Cleaner carpets and cleaner air

CRI Seal of ApprovalThere is one simple step to improving the cleanliness of your carpet and the indoor air quality in your home: regular vacuuming with a CRI-certified machine.

Carpet fibers serve as a trap for allergens and other particles, reducing their continued circulation in the air. Removing them with a CRI-certified vacuum effectively sucks up the dust from the carpet, locks it in the machine and keeps it out of the air. At the same time, vacuums that effectively remove and contain soil will help carpets last longer and keep them looking great.

Tough standards for soil removal and indoor air quality

CRI Seal of Approval Labels

CRI combines the indoor air quality protection of its Green Label vacuum program with enhanced cleaning standards of its Seal of Approval programs to identify even better performing vacuum cleaners than the previous program. Under the Seal of Approval vacuum program, manufacturers must meet higher performance standards 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 more soil removed, the higher the rating. Read More in CRI Test Method 112 PDF(PDF 114 KB) Need help with PDF?
  • 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. Read More in CRI Test Method 113 PDF(PDF 156 KB) Need help with PDF?
  • Surface Appearance Change — 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. Read More in CRI Test Method 114 PDF(PDF 46 KB) Need help with PDF?

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.
