Indoor Air Quality Can Affect Sleep, but Filtration Is Only Part of the Fix

Jaspr founder Michael Feldstein argues that indoor air deserves attention because people breathe it continuously, including through the hours they spend sleeping. In a discussion with Chris Williamson, he says household sources such as cooking, fragrances and outdoor material tracked in on shoes can worsen air quality, while ventilation, source control and filtration address different parts of the problem. Feldstein recommends starting with low-cost changes at home, but says a purifier cannot substitute for fresh-air exchange or fixing a building problem.
