The Pure Water distiller stands at just under 16" tall and is about 14" wide

Our experience with the Mini Classic

We’ve used the PureWater Mini Classic Countertop Distiller for over three years now. It’s turned on once a day and takes about three and a half hours to fill the glass carafe, which is just under a gallon. The water is transferred to a larger glass container that we store in the fridge. And although the carbon filter helps nullify the flat water taste, I’ll add a pinch of sea salt and lemon to reintroduce more electrolytes.

Replacement parts and maintenance

I clean the boiling tank once daily after each use with baking soda and vinegar and use a soft sponge to scrub. The residue comes right off.

PureWater recommends replacing the carbon filter every three months, but I like to replace them a bit sooner than that. Around the 60-day mark, I start to notice that the taste of the water becomes more flat.

I haven’t yet needed to replace any of the o-rings and gaskets but we have extra stored away when needed.

TDS measurements

Our tap water was reading at around 340 PPM with the TDS meter prior to distillation. The Classic Mini brings the TDS level down to 1 PPM.


Our recommendation for the Mini Classic

If your primary use for the Mini Classic is drinking, we'd recommend storing the distilled water in a glass container in the fridge. After the distillation process, transfer the distilled water from the collection jar and into a glass container, preferably with a spigot, for easy access. Glass will prevent any leaching of chemicals from the container into the water. Add a pinch of sea salt and a squeeze of lemon to enhance the flavor.

  What we like most about the Mini Classic

With an 800-watt heating element, the Pure Water distiller is about to distill at a rate of 0.8 gallons every 3.5 hours – making it the most efficient distiller on this list. But its efficiency isn't necessarily what makes it our favorite distiller. The confidence in its build quality and design is what makes me realize that the Mini Classic will outlast many other cheaply-made distillers.

And not to mention a 15-year warranty on stainless steel and two years on electrical, this American-made distiller offers one of the best guarantees for any distiller on the market.

  What we don't like

The Pure Water distillers are certainly more pricey than most other distillers. But with a reputation as rock-solid as theirs and a premium product to back it up, it's well worth the price tag.

  What we don't like

For as powerful as it is and with as much energy as it uses (900 W), a warranty longer than a year might have been better.

  Is it for you?

If you need a powerful distiller that will provide a large amount of water fast, few are more powerful than Rovsun's 900 Watt distiller.

What to Consider When Choosing a Water Distiller

Clean kitchen

The distillation process works the same way regardless of whether it's done with a home countertop device, an industrial distiller, or naturally through the hydrologic cycle. It's all about evaporation and condensation. When it comes to purchasing a distiller for your home, there are other underlying factors that you may want to consider. Things like size, manual vs. automatic, and capacity all play a role in how much distilled water you'll be able to use. Here are some of those factors.

Manual vs. Automatic

The most common type of residential distillers are countertop distillers. These are smaller devices that typically produce distilled water one gallon at a time, and water is poured into them manually. The entire process can take a few hours, but once it's complete, water will need to be poured into the distiller again in order to start another cycle. In most situations, a countertop distiller is sufficient to provide individuals, couples, or small families with adequate distilled water.

For larger families or those requiring more distilled water regularly, a countertop distiller might not provide water at a fast enough rate. Automatic distillers connect directly to the water line so that water feeds into the system. A storage tank keeps distilled water in reserve, ready to be used whenever needed. Some automatic distillers have features like automatic drainage and the ability to divert water into other appliances like icemakers and refrigerators.


The type of material used to make the distiller is an important factor to consider. Although the distillation process results in water free from impurities and contaminants, the material used to make the distiller could leach chemicals into the water during heat, rendering the distillation process useless.

Stainless steel or glass are typically preferred as they do not leach chemicals into the water under heat during the distillation process. You will have to make sure that they are labeled as food-grade materials, which ensures that they are up to the cleanliness standards after the manufacturing process. Stainless steel and glass are also easy to clean.

Although plastic is cheaper, it is less preferred. If you opt for plastic, make sure to look for BPA-free plastic distillers, as plastics made with BPA will leach the same chemicals you were trying to remove from your water into the distilled water. It is recommended, though, to steer clear of plastic distillers. Distillation involves extreme temperatures, so contact with water with plastic materials can compromise quality and taste as well.

Distillation speed

Another important factor to consider is the rate at which distilled water can be produced. Distillation is a relatively slow process. An average water distiller produces 4 to 6 gallons per day, with an average flow rate of 1 gallon per 5 hours.

Physicians recommend drinking about one gallon per day. So, for a family of 4 members, a distiller with a flow rate of at least 1 gallon per 5 hours will be preferred.

For those requiring more distilled water than the common rate of 1 gallon per 5 hours, consider using an automatic distiller that connects to a water line and has a storage tank. Automatic distillers with a storage tank can produce a continuous amount of distilled water.


As with many other products, warranty is also an important factor to consider. Water distillers may have different warranties for the machine and electrical components or one warranty for the entire unit. The standard warranty offer is one year for the entire unit, but it may differ accordingly. Some manufacturers, such as Pure Water, have an excellent warranty of 15 years for stainless steel parts and two years for electrical parts.

Total Holding Capacity

The total holding capacity is the amount of water that can be stored after distillation. Manual water distillers usually use a plastic or glass jar with a total holding capacity of 1 gallon, whereas automatic water distillers can usually store around 3 to 10 gallons of water in a stainless-steel reservoir. Some prefer to transfer the distilled water to a glass container to be stored in the refrigerator.


Most water distillers use activated carbon post filters to reduce any residual tastes or odors that might have been pushed over during the distillation process. They are most effective when placed after the distillation process before the water enters the reservoir. Carbon post-filters also remove any volatile organic compounds that can be evaporated along with water, ensuring highly purified water as some impurities may have lower boiling points than water.

Testing/ NSF Certifications

While no federal regulations for residential water treatment exist, independent organizations such as the NSF (National Sanitation Foundation) and the ANSI (American National Standards Institute) were created to establish voluntary national standards.

NSF/ANSI 62 is the particular standard that covers material quality, system design, construction, and performance expectations for drinking water distillation systems and their components. Its goal is to reduce chemical contaminants in drinking water and address microbiological threats like bacteria, viruses, and cysts. Home water distillers labeled with NSF/ANSI 62 have met these standards.

Energy Consumption

Most home water distillers operate at around 110-120 volts and consume around 500-800 watts, which is common for most US appliances.

It typically requires about 3 KWH to produce 1 gallon of distilled water. With an average electricity rate of 10 cents per KWH in the US, that equates to about 30 cents of energy costs per gallon. Many distillers boost energy efficiency with automatic shut-off features when not in use.

Benefits of Distilled Water for Domestic Use

It is Purified Naturally

The primary benefit of having a water distiller at home is having the ability to produce clean, contaminant-free water on demand. As distillation replicates the hydrological cycle, it is a natural method of water purification. Because distilled water contains nothing but the H20 molecule, some like to add a bit of sea salt or Himalayan pink salt to replenish some lost minerals.

Cheaper Alternative to Bottled Water

Investing in a high-quality water distiller may require a significant upfront cost, but the long-term benefits are substantial as you gain the ability to produce distilled water at virtually no ongoing expense. Over time, this translates into substantial savings compared to continually purchasing bottled water.

This might be proven when comparing your annual expenditure on bottled water versus the initial cost of a water distiller.

Potential Detoxification Benefits

Distilled water has the tendency to latch onto other chemicals due to its purity. This means that potentially toxic chemicals in the body can be absorbed by distilled water when consumed, essentially causing a detoxifying effect. Distilled will also latch onto beneficial minerals in the body such as sodium, magnesium, and potassium. Be sure to maintain an adequate diet of nutritious and mineral-rich food when consuming distilled water.

It is free of all contaminants

Because water distillation removes all contaminants other than the H20 molecule, there will be nothing harmful remaining in the water. This means all of the following contaminants will not be present in distilled water:

Nitrates or Nitrites

Nitrates and Nitrites may be found in tap water and groundwater. Nitrogen fertilizers used to enrich soils may lead to traces of nitrates in groundwater. Human and animal wastes can also contaminate groundwater with nitrate. Nitrates and Nitrites are dangerous to humans, especially children and the elderly with weaker immune systems. Ingesting large quantities can lead to lethal accidents as well.


Chlorine is a disinfectant added to drinking water to remove microorganisms such as bacteria and viruses and is used in most public water systems. However, too much chlorine in the water supply can lead to health complications and should be avoided if possible.


Although some microorganisms are beneficial to humans, many waterborne microorganisms are extremely harmful. Distilled water is free of all microorganisms.


Industrial waste often leads to the contamination of groundwater with Barium, which may eventually make its way to our tap water. According to a study that discovered a link between Barium and high blood pressure in lab animals, Barium can cause heart problems.

Other contaminants

    • Physical contaminants such as sand and silt
    • Heavy metals, such as lead and mercury
    • Fluoride
    • Arsenic
    • Radioactive elements
    • Pesticides and herbicides
    • Pharmaceuticals

What is Distilled Water Used For?

Because distilled water is pure and void of any minerals or contaminants, it is the preferred form of water for a variety of uses. Here is a list of ways distilled water is used:

  • Adding to a Humidifier
  • Drinking
  • Medical Sterilization
  • Vehicle Maintenance
  • Canned Vegetables, Fruits, and Legumes
  • Cosmetic Products
  • Home Aquariums
  • Ironing
  • Watering Plants
  • Cooking and Baking
  • Washing Hair and Skin
  • Baby formula

Types of Water Distillers

countertop distiller silver

Countertop Water Distillers

These are usually the most basic types of water distillers. A common type is a gallon-sized distiller that you can easily set up on your kitchen counter. They are simple to use and maintain. To use, you have to pour a measured quantity of water into the boiling chamber; then, the distillation process occurs over the course of a few hours. Water is collected and filtered into the reservoir, ready for use.

Automatic Distillers

As opposed to countertop distillers that require water to be added manually, automatic distillers connect to a water line that feeds the system with water at a steady rate. A storage tank is usually built into the system so that distilled water reserves can be stored away for use on demand rather than waiting for the system to produce more. Automatic distillers typically have a spigot for dispensing distilled water to be put away in a glass container or stored in the fridge.

Whole-House Distillers

Whole-house distillers for big families can be installed in a basement or garage and directed to various parts of the house where distilled water is needed. Distilled water can be directed to various appliances such as a fridge or icemaker when connected to the home's water system.

Some whole-house distillers have an automatic drain feature, which reduces the need for regular maintenance.

Commercial Distillers

Commercial distillers are much larger and more complex. They have the capacity to produce from 75 to millions of gallons of distilled water per day. To accommodate the large capacity, they contain multiple boiling chambers, allowing more water to be distilled at a time.

What is Distilled Water?

plastic water distiller

Distilled water is a type of purified water obtained through the process of distillation. Distillation removes impurities, including minerals and chemicals, and microorganisms, from water, so distilled water is free from impurities and dissolved solids.

Distillation relies on evaporation to purify water; it happens naturally as part of the earth's hydrologic cycle and can also be simulated within an enclosed system.

Because distilled water is absolutely free of minerals and contaminants, it serves a multitude of purposes. Humans use distilled water domestically for drinking, watering plants, filling humidifiers, steam irons, and fish tanks, to name a few.

Distilled water is also used commercially in automobile cooling systems, model steam engine boilers, modern engines, and to increase the density of air for airplane jet takeoff.

The pH of distilled water immediately after distillation is neutral at seven as it is pure. However, it absorbs carbon dioxide from the atmosphere and becomes slightly acidic with a pH value of 5.8. If considering distilled water for drinking, use a water distiller with a carbon filter, as this will reduce acidity.

How does distillation compare to other purification methods?

While filtration is effective at blocking parasites and bacteria, water filter pores often aren't small enough to block viruses.

While chlorination will kill both bacteria and viruses, some parasites have a protective shell making them resistant to chlorine.

While boiling will kill any living microorganism in the water, it won't remove any small particles or sediment.

Distillation will absolutely kill any living microorganism in the water and leave behind any debris, sediment, and heavy metals – leaving you with pure water.

How Does Distillation Work?

ocean rain / pxhere

Distillation is one of the oldest ways to filter water and is still used today.  It effectively removes contaminants from water, including bacteria, inorganic, and many organic compounds. Distillation separates a liquid from other substances with variations in boiling points. Distilling water involves boiling the water and then condensing the steam to form pure distilled water.

Distillation is actually the earth's natural way of purifying water on the earth's surface. Through the hydrologic cycle, water is evaporated from oceans and lakes by the heat from the sun. As the steam rises, water is condensed in the clouds, and when enough condensation has collected, water descends in the form of rain. Rain is, in fact, distilled water.

Water distillers emulate the earth's distillation process but on a much smaller scale.


In order to start the evaporation process, water needs to be heated. As the liquid water molecules absorb heat, they begin to move more quickly, giving them the energy to break the bonds connecting them together. When the molecules gain sufficient energy, they escape the surface of the liquid in the form of water vapor. Because the impurities, such as inorganic compounds and large non-volatile organic molecules, have higher boiling points than water, they do not evaporate with the water molecules. As water evaporates into steam, these impurities are left behind unchanged.


Condensation occurs when the evaporated water molecules – in the form of gas – begin to cool down and assume liquid form again. As the gas molecules lose heat, they lose energy and slow down, moving closer to the other gas molecules. The gas molecules eventually collect together to form liquid once again, minus the impurities. This "distilled" water is collected in a separate container, leaving the contaminants in its original container.

Distillation replicates the earth's hydrologic cycle. It begins with the evaporation of water from surfaces such as surfaces of the ocean, rivers, and lakes. The evaporated water forms water vapor which rises and then condenses in the atmosphere to form clouds. The process of precipitation occurs after condensation, which returns the purified water to the Earth’s surface in the form of rain and snow. So rain is essentially distilled water.

Difference Between Distilled Water and Some Other Types of Water

plastic water bottle H20

Distilled Water Vs. Filtered Water

Filtered water has gone through carbon filtration to block or chemically remove contaminants physically. Water filters block impurities with a barrier, and depending on the micron size of the barrier, some small impurities, such as viruses, may still go through. Filtered water is highly efficient at blocking larger contaminants such as sediment, bacteria, and parasites but inefficient at blocking smaller ones such as viruses and dissolved chemicals. Distilled water, on the other hand, leaves all contaminants behind. Read our article on portable water filters for survival and outdoors.

Distilled Water Vs. Purified Water

Purified water can be any water that contains less than 10 PPM contaminants. It is usually the result of a multi-stage purification process, like reverse osmosis, UV purification, or chlorination. These highly effective filtration processes can remove up to 99.99% of the contaminant in the water, resulting in purified water. As distilled water typically contains about 1 PPM of contaminants, it is, in fact, a type of purified water. However, the general difference between distilled water and water referred to as ‘purified’ is the mineral content. While they both have low levels of contaminants, purified water contains more minerals than distilled water.

Distilled Water Vs. Spring Water

Spring water refers to water collected directly from an uncontaminated underground spring where it rises to the surface. It is rich in minerals and considered to be great for hydration, and it provides other health benefits. Spring water is usually processed and filtered to remove debris and kill bacteria, but most of the mineral content, such as calcium and magnesium, is left in the water, while distilled water has negligible mineral content. Consequently, spring water has a fresher taste in comparison to distilled water.

Microbes are removed from filtered water, but not minerals. Spring water passes through a variety of natural filters, including rocks, and it contains high amounts of minerals. Harmful microbes, as well as harmless and beneficial minerals such as calcium and magnesium, are removed from distilled water.

Distilled Water Vs Reverse Osmosis Water

The water produced by reverse osmosis is as beneficial as distilled water, but the process in achieving purity is different. Reverse osmosis uses a semi-permeable membrane with pore small enough for only the H20 molecule to pass through. Whereas distillation achieves this through evaporation and condensation with a powerful heat source. Ultimately, reverse osmosis systems tend to be more costly and require more replacement parts than water distillers.

Distilled Water Vs Water Softener

The purpose of a water softener is to remove the minerals that contribute to a water’s hardness and nothing else, which means they focus primarily on removing magnesium and calcium. Water distillers remove much more than just magnesium and calcium.

Clarifying Some Misconceptions About Distilled Water

glass of water

  • Will Distilled Water Leach Minerals From My Body? - The truth is that distilled water does attach to minerals as it comes into contact with them. That is exactly how spring water enriches itself with minerals as rain flows downstream. So yes, distilled water can leech a small amount of minerals from your body along with other impurities in your digestive tract. But the amount of minerals that do get leached isn't enough to be of concern if you're consuming regular nutrients. We receive more than enough nutrients from a balanced meal than should be of concern. As humans, we receive our minerals and nutrients primarily from food, not from water. So if you're eating regular meals, drinking distilled water won't harm you. However, if fasting, take a break from distilled water during the fast and resume once the fast is done.
  • Cooking with distilled water removes minerals from the meal? - Whether you cook with normal water or with distilled water, your meal’s nutritional value will be the same.
  • Drinking distilled water will weaken your teeth? - Regardless of the amount of distilled water you drink, it will not drain the fluoride in your teeth. Yes, it will remove fluoride from the water, but toothpaste generally contains enough fluoride to keep your teeth healthy.
  • Distillation is an expensive process? - Distilled water is cheaper than buying bottled water. Although distillation requires electricity, the amount of electricity used to distill water is insignificant – a gallon of water will only need 30 – 40 pennies worth of electricity.

What Medical Professionals Say About Distilled Water

  • “Distilled water is safe to drink and should have no adverse effects on your health.  Distillation merely removes most of the dissolved materials, which are found in all natural waters.” —Raymond H. Bishop, Jr. M.D. Major General, Commander – Medical Corps. Department of the Army, U.S. Army Health Services Command
    • “I knew that distilled water was pure. I thought that if I drank plenty of it, I could get rid of some of the salts that were covering my sciatic nerves. I tried drinking it and it worked like a charm. I have kept up my drinking of distilled water and I attribute my almost perfect health largely to it.”
      —Dr. Alexander Graham Bell
    • “Even tap water invariably contains a variety of poisons such as chlorine, chloramine, asbestos, pesticides, fluoride, copper, mercury, and lead. The best way to remove all these contaminants is by distilling.” —David C. Kennedy, D.D.S. ‘How To Save Your Teeth: Toxic-Free Preventative Dentistry’
    • “Distilled water is the greatest solvent on earth. (It is) the only water that can be taken into the body without damage to the tissues. What we as scientists and the public have never realized is that minerals collected in the body from water are all inorganic minerals, which cannot be assimilated (digested) by the body. The only minerals that the body can utilize are the organic minerals (from fruits and vegetables). All other types of minerals are foreign substances to the body and must be disposed of or eliminated. Today, many progressive doctors prescribe distilled water to their patients. All kidney machines operate on distilled water.”  – Allen E. Banik, M.D. Author, “The Choice is Clear”

    How to Use and Maintain Home Distillers

    water distiller

    When the water evaporates, some contaminants remain behind in the steam chamber. These contaminants will build over time, eventually affecting the faucet and the boiling chamber. To avoid the buildup, you will have to clean your water distiller periodically. Here are some steps to ensure your water distiller is in great working condition.

    Clean the Lid

    If you have a removable lid, remove and soak it in a sink full of water. Mix the water with 1/4 cup of vinegar or lime/lemon juice before soaking the lid. If the lid cannot be removed, mix 1/4 cup of vinegar or lime/lemon juice in a bowl, then clean the lid using the solution with a clean cloth or a scrub brush.

    After cleaning the lid, rinse the steamer to remove all traces of the solution, then dry with a cloth.

    This should be done when cleaning the boiling chamber.

    Clean the Boiling Chamber

    The boiling chamber should be rinsed out after each use and cleaned at least once a month.

    You will need a solution of 1 part water and 1 part vinegar to clean the boiling chamber. Make enough solution to fill the chamber above the line of mineral deposits by at least 2 inches. Scrub with a soft sponge until the mineral deposits are gone.

    Remember to avoid using commercial detergents to clean the water steamer, as traces of the detergent may remain after you rinse it. Your water can absorb these traces of detergent and can possibly lead to accidental intoxication.

    Replace parts as needed

    The part that will need to be replaced most frequently is the carbon filter, which is done every three months or whenever you notice a change in taste. Carbon filter replacements are inexpensive and are worth having extra on hand.

    Other parts, such as 0-rings and gaskets, will need to be replaced as needed due to normal wear and tear.


    Boiling tanks with manual drainage will need to be performed every 2-3 weeks or whenever it gets full. Units with automatic drainage can remain out of sight and out of mind if properly connected to a drain pipe.

    Steam sterilization

    Some automatic units have a steam sterilization feature that sterilizes the entire unit, preventing the growth of microorganisms. This should be performed at least once a year.

    Water Distiller FAQs

    How long can distilled water be stored for?

    Because of the absence of ions and minerals within the water itself, the shelf life of distilled water is dependent on the type of container it is stored in. While food-grade polyethylene plastic is safe for long-term storage in water, it does have the potential to leech minerals from the environment if not stored correctly, especially when placed directly on concrete. Sealed glass containers are best for keeping distilled water undisturbed and pure. A well-sealed, undisturbed container of distilled water can last several months or even years.

    Why does distilled water taste different?

    Natural spring water has a distinct “sweetness” to its taste due to the abundance of minerals within it. The absence of these minerals can leave water tasting slightly flat or bland, as is the case with distilled water. The distillation process can also remove some oxygen from the water, leaving it flat, but stirring or shaking the water can reintroduce oxygen to improve the taste. Adding mineral salts can improve the taste and raise the pH level.

    What is the purpose of a post-carbon filter?

    While distillation removes contaminants during the evaporation process, VOCs (Volatile Organic Contaminants), chemicals with high vapor pressure, may carry over through the evaporation and condensation process. The post-carbon filter ensures that any remaining VOCs are caught at the final stage. The carbon filter also acts to enhance the water flavor. Carbon filters used every day should be changed once a month.

    Why is distilled water acidic?

    Distilled water can be slightly acidic due to the carbon dioxide from the atmosphere, which is dissolved into the water. The carbon acid tips the water slightly to the acidic side of the pH scale. The level of acidity is very minute and is easily handled by the digestive system.


    Having the means to effectively distill water at home will guarantee access to pure, clean water whenever you need it. As a reminder, distilled water is free of all minerals and should be remineralized if intended to drink for long term. Water distillers should be cleaned regularly for maximum performance.
