There are many types of air quality products. The disposable types are media filters which are about 2% efficient and the pleated filters called the Farr® 30/30 which are 30% efficient and known as the best in the industry in collecting air borne particles. Then there are the electronic air cleaners known as the EAC although they are not disposable they still need to be maintained and cleaned every month.
