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.
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.
Best regards.

I wanted to comment on two things I am quite dissatisfied with regarding my purchase, the first and main one is that I invested more money in buying the glass jug and to my surprise the inner piece where the filter is placed is plastic... And the second thing that surprised me is the time it took for the shipment.

Response from Alkanatur
We are very sorry that your experience with the purchase was not as expected. We understand your comment regarding both the inner piece of the jug and the delivery time of the order.

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.

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.

Although I love the glass option, I did not expect less capacity. The lid through which the tap water enters does not close properly and the water flows in a very wide stream, so a lot spills when refilling the Alkanatur bottle for the fridge or gym or school bottle. Well, it is not more practical than the previous one for me.

I think it is a very high-quality product but if you have a sensitive stomach, it may not sit well. The truth is that it is nobody's fault, but I bought it and had to stop drinking the water because of how all those minerals sit in my stomach. Now I am considering whether to buy another different filter, the green one, which I also don't know how it will sit with me. In short, I was super excited about my pitcher and I think it should be warned that tolerance can be complicated for some stomachs.

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.

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.

The Alkanatur team.
