Tough standards for soil removal and indoor air quality

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/Green Label vacuum program, manufacturers must meet higher performance standards and are rewarded with Gold, Silver or Bronze ratings. This program tests two general categories of vacuums:

  • General-purpose vacuums approved for use on all conventional carpet styles
  • Vacuums specifically approved for use on carpet with a low pile, or surface texture, measuring approximately a quarter inch or less

To earn the CRI Seal of Approval/Green Label certification, vacuums must pass the following independent laboratory tests:

  • Soil removal — CRI uses NASA-enhanced x-ray fluorescence technology instead of traditional gravimetrix testing to measure the precise amount of soil removed from carpet — either 30 oz/sy commercial cut pile carpet or 30 oz/sy loop pile carpet.

  • Dust containment —  The vacuum must not release more than 100 micrograms of dust particles per cubic meter of air, keeping dirt and dust locked tight in the vacuum — not escaping back into the air where it can be breathed. Read More in CRI Test Method 113 PDF(PDF 156 KB) Need help with PDF?
  • Surface Appearance Change — The vacuum must not affect the texture of the commercial cut pile carpet (900 passes with sample rotated every 50 passes) more than a one-step change based on one year of normal vacuum use. Read More in CRI Test Method 114 PDF(PDF 46 KB) Need help with PDF?

Vacuum your way to cleaner carpet and cleaner air

Certified Space TechnologyHigh-performance vacuum cleaners have a significant impact on improved indoor air quality (IAQ). At the same time, vacuums that effectively remove and contain soil while keeping the carpet looking good will help carpet last longer. Ultimately, better performing vacuums provide a greater return on your investment and ensure a healthier indoor environment.

Use of CRI Seal of Approval/Green Label program assures proper and easy carpet maintenance. This important testing program has raised the performance bar for all vacuum cleaners on the market, resulting in cleaner, longer-lasting carpet and improved indoor air quality. So look for the Seal of Approval/Green Label logo or label on packaging, displays and on the machine itself.
