Earlier we discussed that the “Green” carpets certified by the Carpet and Rug Institute (CRI) are marked with a Green Label, this is also true for vacuums. CRI certified vacuum machines improve the cleanliness of your carpet and the quality of your indoor air. The CRI vacuums remove allergens and dust that become trapped in the carpet fibers.
The CRI combines the indoor air quality of its Green Label and cleaning standards of its Seal of Approval program to identify even better performing vacuum cleaners. Under the enhanced Seal of Approval vacuum program, manufactures are held to a higher standard of performance and are rewarded with Gold, Silver, or Bronze ratings.
CRI employs an independent testing laboratory to measure:
- Soil removal — A machine’s performance in soil removal is measured precisely through NASA-enhanced X-ray fluorescence (XRF) technology. The entry level of Bronze requires a 10 percent improvement of soil removal over the Green Label program and the standards are even higher for Silver and Gold levels.
- Dust containment — A residential vacuum must not release more than 100 micrograms of dust particles per cubic meter of air. You want all that dirt, dust and pet dander locked tight in the vacuum, not escaping back into the air where it can be inhaled. Additionally, Gold level vacuums must meet ambient air quality standards.
- Carpet fiber protection — The vacuum must not affect the appearance of the carpet more than a one-step change (shop speak for “not very much”) based on one year of normal vacuum use.
Before being considered for the Bronze, Silver or Gold Seal of Approval ratings, a vacuum cleaner must comply with the carpet fiber protection standard as well as meet both the corresponding soil removal standard and dust containment The CRI Seal of Approval program makes vacuum cleaner selection easier for you. So look for the Seal of Approval logo or label on packaging, displays and on the machine itself.
