The Best Water Distiller Machines for Purifying Your Water

Writen by Ronald Brown

Fact checked by Natalie Bridges

best water distiller

Households use the best water distiller because they want to purify water and make it safe for drinking. It is a substantial investment that can maintain the good health of families worldwide. This machine is easy to set up, use, and support. It is also functional and offers convenience. However, you can find many of these home distillery water distillers. In this case, selecting one right for your requirements and preferences is hard.

It can be hard to pinpoint which product best suits your family’s needs among various water distillers available on the market. Therefore, you’d find it useful to learn some of the essential features a high-quality distiller would normally have.

  • Materials: Food-grade stainless steel is a must for the water distiller’s boiler chamber to prevent contaminating the water with aluminum or plastic components. The water collection chamber should be glass or stainless steel because they do not leach chemicals and undermine the water’s purity. However, these materials are often pricier than plastic. Some households might be willing to compromise by increasing recontamination risk to save a few bucks.
  • Distillation Speed and Capacity: The average water distiller takes 4 to 5 hours to produce a gallon of pure distilled water. Running continuously, it can filter about five to six gallons in 24 hours. You might want to consider your water needs to choose the top-tier distiller for your family.
  • Boiler and Distillation Capacity: Water distillers have two essential components: the boiler and the distillation or collecting chamber. The smaller these components, the more frequently you must add water to distill. It should not be an issue if you are alone. However, it can become a problem if you need distilled water for the whole family.

Worry not now, as in the following are the top recommendations on the market. Let us begin with the reviews of the water distillers to choose from and use if you’re ready.

Top 9 Water Distiller Reviews

1. Mophorm Pure Water Distiller

Homeowners and families looking for the most convenient countertop home water distiller should put the Mophorm Pure Water Distiller at the top of their list. High efficiency, this product can produce 34-44 ounces of pure water an hour. That is an impressive 6.375 to 8.25 gallons over 24 hours.

I appreciate this distiller’s elegant design. Families will never feel ashamed to put this device on their countertops or tables. I like its style better than VEVOR, and I’m also impressed with how easy it is to operate the product. If I must reset it, I simply need to press a button instead of having to unplug the device from the outlet.

This home water distillery system features food-safe stainless steel for its 1.1-gallon boiler and other interior components, although its exterior is BPA-free plastic. This combination allows the company to offer a safe and reliable water distiller without jacking its price.

This distiller’s safety and control features are also impressive. For example, it automatically shuts off if the sensors detect a rise in water temperature above 239 degrees Fahrenheit. Households will never worry about burning themselves because this device has an integrated overheating protection system.

However, I have one issue with this tabletop water distiller: I cannot use it if there is a power outage because it only runs on electricity, and there is no backup power source either.

Despite these concerns, I still recommend this water distiller to families who want a dependable system for purifying their water.
What We Like
  • 6-gallon daily distilled water output per day
  • 1-gallon boiler capacity
  • Food-safe stainless steel boiler chamber
  • Intelligent control features for users’ safety

2. CO-Z 4L Stainless Steel Water Distiller

The CO-Z distiller for water boasts a sleek and classic design. Made from a combination of stainless steel and glass, it earns a spot as one of the most beautiful American water distillers in the market.

Not only that, but the CO-Z water distiller is also easy to use. The manufacturer created this home water distillery machine with comfort and practicality in mind. You’ll just need to press a single button, and voila, you will get distilled water in no time.

Moreover, the CO-Z water distiller is also easy to maintain due to its stainless-steel exterior. As such, you don’t have to replace the filter cartridges. You just need to wipe the device whenever it gets dirty.

What I like the most about the CO-Z water distiller is its fast preparation time. Compared to others, this distilled water maker can effectively distill a quarter gallon of water per hour. With this, you can necessarily get 6 gallons of distilled water every day without needing to buy bottled water.

Another thing I like about this product is that it’s also safe to use. The CO-Z water distiller automatically switches off when it reaches and exceeds a temperature of 300 degrees Fahrenheit. With this, you can avoid any potential accidents as well as increase the lifespan of your device.

The CO-Z water distiller also comes with surge protection. Moreover, it’s also safe since the water distiller’s container is made from plastic that is food-grade and BPA-free. Hence, you wouldn’t have to worry about anything.

What I didn’t like about the device is that it’s kind of bulky as it weighs at about 9.6 pounds. Nonetheless, the CO-Z water distiller is still portable and easy to carry around.
What We Like
  • Safe to use
  • Easy to clean and maintain
  • Stainless-steel exterior
  • Fast water distillation rate

3. Best-In-Class Stainless Steel Water Distiller

Value for your money, this portable water distiller by H2o Labs, is classified as the best overall water distiller in its batch. It has been tested and assessed for its top-notch dependability, user-friendliness, functionality, and quality.

What it can offer you by the end of every cycle would be water that is pure, clean, and better tasting that your household would end up drinking more than usual.

You will be amazed by the exclusively activated carbon pods that are incorporated in this water distiller. It is designed to last twice as long, and it contains three times the filtering components.

Hence, the water is pure and at the same time free of any contaminants because this system also has the most effective VOC removal process among all distillers.

Indeed, you would see right away notice how aesthetically beautiful this product is. It looks elegant to be rightfully placed on your countertop, but at the same time, you’d also appreciate the materials that were used to create such an excellent product.

The whole steam chamber and the whole condensing oil are made of 100% stainless steel, Grade 304, which is the most versatile and used of all stainless grades. All the plastics that are incorporated are BPA free and food safe. Additionally, the H2o stainless steel water distiller has included the Porcelain Nozzle insert, so you are sure that your pure water will never touch the plastic or the metal.

Contrary to practice where a more prominent heating element is deemed more effective, this stainless steel distiller can boil the water faster than preferred. Thus, it can cause the water to mix with VOCs and other water impurities. This brand uses an optimal-sized 565 heating element to ensure that water is boiled at the right speed and temperature.

Some slight drawbacks here are during the process. However, it is not obnoxiously loud, it does emit a slow hum like an electric fan on low power. You’d need to manually take tap water from the tap and fill the carafe and wait for several hours for your pure water. So, it is not instant water.

Indeed, this is a great addition to your household or office. It is straightforward to use and maintain, and its output water is superb. This is highly recommended and worth the money.

What We Like
  • Easy to use
  • An integrated optimal sized heating element
  • Quality materials used
  • Plastics are BPA free and food safe
  • Has exclusive carbon filter pods
What We Don’t Like
  • Emits a faint hum
  • Wait time for the processing

4. VEVOR Water Alcohol Distiller

An issue with Mophorm is its electrically operated design. It is not a concern if we do not have occasional power outages in our community. I could also not bring it to the campsite and distill water in the campfire.

Unsurprisingly, many outdoorsy families love the VEVOR Alcohol Stainless Steel Water Distiller. This distillation system is perfect for campers, backpackers, fisherfolk, and families living off the grid.

It does not require electricity to distill water, although families can place the distiller atop a ceramic electric heater. It’s also compatible with stovetop burners, induction cooktops, or coal-fired stoves. My favorite is purifying water with this pot-like device in an open fire pit while roasting skewered game meat and marshmallows.

I was curious about this water distillation system’s design, which is almost similar to a double boiler. The only difference is the upper chamber comes with high-quality copper coils to help condense the steam from the boiler compartment.

Every component is food-safe, including the silicone hose and stainless steel body. I will never worry about plastic chemicals leaching into my distilled water. More importantly, I know this water distillation kit will last many years.

Distilling water is also a breeze because the thermometer has Celsius and Fahrenheit markings. The O-seals form an airtight mechanism to prevent steam from escaping. And while I am unsure how much water this product can distill per hour, I am still happy its boiler can accommodate three gallons.

Although this non electric water distiller has a built-in thermometer, there’s no mechanism to automatically shut off power to the heating elements—I must do it manually. Moreover, some folks might find its open-cooling design a hassle because one must keep the condenser coils cool by placing ice.

Off-grid households will love this water distillation unit. It gives them a chance to enjoy purified water without electricity.
What We Like
  • Impressive three-gallon capacity
  • All food-grade materials
  • Compatible with electricity and various heat sources

It’s easy to use as you just need to push the entire process’s button to start. The water distiller is also quiet and produces only minimal noise when in use.

Moreover, this automatic water distiller also comes with the necessary safety features. For one, it automatically turns itself off when it completes the distillation process. Aside from this, the device also has ventilation holes and an integrated fan to prevent the distiller from overheating. With such a function, you can protect your device, prolong its lifespan, and avoid any potential accidents.

The ROVSUN water distiller requires little effort to set up and maintain. Due to the distiller’s large openings, you can quickly access and disassemble the parts for easy cleaning.

Another thing I liked about this device is that it’s compact. Aside from using it at home, users have taken the ROVSUN water distiller on vacations and even used it in RVs or during camping.

The only drawback of this product, however, is that the distilled water might taste of rubber or plastic from the first use. Luckily, this goes away quickly.

With its prominent glass container, the distillation water filtration process can produce about 3 liters of distilled water every 3.5 hours. As such, it’s great to have, especially when you have a small- to medium-sized family. Moreover, with the significant volume, you wouldn’t always have to refill.

What Is The Top-Tier Water Distiller/ Who Is This For


When it comes to water purifying systems, most of us are familiar with the usual processes such as reverse osmosis, UV purification, distillation, desalination, and the like. However, while these may be effective, these systems are not precisely home-friendly. Many water purification systems tend to be bulky and take up a lot of space, which might not be ideal for some homeowners.

Luckily, modern technology has enabled us to purify our water in a more convenient and straightforward way. One of these methods is through using a water distiller.

Simply put, a water distiller is a machine that purifies your water supply using the distillation process. It relies on steam to separate and remove all the particles, contaminants, VOCs, and other impurities lurking in your water. After that, the machine then recondenses the steam into a small container as clean water.

However, unlike the more significant systems, water distillers tend to be small and portable. Most of them only weigh a couple of pounds and are designed to be sleek and compact.

As such, they are ideal to use if you have limited space or when you are just living alone or have a small family. Many water distillers are designed to fit into small countertops for the user to save space.

There are even some water distillers that are so small and light that some users also bring them with them on vacations and outdoor activities. As such, it’s not entirely uncommon to see these devices in campers, RVs, and other motorhomes.

A distiller is also quite convenient since they are automatic. You’ll just need to push a button for them to work.

Moreover, they are also quite safe to use as they come with the necessary safety features. As such, you wouldn’t have to worry about using them.

How Does It Work

Water distillers rely on the distillation process to purify your water system. They usually consist of the following parts: a heater, a thermal baffle, a cooling system, an activated carbon filter, and a storage tank.

How this distiller works is that you first place your unfiltered water into the device. Once you push the button, the water distiller’s heater will immediately heat your water until it reaches the boiling point.

This step is where the purification process begins. As the water is being boiled, it is also being cleansed from volatile organic compounds and other bacteria found in the water. It also physically separates the water from all the particles, sediments, and other contaminants as it turns into steam.

Once the water turns into steam or vapor, it is then collected and drawn into the cooling coils of the distiller until it reaches the cooling chamber. The cooling chamber contains a cooling system to lower the steam’s temperature.

As the steam cools, it slowly goes back into a liquid state. The “purified” water is then collected and stored in a water container for the user to use.

Some water distillers come with a carbon filter for further filtration. These filters separate any remaining impurities found in the water after the distillation process.

Advantages And Disadvantages Of Using A Water Distiller


A water distiller is another way of filtering out and purifying your water supply. However, like all products, it also has its fair share of advantages and disadvantages. This section will list all of them down.


Compact and Portable

Unlike other water purification systems, water distillers are small and portable. Most of them are designed to fit on top of countertops and small spaces. Thus, they are quite ideal if you have a small space or are living alone or with a small family.

There are even some water distiller models that you can bring along on your travels or vacations. As such, it’s not uncommon to see these units in RVs, campers, and motorhomes.

Easy and Safe to Use

Water distillers are also easy to use and maintain. For one, most of these models are automatic. As such, you’ll only need to push a button for it to work.

They are also easy to maintain since most units are easy to disassemble for cleaning. There are even water distillers with self-sterilizing properties, so you don’t have to put that much effort into cleaning.

Water distillers are also safe to use since they come with safety features. Many distillers in the market come with safety switches that automatically turn the device off once the distillation process is over.

There are even units that protect the device from over-surging and overheating. Not only does this prolong the lifespan of your device, but it also protects you from any potential accidents and problems.

Constant Clean Water Source

Of course, having a water distiller means you’ll have a constant supply of distilled water, which is said to have a lot of health benefits.

Distilled water is considered the “purest” since it does not undergo any artificial filtration. As such, you wouldn’t have to worry about any contamination or re-contamination.

Water distillers also produce “clean” and “pure” water since it filters out particles, sediments, contaminants, VOCs, and other impurities found in your water supply. With this, you wouldn’t have to worry about any diseases or illnesses.


Limited Supply

Water distillers can only purify a limited amount of water for a certain time. As such, you might need to refill constantly, or you’ll have to store purified water if you plan to use a large volume.


Water distillers also use up a lot of energy. Hence, you might see a surge in prices in your electricity bills.

Buying Guide


Water distillers are a convenient and portable way to obtain a constant supply of clean and distilled drinking water. There are quite ideal to use among individuals or small families or when you have a limited amount of space.

Due to their popularity, there are numerous models of water distillers available in the market. This plethora of choices can make it quite challenging to choose, especially when you are a beginner. However, you don’t have to worry. This section will list down all the factors you need to know and consider when you are out there.

Capacity and Speed

One of the factors you need to consider is the water distiller’s capacity. This talks about the volume of water the device can distill in a day.

It’s essential to determine how much-distilled water you are going to use in a day to determine the capacity you need. As such, you’ll have to track your water usage.

You’ll also have to consider the device’s distillation speed, which refers to how much it can distill at a specific time. The fastest speed you can find in the market is a gallon in just 2.5 hours. However, most units tend to produce a gallon in 4-5 hours.


Water distillers are made of numerous materials. Stainless steel models are quite popular in the market and are quite durable. If you are interested in these types, ensure that the material is of high quality. Ensure that the distiller comes with a stainless boiling tank and that all components that touch water should be made of high-quality stainless material.

There are also some water distillers made of plastic. If you are into this, make sure that the unit is BPA-free. Moreover, choose one that has a high-quality glass water container.


Water distillers also come in manual or automatic versions. Manual types need to be emptied and refilled before they can distill water. On the other hand, an automatic distiller only needs to be attached to an existing water line. Once you push the button, the machine will automatically distill the required volume.

Some water distillers come with temperature adjustment buttons as well as timers and LED indicators. This makes it very convenient and easy to use. Moreover, it’s most suitable to choose a water distiller that comes with safety features.

Energy Consumption

Water distillers run on electricity for them to work. As such, it’s essential to also look at how much energy your water distiller can consume. Otherwise, you might have problems coping with your energy bills.


Some water distillers come with filtration mediums such as activated carbon and the like. With this, the device is effectively a combination of both a distiller and a water filter. Not only does this further purifies your water, but it also helps in improving the water’s taste. As such, if you dislike the taste of distilled water, it might be top-quality to purchase a distiller with a filtration medium.

Frequently Asked Questions (FAQs)

What contaminants does a water distiller remove?

The Centers for Disease Control and Prevention says a water distilling machine is as effective as reverse osmosis technology in removing bacteria, protozoa, viruses, and chemical contaminants.

To elaborate, like RO systems, a distilled water purifier can remove nearly everything from the water. It has been proven that distillation can eliminate lead, nitrates, iron, chlorine, chloramines, magnesium, sodium, calcium, iron, manganese, fluoride, radionuclides, and other chemicals.

A distiller for a dental office, medical, home, and commercial applications can also remove E. coli, Shigella, Salmonella, Campylobacter, Giardia, Cryptosporidium, Rotavirus, Norovirus, Hepatitis A virus, and Enterovirus species.

However, a distiller’s contaminant removal capabilities depend on the chemical or substance’s boiling point. It is worth noting that distillation heats the water to its boiling point to create steam or vapors for condensation.

Molecules with a boiling point lower than water can also vaporize and condense with water molecules. Examples of such compounds are toluene, benzene, other VOCs, volatile solvents, and pesticides.

Keep in mind that these impurities can have serious implications for CPAP patients because they can inhale these substances through the humidifier.

Is distilling water better than boiling?

Yes, distilling water is better than boiling. Although the process might be similar, distillation requires steam condensation and collection in a separate container.

Big and small water distillers heat the water to its boiling point. The water then turns into steam and rises from the water’s surface. The steam travels to a tube where a temperature gradient lowers the vapor’s temperature and converts it back to liquid form (condensation).

The process leaves contaminants with a higher boiling point than water in the boiler compartment. Meanwhile, the condensed (distilled) water collects in a separate chamber of the kitchen distiller.

Boiling does not do this. Steam evaporates or condenses back into the boiler. Continuous boiling also vaporizes other contaminants with a higher boiling point than water and returns to the water if the temperature cools.

Hence, you can say distilled water is purified water, while boiled water is not.

Can you turn tap water into distilled water?

Yes, you can turn tap water into distilled water. You do not even need a high-tech water distiller recommended by NYT Wirecutter or some other online platforms. You only need two cheap pots, tap water, ice cubes, and a cooktop for this setup.

Fill a large and sterile pot with tap water and place a clean smaller pot inside, ensuring ample space around the latter (sides, bottom, and top). Turn the burner to medium-high heat (about 180 to 200 degrees Fahrenheit). Next, cover the larger pot with the lid inverter to allow condensation to drop into the smaller pot.

Place ice cubes on the inverted lid to help with condensation. As steam begins to form and rises to the lid’s inverted surface, the cold cover will transform the vapor back into water and allow it to glide and drop into the collection pot. The ice will melt, so you must place new ice cubes on the lid.

Eight cups of tap water should give you about 1.25 cups of distilled water. That should be sufficient for personal consumption.

How long can distilled water be stored?

Distilled water can be stored indefinitely, provided you observe the correct distillation and storage procedures. To be specific, you need to keep the water in a cool place and away from chemicals. Make sure that the closing lid is airtight to keep contaminants in the air from reaching your drink.

So don’t worry if you notice an expiration date on your distilled water bottle. As pointed out by Consumer Reports, in some states, it’s required by laws that bottled water has an expiration date. But this doesn’t mean that the drink is no longer consumable past this point.

What are the most trusted water distiller brands?

The brands, including CO-Z, Megahome, and ROVSUN, are the most trusted of all in the industry. No wonder, as they’re reliable and committed to offering quality and heavy-duty water distillers. When comparing different items, check them out to ensure that you’re dealing with those serious about making their customers happy and satisfied.

Is it safe to drink distilled water?

It is generally safe to drink distilled water, but some people do not like its taste. They’re saying that it is less flavorful and has a flatter taste than bottled waters. But regarding safety, distillation is an excellent process because it can remove impurities from water. At the same time, though, it can remove minerals, too. That is why many practitioners do not recommend drinking it for a long time.

Are water distillers worth the money?

Compared to buying bottled water, distilled water made by a water distiller from home is worth the money. In the end, it can pay for itself because you no longer need to buy bottled distilled drinking water. So, if you want to save money while also conserving nature, you can consider getting a distiller machine and using it to create purified water.

Do water distillers need filters?

You have the choice to use filters for a water distiller. But generally, it can be better to use one because it might be able to remove volatile organic compounds, based on what you selected. A filter can protect you and your loved ones from the natural and mineral substances that can get into your water.

How much does a water distiller cost?

There is no one answer to this question. One can be pricier than the other is. That is why it pays off to determine your budget before comparing the different water distillers. In the process, you can save time and effort than browsing all the products to find.

How to set up & use?

The distilled water machine is easy to use. Many of those featured here, for instance, is very straightforward. You only need to push a button and leave it. The distiller will automatically turn off when done. The assembly and cleanup are also not hard. Just refer to the user manual for the specific instructions.

How to care & clean?

Regularly, you need to clean the machine so that it can prevent descaling. It can also prevent your device from having mold, which would otherwise affect your unit’s performance. You must be consistent in cleaning your machine so that you can extend its lifespan. For some products, manufacturers recommend cleaning every three or four months.
