What’s In Your Air?

Elevate Your Air Quality IQ





Particle Pollution


Enter a location to discover the air quality.



The Air Quality Index (AQI) is calculated by individually weighing 6 key pollutants (PM10, PM2.5, O3, NO2, SO2, CO) in a formula. Each pollutant has both a concentration value and AQI value. The formula is intended to translate what can be a confusing concentration measurement of air pollutants into one simple scale that shows a comparable level of health risk across all pollutants. Whichever individual pollutant is at the most 'risky' concentration (highest AQI number) dictates the overall AQI.

The United States Environmental Protection Agency has developed guidelines, thresholds and a color scheme for the Air Quality Index (AQI). The AQI is a system that translates unintuitive pollutant concentration measurements into one easy-to-understand scale to clearly represent the health risk posed by ambient air pollution. The index ranges from 0 to 500, where high index values indicate higher levels of air pollution and higher potential for adverse health effects. There are two systems - one in the United States and one in China - but since the American index system yields higher scores for AQI’s under 200, and thus is considered to be more strenuous, the U.S. index has become the general global standard.

Range Color Detail Recommendations
0 to 50 Good Air quality is satisfactory and poses little or no health risk. Ventilating your home is recommended. Enjoy your usual outdoor activities. We recommend opening your windows and ventilating your home to bring in fresh, oxygen-rich air.
51 to 100 Moderate Air quality is acceptable and poses little health risk. Sensitive groups may experience mild adverse effects and should limit prolonged outdoor exposure. Enjoy your usual outdoor activities. We recommend opening your windows and ventilating your home to bring in fresh, oxygen-rich air.
101 to 150 Unhealthy for Sensitive Group Air quality poses increased likelihood of respiratory symptoms in sensitive individuals while the general public might only feel slight irritation. Both groups should reduce their outdoor activity. The general public should greatly reduce outdoor exertion. Sensitive groups should avoid all outdoor activity. Everyone should take care to wear a pollution mask. Ventilation is discouraged. Air purifiers should be turned on.
151 to 200 Unhealthy Air quality is deemed unhealthy and may cause increased aggravation of the heart and lungs. Sensitive groups are at high risk to experience adverse health effects of air pollution. Outdoor exertion, particularly for sensitive groups, should be limited. Everyone should take care to wear a pollution mask. Ventilation is not recommended. Air purifiers should be turned on if indoor air quality is unhealthy.
201 to 300 Very Unhealthy Air quality is deemed unhealthy and may cause increased aggravation of the heart and lungs. Sensitive groups are at high risk to experience adverse health effects of air pollution. The general public should greatly reduce outdoor exertion. Sensitive groups should avoid all outdoor activity. Everyone should take care to wear a pollution mask. Ventilation is discouraged. Air purifiers should be turned on.
301 to 500 Hazardous Air quality is deemed toxic and poses serious risk to the heart and lungs. Everyone should avoid all outdoor exertion. The general public should avoid outdoor exertion. Everyone should take care to wear a quality pollution mask. Ventilation is discouraged. Homes should be sealed and air purifiers turned on.
**Sensitive groups include children, elderly and pregnant people or those suffering from cardiac or pulmonary diseases.

The main pollutant in AQI is most often PM2.5 due to its prevalence and risk for harm. However, sometimes, in hot summer months for example, Ozone (O3) will be the main pollutant. In particularly sandy or dusty locations, PM10 will often be the main pollutant. The main pollutant dictates the AQI curve, and calculation.

Here are a few reasons...

1) Air pollution is the 4th highest cause of death worldwide after high blood pressure, diet and smoking, and the greatest environmental health risk.
2) More than 95% of the world's population breathes dangerous air.
3) While China and India account for more than half of its death toll, air pollution harms rich, industrialized countries. Eight of 2017’s 10 most polluted cities in the U.S. concede Ozone (O3) is an urgent health threat.

What Is Recreational Oxygen In A Can?

Lauren Carlstrom, O+ Team Member |  Pioneered in 2003 by Oxygen Plus, the growing category of portable recreational oxygen has several unique and differentiating characteristics from medical or other supplemental oxygen. Oxygen Plus was recently named a “major player…involved in R&D activities for the development of cutting edge products” in a global recreational oxygen equipment market that’s expected to grow at a CAGR of ~16.3% from 2019 to 2026, reaching a market value of ~$307 million by 2026 (Acumen Research and Consulting). But what are some defining features of recreational oxygen canisters themselves? And what are some reasons Oxygen Plus just may be the #1 most trusted recreational oxygen company in the world?

Recreational Oxygen Canisters: The Next Bottled Water?

Lauren Carlstrom, O+ Team Member |  If you caught wind of questions about recreational oxygen in a can on ABC’s Shark Tank, you may have a few questions of your own. What did the Sharks think of this company’s oxygen product? Well, no Shark challenged the statement it was the next bottled water. I’m up for that challenge, and will share a few thoughts below. But one thing is clear: This industry has legs. The company mentioned it wanted to grow their retail business – taking it direct, moving away from their current distribution system that utilizes distributors and brokers. Very different from that company but similar in product category, Oxygen Plus – the pioneer of lightweight recreational oxygen, with an estimated 30%...

Trailblazing a New Travel Buddy: Face Masks

Lauren Carlstrom, O+ Team Member |  Joining the travel trend of the Fourth of July weekend, I was among an estimated 48.9 million Americans who helped mark the largest number of U.S. travelers on record for the holiday (Hall). Exposed to new sights, smells and sounds, my journey Westward to San Francisco, California had some thrilling, and some chilling, experiences that caused me to rethink how I might chose to travel. SF’s Chinatown, to which many Chinese immigrants were first drawn for better economic opportunities and the gold rush of the 1850s, is a part of a second national influx of Chinese-American immigration. It was in this lively “city within a city” that an ever-increasingly common image – a person...

The Breath: When in doubt, "Stay in your nose.”

Charles J. Meakin MD, MHA,  O+ Wellness Contributor | My lifelong hobby of high-performance and holistic living strategies, coupled by my 30 years of providing medical care in the Cancer Center, has taught me that the Breath is our top health priority and Oxygen is our most crucial nutrient. Proper breathing improves our immediate well-being and may add years of functional longevity. Surprisingly, despite the importance of oxygen delivery and release of carbon dioxide, this exchange is frequently overlooked in healthcare discussions. Most of us are habitual mouth breathers (look around), we now have indoor air pollution, and many American cities  have diminished percent oxygen levels to the high teens (18 percent while historical normal is 21 percent oxygen in the air)...

O+ Office Plants, Meet Air Pollution!

Lauren Carlstrom, O+ Team Member | We recently moved Oxygen Plus’s worldwide headquarters, and thus, had the chance to redesign our office layout and overall look and feel. It didn’t take long to pick the wall colors: Gray and yellow – colors that align with our brand and evoke a sense of a calming balance and productive optimism, respectively. It also wasn’t hard to make the decision to dedicate an entire room to what’s called, the “O+ Relaxation Room” – a concept inspired by Arianna Huffington. O+ team members can take a breather with or without our options of supplemental oxygen machines throughout the workday. Sometimes I take a moment to rest my eyes while listening to the waves of...

Oxygen Plus: The Next Level of Hockey

Lauren Carlstrom, O+ Team Member |  An authentic Minnesota gal, I traded in my ballet shoes for a pair of hockey skates in high school. While I never mastered a left-sided hockey stop like I did my double pirouette, I did manage to win the “most improved player” award after my first year on the ice. Watching hockey today, armed with a bit of knowledge about how oxygen helps improve performance and recovery in sports, I’m struck by how many of today’s professional and amateur hockey players, and their trainers and coaches, are missing out on what could be a major advantage: Oxygen Plus (O+) pure recreational oxygen. Oxygen and Hockey – A Brief Explanation of the Connection Oxygen Plus...

Get Pollution Out Of Your Face!

Lauren Carlstrom, O+ Team Member |  Pollution is not only an environmental threat that affects our breathing and overall health. It’s also a hazard to that youthful glow. The beauty and skin care industries are meeting the need of a growing group of consumers who are concerned about how air pollution affects their skin and “beauty.” More so for health reasons, people need to learn about the damage of air pollution faster than the lion’s share of consumers caught on about the need for sun protection. It took consumers more than 30 years to really make the connection between skin damage and UV rays (Stevenson). Our largest organ, our skin, takes a beating when air quality is compromised. It’s no...

Pick Up Some Butts!

Lauren Carlstrom, O+ Team Member |  A bus stop billboard caught my eye the other day. It was an advertisement for screening/tests for people who had successfully quit smoking cigarettes. The image of a woman, standing on an impressive mountain of cigarette butts, spoke volumes: Every little cigarette adds up. In fact, in a world where ten million cigarettes are purchased a minute, the number of toxic-filled cigarettes smoked – and discarded – each year is in the trillions, and the number of cigarette butts trashed annually (~5 trillion) weighs ~2 billion pounds. Surveying the streets beneath my boots – speckled by culturally-accepted, semi- innocuous cigarette butts – I now wondered how much, and in what ways, those cigarette butts, and the...

Who Can Steal Your Oxygen?

Lauren Carlstrom, O+ Team Member | The times may be, or appear, divisive. Yet we may agree on the point that we all share the same air, and atmosphere. It may surprise you just how interconnected the air we breathe really is. Consider the breaths you inhale each day from an astrophysicist’s perspective. In his book, Astrophysics for People in a Hurry, scientist Neil de Grasse Tyson writes, “A single breathful draws in more air molecules than there are breathfuls of air in Earth’s entire atmosphere.” Selah! (Pause and think about that)! That means we have to share – and can’t steal – each other’s oxygen, not even when we’re in the same room or Twittersphere. The physical properties of...

The Air of Our Children

Lauren Carlstrom, O+ Team Member | I had the privilege of witnessing my brother’s first baby-boy’s baptism this weekend. As the minister plunged the baby’s wiggly head under the trickling water, I caught his little nose seeking a breath of air. I feel fortunate that my nephew and nieces will grow up in a city that is known for its 10,000 plus lakes and environmental progressiveness. However, I am saddened that many lovely children – who live in both impoverished and industrialized nations – will not have ready access to clean air. The World Health Organization recently reported that 3 million people a year die from air pollution – that’s more than Malaria and HIV/Aids deaths combined! And while more...

A New York Breath

Lauren Carlstrom, O+ Team Member | As a New Yorker, I appreciate Oxygen Plus (O+) because I know – and can be in control of – what's going into my lungs. Living in the tenth most polluted metro area in the U.S., even a quick walk with the dog can leave me coughing and gasping for a breath of fresh air (Rice). Just today, I turned a corner with my pup, only to be greeted by a big cloud of second-hand cigarette smoke. Next, the taste and smell of a building renovation viscerally coated the inside of my mouth. To top off our walk, several large trucks whizzed by spouting out black exhaust fumes. And I felt terrible. Knowing that...

Be Aware of the Air You Breathe: Our Air Pollution Crisis

Lauren Carlstrom, O+ Team Member | The air we breathe: It’s invisible, but it can be poisonous, dangerous, even deadly. Plus, air pollution and poor air quality is a bigger problem than you may believe – affecting the majority of the world’s population both indoors and outdoors. This alarming reality should arose you to a state of anger – and moreover, into a place of taking action. First, Know Your Air Perhaps the initial step in working toward curtailing air pollution is to assess the current state of the air we breathe. We have to know what’s out there – in our atmosphere. Here is a brief rundown of the facts, sourced from a recent article in The Guardian (Harvey)...

Commute by Subway? Grab Your Oxygen Plus!

Lauren Carlstrom, O+ Team Member | It is estimated that, worldwide, there are more than 120 million people who commute daily (Amato). The demand and need for public transportation continues as people move to larger cities. Typically affordable and convenient in expensive metropolitan areas like New York, Chicago, San Francisco and Toronto, commuting by train or subway is part of many city-dweller’s daily grind.   In addition to providing convenience and an affordable means of transportation, subways pay a vital part in urbanization by reducing air pollution and traffic in larger cities. While the reduction of air pollution is a positive outcome, one ironic aspect of commuting by subway that is causing concern – and researchers to actively study –...

What Cigarette Smokers and Those Who Live in Polluted Cities Both Need: Pure Oxygen

Lauren Carlstrom, O+ Team Member | As you learn from an early age, oxygen is an essential component of life and living. Humans, and of course even the dogs we love, breathe the oxygen available in ambient air to thrive and function. But what happens when your body does not get sufficient oxygen through the air you breathe? Or what happens when the air you’re breathing has been compromised or contaminated? Air pollution and cigarette smoking add additional toxins to the air that’s inhaled, so a smoker or someone living in a polluted city may not get optimal levels of oxygen on a regular basis. In addition to experiencing an on-going, long-term oxygen debt, the effects of sub-par oxygen levels...

Why Oxygen Plus is the Air Apparent to Energy Shots, Drinks and Supplements

Andre Peschong and Lauren Carlstrom, O+ Team Members | Oxygen Plus is a healthier alternative to “energy” shots, energy drinks and energy supplements because O+ oxygen is completely natural, side-effect free, and has a wider range of practical applications. Don't reach for the chemicals or suffer from unwanted side-effects before you try the simple solution first - more oxygen. Oxygen uptake is directly related to health and performance. Insufficient oxygen in the blood, called hypoxia, can lead to lightheadedness, fatigue, lactic acid buildup, and in more extreme cases, headaches, tingling of extremities, nausea, confusion and disorientation. The causes of insufficient oxygen uptake, sometimes called an oxygen debt, include changes in altitude, environmental factors like smoking cigarettes and air pollution, vigorous...
