air filters linked to improved cardiovascular health
Scientists believe that the use of cheap air filters may help reduce the risk of cardiovascular disease caused by exposure to air pollution.
Researchers from Canada studied healthy adults living in a small community in BC, where firewood stoves are the main source of pollution, and they found efficient granular Air (HEPA)
The filter reduces particulate matter in the air, thus improving vascular health and reducing blood markers associated with increased risk of cardiovascular disease.
The researchers recruited 45 adults from 25 families.
Monitoring the home of each participant twice in a row
HEPA filter during the day (
Honeywell model 50300)
HEPA filter in the main activity room and quieter (Honeywell 18150)
It was operated in the participant\'s bedroom.
HEPA filters operate normally during 7-1
During the day, there are no internal filters for other periods.
The order of filtering or not filtering
The filtration was random and participants did not know at which time the air was filtered.
Indoor pollution sampling equipment is placed in the main activity room of each family.
Participants were asked to record their activity, location and distance from the source of contamination every 60 minutes.
Of the 25 households participating in the study, 13 used stoves during the study.
In each 7-
Blood and urine samples were collected from each participant on a daily basis to measure cell damage markers and body response to damage.
The endothelial function was also evaluated using a fingertip device, blood volume of small vessels was assessed, and air samples were collected and analyzed.
After analyzing their data, the researchers found that the portable HEPA filter reduced the average concentration of fine particulate matter in the home by 60% and woodsmoke by 75%. a 9.
The reactive congestion index increased by 4%)

\"Our results support the assumption that systemic inflammation and impaired vascular endothelial function are both predictive factors of cardiovascular disease and can be positively affected by reduced particle concentrations and add to increasing evidence
\"Long-term exposure to particulate matter with systemic inflammatory response,\" said Ryan Allen, assistant professor at bennabee Simon Fraser University in BC.
