There are 800+ breaths per device which is 4X as many as we previously had in our old model. Our new inhalers have higher functionality, more flavour and have a longer life. The majority of vitamin inhaler brands on the market will say they have 800 breaths but in reality there is only 200 due to the amount of liquid contained in each device. We pride ourselves on being the most affordable vitamin B12 inhaler on the market whilst maintaining the great quality that our customers love.
