According to a recent study published in the journal Environmental Science & Technology, portable air filters that use HEPA (high-efficiency particulate air) filters can significantly reduce levels of particulate matter in indoor air.
The study, conducted by researchers at the University of Michigan, found that using a portable air filter reduced indoor particulate matter levels by an average of 55%. Particulate matter, a mixture of solid particles and liquid droplets found in the air, can have negative health effects, especially for people with respiratory conditions.
HEPA filters are designed to capture small particles, including many pollutants and allergens. The researchers found that the effectiveness of the air filter depended on the size and type of particulate matter in the air, as well as the airflow rate and the size of the room.
While the study focused on the effectiveness of portable air filters, the researchers noted that other interventions, such as improving ventilation and reducing sources of indoor air pollution, are also important for maintaining indoor air quality.
Overall, the study suggests that using a portable air filter with a HEPA filter can be an effective way to reduce indoor particulate matter levels and improve indoor air quality.
