S-fresh® Vacuum Cleaner Air Freshener sachets deodorise your home as you vacuum, so your home is fragrant as well as clean. Simply open the sachet, scatter the scented granules on the floor and vacuum them up. For bagged vacuum cleaners, just insert granules in the vacuum bag. We recommend using one scented sachet each time you change the bag or empty the dust compartment of your vacuum cleaner. This pack contains 18 sachets.
