What are whole-house air cleaners?
Whole-house air cleaners may be used if your home is heated or air-conditioned through ducts. With a whole-house air cleaner, HVAC system includes air filters designed to reduce the accumulation of dust and dirt in the ducts and coils of the system. These simple filters cost less than a dollar each to replace every month or two, but they only remove large particles, not the small particles in the house that are inhaled into the lungs.
