How does O+ define a breath and a "deep" breath?
We generously define an O+ breath or a "deep" breath as equaling approximately a second and a half. The way other recreational canned oxygen companies define a breath varies. Some define a breath as one second long. So, keep this in mind if you're shopping for oxygen products with the most "breaths for your buck" - a little term affectionately coined by our Founder. You might be interested to know an accurate way to compare products is to look at the price per liters (litres) in a can.

What does "portable" oxygen mean?
O+ products can easily fit in a purse, pack or briefcase with room to spare. Whether in a bar, the subway or in a stale office environment with poor air quality, the portability of O+ products offers the convenience of a sleek design that travels with you.

How often can I use O+ products?
O+ can be used every day. However, O+ products are for recreational, intermittent use only. Prolonged use is defined as uninterrupted intake for more than 8 hours. WARNING: Persons with any type of health or medical condition should consult their physician prior to use of products.

How long does it last?
The benefits of supplemental oxygen have varying durations, depending on the individual and the benefit. The feeling of alertness and mental clarity has been shown to last several minutes. Often the "feelings" of using supplemental oxygen depend on what you're doing, your starting blood oxygen level, and how well you are breathing, among other things. 

How do I know it's working?
Each person's response to breathing enriched oxygen will be different. After a few breaths, you should feel invigorated -- either a mental or physical boost or a sense of calm. If you were to ascend to an elevation 3,000 feet or higher than your normal elevation, the effect of breathing O+ would be more noticeable, both physically and mentally.

What research is available regarding the use of supplemental oxygen?
Good question. Check out oxygen research to learn about the science behind the benefits of breathing enriched oxygen.

Can O+ products help me in higher altitudes such as mountain elevations?
Although the concentration of oxygen in the atmosphere is uniform at all elevations, lower barometric pressures at higher altitudes allow all molecules in the air to expand so each breath contains fewer oxygen molecules. The larger molecule problem can be counteracted by increasing the oxygen concentration of the air you breathe or by acclimatizing to the higher elevation over a period of weeks. Not being acclimatized can result in shortness of breath during exertion, hyperventilation, and more. During use, O+ products can supply a higher concentration of oxygen that simulates being at lower altitude.

Is it safe?
O+ is safe for healthy people of all ages when using the product as directed. It is recommended children use only with adult supervision. People with impaired heart or lung function or other medical conditions should consult with their physician prior to using O+ products. O+ products are for recreational, intermittent use only. Prolonged use is defined as uninterrupted intake for more than 8 hours. Legal has more to say about the intended use and precautions for O+ products.

Are there any side effects?
There are no side effects when O+ products are used as directed.

Is it FDA approved?
O+ is a recreational product intended solely for intermittent use. (Prolonged use is defined as uninterrupted intake for more than 8 hours). Since O+ is not a medical product or intended for medical use, it is neither regulated nor approved by the FDA. However, the aromas, scents or flavors in O+ products are food- and beverage-grade flavors approved for use by the FDA and the Food Extract Manufacturing Association.

Could I use O+ products in an emergency situation such as a fire?
Not advised. Although oxygen gas is non-flammable, it accelerates fire and flames. In case you're wondering, the cylinders worn by firefighters contain normal air.
