Sometimes I see ads on TV for air cleaners. How do they rate?

They are good for only one room and then only the fan forced units. For more information see Consumer Reports February 2002 where they tested 16 different air purifiers, or a second article in October 2003. Honeywell produces whole house air cleaners that are far easier to care for than stand alone units. These systems work with your existing furnace and duct work. They are very high efficiency and will work with most existing systems. For more information you can contact our store.
