Listed here is a home oxygen concentrater machine that delivers 93±3% pure oxygen concentration. NASA proposed at least 15 indoor plants which clean the IAQ (indoor air quality) but with modern pollution, consumer products like cleaners that release VOCs, unmaintained HVAC units, dirty ventilation, dirty plumbing etc it is inevitable that most indoor households have poor air quality which is a verifiable contributing factor to health problems. Common Low oxygen (hypoxia) symptoms include: fatigue, weakness, coughing, shortness of breath. Without adequate oxygen in the human body, organ functions depreciate. This Unit will increase indoor oxygen levels safely. For personal intranasal administration, all customers must consult their healthcare provider first, as oxygen can be a dangerous gas especially at toxic levels and highly volatile around flammables like candles or cigarettes or fireplaces or anything that can ignite a spark.
