Ionizers are air purifiers that use electric charges to remove particles from the air. They are often used to reduce allergens, dust, and other pollutants in the home. But while they can be effective at eliminating certain particles, they can also have some negative side effects. Critics of ionizers argue that they emit dangerous levels of ozone, which can be hazardous to health when inhaled in high doses. Ozone is a lung irritant that can aggravate allergies and asthma, and can cause symptoms such as headaches, sore throats, coughs, and difficulty breathing. On the other hand, negative ions occur naturally and can have positive effects on humans, animals, and the environment.
They create oases of pure air that can improve health and well-being. In response to the COVID-19 pandemic, people have been installing ionizers in offices and restaurants. Laboratory tests have shown that ionizers can reduce particulate matter concentrations and lead to some improvements in the respiratory health of children. However, a recent study found that ionizers had an adverse effect on heart rate variability, meaning any benefit to the lungs came at a cost to the heart. When it comes to air purifiers, it's important to understand both the advantages and disadvantages of each type. While ionizers can be effective at removing certain particles from the air, they may also come with some risks.
It's important to weigh these risks against the potential benefits before making a decision.
