The first filter lasted 39 days with a consumption of 9 liters/week. Very far from the 400l. that, according to the sales information, they claim it usually lasts.

The filter cannot be placed on the bathtub faucet. It should have a system that allows it to fit when the wall is very close to the spout.

The water comes out with a lot of hardness after filtering.
Translated reviews
Response from Alkanatur
Hello, thank you for your review. We are very sorry that you are not satisfied with the product. Our filter does not remove minerals from the water, so hardness is not reduced. In fact, it raises that ppm because it adds 18mg of magnesium per liter. Our water is alkaline water, that is, water rich in minerals. We will contact you from our Quality Department to study your case in more detail and see how we can improve your experience.

I am not happy at all. I placed an order, it was duplicated. I was charged twice and I have been waiting for more than a week for a response through PayPal.

Hello María José. Thank you very much for your review. We have reviewed your case and noticed that two orders have been placed, which has led to the charge of both. However, we will contact you today to find the best solution.

I'm not convinced, the water still tastes like chlorine.
Translated reviews
Response from Alkanatur
Thank you for your feedback. Coconut charcoal absorbs chlorine perfectly and it cannot be that a filter is damaged and has that taste. It is possible that the taste you notice is from the minerals themselves or from magnesium. We regret that you do not like the taste of the water and the product does not suit you. Taste is a more personal matter, that is true. In any case, remember that you have a 30-day satisfaction guarantee. We will contact you to either find another solution, perhaps the low magnesium emission filter suits you better, or if not, process the return of the product.

The plastic bottles of 7 euros each are category 1, like one I buy at the supermarket that is supposedly not to be refilled.
Translated reviews
Response from Alkanatur
Hello! We regret your rating. The numbering of plastics is a complex issue. Number 1 is a classification. The problem is not the material, but the additives that are added to this plastic, which depends on each bottle, each brand... This category is almost always used to indicate plastic bottles, so ours falls into this category, but not all brands work with BPA-free or other toxic materials. Our Alkanatur bottle is BPA-free and is free of these toxins. You have the certificate of absence of BPA, esbo, and phthalates: https://alkanatur.com/certificados/ (it's the 3rd).

Hello, I really liked the jug, very practical, but I think the filter is defective since I have filtered the water more than 5 times and it still presents certain black particles.
Translated reviews
Response from Alkanatur
Hello, we are very sorry for your rating :( Anyway, we want you not to worry about this. It is totally normal and natural for there to be carbon particles in the water. Our filters are made solely of natural products: 100% natural coconut 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 carbon particles, and even dye 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.

It demineralizes the water.
Translated reviews
Response from Alkanatur
Thank you for your feedback and for your purchase. Our jug does not demineralize the water. It removes toxins, but not the natural minerals from the water. Additionally, it adds magnesium, so it still mineralizes more. With the pH reagent included in the pack, you can test the pH between the filtered water and tap water, or for example, bottled water and see the differences. If you have any questions about the product or how to perform the test, contact us via WhatsApp, email, or phone and we will gladly assist you. Best regards.

We did not like the taste of the water. It's a shame because we had high expectations due to the amount of studies it had and the good comments, but none of the family liked the taste. I understand that taste is a very subjective matter, but it is sad to buy a product and not end up using it because it does not meet your expectations.

The jug does not seem to have any effect. The water is cloudy after several filtrations, it does not change the taste at all, and the bottom of the jug is full of lime.
Translated reviews
Response from Alkanatur
Thank you for your feedback and for your purchase. We are very sorry that you are not satisfied with the product. The jug does not remove the natural minerals from the water, being alkaline water it is therefore rich in minerals. To avoid those whitish stains it simply requires a little extra care, as indicated on page 9 of the instruction manual. In any case, we will contact you to provide a solution. Best regards.

The water tastes a lot like chlorine, more than before filtering it. We use solarized water (which no longer has that taste) and it tastes bad after filtering it...

Terrible consumer experience. I requested a quote for the filters and they contacted me to say that the local salesperson would call me. A few days later, the salesperson called me, who only asked me about the water system I was using, I told him and he dedicated himself to criticizing the competition. In the two or three minutes we talked, he finally told me he would send me the information by email. I decided not to opt for those filters due to the price and lack of clarity and bought another one that arrived with an instruction manual that has nothing to do with the filters I bought. I requested the instructions and the response was to call a plumber and that the instruction manual is that, which is a generic one (that they must have found on the internet because it has nothing to do with their filters). Regarding the quality of the water, I cannot comment since I have not tried it yet, but I am clear that there are other companies that make good products and I doubt they can do worse in customer service.

Response from Alkanatur
Thank you for your feedback. We are very sorry that your experience was negative. Our Commercial Department tries to advise you based on the area you are in and if you are looking at other brands, to comment on differences or similarities between ours and the competition so that the customer can make the decision they consider best. Regarding your experience with the installation of the equipment, we regret that the plumber did not want to install it. As we mentioned, the faucet instructions are generic, they are not specifically for use with the equipment you purchased, but rather it is a faucet suitable for any filtration equipment, osmosis, or even just to use as a faucet. To try to clarify this, the colleagues from the Quality Department recorded and sent a video personally explaining how to install the faucet. Once again, we are sorry if your initial experience was not satisfactory, but at Alkanatur we always do our best to help and keep the customer happy. Best regards.

The plastic of the jug and especially the part where the filter is placed looks of low quality, not very resistant. It is true that the taste of the water improves but it does so with other much cheaper jugs and the black carbon particles that settle at the bottom do not inspire much confidence…
Translated reviews
Response from Alkanatur
Hello Mireia, thank you for your feedback. The plastic of our jug is of high quality and completely free of toxins, certified by Dr. Nicolás Olea - IBS of Granada. Being a material that does not contain chemical hardeners or other types of toxins that are normally used to thicken materials, it seems less resistant because it is thinner. It is the price to pay for a completely safe material free of endocrine disruptors. About the black particles. It is normal and completely natural for the filter to release some little bits of carbon. Alkanatur filters are made solely of natural products: 100% natural coconut vegetable carbon and magnesium. We import coconut carbon 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 carbon may be more broken and crumbled and release more carbon bits, and even stain the water black. Other times, if its state is more compact, it hardly releases dust and the water comes out completely transparent. The bits may seem "annoying" to the eye, but they pose no danger. In fact, the softer the carbon is, the more toxins it is capable of absorbing.

After performing electrolysis on the purified water from the jug, I find too much residue. I have informed Alkanatur, and I am waiting for a response.
Translated reviews
Response from Alkanatur
Thank you for your feedback. We will try to respond to your question as soon as possible. In any case, it should be noted that water with minerals will always have that effect with electrolysis tests, it is not because it has impurities, it is because these machines react to any substance in the water. That is why distilled water (without minerals) does not react. It is important to note that minerals are necessary in our diet, as they are used for many functions in the body: from maintaining bones, heart, and brain to our hormones. Therefore, it is essential that these are also present in water. Minerals in water help regulate a correct pH level and, in turn, have greater bioavailability. Distilled waters are acidic, dead waters, and their consumption can have serious health consequences. We will provide you with a more complete response in the email you sent. Regards.

Maybe your product is good but the water in my town is terrible, with a lot of lime. Despite the filtering, there is still lime at the bottom. I followed the instructions. Anyway, I use that water for cooking. Thank you very much.
Translated reviews
Response from Alkanatur
Thank you for your feedback. Our product does not eliminate limescale, which is the union of minerals such as calcium, magnesium, potassium, sodium, etc., as we explain in detail on the website. Our filters are 100% ecological and certified. They are composed solely of coconut shell charcoal and magnesium. Our filters remove up to 99% of toxic substances from the water, but do not remove natural substances, such as minerals. Those white "residues" that you see at the bottom are mostly calcium. Conventional filters add chemical compounds inside, usually ion exchange resins, which come from petroleum (benzene and styrene) and remove these minerals, leaving the water practically dead and with a very acidic pH level. We regret that the product is not completely to your liking, but you can consume that water with total safety as the toxins have been removed.
