- Check that the neck/opening diameters of the reusable outer airless pump bottle and the replaceable inner insert match so that they fit securely together.
- Make sure the replaceable insert is absolutely clean and dry before inserting it. Any moisture can disrupt the airless vacuum seal.
- Fill the replaceable insert with the liquid or lotion of your choice. Fill to the maximum fill line, which is usually at the neck. Overfilling can make effective sealing impossible.
- Insert the filled inner container into the outer airless pump bottle and tighten the lid. To seal the vacuum, tighten the pump cap.
- Press down on the pump head to distribute. This will force the product out while preventing air from returning to the bottle.
- Pulling up on the pump head while the insert is still full with product can cause the airless vacuum mechanism to fail.
- Remove the empty insert and replace it with a new, clean one. Recapping and pumping with an empty insert may allow air to enter.
Palitan ang anumang mga insert na may mantsa, amoy, o may deformed. Ang mga di-kasakdalan sa insert ay maaaring pigilan ito mula sa epektibong pagbubuklod at pagpapanatili ng walang hangin na vacuum na kapaligiran.
