CRI approved Vacuum Cleaners

	Have good soil removal
	Keep dust in the machine and bag, out of the air
	Keep carpet looking good

Look for the CRI Indoor Air Quality Label

Vacuum Cleaner Indoor Air Quality Testing Program
To help protect the indoor air quality in your home, keep all indoor surfaces as clean as possible by vacuum cleaning -- without putting dust back into the air.

This IAQ program identifies vacuum cleaners that do each of three tasks well:

	Removes soil
	Contains dust within the filtration bag and the machine itself, keeping it out of the air
	Doesn’t damage the carpet and helps keep its appearance looking good.

Look for the CRI indoor air quality label on approved machine packaging and merchandising displays. In addition the manufacturer may place a logo on the machine itself.

Good Vacuum Cleaner Practices
Follow the vacuum cleaner manufacturer’s instructions for proper use of their product. For the best cleaning results, inspect the vacuum cleaner periodically to be sure it is functioning properly:

	Keep brushes clean, and replace them when worn.
	Keep vacuum hoses and attachments free of obstructions that restrict air flow.
	Inspect belts frequently to make certain they are working properly.
	Always keep a spare belt for replacement as needed.
	Follow the vacuum cleaner manufacturer’s instructions, and change the vacuum bag when it is more than half full. As the bag becomes full, soil removal efficiency is reduced.
	Use original equipment manufacturer (OEM) replacement bags or bag types recommended by the vacuum cleaner manufacturer.

The following CRI Logo may be permanently placed on authorized vacuum cleaners.

Vacuum Cleaner IAQ Testing Program Label

Carpet Industry Standard
The tests follow a procedure that has been developed by carpet manufacturers and vacuum cleaner manufacturers and peer reviewed by scientists who are respected for their expertise in the study of maintenance and indoor air quality.

Soil Removal – The soil removal test protocol requires that the vacuum cleaner must remove in 4 passes a satisfactory quantity of soil from the standard test carpet.

Dust Containment – The dust containment test protocol evaluates the total amount of dust particles released into the surrounding air by the action of the brush rolls, through the filtration bag, and any air leaks from the vacuum cleaner system. This protocol requires that a vacuum cleaner will release into the surrounding environment no more than 100 micrograms of dust particles per cubic meter of air, well below levels stated in the National Ambient Air Quality Standards.

Carpet Appearance Retention – The test protocol for appearance retention requires that the vacuum cleaner should affect the appearance of the carpet no more than a one-step change, based on one year of normal vacuum use.

Vacuum cleaners must meet all three elements of the Standard in order to obtain authorization to display the official CRI Indoor Air Quality Testing Program Label or CRI Logo.
