An Effective Way to Get Fresh Oxygen at Home: The Unique Experience of Entrepreneur Ilia Klimkov

Did you know that a person can survive 30 to 50 days without food, about 10 days without water, but only 7 minutes without air? That’s why, especially now—when urban pollution in major U.S. cities is a growing concern—the issue of providing the body with high-quality oxygen has become more relevant than ever.

In the past, oxygen therapy was associated with alpine resorts or specialized medical facilities. Today, however, access to this vital substance is available right in your own home. But how?

Journalists from Discover Health explored this question in a conversation with Ilia Klimkov, a new-generation entrepreneur and the founder of the innovative wellness project OXYFIT.

Oxygen: not a medication, but a basic human need

When we don’t get enough air, we instinctively feel that something’s wrong—yet we often dismiss the signs. Mild shortness of breath (first during exercise, later even while walking or at rest), a sense of shallow breathing despite open windows, and fatigue that turns everyday tasks into overwhelming challenges are usually blamed on stress or a long workday.

We often ignore headaches as well, though they’re another warning sign from the body that it’s running low on oxygen. This condition is known in medicine as hypoxia—a state in which oxygen levels in the body or specific organs and tissues fall below normal.

Oxygen deficiency Is a serious risk

“The brain is the primary consumer of oxygen, so it’s the first to suffer when levels drop,” says Ilia Klimkov, founder of the wellness brand OXYFIT. “When the brain isn’t breathing deeply, a person becomes scattered, concentration drops, and memory problems start to appear.”

Behavioral changes are also common—from lethargy and apathy to irritability and anxiety. This often leads to sleep disturbances: falling asleep becomes difficult, rest is not refreshing, and frequent awakenings leave people exhausted despite a full night in bed.

Oxygen deprivation also affects physical appearance: skin turns pale, lips and nails may appear bluish, and the heart beats faster as the body tries to deliver more oxygen to the tissues. People may experience unexplained sweating or a sensation of tightness in the throat—factors that only increase feelings of anxiety.

What to do if you have hypoxia

“Today there are effective oxygenation methods that allow you to restore oxygen levels without leaving home,” Klimkov says, noting the examples set by Scandinavian countries and Japan, where at-home oxygenation is already part of a healthy lifestyle.

What is home oxygenation?

Home oxygenation is a practical method of enriching the body with oxygen in the comfort of your own space. Ilia Klimkov launched an online store on Shopify in early 2023, offering specialized breathing trainers designed for this purpose.

“Paired with oxygen concentrators, these trainers are powerful tools for recovery and health support—especially for older adults and young children,” Klimkov explains. “They’re also essential for anyone leading an active lifestyle or engaging in sports.”

What are breathing trainers?

Breathing trainers are simple yet highly effective devices for health restoration and maintenance. Their benefits go far beyond physical therapy—they positively affect the lungs, heart, brain, and overall well-being. “Especially in urban environments, where physical activity is low and the air is polluted, training your breath isn’t just helpful—it’s essential,” says Klimkov.

The core function of a breathing trainer is to create controlled resistance during inhalation or exhalation, forcing the respiratory muscles—including the diaphragm—to work harder. This increases lung endurance, expands breathing volume, and improves the exchange of oxygen and carbon dioxide in the blood.

“After just a few weeks of regular practice, many users report that breathing becomes easier, energy levels rise, and mood improves,” Klimkov notes.

But the impact of breathing trainers extends beyond the respiratory system. With more oxygen entering the body, all organs begin functioning more efficiently. The brain receives better nourishment, cognitive focus and memory sharpen, and anxiety decreases. The cardiovascular system responds as well: blood pressure lowers, vascular tone improves, and the sensation of tightness in the chest fades.

Breathing trainers are especially valuable during recovery from illnesses involving lung weakness—such as COVID-19, pneumonia, or bronchitis. They help users regain control over their breathing and return more quickly to their usual rhythm of life.

According to Klimkov, one of the biggest advantages of breathing trainers is their accessibility. No special medical training is required—just follow the instructions and practice regularly. And the results—deep, free breathing, and an overall improvement in quality of life—come quickly.

“Health problems often start with simple stress and oxygen deficiency. That’s why breathing trainers are a powerful ally in both physical and mental recovery,” says OXYFIT founder Ilia Klimkov.

Who is Ilia Klimkov?

An innovative entrepreneur based in San Diego, Ilia Klimkov is known for his unique approach to e-commerce: he promotes products without spending a dime on marketing and builds his inventory around current consumer demands.

In early 2023, amid growing public concern about air quality and the health effects of hypoxia, Klimkov not only launched the wellness brand OXYFIT, but also developed an entire ecosystem centered around the idea of home oxygenation.

“The mission of OXYFIT is to give every individual the opportunity to restore their oxygen balance without leaving home or undergoing costly medical procedures,” Klimkov explains. He emphasizes that oxygen therapy should not only be used as a treatment, but also as a preventative health measure.

“Oxygen isn’t medicine—it’s a basic human need that’s still underappreciated. But I’m convinced that home oxygen generation isn’t just a passing trend—it’s a new norm that will only grow stronger in the years ahead,” says Klimkov.

To conclude, home oxygenation and breathing trainers are far more than just a way to “breathe deeper”—they’re the foundation of a new self-care culture. What once seemed exotic is now accessible, and everyone can experience its benefits and make it a part of daily life.
