Customers praise Alkanatur for clear improvements in water quality and taste, noting that filters make water feel purer on the skin, remove flavors like chlorine, and improve daily drinking water. They highlight practical, user-friendly features: easy installation, fast and efficient shipping, attractive glass jugs, and reliable filtration that reduces plastic bottle usage and waste. The support experience is consistently commended, with several mentions of helpful, responsive service and after-sales assistance. Overall, buyers express satisfaction with product performance, design aesthetics, and the positive impact on daily hydration.
For now, I don't like it much. I had bought it mainly because of the lime, and it turns out it leaves everything whiter than before, the shower screen, faucets, etc.
Translated reviews
Response from Alkanatur
Hello Antonella,
We regret that the product did not meet your expectations and that you had problems with limescale residues. Our filters, being ecological, do not eliminate limescale, as they are natural minerals from water. They can help reduce it but not eliminate it. For this, in hard water areas, customers usually have a water softener to avoid this on shower screens and faucets.
Sincerely,
The Alkanatur team.

I have placed an order for a jar. 2 weeks later it still hasn't been delivered. On 22-06-2026, GLS sent an email saying they would make the delivery. I was home all day and on 23-06-2026 I received another email saying that I have to go pick up the jar at a delivery point for being absent from my home. They did not knock on my door. They also did not call me on the phone......GLS lies and does not do their job.

I have ordered two jars and I have only received 1. I sent a message on Monday to report the problem. The answer was an apology for any inconvenience and that the pitcher would be sent as soon as possible. Today we are Friday and I haven’t yet received a message of any shipment. It doesn’t have to take a week to send the missing jar! It was the first time that I placed an order after a recommendation from a friend but honestly I am very disappointed.

My opinion about Alkanatur is positive, but they should change shipping companies because GLS, instead of delivering the order to my home, left it at a pickup point because it was more convenient for them. Without consulting and without prior notice (we were at home, so they cannot excuse themselves by saying that no one was at home). Because of that negligence from GLS, it took me several days to have the order since the pickup point where they left it was not convenient for me.

I ordered a replacement filter for my jug, I received a complete jug, with its corresponding replacement. I informed them of the error. And besides not thanking me (which for me would have been easier to stay quiet and keep the jug worth seventy-something euros), they told me I had to wait for them to come pick up the jug and deliver the filter. I mentioned that I urgently needed the filter, since the error was theirs and the filter inside the jug is the same as the one I had ordered, if I could keep that filter and return the jug, as I obviously did. But gentlemen from Alkanatur, first you thank the customer for reporting the error, and then, the customer should have as few inconveniences as possible. In summary, negligent in order preparation, unkind and unhelpful.

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.

“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,
