EPA studies indicate, that the air in your home may contain up to 10 times more pollutants than the air outdoors.
A standard 1″ disposable air filter, is only designed to catch large particles. While this is great for protecting your HVAC equipment, it does nothing to improve the air quality in your home.
A high efficiency media air cleaner, equipped with a disposable air filter rated at MERV 8 or higher, is a far superior choice. They are 5 to 10 times more efficient than a standard 1″ filter, and usually only require one filter change per year.
