I bought 3 filters for the metal filtering bottle 2 months ago and they told me it would soon be back in stock so I could buy it. I'm still waiting. I bought 3 filters for the metal filtering bottle that was out of stock and they told me it would soon be back in stock. I'm still waiting.

I activated the filter as indicated in the instructions. But it must not be functioning because I did the liquid test and it comes out purple/blue.

Response from Alkanatur
Hello,
As you can see in the instructions, this is the color of the pH that should come out, which means alkaline water. If you have any questions, you can contact customer service.

Greenish appeared on the edges. I sent an incident and they tell me to wash it
Translated reviews
Response from Alkanatur
Hello, Yolanda:
We regret that this situation has caused you a bad experience.
The appearance of greenish color is usually not due to a defect in the jug, but to a natural phenomenon that can occur when chlorine-free water remains stagnant for several days, especially in hot weather or if the jug is near a source of light or heat. It is a similar effect to what can be observed in ponds or containers with stored water for a while.
To eliminate it, we recommend performing a deep cleaning with a small amount of diluted bleach in water, letting it act for a few hours and then rinsing the jug thoroughly.
Additionally, to prevent its appearance, we advise performing a weekly cleaning of the jug. If you also observe whitish residues on the walls, you can use a mixture of warm water and vinegar in equal parts, letting it act for a few hours before rinsing. This helps to eliminate mineral deposits and restore the shine of the product.
We regret that our instructions did not meet your expectations, but this is the usual recommended procedure for this type of situation.
Best regards,
Alkanatur Team

The material of the lid is too fragile and unstable. When filling the jar, the lid through which the water is introduced lifts very easily and releases all the water even when almost all of it has already leaked out. Additionally, after just one month of use, the spout through which the water is released broke.

Some shameless people.

And they tell you to comb your hair. This has happened to me several times. Oh, and at Bio Cultura Madrid I went to talk to them and they were unpleasant!!!

When putting the lid on the jug, the water filling spout is slightly raised. This is due to the pressure that the vessel exerts on the entire upper lid assembly. One more thing: if I overfill the jug, when pouring water into a glass, the unfiltered water that remains before the filter comes out through the filling spout.

“Alkalinizing” the water, a term invented by this brand, is useless. Scientifically speaking, it is like Brita or so many other jugs. It improves the taste of water a lot, but it does not improve your health.
Translated reviews
Response from Alkanatur
Hello, Alfonso:
Thank you for sharing your opinion.
We want to clarify that Alkanatur is not just a jug that improves the taste of water. Our filters reduce substances such as chlorine, certain heavy metals, and other compounds present in tap water, in addition to providing minerals like magnesium.
Regarding alkalinity, this occurs naturally during the filtration and remineralization process of the water. On our website, we have studies, analyses, and certifications that explain in detail how our filters work and the characteristics of the obtained water.
We understand that there are different opinions on this topic and we respect all of them. In any case, we regret that the product did not meet your expectations.
Best regards,
Alkanatur Team
