Well, the product is very good. But the shipping is terrible. When you pay, you receive confirmation of the payment, but no estimated arrival date, no shipping reference, no transport company... nothing. Also, it takes about 10 days for a national shipment! I feel bad that companies like Amazon are taking market share from them, but there are reasons!

The bottle is fine, the shipment was correct. But I thought the bottle alkalized the water like the pitcher, and it simply filters it instead.

I have rated the filter very poorly because the only thing it does is reduce water pressure. They ask me to evaluate the product and I do, and the response I get is that this is not the place to say that, to talk to customer service. Okay. And if I talk to customer service, will they refund my money? Because if so, I will withdraw the criticism, while not because it is you who asked for my opinion, I did not put it for free. And by the way, they have not made it public. That says a lot. Who only publishes good reviews........

I have been using the pitcher and filters from another brand (Brita) for years, since specifically 2011 when I moved from Madrid to Paris and then living in other cities like Valencia and now Barcelona and honestly I have always been satisfied with their taste, quality-price, easy purchase... A month ago we decided to change taking advantage of the fact that the pitcher was already in bad condition and try this brand that supposedly offers better filtration quality and despite its price (more than double for both the pitcher and the filters), and after just 3 weeks of use I can say that I will not buy either the pitcher or filters again. The first filter did not last even a week (with an average of 4 liters per day of use and some days less). Supposedly it should last me 3 months and it hasn't even reached 3 weeks of use of the first filter, the kettle is full of limescale and the water tastes unfiltered. The same thing happened with the previous brand but after more than 40 days of use. I do not recommend it and I am very very disappointed and angry because I was certainly happy with the previous brand. But for being Spanish and certainly more natural, after its use I do not think about it at all. A SCAM.

Response from Alkanatur
Hello, thank you for sharing your experience.

We would like to clarify an important point: the Alkanatur pitcher does not remove limescale from the water, as limescale (calcium and magnesium) are natural minerals beneficial to the body. Our filtration system is designed to reduce chlorine, heavy metals, and other contaminants, while precisely maintaining those healthy minerals.

For this reason, it is normal for limescale to appear in the kettle, especially in areas with hard water like Barcelona, and this does not mean that the filter is not working properly.

Regarding the filter's duration, with an average use of 3-4 liters daily, it should last approximately between 2 and 3 months. If in your case you have noticed something different, we would like to understand better what may have happened.

If you want, you can write to us privately or to our customer service to review your case and help you. We would be happy to do so.

Despite following the filter activation protocol and after many filtrations, the water when bottled in a glass bottle changes taste within minutes and is very unpleasant. Customer service leaves much to be desired, the response to my feeling when I wrote, besides taking longer to respond than they say, was there is no solution and that's it, I would have expected something more honestly when it has been at most 2 weeks since I bought it.

Response from Alkanatur
Hello, thank you for sharing your opinion.

Regarding what you mentioned about customer service, we have reviewed your case and see that your inquiry was sent on Tuesday, February 17 at 21:44 and received a response on Wednesday, February 18 at 11:17, that is, the next morning within our customer service hours.

We regret that the solution offered did not meet your expectations. In some cases, the change in taste may be due to different factors, such as the initial adaptation of the filter or the specific characteristics of the water in each area.

If you wish, we would be happy to review your case again and help you check that everything is working correctly. You can write to us again and we will look into it with you in detail.

I use the pitcher, and I am very satisfied, not so much with their shipping method by the company GSL, with a cost of €10, (much higher than with many shipping companies), without receiving information about my shipment, having to contact the company directly twice to know about my package, which they left at a pickup point without any direct notice to me from GSL or the company I had spoken to days before stating that I had no information since my purchase. GSL is one of the worst shipping companies and the most expensive, I hope they start using another. For this, I give 3 stars, good product but the shipping issue is a hassle, high cost and poor service. This is not my first purchase with Alkanatur.

Dear Candela,

We sincerely appreciate your opinion and regret that you had an unsatisfactory experience with the shipping service. We are glad to know that you are satisfied with the pitcher, but we understand that the issues with GSL and the shipping cost have affected your overall experience.

Thank you for your understanding and support.

The instruction manual is not clear. When the filter has been activated, it does not explain the next steps to use it. How far should it be filled with water? And should the pitcher be filled or is it from where the filter is? Because then it filters very little water, half a liter. Not one and a half liters as published.

Actually, I am happy with the pitcher, but I have only been using it for a month and a half and for the last two weeks the taste has changed a lot, now it is very bitter and not pleasant to drink. The filter is supposed to be changed every 3 months, but after a month it has stopped working well, it seems.

The order was quite delayed and when it arrived, all three filters were broken, just opening the package all the microbeads from the filters spilled out. When I tried to contact them, they did not answer the phone (not even during their working hours), I had to resolve it through their email. Bad experience.

The intention is to promote health and the pitcher is made of plastic. Also difficult to refill and clean. It's not worth its price. The filter does indeed remove flavors from the water. That's why I rate it higher.

Hello yes, but our pitcher is made of 100% toxic-free plastic. It is certified by Dr. Nicolás Olea, an expert in endocrine disruptors, so it is a completely safe container. We have the certificate posted on the website if you want to check it. Most plastics we acquire from bottled water contain toxins that migrate into the water.

Hello, When opening the package, the lid that opens for the water to fall fell off and broke on one side. It has been like this from the very beginning. I can place it, but it is broken. I consider it too delicate, as it simply fell on the countertop and a small side tab broke. In summary, the product is new, but with that defect from the start.

I like the taste of the water once it goes through the filter since in my area it is very hard water and I think that with the pitcher I have managed to improve the taste, however the pitcher seems to me to be of poor quality, the lid stays half open and does not look like it has great durability. I expected better components. I would prefer it to be made of glass or similar.
