PeakAir Peak Flow Meters

PeakAir peak flow meters give people with asthma and other airway conditions a simple, reliable way to measure how forcefully they can exhale — a key early warning of narrowing airways, often before symptoms feel obvious. Monitoring peak expiratory flow at home helps patients and clinicians spot changes, adjust medication, and follow an asthma action plan with confidence.

The PeakAir Peak Flow Meter (PF9940) is built around exactly that daily-use reality. Its compact design fits easily in a bag, drawer, or school backpack, and the clear scale makes it straightforward to read a result and record it. Because it's rated for both adult and pediatric use, it suits families managing more than one person's readings, as well as adults who want a dependable meter without unnecessary complexity.

Using a peak flow meter is simple: stand up, take a full breath, seal your lips around the mouthpiece, and blow out as hard and fast as you can. The best of three attempts becomes your reading. Tracked over time, these numbers establish your personal best and reveal when your green, yellow, or red zones shift — the kind of trend that turns guesswork into a plan you and your provider can act on.

A meter earns its keep through consistency, so keep it clean and use the same technique each time. Wipe the mouthpiece regularly and check that the marker slides freely so readings stay accurate day to day. The PeakAir's white, uncluttered housing makes it easy to see the indicator clearly in any lighting.

PeakAir supports the broader goals of home respiratory care — putting a practical monitoring tool in the hands of the people who use it most. Explore the full collection to find the meter that fits your household's needs.
