Alkanatur 2.5 Liters Water Filter Pitcher Review

Water filter pitchers provide a simple and more cost-effective way of getting clean drinking water at home. They are completely portable, easy to use, and unlike the other filtration systems, they basically require little to no installation – there’s no altering of the plumbing system.

These pitchers come in a wide variety with different features and qualities that differ from one brand. Today, we’re going to look at the Alkanatur water filter pitcher, which is one of the top options in the market. It’s more than just a water filter as it’s not only able to eliminate impurities from the water, but it also alkalizes and ionizes the water. You get clean, healthy water with balanced pH levels and better taste.

It does all these using a 100% natural process. No chemicals or salts are added to the water. The pitcher and the filter are manufactured in Spain, with all the materials sourced from within Europe. The build quality is good, and the capacity of the pitcher is pretty decent.

Generally, this Alkanatur 2.5 Liters Water Filter Pitcher filter pitcher has much to offer, and we’re going to share more about it, including its performance, benefits, and some of the downsides highlighted by users.

Filtration Performance

The Alkanatur uses a unique filtration process that features an activated coconut carbon filter and an active bioceramic filter. It’s a unique and efficient filtration system that’s approved/certified by the European Committee (CE), Restriction of Hazardous Substances (ROHS), and Society Generale Surveillance (SGS)

It’s also certified by the Ceramic Institute of Galicia (Santiago de Compostela University, Spain). It works effectively to filter out different kinds of contaminants and also to alkalize and ionize the water.

The activated coconut carbon filter has tiny pores that are 2nm thick, which is 3 to 8 times smaller compared to other leading brands (the industry average is around 4 to 5nm). Moreover, the amount of activated coconut charcoal used is twice that of other water filter pitchers. All these enhancements allow for better and more effective filtering.

The media is capable of removing up to 99.9% of all chlorine content in the water and heavy metals like lead, mercury, and arsenic. It also filters out fluoride, pesticides, VOCs, nitrates, excess calcium, trihalomethanes, and much more. The tiny pores as well allow it to capture and filter out up to 99% of all particles lurking in the water, including microplastics.

On the other hand, the active bioceramic filter helps alkalize the water by adding 18mg of magnesium into the water while retaining potassium. Magnesium and potassium are essential minerals that help prevent and improve our health.

The addition of magnesium helps generate alkaline pH of between 8.5 and 9.5 based on how acidic your tap water is and the amount of impurities it contains. Most users reported that the pH of their water after filtering with the Alkanatur pitcher was around 8.5, which is a much healthier alkaline state.

The best part is that no sodium is added to the process. Most conventional alkaline water filter pitchers often use ion exchange resin, which usually adds sodium to the water in the process of softening and alkalizing it. The Alkanatur 2.5 Liters Water Filter Pitcher uses a bioceramic filter, not an ion exchange resin. It doesn’t add any sodium to the water, which is beneficial considering that sodium is linked to several health problems.

In fact, it does the opposite. It removes sodium that’s already present in the source water. It does this by displacement – as magnesium is added to the water, sodium gets removed in the process. Therefore, you get sodium-free water which is essential if sodium is a great concern for you.

The bioceramic filter also ionizes the water, making it produce powerful antioxidants that boost the body’s immune system. It generates an antioxidant capacity of up to -700 ORP, which is way better than most ionizers and allows the water to effectively neutralize the harmful effects of free radicals within the body. The outcome of this is better cell hydration and regeneration, and basically overall improved cellular health and immune system.

Users were really pleased with the quality of the water produced by this Alkanatur pitcher. Most people mentioned that they could easily tell the difference between the tap water and the filtered water from the pitcher. The filtered water is crystal clear and clean, with a natural fresh taste that’s smooth and more appealing than the taste from the tap water or filtered water from other regular water filter pitchers.

Besides that, the filtered water from the Alkanatur 2.5 Liters Water Filter Pitcher retains most of its beneficial properties a little longer (up to a week). The only thing that will be affected quicker is the pH level of the water, which tends to change from Alkaline to Neutral 48 hours after it‘s produced.

The other impressive thing is that the filtration process is 100% natural. There’s no sodium added, and it uses no electricity, batteries, or titanium electrodes. The bioceramic filter media is also antibacterial, hence no mold or bacterial growth is likely to occur within the filter system.

However, you can only use the Akanatur to filter municipal water. It’s not meant for well water or untreated water that’s biologically unsafe – it’s not able to eliminate bacteria, viruses, or parasites. It may not also remove rust and other finer sediments.

Capacity and Using the Pitcher

The holding capacity of the Alkanatur pitcher is pretty decent. It’s able to hold up to 2.5 liters of filtered water, which is equal to about 10 cups of water at a time. It’s not large, but it’s enough for a small family. Moreover, the manufacturer has included a free bottle, which you can fill up with filtered water and place in the fridge.

The unfiltered water reservoir is slightly big too. It’s about half the size of the pitcher, so you won’t have to refill it frequently to get the pitcher full – you just need to fill it twice. There’s a small opening on the lid to allow you to fill the reservoir easily without taking off the entire lid, and it comes with a cover to keep dust and other particles from falling into the water.

However, the reservoir has an opaque turquoise color, so you can’t tell the amount of water left once you fill it unless you take the cover off, which is inconvenient.

Water goes through the filter fairly fast. It takes approximately 4 minutes to empty the reservoir, so it can take up to 10 minutes to fill the pitcher, which is relatively fast and means you won’t have to wait long to get the clean water. The speed gets slower over time, especially when the water is highly contaminated and the filter’s lifespan is almost up.

The spout doesn’t really offer a clean pour. The flap is quite clunky, even though it helps keep impurities from falling into the filtered water. It often doesn’t lift up when pouring hence it ends up partially obstructing the water flow causing some water to spill a bit while pouring.

You have to hold it with one hand to keep it open so that the water can flow out smoothly, which can be pretty inconvenient and challenging, especially when you have to fill a bottle.

The good thing is that the lid stays put as your pour the water. It doesn’t come off, like in most water filter pitchers. It fits firmly such that it can’t come off when you tilt the pitcher to pour the water, even when it’s tilted completely.

The only time it’s likely to come off is if you pour the filtered water when there’s still some water left in the top reservoir. Moreover, some unfiltered water can leak out of the top reservoir and end up in the cup you are pouring into, contaminating the clean water. You have to wait until all the water in the reservoir is filtered before you can pour the filtered water.

If the filter is not properly aligned and placed, unfiltered water can also leak into the pitcher and contaminate the already filtered water, especially when refilling the reservoir. You have to carefully situate it properly every time you fill the reservoir to ensure a watertight seal. As for the handle, it’s quite sturdy and comfortable to hold, so it doesn’t cause much fatigue when pouring water, even with the pitcher filled to the top.

Assembly and Filter Replacement

The assembly process is straightforward. In fact, there’s hardly any assembly to do as you only have to put in the filter, fill the reservoir, and wait for the water to filter through.

You have to dump the first filtered water at least four times before you can drink it because it will have some black particles of coconut charcoal and a fishy taste. After the four filtrations, the particles will disappear, and the water will taste great. The package includes the water pitcher, the filter, a water bottle, strips to measure the body’s pH, and drops to measure the pH of water.

Filter Replacement

Filter replacement is just as straightforward as an assembly. The whole top piece, which includes the lid and the cover, is removable. You just push it up to remove it, then take out the old filter, and put in the replacement. That’s all you need to do, but the filter has to be set properly through the hole to ensure a watertight seal.

The filtration capacity of the filter itself isn’t that large, but it’s okay for a water filter pitcher. It can purify up to 400 liters of water before requiring replacement. That’s about 106 gallons, which is the same as 3 to 4 months lifespan, with moderate daily use.

It’s about the same lifespan that most other water filter pitchers offer, but if your water is fairly clean, it can go up to 5 or even 6 months. However, if it’s very hard and has a lot of contaminants or your daily usage is high, you may have to replace it after 3 months or less.

The good thing is that even when the filter wears down, the alkalinity and ionization properties would continue to work, which means if you have another filtration system already installed and you just want alkaline ionized water, you can continue using the pitcher without replacing the filter.

The problem is that once the filtration ability is exhausted, the filter is already saturated with the impurities that it has captured – it becomes clogged hence significantly slowing down the speed at which water goes through it. In other words, it would take edges to get the pitcher filled with water compared to when the filter is new.

Another downside is that you can’t tell when it’s exactly the time to change the filter because there’s no indicator or any kind of water meter to let you know when the filter is used up. The only way to know is when it starts to get clogged. How fast this happens will depend on the quality of your source water, including how hard it is.

Besides changing the filter, the other maintenance you’ll need to do is clean the pitcher. Several users reported that a white residue tends to coat the pitcher, but this is not a widespread problem because it only affects those in areas where the water is very hard (with high calcium content). The filter does well to remove part of this calcium, but it adds magnesium, and it leaves the potassium that’s already present in the water.

The presence of these two minerals plus some small remnants of calcium can leave some whitish parts in the pitcher’s walls, making them opaque. However, the stain is not hard to clean. You just fill the pitcher with water and add a few drops of vinegar or lemon. In just one hour, the residue would have cleared out. In case you don’t perform this procedure and the residue becomes embedded, using hot water together with vinegar or lemon will remove it.

Build Quality

The design of the Alkanatur is similar to that of any other water filter pitcher. What sets it apart is the striking turquoise color of the top reservoir, which makes the whole unit look quite attractive. It would look great on any kitchen counter.

When it comes to size, the pitcher is relatively compact. It’s not really a cylinder. The form is a bit irregular, measuring 8.7 inches deep (including handle), 4.5 inches wide, and 11.5 inches high. It’s small enough to fit snugly in most refrigerator doors.

The overall build quality is decent too. The pitcher and the top reservoir are made using a thick plastic that seems sturdy enough to hold up to regular usage for a long period. It may not break easily when dropped.

The pitcher and the filter are made in Spain, while all the other materials used to make the unit have been sourced from within Europe, so you are assured of their quality. All the materials, including the plastic that makes up the pitcher, are free of Phthalates, Bisphenol-A (BPA), and all other kinds of endocrine disruptors – no toxins that can change the hormonal system are released into the water.

The handle is also well-made. It’s sturdy and attaches securely to the pitcher. It’s not likely to break over time, even with regular usage, plus it’s comfortable to hold, making it easy to carry the pitcher, which itself is not that very heavy when full with filtered water.

The only part that seems flimsy is the lid. The plastic is very thin and seems not durable at all. The plastic bottle that’s provided along with the pitcher is equally made of very thin plastic – it’s not really durable, and even the lid/cap doesn’t screw onto its opening properly.

Final Word

Overall, the Alkanatur 2.5 Liters Water Filter Pitcher offers great filtration performance. It’s an effective filter system suitable for filtering municipal water with high levels of chlorine and other organic chemicals. It’s able to effectively remove heavy metals and fluorine too.

It’s a perfect option if you want a water filter pitcher that’s able to alkalize and ionize your water, besides just removing contaminants. We would also recommend it if sodium is a great concern for you because it doesn’t add any sodium into the water, and in fact, it helps reduce the sodium that’s already in your source water.

The pitcher capacity is decent, and apart from the spout not delivering a clean pour, there’s no serious drawback to worry about. The whole unit is backed by a lifetime warranty, and the company’s customer service representatives are very helpful. They respond quickly when contacted, and they can be reached via email.
