Discussion: COPD patients should replace carpets from floor to floor with other floorings.

Carpets are an excellent incubator for dust mites, a potent allergen for most respiratory disease patients. The use of chemicals is not desirable. The alternative (which requires constant care) is ongoing disinfection in a robust industrial steam appliance. COPD patients are advised not to sleep in rooms with carpeted floors.
