1. You can use a common vacuum cleaner or air pump to remove air from the bag. Point the nozzle at the valve and start pumping. Once all the air is sucked out, quickly pull out the nozzle and replace the valve cap, securing it firmly.
2. If storing a large, thick quilt, the air removal process will take longer. You don't need to finish pumping it all out at once. If you need to stop, tighten the air valve to prevent air from entering.
3. Remember to finish your current task or take a break before continuing to pump. Always replace the valve cap after pumping.
