Turn tap water into delicious alkaline ionised mineral water

What if you could arm your body against bad guys just by drinking water? That’s the Alka Jug in essence – a jug full of alkaline ammo to help your body fight its battles and come back healthier than ever.

The Alka Jug turns boring, tasteless, and potentially harmful acidic tap water into delicious alkaline ionised mineral water – infused with health benefits and the peace of mind that comes with knowing what’s going into your body. It’s our simplest portable solution to bringing your water back to life, complementing your filtration system, without the need for new plumbing or hardware.

Inside the Alka Jug

Most tap water has an unhealthy pH of around 7 (some are even worse!). Using a unique filter that includes active carbon, biominerals and ceramic energy beads, the Alka Jug increases that pH by 2-2.5, making it alkaline. And this alkalinity is the key, with reported health benefits that range from easing acid reflux to reducing blood pressure and improving bone strength .

The cartridge also reduces heavy metals and harsh chemicals, and replaces the essential minerals and trace elements stripped out by water treatment, like magnesium, strontium, lithium, zinc and calcium. Plus (and this is important) negative ion minerals to help your body absorb minerals more effectively.

The even-better news? Even without the long list of benefits, Alka Jug water is deliciously refreshing and just nice to drink. Ahhhh.

The Alka Jug can produce 300 liters of ionized alkaline water, which is equivalent to saving 500 bottles of water. This can potentially result in significant cost savings as well as reduce plastic waste.

Replacing the Cartridge

There are two ways to check the cartridge life. The first way is to use a pH test drops. To do this, test a small sample of the tap water and then test the Alka Jug water for pH and compare the two. If there is only about 1pH difference between the two samples, then it is time to replace the cartridge. It is also recommended to obtain pH testing drops to see the difference of your source water's pH and the resulting alkaline water from the Alka Jug. This method provides a real assessment of the remaining life of the cartridge's capacity to alkalize.

Is the water from Alka Jug really healthier than regular tap water?

Absolutely, it boosts hydration, introduces beneficial minerals, and reduces acidity.

Does the Alka Jug remove essential minerals like regular water filters?

No, it enriches water with essential minerals and enhances absorption.

Isn't alkaline water just a trend without real health benefits?

Countless testimonials and studies affirm Alka Jug's health-boosting properties.

How do I know if Alka Jug's water quality is worth the cost?

Invest in your health with proven results and cost savings on bottled water.

Why does the new version of the Alka Jug does not have the electronic life indicator ?

We have done away with the LCD life indicator as this is not that accurate and at time it needed to be replaced, a solution that we did not find sustainable, therefor we have improved the system with a simple guide that is provided in the packaging with each Alka Jug. Here is our new Alka Jug manual, see attached. There you can see a schedule to read how many weeks your cartridge will last depending on the amount of people drinking from it and also whether it is also used for cooking. (please refer to the second page)
By using the manual’s instruction you wont need to rely on the display on the lid to know when it's due to replace the filter.
The manual is a very accurate alternative that works well without using the electronic lid.

Why does the water stays at the top and not getting filtered ?

The Alka Jug Cartridge is filled with many different minerals, larger than sand but smaller than gravel. The minerals can become compacted in case it has been sitting for a while with no mvement. Due to the presence of minerals in the media of the Alka Jug, it is important to note that shaking the cartridge can help release these minerals in case it becomes compacted. However, if shaking the cartridge does not resolve the issue, please refer to the troubleshooting steps provided below:
1) Shake the cartridge vigorously in an upside-down and sideways motion to dislodge any blockages.
2) Gently tap the cartridge upside down against a firm surface to help loosen any trapped particles.
3) Using a 50mm long opened-up office clip, insert it through the access hole in various directions to clear any obstructions.
4) Run cold tap water at a fast flow rate into the top of the cartridge, allowing the high water pressure to help force the water through. Try this for approximately one minute or more.
Please follow these troubleshooting steps and if the issue persists contact our customer service support.

Does the Alka Jug comes with an Alka Jug Cartridge ?

Yes, the Alka Jug comes with an Alka Jug Cartridge included. The cartridge is specifically designed to enhance the water by adding beneficial minerals and adjusting the pH level and ORP levels. It is an essential component of the Alka Jug system, ensuring the optimal filtration and ionization of the water.

Where can I find my complimentary Alka Jug Cartridge ?

With every purchase of an Alka Jug, you will receive a complimentary cartridge. To locate the cartridge, please open the packaging and remove the top of the jug. Inside, you will find the cartridge ready for installation. Enjoy the benefits of your Alka Jug with the included cartridge.

When should I replace my entire Jug ?

Our clients who have been using this jug for over 10 years have reported no noticeable impact on water quality. However, if you observe any signs of deterioration in the jug or if the taste of the water seems off, we highly recommend replacing the jug for your peace of mind. Ensuring the best water quality and customer satisfaction is our top priority. If you have any further concerns or questions, please don't hesitate to reach out to us.

How to secure the Alka Jug lid properly ?

The lid needs to be attached to the internal Reservoir before both the reservoir and lid go into the pitcher and before the cartridge is screwed to the bottom of the reservoir. Please refer to the guide in the link attached If you're experiencing difficulty with the lid not closing properly on your Alka Jug.

What is the material used for the body of the Alka Jug ?

The Jug utilizes food-grade plastic that is AS (Acrylonitrile Styrene) and BPA (Bisphenol A) free, ensuring its safety for long-term use by individuals.
The plastic has been tested and for more details on the report please refer to the link attached.

Is there any concern about the material of the Alka Jug affecting the water by leaching into it?

It is important to note that the materials used in the Alka Jug are designed to be non-leaching. They are specifically chosen to minimize the transfer of any potentially harmful substances into the water.
However, it's always a good practice to follow the instructions for proper use and maintenance of the jug. This includes regular cleaning and avoiding exposure to extreme temperatures, direct sun light or harsh chemicals, which could potentially affect the integrity of the materials.

Why do I have black bits in my water ?

The presence of black color in the water is attributed to carbon, and it is safe for consumption. However, it is understandable that some individuals may feel hesitant about drinking it, Rest assured that the black color will vanish within 2-3 jug flushings.

Why the water is cloudy ?

The cloudiness in the water is caused by an excess of bio minerals present. However, with additional flushing, the cloudiness will dissipate. It is important to note that the water is safe for human consumption.

What is the recommended maintenance for the Alka Jug ?

The recommended maintenance for the Jug includes regular cleaning and filter replacement. It is advised to clean the jug and its components. Wash your Alka Jug regularly with mild soapy water. Note; Don’t soak cartridge or lid in soapy water!

Can I consume water from the jug immediately, or is there a recommended waiting period?

Water from the Alka Jug is best consumed fresh otherwise when sitting open to the air it oxidizes over time. This can lead to an off-taste. Best to keep ionized alkaline water in a container with a lid on.

Is the life indicator for the alka jug is the best way to know when to replace my filter ? What should I do if it stopped working ?

In our previous model of the Alka Jug, an electronic life indicator was included, featuring an LCD timer. This timer would start at 300 liters and count down 2 liters per day, per person. When the timer reached 0, it would indicate the need to change the cartridge. However, for the most accurate determination of when to replace the cartridge, we recommend using pH testing drops to monitor the water's pH level. As the pH approaches neutral, it is an indication that it is time to replace the cartridge. You can purchase the pH testing drops from our website.
In our new Alka Jug model, we have made improvements to provide a more sustainable and user-friendly approach for determining cartridge replacement. The exact method will depend on usage patterns, and you can find detailed information in the attached guide.
