- Making You Healthier and Happier Through Allergy Relief
Product Review (submitted on April 7, 2015):
For managing asthma, this Peak flow meter allows you to set your green, yellow and red zones. These don't move, so it reminds you where you are with your lung function. Also folds up small and doesn't take a whole drawer to store. It is even small enough to carry in a pocket or bag. Very discreet.
