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.

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.

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...

The pitcher does not fit in the fridge door. It is quite inconvenient.

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…

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.

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.

I have been trying the water for a few weeks and after filtering it has a taste that I do not find pleasant. Also, I have a device that measures solid residues after filtering and the result has not been significant compared to the data I get from measuring the water that comes directly from the tap. I expected something different, to be honest. The worst part is the taste.

The filter is leaving a sediment of sand in the jug and in the glass. Checked that it is not from the water, but from the filter. The tap water also tastes better than from the jug. I have written to Alkanatur without any response. I had to throw away liters and liters of water to see if it improved but nothing. Frankly disappointed, despite it being a recommendation from a relative.
