You will notice that we have changed the appearance of our Personal Oxygen Canister from what was formerly listed and pictured on this website. We have improved the product by providing twice the quantity of Oxygen than what was formerly available. There is now 4 Liters of Oxygen in each Canister which will provide 40-50 inhalations.

We accomplish this additional quantity in a similar size Canister by increasing the pressure at which we fill the Oxygen. Please note that the button will be more difficult to press the first few times it is used based upon this higher pressure. Please push the back part of the button to break the seal on the first use and then push the button at either the 3 o’clock or 9 o’clock position to overcome the greater pressure on the first few uses. After the pressure is reduced then the button will work easily with normal pressing in the center of button.
