This is a concentrated product only to be used to refill a 500 mL LISTERINE COOL MINT® ZERO Alcohol bottle with a water fill line printed on the front top label and must be diluted with water before use.

Step 1: Start by thoroughly rinsing the empty 500 mL LISTERINE COOL MINT® ZERO Alcohol bottle with drinkable water. Do not use soap or wash in the dishwasher.

Step 2: Add room-temperature, drinkable water to the water fill line shown on the front top label of the empty bottle.

Step 3: Pour one entire mouthwash concentrate into the bottle with the water. Replace cap and shake gently.

Step 4: After dilution, follow the directions for use on the 500 mL LISTERINE COOL MINT® ZERO Alcohol bottle: Rinse for 30 seconds with 20 mL (2/3 fluid ounce or 4 teaspoonfuls) morning and night. Do not swallow.

Diluted product can be used for up to 3 months after dilution.

Children under the age of 12 should not dilute or mix the concentrate refill. Dilution by children 12 years of age or older should be under the supervision of an adult. Do not use diluted product in children under 6 years of age.

Keep out of reach of children. If more than used for rinsing is accidentally swallowed, get medical help or contact a poison control center right away.

Both the Starter Kit and the Refill Pack allow you to mix three full 500 mL bottles of COOL MINT® ZERO. The Starter Kit comes with a full bottle of regular COOL MINT® ZERO and then you will mix the other two. The Refill Pack comes with three 100 mL concentrates that you will use to create three separate 500 mL COOL MINT® ZEROS, but to do that you will need an empty 500 mL bottle of COOL MINT® ZERO that contains a water fill line at the top. If you do not have one of those bottles, we recommend you purchase the Starter Kit to begin your more sustainable Listerine journey!

One FULL concentrate should be used with each empty 500 mL mouthwash. After rinsing your reusable 500 mL bottle, you want to fill it up with water to the water fill line and then add an entire bottle of the 100 mL concentrate.

No, you should use a FULL bottle of 100 mL concentrate per 400 mL of water to guarantee that your newly mixed bottle of COOL MINT® ZERO is just as effective as our regular COOL MINT® ZERO. It is important to carefully read and follow the directions on the label to obtain the proper concentration. Directions for how to dilute or mix the concentrate to refill your empty bottle of COOL MINT® ZERO can be found on the back of the smaller concentrate refill bottle (100 mL). You must use one FULL bottle of 100 mL of concentrate and 400 mL of water.

When mixing the water and the concentrate, we recommend using room temperature water, so not too hot and not too cold, you want it to be juuussst right.

Yes, we always recommend adding the water first and then pouring in the concentrate. This allows you to make sure you are using the right amount of water to dilute the product with (400 mL as indicated by the water fill line) and avoids excess foaming.

It doesn’t take long at all! You want to gently shake the mixture of water and concentrate until they are fully blended together. Once the mixture is fully combined, you do not need to shake it again.

Once fully mixed, the diluted product doesn’t need to be shaken again and can be used for up to 3 months. As long as you are using flat, drinkable water, the efficacy and the shelf life should not be impacted by variations in the water used.

If following the directions properly, you can reuse the 500 mL bottle with LISTERINE® concentrate refills for up to two years from purchase.

No. To wash your 500 mL reusable bottle, simply rinse it thoroughly only using drinkable water. Do not use soap or wash in the dishwasher.

No, we only recommend using the 100 mL concentrates with a 500 mL bottle of COOL MINT® ZERO that contains a water fill line at the top. FOR REFILL PACK: If you do not have one of those bottles, we recommend you purchase the Starter Kit to begin your more sustainable Listerine journey!

Rated 5 out of 5 by from Must have!! I love Listerine! I have used many many different mouthwash products but have always come back to this one. It blows the competition out of the water. I can feel this product killing any unwanted bacteria, bad breath, or germs instantly. Leaves my breath extra fresh for hours on end.

Rated 4 out of 5 by from Listerine Cool Mint Review I really like this Listerine flavor. It's very refreshing and cooling vs the others.

Rated 5 out of 5 by from Refreshing sensation The product fulfills what it promises, at least if you have a feeling of cleanliness and freshness after use. Even having a value a little above the competitors, I always end up opting for Listerine for the refreshing power it leaves in the mouth after brushing.

Rated 3 out of 5 by from Not the Same Mouthwash I have used this Zero Alcohol Listerine cool mint before and it definitely doesn't give the same refreshing feeling as the Listerine with alcohol. My mouth just doesn't feel as clean after using it. The taste isn't as bad. But when I use mouthwash, I want to feel the burn and feel like it is getting my mouth clean and fresh. Especially after brushing my teeth after a shower in the morning before work.

Rated 5 out of 5 by from No alcohol mouthwash I was rather surprised how clean my mouth felt after using this mouth wash. I have always used ones with alcohol because I thought it cleaned better but it made my mouth burn. This mouth wash didn't hurt my mouth and worked just as great, if not better. Would definitely recommend.

Rated 5 out of 5 by from Greatest mouthwash ever!!! This is the BEST mouth wash I have ever used. I love the concept of reusing the same bottle. It reduces waste which is better for the environment I will be buying this brand of mouthwash from now on and recommending it to all of my family and friends!!!!

Rated 5 out of 5 by from Less Plastic, Less Harsh! I really appreciate that this concentrate allows me to mix up a batch of my favorite mouth wash without having to purchase another plastic bottle!! This diluted concentrate is less harsh than the bolder blue antiseptic mouthwash but foams up quite nicely and leaves my mouth fresh.
Date published: 2022-09-05
Rated 5 out of 5 by from Favorite mouth wash I have always loved the benefits of mouth wash, but my mouth can’t handle any spice or burn, and I could not believe that this new Listerine cool mint did not burn one bit, while also giving that same cooling effect and scent of a freshly rinsed mouth. I actually find myself wanting to rinse more than I have to because I love the taste and how it feels. And I absolutely love the idea of a concentrated refill, so innovative to save plastic!

Rated 5 out of 5 by from Live it! I’ve already been an avid Listerine user and this product makes it so easy to refill my bottles. I love the fact that it came with a large bottle and the small bottles for refills. It makes it easy to stock up on a product I use a lot versus having to go to the store every time I’m about to run out. Highly recommend if you’re an avid user of listertine!

Rated 5 out of 5 by from Amazing! I am pretty picky when it comes to mouth washes so I am skeptical obviously but I can say since trying this one, I am completely switching to it! It is SO refreshing and makes your mouth feel so clean without the burning!

Rated 5 out of 5 by from This was refreshing I've used Ultraclean Listerine the last 10 years, but this Zero Alcohol is so refreshing! It doesn't have the burn, but still makes my mouth taste fresh all day long! I was surprised it worked this well!

Rated 5 out of 5 by from Listerine cool mint I received the Listerine cool mint concentrate kit from Home Tester Club for my honest review. Honestly I love it because I normally use Listerine brand anyway but also because now it comes in a concentrate so you’re wasting away less Plastic then you would normally with the big jug. I definitely recommend everyone switching to this one because that will save a lot of waste from goin to the land fill

Rated 4 out of 5 by from Bad breath be gone After some recent dental work I was making mouthwash a habit.i always try to be ecological and so the ability to refill and reduce plastic by 60% is a selling point, and the bad breath from morning coffee is erased.
