Allentown tops the 2026 Asthma Capitals list, and the report points to older homes, indoor air and traffic pollution. Here are the household cleaning habits that reduce dust, and where cleaning stops and a doctor starts.
Living in the Lehigh Valley with asthma or allergies means thinking about indoor air in a way that most people elsewhere do not. Cleaning is not medicine, and nothing here replaces advice from your doctor. It can, however, reduce the dust and residue that sit on surfaces in your home.
This guide looks at what the local report says, and at the routines most likely to help.
The Asthma and Allergy Foundation of America placed Allentown first in its 2026 Asthma Capitals report, a position it also held in 2021, 2023 and 2024. The report notes that nearly 40 percent of Allentown homes were built in 1939 or earlier and names indoor air quality, including mold and mildew, as a local concern.
It also looks outside. AAFA gives the valley a failing grade for high particle pollution days and notes that Allentown sits along the busy I-78 and Route 22 corridors. Census figures back up the housing picture, with 37.9 percent of Allentown's units from 1939 or earlier and many of them attached.
The report is about asthma, and its details concern a city, not your particular home. But it does explain why dust control comes up so often in conversations about keeping a house here.
If you can only do one room well, do the one where people sleep. It is where most people spend the longest unbroken stretch of each day.
Older homes tend to have more places for dust to rest, such as tall baseboards, trim, radiators and stair rails. Work from the top down so that whatever falls lands on floors you have yet to do. Wipe registers and vents. In a house built before 1978, take care around chipping paint and ask a qualified person about it, since scrubbing or dry sanding would make matters worse.
A One-Time Deep Clean can give you a clean starting point, with ceiling fans and vents wiped in place, blinds wet-wiped and window tracks cleared. A Recurring House Clean then keeps dust from returning to the old level. Weekly or bi-weekly tends to suit a home where someone is sensitive to dust.
Near I-78 or Route 22, windows and tracks may collect more fine grime. Wipe them more often, and ask your doctor or local air quality alerts about when to keep windows shut.
AAFA names mold and mildew among Allentown's indoor concerns, and local weather does not help. A normal year brings 47.36 inches of precipitation across about 81 wet days, with July the wettest and warmest month. Run bath fans, let shower stalls dry, and clean surface mildew from tile and caulk before it spreads.
Know where cleaning stops. Growth that keeps returning, covers a large area or comes with a musty smell points to a moisture source. TotalCare Cleaning does not provide mold or water damage remediation, so a specialist needs to handle those problems.
Stink bugs gather on houses on warm fall days and can enter in large numbers. Penn State Extension advises using a vacuum to remove live and dead ones indoors, and says using insecticide inside is not advisable, which is useful advice for a house where someone has breathing trouble. Empty the vacuum outside, since their smell can stay with it.
