Frequently Asked Questions

Are these bags really smell proof?

Yes, Kovert bags are actually smell proof! Our advanced 5-layer technology ensures odors from the contents of your Kovert bag are undetectable.

How do smell proof bags work?

We use activated carbon to trap in any unwanted scents and 4 additional layers of smell protection to ensure the contents are undetectable. Activated carbon is a type of charcoal that’s treated with oxygen to open up millions of tiny pores between the carbon atoms. This dramatically increases the surface area of the charcoal, which allows it to attach itself to more molecules of gas, including the ones that cause smells. Whatever’s causing the odor is then trapped in the pores of the activated carbon, keeping scents trapped in the lining of the bag.

How do I use smell proof bags?

The bags are easy to use; simply place your item in the bag and seal it shut. The airtight seal will prevent any odors from escaping, ensuring that your privacy is protected and no one will be able to tell what’s inside.

How do I set the lock combination on my bag?

Instructions

  1. Set lock to the current combination. The factory default is 0-0-0.
  2. Press down the reset button until you hear a “click”. You may need a pin tool.
  3. Set your new lock combination.
  4. Press to open and set your new combination.

Do Kovert smell proof bags block smell from dogs?

Our patented smell-proof bag technology is mainly designed to protect scents from the bag’s contents from detection by human noses. We’ve tested our bags with dogs, and they’re good enough to conceal chocolate from your chow chow! But dogs’ noses are very sensitive, so don’t rely only on Kovert smell proof bags to go KO with a K9. If you need extra protection, you can place your items in one of our disposable zip lock bags before placing it in your main bag.

How do I refresh the carbon filter lining in my bag?

You can reactivate the carbon filter by putting it outside with exposure to direct sunlight for one hour. Since the UV rays from the sun kill bacteria, this will remove any trapped odors and make your bag smell fresh again. Afterwards, you can put the bag back to use as usual.

If it’s a cloudy day or you don’t have a way to sun your bag, 20 minutes of heat from a hair dryer or clothes dryer will also remove smells from your bag. If you’re using a hair dryer, be sure to keep the setting on low and hold the dryer about six inches away from your fabric. This will remove unwanted smells and kill bacteria.

Clothes dryers typically have a higher heat setting than hair dryers, so you’ll need to be careful not to overdo it. 20 minutes of heat should be enough to freshen up the filter without damaging the bag so it can last as long as possible. After you’ve ensured that your bag is fresh and clean, you can use our smell-proof bags with confidence that your privacy is protected.

Do you make custom bags?

What are smell proof bags made of?

Our smell proof bags are made from high-quality materials that are designed to withstand daily use so that people of all tastes can have the level of privacy that they deserve. We use 2 layers of filterable non-woven fabric cover an inner layer of activated carbon. A durable water resistant outer fabric protects your contents from harsh weather and the elements. An inner protective polyester mesh lining and smell protection technology ensures your contents are 100% smell proof.
