Summary
Neglected AC filters can recirculate dust, mold spores and other particles that irritate airways, triggering congestion, coughing and frequent nighttime wake-ups, Dr. Dale Christensen said.
90% of U.S. households use air conditioning, but Christensen said properly maintained systems have minimal air-quality impact; the problem arises when filters and ducts accumulate dust and moisture.
50% of homeowners have skipped AC maintenance to save money, according to the 2026 DuraPlas Summer Cooling Report, increasing the risk of indoor pollution and poorer sleep quality.
CDC guidance cited in the report says AC filters should be replaced every three months; Christensen also recommended better ventilation and limiting fragrances, aerosols and other high-VOC products.
