The Green Label Testing Program was introduced by CRI in 2000 for the purpose of identifying superior cleaning equipment. Three key performance factors are measured by a rigid testing process in order to determine if a vacuum qualifies for a Green Label. These factors are:
Soil Removal — A vacuum must remove a set amount of soil from a carpet in four passes.
Dust Containment — No more than 100 micrograms of dust particles per cubic meter of air by the vacuum. This protocol evaluates the total amount of dust particles released by the vacuum, and is more stringent than the National Ambient Air Quality Standards.
Carpet Appearance Retention — In one year of normal use, the vacuum should not affect the appearance of the carpet more than a one-step change.
The following vacuum cleaners have received the CRI Green Label Seal of Approval:
