The way that many buildings these days are constructed makes regular cleaning an absolutely essential part of any healthy home.Thanks to modern building practices that (rightfully) push for high energy efficiency, there's very little airflow transfer between indoor and outdoor environments. This means that a majority of the microscopic particles that manage to make their way inside our homes like allergens, mold spores, and mycotoxins, will remain there until they're actively removed. If you don't take steps to eliminate them, they'll continue to build up and reduce your indoor air quality.
