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.
It took a week for the zeolite filter order to arrive. That's why I give such a low rating, the products themselves are 5 stars.

Response from Alkanatur
We are very sorry for the delay in delivering your order and understand that it has affected your rating. We are already analyzing what happened with the delivery company to improve delivery times and prevent it from happening again.
We are glad to know that, despite the delay, you are satisfied with our zeolite filters and that the products deserve those 5 stars.

I preferred a glass jug but I haven't ordered it because it has a small filtering volume. They should design a glass jug with a filtering capacity of 1.5 l. The order also took a long time to arrive.

The Alkanatur service is fine, with no problems. But the postal service is lamentable as always. I have received your packages through other agencies and in 2/3 days I had the products at home. It is not normal for a package to take 10 days and thanks to the fact that they have well protected the filters, otherwise they would have arrived to be thrown in the trash. The carrier is lamentable.

Hello, black charcoal keeps coming out and I have filled the tank 8 times and emptied it but it keeps coming out, less each time but that didn't happen the first time
Translated reviews
Response from Alkanatur
It is completely normal and natural for charcoal particles to remain in the water. Our filters are made solely of natural products: 100% natural coconut vegetable charcoal and magnesium. We import the coconut charcoal directly from Mexico, and we do not alter the nature of the material.
Due to its state or even due to the transportation of the material, the charcoal may be more broken and crumbled and release more charcoal particles, and even stain the water black. Other times, if its state is more compact, it releases less but it is normal for it to always release black particles due to what we mentioned, because it is an ecological product without any type of chemical treatment.

After 5 days without news from the GLS carrier or Alkanatur, I wrote to Alkanatur and it turned out that the order had not been delivered to the transport agency. No one from the company contacted me for the delivery. They went in the morning and I was not there. I still do not have the order after 10 days. I have requested by phone that it be taken to a parcel shop and we will see if I can finally pick it up after 10 days. It is not just the delay that bothers me but the lack of assumption of responsibility. This is not the experience I had with previous orders so I hope it was an exceptional incident.

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.

“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,

I was looking forward to the pitcher, but it has not satisfied me. I can't put it in the fridge, being so round it doesn't fit in the door and being tall it doesn't stand up on the shelves of the fridge. Also, when pouring water, I don't know if it doesn't fit well but it doesn't come out in a stream, it spills outside, it doesn't aim well in the glass, you know. What a pity, let's see if in winter when cold water is not needed I can use it.
