readings using the software they sell at the site (this unit does not come with it) and you can take the print out to your doctor after 256 measurements. It really helps to give peace of mind, and to see if you are actually improving or getting worse in certain environments, at certain times, after a cold, flu or bronchitis. You can use it anytime as much as you want, that is the best thing about it. I do not know about the actual accuracy of the calibration, but my friend says that the Peak flow of this unit is inline with other meters, and it is pretty close to the FEV1 readings of the Hospital Models. You can always take it with you to your doctors when you have a spirometry test and then use it there to see how far off it is anyway. It is great to have all the readings there stored in the unit at your fingertips without having to write down the time and date and readings. Just make sure you upload it to your computer before you get to the limit or it erases your initial measurements The unit is great. Review: Great product! Carrying case, Mac app, export to PDF/CSV, nice pro medical package - WOW, I read the good reviews but.. WOW. I love when a medical device really lives up to what you expect, and goes beyond! It comes with a nice heavy duty cloth carry case w/ 2 zippered compartments: one for the manual and paper medical records, extra mouth pieces (green and orange in addition to the attached blue), and the USB cable for software interface; the second larger compartment for the device. Comes with two AAA batteries too. Easy to install. Setting up time is easy too. Remove a cover to access the time editor, then set date/time elements, using a paperclip to press a button. Easy enough. Note that the month/day appear in Euro style, DD/MM (vs USA MM/DD). OR you can use software to set it! VERY COOL! The product mentions software for PC... but the company has an app for the Mac too. It's called Microlife Asthma Analyzer+, free on the App store. Setup a profile using an email address... but it actually stores locally and doesn't use the email. When you connect, it will notice your date is not sync'd, and offer to sync it from your Mac. VERY COOL. After using the product, you can view the data, PEF and FEV1 in charts, or EXPORT to CSV (for data points) or PDF (printable color copy of the chart). Use a sync button (two arrows, top right) to pull data from the device. To use, it's important to know that you BEGIN by pressing the big button, WAIT for the beep, then exhaling gently, THEN put your mouth on the device BEFORE doing a big inhale... THEN exhale as fast as you can. It helps to purse your lips a bit. The idea on the inhale AND exhale is that you're letting it get a good measure of volume. After one reading, wait between 2-30 seconds (max) and repeat... then do the same for a third time. The system will save the highest readings of the three. The SOFTWARE will also use your first set of readings to determine your BASELINE. That way the green/yellow/red areas reflect how well your future readings match up to that baseline. This is useful if you can set up a baseline when you are breathing well, and then the yellow/red will just warn you if you're dipping too low below that baseline. OR you can use their charts (or online charts or a number provided by your physician) to SET your BASELINE. You can set that up in the software, with the device connected, and it will update the device. That way your readings will show green/yellow/red based on that number. This is useful if you are already having breathing issues (asthma, COPD, heart-related respiratory or post-COVID issues), to know how bad your breathing is, and have a good idea when it's probably time to see a doctor (if it dips into the red). Again, VERY COOL. So overall, I absolutely recommend this device! I'm so impressed that I'm looking into what else they offer. It's hard to find consumer medical products that are so well designed and operate well too. Microlife truly scored "11" out of 10 on this one. ## Features - Certified Accurate For All Ages: Monitor asthma, COPD, and other chronic respiratory conditions at home; Suitable for both pediatric and adult patients; American Thoracic Society (ATS) standards for accuracy - Early Detection for Asthma Attacks: Respiratory Risk Indicator (traffic light zones) alert to asthma attacks in advance, before you feel it; Contact your doctor in these instances - Measure PEF & FEV1: Stores 240 readings; Peak Expiratory Flow Rate (PEF) measures how well you are breathing; Forced Expiratory Volume in one second (FEV1) measures how well the lungs are working - Stay Clean & Organized: Removable mouthpiece and measuring tube are easy to clean; Kit includes x3 mouthpieces; Premium two-tier storage case keeps everything separated and ready for use - Free Monitoring Software: Connect to computer via USB to upload results to the Microlife Asthma Analyzer; View and track results, customize traffic light zones, and share results with your doctor; Windows and Mac compatible ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 1,483 Reviews | ## Images ![Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Image 1](https://m.media-amazon.com/images/I/71VoA9MCGLL.jpg) ![Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Image 2](https://m.media-amazon.com/images/I/81IviVh5ezL.jpg) ![Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Image 3](https://m.media-amazon.com/images/I/91VZwACxNzL.jpg) ![Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Image 4](https://m.media-amazon.com/images/I/71BE3aI6hbL.jpg) ![Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Image 5](https://m.media-amazon.com/images/I/71dgx5HA+nL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: Does the free downloadable software work on a Mac?** A: It does not work on MAC.

The flow meter kit I received came with three mouthpieces; one blue, one green and one purple. The manual has instructions for cleaning the mouthpiece after each use. **Q: What is the highest reading fpr the microlife?** A: One reading seems never to exceed 100 and hovers near 60 and the other never exceeds 1.0 and hovers near .8 for me. **Q: Does this product include the factory analysis USB cable?** A: Obsolete USB? Yes. But no USB to USB-C adapter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It actually works :) *by C***Q on June 30, 2007* This meter works very well.

Maybe now I'll actually stick to the routine my Doctor wants. *by G***G on January 6, 2013* Prior to ordering one of these you should know the difference between a Spirometer and a Peak Flow Meter. A Spirometer measures the total volume of air that can be exhaled or inhaled. It can also measure the rate at which a certain volume of air is expelled from the lungs. A Peak Flow Meter, on the other hand, only measures the rate at which air is forced out of the lungs. This is known as the peak expiratory flow. Some reviews here seem to have the two confused so I wanted to get that out of the way. I have a manual Peak Flow Meter from the Doctor and never used it much for my Asthma. Needed to use up some FSA money before the end of the year and this item fit the bill as the price was just right. The item arrived with the box containing everything that comes with the item (USB cable, batteries, spare mouth pieces, directions and a nifty carrying case). The included directions are good enough to setup and operate the device. I downloaded the software from Microlife's website for free, installed it on a Windows XP Computer without issue (I think the software supports later versions). The software is able to communicate with the unit and pull the readings. Setting up the software only involves creating a "Patient" by inputting some information. You can create multiple patients which is cool because any device of this type at this price point usually doesn't support multiple users. So while it's cumbersome using this device along with the software it's possible to save readings for multiple patients. The software allows for printing graphs or just the data so I can take them to my doctor's appointments as he's always asking me if I use a Peak Flow Meter and what are the readings. You can also export the data to a CSV (Comma, Separated Value) file. This brings up an important point. All Peak Flow Meters are designed to aid in the diagnosing and treatment of a respiratory illness. Which means you should be seeing a doctor to help interrupt the results and plan your treatment. I took several readings with this meter then several with the manually operated one the doc gave me and they were very close so I have confidence this device is working as intended. All in all I am happy with my purchase. I refrained from rating it 5 stars as anything can be improved upon. Asthma or COPD cannot be cured but effectively managed. This device does what it's supposed to do and aids in that. ## Frequently Bought Together - Microlife (Deluxe Kit) Digital Peak Flow Meter Tests PEF / FEV1 / Early Detection of Asthma Attacks | Spirometer for Kids & Adults | Perfect for Monitoring Asthma, COPD & other Lung Conditions at Home - Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Silicone Cover, Batteries and Lanyard (Royal Black) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1097804-microlife-deluxe-kit-digital-peak-flow-meter-tests-pef-fev1](https://www.desertcart.co.uk/products/1097804-microlife-deluxe-kit-digital-peak-flow-meter-tests-pef-fev1) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-03*
