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.

Just to comment that GSL does not deliver to the doors of apartments in buildings without elevators, they ask you to go down and pick it up at the building's door, which is a problem for people with reduced mobility. The bad note goes to the transport company, the product is excellent.

There is an improvement in the water, however, at the beginning of the filter change it does not taste very good and you have to wait a week for the bad taste to go away.

“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

The filters release a lot of particles and the bottom of the jug turns black. They say it's normal and nothing happens, but seeing the water in that state makes it anything but appealing for consumption. The day they solve this issue, I will be a customer again.

Very expensive. The design of the pitcher is bad because if it is filled you can't pour water until it has filtered all because otherwise it spills over the top. This doesn't happen with other brands.

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.

The jug is very pretty and I love that it is made of glass. However, my main issue is that the glass seems to be quite delicate, and this aspect is not sufficiently explained in the product description. While washing it before its first use, it suffered a small bump and the handle cracked. The truth is that I am still quite upset, especially because I fear it won't take long to break completely. I feel especially bad because it was a gift for my 80-year-old mother, and now I think that the plastic version would have been a more suitable option for her. I think it would be advisable to clearly warn that it is fragile glass and should be handled with special care. I have other glass jugs (not filter jugs) that I have had for years and they have never cracked as easily as this one.

I am a little disappointed, I don't know if I had too many expectations or if the jug is not working properly. A white layer forms in the middle of the jug that looks like dirt, the jug never fills completely, it always stays a little more than half full and in the filter area, there is stagnant water.

It is a bottle too big to carry, they should release a smaller version, plus it is through suction with a plastic straw (it does not have BPA, okay, but it is plastic...). Also, it should be noted that a lot of effort is needed in the suction, which is not recommended for people who suffer from bruxism, as it puts a lot of strain on the mouth muscles. Other than that, the filter quality, as always, is magnificent.

Hello! very good idea about the glass.. but the amount of water it holds is absurdly small... I imagine there must be some reason but it takes up a lot of space yet hardly holds any water... it's a hassle to keep refilling...

Dear Albert, we sincerely thank you for your opinion. We understand your frustration with the capacity of the glass and appreciate your feedback. The reason for the size is that analyzing our customer base, a significant portion consists of elderly people or those with children.

I ordered the new glass pitcher and it arrived with a dead fly inside the pitcher. I wrote to their customer service and they replied that it could be solved with water and soap, and that’s what I’m doing. I still haven't used it because I am disinfecting it, as I am immunocompromised. And since I don’t know if it can be put in the dishwasher at high temperatures, when I start using it I will give my opinion about the pitcher. But so far the experience has not been good at all.
