  • There are removable/interchangeable dividers for the 2.1-quart and 4-quart-sized rectangular containers. Each of these containers comes with 2 divider inserts.


  • 4. What function does the button on top of my Flavor-Lockers containers have?

  • This is the air release valve. It allows air to be removed from, and enter back into the Flavor-Lockers containers. Release vacuumed pressure by moving the air release valve to the side, until you see vacuum indicator pop-up.


  • 5. What purpose does the dial on the top of Flavor-Lockers containers serve?

  • This is the date recording dial. Simply rotate the slider to indicate the date you stored your food. This will help you monitor freshness.


  • 6. Why do I need to perform the NuWave Flavor-Lockers vacuum seal on containers when there are buckles present?

  • While Flavor-Lockers container buckles provide convenience and additional security, the buckles do not in and of themselves create or hold the seal. Consult your product manual for step-by step sealing instructions.


  • 7. May I use any kind of bags with Flavor-Lockers technology?

  • Flavor-Lockers have custom-made bags designed for use with the Hand and Auto Pumps. Please be advised that conventional freezer bags, or other types of bags, are NOT compatible for use with Flavor-Lockers vacuum seal technology.


  • 8. What is the benefit of the Fruit & Veggie Guard packets?

  • These packets are designed to decrease the presence of ethylene, a harmless, odor-free, colorless gas that exists in nature. As fruits and vegetables age, ethylene gas is released. The presence of this gas causes foods and plant materials to ripen or mature more quickly.

    When used in conjunction with Flavor-Lockers containers, Fruit & Veggie Guard packets can extend the shelf life of stored foods even longer. Your favorite produce can last weeks longer when stored with Fruit & Veggie Guards.


  • 9. What type of plastic is used to construct NuWave Flavor-Lockers containers? Are they BPA-free?

  • Flavor-Lockers are manufactured from BPA-free plastic. BPA is a chemical commonly used in the production of hard plastic food containers, and in the lining of metal food and beverage cans. Trace amounts of BPA can be found in certain foods packaged in these containers. While the Food and Drug Administration concluded in a 2008 study that food-related materials containing BPA were safe for use and consumption, recent studies have drawn attention to the effects of even low doses of BPA in laboratory animals.


  • 10. How do you know if the container has been vacuumed and sealed?

  • When you see the vacuum indicator compress, the vacuum process is complete.


  • 11. Are Flavor-Lockers products safe for use in a microwave or oven?

  • Flavor-Lockers containers are microwave-safe; the lids and bags should not be placed in the microwave as this will void the warranty. Although the containers are microwave-safe, we do not recommend microwaving them at high heat for an extended period of time. Always use caution when microwaving containers. Flavor-Lockers should never be placed in a conventional oven or a NuWave Oven.


  • 12. Will Flavor-Lockers discolor if I store things like sauces?

  • The material used in the production of Flavor-Lockers is stain-resistant and highly durable.


  • 13. How do I clean my NuWave Flavor-Lockers?

  • Flavor-Locker containers, lids and bags may be hand washed or run through a standard dishwasher cycle, using a low heat setting. When running your containers through the dishwasher cycle, place them on the top rack only. Seals and valves should be removed before washing to extend the durability of the silicone. They are removable and are easy to reassemble.


  • 14. What type of batteries are required for the Auto Pump?

  • The Auto Pump comes equipped with internal, fully rechargeable batteries. These batteries are recharged by plugging in the A/C adapter to any standard wall outlet. When the light turns solid red, the pump is fully charged.


  • 15. How long is the NuWave Flavor-Lockers warranty period?

  • The warranty is good for 1 year under normal use and only covers the Flavor-Lockers containers.


  • 16. Will Flavor-Lockers protect my valuables from the elements?

  • Under optimal conditions, when properly sealed, Flavor-Lockers do defend your foods, electronics and more from water seepage. However, as environmental conditions vary greatly from one location to another, damages incurred to foods and goods via saturation will not be covered under warranty. Hearthware assumes no responsibility for any loss or damage to items placed in Flavor-Lockers bags or containers. Consult your product manual for proper sealing instructions.
