The plastic components are food-safe and BPA-free to ensure they are healthy for the users.

H20Labs included a heating element with a 565W of power. It might not be as powerful as some other units, but it does a decent job of purifying the water. However, it will take up to six hours for a single gallon, which means you might need a bit of patience for the product to finish. The activated carbon pods ensure to “polish” the taste of the water and deliver consistent quality. The product also has an automatic shut-off feature, which helps you to use the machine overnight.

The product is pretty quiet, although it does make a fan-like noise when operating.

The quality and taste of water are up to the expectations since the unit includes a carbon filter. The machine will remove arsenic, bacteria, chlorine, copper, lead, sodium, mercury, viruses, and other compounds effectively. It is a shame that the carafe is made of plastic, but on the other hand, the manufacturer included a stop-and-serve feature that prevents any dripping, which is very convenient.

The best-quality components are inside the distiller. The heating element is hidden within a thermoplastic boiler made of food-grade materials. Thanks to that, mineral and scale deposits cannot coat the heating element and harm its performance. The manufacturer used an organic coconut shell for the activated carbon filter. The power output of the heating element is 750W, and it takes about 4.5 hours to process a gallon of water.

The appliance requires no assembly, and it is easy to use. Since it is light, you can also move it around if needed. Although a fan-delayed start enhances efficiency, the distiller can be somewhat loud (quieter than a dishwasher, but louder than a fridge).

Things to Consider

The first piece of advice we will give you is not to rush with choosing a water distiller. There are plenty of features to consider, and we will analyze all relevant factors in this buying guide. You will also learn more about the quality of distilled water, and why you should (or shouldn’t) use it. Finally, we answered the most common questions asked about water distillers. We hope that this section will provide everything you need to know about choosing the right device for your needs.

Why should I use distilled water?

Before you get to pick a suitable water distiller, let’s check out the benefits of drinking distilled water:

  • It will remove harmful compounds from the water, including pesticides, heavy metals, viruses, bacteria, and other pathogens and contaminants. Depending on the product, you can expect 99.99% of purity when using a water distiller.
  • Minimizes the risk of waterborne diseases by removing viruses, bacteria, and other microbes causing them.
  • Distilled water might be beneficial for detoxifying your organism as it can absorb and help in eliminating toxic compounds.

Before you decide on whether you want a water distiller, be aware of these disadvantages of using it:

  • Distilled water is free from harmful chemicals, but also minerals that the human body needs, such as magnesium and calcium. That is why you have to stick to a healthy diet and obtain those minerals from other sources.
  • The taste might be weird, especially at first. Some users describe it as “flat,” and that taste might not meet everyone’s preference. However, it is important not to let it affect the quantity of water you consume daily, which should be at the recommended levels.

8 Best Water Distillers - Improve the Quality of the Water!How to pick the best water distiller?

If you are wondering how to choose a water distiller, it is important to consider both design and performance features. The crucial thing might be water quality, but that is something you can expect from all top-rated units mentioned in our list. That is why we will focus on different features that might help to pick a device that meets your specific expectations. If you are ready to start your quest for finding a suitable water distiller, these are the factors to consider during the process!


The dimensions of your preferred water distiller are not only about aesthetics. It is important to purchase a device that can fit on your countertop. Some units, such as the VEVOR Water Distiller, are compact and easy to place anywhere. The compact size also affects the weight of the unit. The smaller it is, the lighter it will be, and that can affect the portability of the entire product.

When choosing a distiller, start by checking out its dimensions. Next, compare them with space where you plan to place the machine and make sure it fits.

If necessary, consider the weight of the machine, too. You can also keep in mind the design since picking the right shape and color combination depends on how well the distiller fits with other items in your kitchen.


The crucial component of a water distiller is its heating element. These are in charge of distilling water, which is why you should ensure they are of high quality. Apart from that, it is important to check the performance of the heating element. Its power usually varies from 500W to 800W. If you are looking for fast results, choose distillers like the Waterwise 3200.

The power affects how quickly you can expect the water to be distilled. Up to a certain extent, it might also influence the quality of purified water. However, you should also note that power is directly related to energy consumption. The most powerful units out there might utilize more energy than low-powered ones, although that depends on a particular product.

8 Best Water Distillers - Improve the Quality of the Water!Distillation rate

The distillation rate describes how much water a distiller can produce in a specified time. The majority of manufacturers mention how many hours their machine takes to deliver a gallon of water. Most units take about four hours to deliver a gallon, and that is the average distillation rate. However, it will vary on a product. Some devices, such as the Pure Water Mini-Classic CT, are faster and can complete a cycle in 3.5 hours, but they don’t deliver an entire gallon in the process. Up to a certain extent, the power of the device affects its distillation rate. You can also consider units with a stop-and-serve feature, such as the Waterwise 3200. These can ensure you don’t have to wait for the entire cycle to end to drink distilled water.


It is important to establish a difference between the two types of components used in water distillers. The first ones are those that come in touch with the water you drink, and the other ones don’t.

You should aim for units that include food-grade components, including carafe and other parts that touch your water. Otherwise, the harmful compounds from those parts could affect the quality of water and reduce purification results.

When it comes to interior components, most manufacturers go with stainless steel or high-quality ABS and plastic. The thicker the housing, the better the sturdiness and durability of the product.

As for the materials used for the carafe, you can choose from glass or plastic. Since you will be using the pitcher to pour the water, it is essential that these components are made of food-grade materials.

Water collection

Each distiller device comes with a water collection system. It is a jug, jar, or carafe, that collects the water after the appliance purifies it. The capacity of the container might vary, but it is usually from 0.5 to 1-gallon to ensure the overall device size remains compact.

The material that the manufacturers use is either glass or plastic. While glass is a more elegant and durable solution, it is also prone to breaking. If you drop it on the floor, the chances are you can’t use it anymore. On the other hand, plastic containers should be made of food-grade materials. That means they are free from BPA and other harmful compounds that could affect your health and minimize the effects of distillation. The lid of the pitcher should fit tightly on it, but also be easy to open.

8 Best Water Distillers - Improve the Quality of the Water!Filtration system

The filtration system is another component that can contribute to the success of the purification process. The distillation removes minerals and other harmful compounds, but it is not effective for VOCs (volatile organic compounds). These include chlorine, which is frequently found in tap water, as well as chloroform and other trihalomethanes (THMs).

If you want to purify the water from these components, you can consider using activated charcoal filters. Some units, such as the Megahome Countertop Water Distiller, are equipped with this feature.

It is important to note that filters last for a limited time. Some of them have a very long lifespan, but they might become less efficient as time passes.


When using electronic appliances, safety should be your primary concern. The essential feature you should look for is automatic shut-off. That enables you to turn on the unit and head to sleep or leave the house while it is working. Fortunately, most countertop water distillers come with this feature.

Another useful addition is overheating protection. Each distiller comes with a heating element that purifies water. If something goes wrong, and the element goes over the allowed temperature, the overheating protection feature will ensure to detect the problem and turn the unit off. That way, it minimizes the odds of a fire hazard, or the device getting destroyed.


The warranty for water distillers is usually around 12 months. However, that doesn’t mean the product can’t last long, especially if you replace filters and maintain it optimally.

The duration of the warranty will depend on the manufacturer. Another thing to note is that the guarantee might not cover the entire machine. For example, the Pure Water Mini-Classic CT comes with a 15-year warranty on stainless steel components, which is quite impressive. Additionally, some manufacturers require you to buy a warranty separately for the product.

8 Best Water Distillers - Improve the Quality of the Water!Prices

The cost of water distillers can vary from around $100 to more than $300. In the budget-friendly pricing category, you can choose affordable units like the VEVOR Water Distiller. They deliver decent power and speed, and distillation results should also meet your expectations. However, the durability of filters and other components might be slightly lower than with more expensive models. The price of cheap water distillers is from $100 to $150.

If you are looking for an average home water distiller, be ready to invest from $150 to $300. The quality and features depend on the unit, but reliability and consistent performance are to be expected. If you choose wisely, you can find some true gems in this category, such as the H2O Labs Best-in-Class 300SS.

Finally, you can also go with premium units, such as the Pure Water Mini-Classic CT. These can cost from $300 to more than $500, and they often come with carefully selected food-grade components that are very durable. These devices optimize aesthetics and functionality and ensure ease of setup, use, and maintenance.


Here is an overview of the water distiller cleaning process:

  • Unplug the device from the power socket and take off the boiling chamber’s lid. Add a couple of tablespoons of white vinegar or sulfamic acid to the chamber.
  • Swirl the solution for up to 15 seconds and leave it for several hours or overnight.
  • Empty the chamber. Now, rinse it out by filling with clean water and swirling for 15-30 seconds. Repeat the process if necessary, it is essential to remove all residue.
  • Use a cloth to wipe the chamber, and you are ready to go.

The frequency of cleaning depends on the device. However, you should clean the distiller at least once every couple of months. Make sure to consult the instructions to see what the manufacturer recommends for your specific unit.

You can try using pre-heated water to speed up the process, but you shouldn’t expect wonders. Instead of trying to accelerate the filtration rate, consider getting a more powerful unit. Premium water distillers should be able to distill the water at a somewhat faster rate than entry-level ones. Here is another trick that you can use if you are tired of waiting for the water distiller to end. How about activating it before you head to sleep or go to work? You can turn it on and go to sleep or leave the house. Once you come back, you will have distilled water ready to use.

The most common type of water that people purify is tap water. However, you can also consider purifying water from rivers and wells or even bottled water. The important thing to note is that the efficiency in purifying the water will depend on the distiller you use. That is why you should avoid using water from unverified sources, such as lakes or rivers. Some devices can purify it completely and make it suitable for drinking, but some harmful compounds might remain in the water. Water distillers are great for purifying tap water and removing pathogens and other harmful components.
