Invisible particles in the air can be a cause for concern, as they can be inhaled deep into the lungs and cause health-related effects. These effects can range from eye and lung irritation to more serious issues such as cancer and decreased lung function. People who spend most of their time indoors, such as those with allergies or asthma, may be particularly affected by air pollutants in their homes. Air purifiers can help reduce these pollutants and improve overall health, but not all air purifiers are created equal.
When choosing an air purifier, it is important to consider the type of air purifier, the size of the interior space, the MERV rating, and how often you'll need to change the filter. Symptoms such as headaches, sore throats, coughs, asthma attacks, and difficulty breathing can be caused by some air purifiers. Fortunately, there are air purifiers that work as advertised and can improve health and well-being. Research has shown that HEPA air purifiers can reduce indoor toxins produced by 3D printers, although they are more effective if the filter is integrated into the printer itself.
The use of the best air purifiers has been linked to improved blood pressure levels and a 17% decrease in the fraction of exhaled nitrous oxide. In addition, HEPA filters are highly effective in eliminating fungi, mold and other allergens from indoor air. It is important to note that an air purifier removes polluting particles from the air, while a humidifier adds moisture particles to the air. Most household air purifiers contain HEPA filters, designed to capture all of these contaminants so you can breathe clean air.
However, the impact of air purification on airway inflammation and lung function remains controversial due to varying results depending on factors such as location and subject characteristics. When using an air purifier, it is best to place it where there is good airflow and where you think there is a high concentration of contaminants. Additionally, because of the design of some air purifiers, it may not be possible to determine whether or not they have filters based on their appearance.
