Short Summary

Main recommendation: Intermountain Medical Center is studying whether high-efficiency air filters placed in the bedrooms of high-risk people reduce particulates and symptoms during winter inversions, because the answer is not yet known. The study will recruit about 80 participants over two years, with each person serving as their own control.

Key Points

  • The study targets people at high risk for lung disease, such as former smokers, who become sick during poor air quality days.
  • Highest-efficiency filters usually cannot go on a furnace because their resistance is too high and could damage it, so they will be placed in bedrooms, where people spend the most time at home.
  • Researchers will measure particulates in the home, ask participants how they feel, and run breathing tests, including lung function tests, to check for measurable differences.
  • Each participant is their own control: the filter is on for part of the study and off for the other part, and symptoms are compared across inversion periods.
  • Dr. Blog notes that colds and flu complicate results in winter, which is why the team tracks actual particulate levels alongside symptom reports.

Details Worth Noting

  • Concrete instructions: Eligible people who think they may be good candidates should contact the study team by email at filter@imail.org or by phone at 801-507-4606. Participants keep the filter in their bedroom for about 12 weeks, with the filter switched on or off at the halfway point. Symptoms are reported over six-week periods for each side of the study. Dr. Blog mentions that people should get flu shots, since winter illness like colds and flu can complicate study results.
  • Device cost varies by filter quality and the room size it can cover, from about fifty dollars to several hundred dollars; the study aims to use the highest-efficiency single-room filters available.
  • Enrollment is planned at 40 subjects per year for about 80 total over two years, with each study period running from roughly mid-November through March to match inversion season.
  • Inversions generally last on the order of days, and exposure varies by time of day and whether people are at work or home, so the study design accounts for random fluctuation.
  • More information is expected on the Intermountain Medical Center website.

Bottom Line

The study will test whether a bedroom high-efficiency filter meaningfully lowers particulates and symptoms for high-risk people during winter inversions, and the video does not yet give a result.
