This model comes with a one-year warranty that covers all parts and labor – additional two- and three-year warranties are also available for purchase. H2o Labs offers a lifetime, full trade-in value guarantee, so if you decide to upgrade to a different model, the company will take yours back in trade. It’s made from high-quality materials – stainless steel and food-grade, BPA-free plastic.

Consumers love that this unit is both easy to use and to clean, though some have reported the need to run the water through multiple distilling cycles before it tasted truly “pure.” However, most reviewers found the unit highly effective from first use and appreciated the unique release of the finished water through a nozzle leading from the water reservoir. With this exclusive design, the water won’t touch any metal or plastic as it leaves the container, preventing any chance of recontamination.

3. Mini-Classic Stainless Steel Water Distiller

View Price

 

This small, stainless steel unit sits easily on your kitchen counter and distills up to three liters of water per cycle, which takes roughly three and a half hours. This is a compact unit that can certainly fit in most kitchens, and is even a good option for use in a camper or RV. With its smaller capacity, it might be best for a single-person residence. Weighing in at 24 pounds, though, it’s on the heavy side, so keep that in mind in terms of portability.

The Mini-Classic CT is made of top-quality stainless steel; it is air-cooled and includes an automatic shutoff function when a distillation cycle is complete. In addition, this model includes the capability to shut off if the unit begins to overheat. The boiling chamber is removable for easy filling, plus cleaning, and this model features continued self-sterilization.

This water distiller also includes an activated carbon post filter, which helps improve taste and ensure that any gaseous carryover is filtered out. Each Mini-Classic CT includes a one-gallon glass container with handle and pour-through lid, which fits nicely within the refrigerator; you also can order additional jars.

Users particularly liked the fact that this unit is fairly quiet while it runs; it produces a bit of white noise that some appreciate, but it doesn’t produce enough sound to interfere with normal home activities. And perhaps its greatest advantage is that it is ready to use right out of the box – there’s no need for any type of assembly or installation, so it’s especially good for first-time water distillers. This unit is on the slower side, though, in terms of production– the three-and-a-half-hour filtration time was a challenge for some.

4. Mophorn Stainless Steel Water Distiller 

View Price

 

This water distiller will allow you to distill up to six gallons of water per day and includes a 1.1 gallon BPA-free plastic container. This model is easy to use and comes with a budget-friendly price tag – it features a one-button start, automatic shut-off and built-in thermometer to prevent overheating, as it automatically shuts off when the temperature reaches 320 degrees Farenheit. It also works a little faster than some others, but also uses more power. This is a relatively quiet unit, and it’s designed with large openings so that it’s easy to clean and easy to access for filling the boiling chamber.

This is a nice, budget-friendly unit that you may want to try if you’re venturing into distilling water for the first time. With a relatively fast water distillation rate, this unit can produce roughly a quarter of a gallon of water in right around an hour. At this rate, it should be able to distill six gallons of water per day. The CO-Z 4’s internal steam chamber is made from stainless steel, but its accompanying one-gallon water container is plastic, which emerged as a con for some users. The plastic used is food-grade and BPA-free.

Like many units, the CO-Z 4 includes a few safety measures to prevent accidents – for example, it comes with surge protection and also features a thermostat that prevents the distiller from overheating during the distillation process. In addition, the machine will shut off if the water level gets too low or if the temperature rises above 300 degrees Farenheit. Overall, it’s a good user experience – both easy to use and easy to clean.

Weighing in at 9.6 pounds, the CO-Z 4 is a little bulkier than some other models, but still relatively portable for travel use. Users like the speed of this particular model, though the chief downside they report is the plastic water container used for collecting the finished water. Many people who choose water distillers have strong environmental concerns, so the plastic reservoir could be considered a disadvantage. In addition, some users report that the machine puts out a great deal of heat.

6. ROVSUN Water Distiller with Stainless Steel Interior

This is a nice, mid-line model that offers some of the most desirable water distiller features, like a glass container and reasonably fast distillation speed, without blowing up your budget. The 750W, high-power model allows you to distill up to six gallons of water per day and, like many of the other machines we reviewed, includes a built-in thermostat that helps keep the unit from overheating and features automatic shutoff. The ROVSUN distiller offers easy assembly and cleanup and runs quietly in the background of your home.

This version is made from high-quality materials: it offers a white, baked-enamel body, and the inner tank and condensing coil are made from 100 percent stainless steel. In addition, the water container that comes with the unit is made from food-grade, BPA-free plastic and includes a handle for ease of use.

The ROVSUN design offers several options for where this unit can live within your home; it’s also nicely portable, so you can take it on vacation, inside an RV, etc. Each unit comes with a one-year seller’s guarantee, and the company supplies special chamber-cleaning powder in order to help descale your machine when necessary, along with charcoal sachets for filtering.

Users particularly liked the value of this model and also reported that assembly, use and cleaning were all quick and simple and that customer service was prompt and supportive. There are some reports of an oily residue inside the distiller, along with a poorly written instruction manual, as areas of struggle. As with some other models, the plastic container can be an issue for some users.

7. H2o Labs Water Distiller with Easy-Fill Reservoir

View Price

 

With a modern design and advanced functionality, this water distiller by H20 Labs is touted as the most convenient countertop water distiller. With a daily capacity of four gallons – one gallon in approximately five hours – it’s a little on the slower side, but makes up for that with convenience and portability.

It is simple to operate and energy efficient, along with being relatively lightweight for portability. This model comes with a lift-out, easy-fill water reservoir that features a continuous water-feed valve, and it also features automatic shutoff at the end of a distillation cycle. While it isn’t as sturdy as some of the stainless steel options we’ve reviewed, it does consistently provide good quality distilled water for a reasonable price.

All plastics used in this model are food-grade and BPA-free. This particular unit is lightweight, which makes it an ideal option for seniors or others who may have challenges lifting heavier models. In addition, it’s ready to use right out of the box – no assembly or installation required. One unique feature is the machine’s stick-resistant boiling tray, which helps cut down on scale buildup and make the unit easier to clean. The machine can effectively run for six distillation cycles between cleaning.

There’ve been a numerous reports that the unit is easy to set up and use, and that the customer service experience is largely positive. Some reviewers report a struggle with the lack of a spigot on the water container and many, at the end of the day, would still prefer a stainless steel version over the plastic of this model.

How Water Distillers Work

At its heart, water distillation is about strategically applying heat – because water boils at a lower temperature than most of the minerals and contaminants it might contain, like heavy metals, bacteria, salt, calcium and phosphorus, water heated to its boiling point transforms into water vapor, leaving all other molecules behind.

The separated water vapor can then be routed through a condensing coil into a reservoir where it can safely reconstitute as liquid as it cools, without the other substances it left behind.

The distillation process is as old as the earth itself; it’s part of the basic water cycle. Water on the surface of the earth is routinely heated to its evaporation point by the sun, and as a result, it becomes water vapor, which forms clouds. Once atmospheric temperatures drop to an appropriate point, that water vapor cools, returns to liquid form and falls back to the earth as rain. Once water reaches the surface of the earth once again, the process starts all over.

Humans have been distilling water since at least as far back as 200 CD – and likely even farther. Historically, societies have used water distillation to transform salty seawater into drinkable freshwater. In fact, some sources indicate that ancient Greek sailors converted seawater to drinkable water by hanging sponges over buckets of boiling seawater, then wringing the freshwater out of the sponges to drink.

Today’s most common water distillers are small enough to fit on a kitchen counter and function as basic, single-stage distillers. In addition, most water distillers are extremely easy to use; they don’t involve complicated installation and are basically ready to use once they’re plugged in.

The basic process goes as follows:

1. Tap water is placed into the boiling chamber of a water distiller.
2. A heating element applies heat to the boiling chamber, which causes the water to boil.
3. Once boiling, the water converts from liquid form to water vapor.
4. The water vapor is allowed to rise from the boiling chamber and exit through a vent.
5. Minerals, contaminants, salt, etc., because they have higher boiling points, are left behind as solid elements in the boiling chamber.
6. The water vapor then passes into a condenser, where it can be cooled by a fan or by other cool, distilled water.
7. As the vapor cools, drops of water reconstitute. Depending on the unit you’re using, you may also have a carbon filter that the water can pass through in order to remove any residual gases.
8. The distilled water can then be collected in a separate container or reservoir.

 

Advantages of a Water Distiller

Distilled water is considered the purest, safest type of potable (drinking) water. Distillation is especially helpful for residential areas that don’t receive municipally treated water – particularly where well water is concerned, users often face high concentrations of metals and contaminants. Distilled water has been highly purified and is about 99 percent free from harmful substances like debris and bacteria, which provides many benefits. When drinking distilled water, your body no longer is forced to process unusable inorganic materials, leaving it free to function more efficiently. This also can lead to higher vitamin absorption, and some studies also have indicated that drinking distilled water is good for your skin – because it is free of any harmful dissolved substances, it can help in blocking of microscopic pores on the surface of your skin.

In general, distillation effectively produces highly treated drinking water, reducing measurable levels of metals, sediment and biological contaminants since they’re unable to travel with the water as it converts to water vapor. In addition, a distillation system that also includes activated carbon filtration can address other contaminants that lead to unpleasant tastes, odors or colors in your water – elements like magnesium or chlorine, for example.

Other advantages associated with distilled water include increased energy, heightened mental performance, weight loss, improved skin appearance, a reduction in stress/anxiety/depression, relief from dizzy spells and headaches, improvement in allergy, asthma and arthritis symptoms, improved digestion, protection of joints, enhancement of immune function, and more.

You can rest assured knowing the following about the distilled water your chosen unit will help you produce:

• It’s free of pathogens – most bacteria and viruses are killed during the boiling process, and any that aren’t are left behind when liquid water converts to water vapor.
• It’s free of carcinogens – distillation can remove most chemicals, and any volatile organic compounds that might boil at temperatures lower than water are removed through the filtration process.
• It helps your body detox – by drinking additive- and mineral-free water, you help your body flush out minerals, harmful chemicals and other toxins that otherwise can build up in cells and particularly around joints.
• It is fresh – if you buy distilled water by the gallon, you’re getting a product that may have been sitting inside a plastic bottle on a store shelf for weeks or months at a time. And because distilled water is so pure, it can easily soak in the taste and odor of the plastic containers in which it’s stored. In addition, store-bought distilled water usually is produced in large batches by industrial distillers, which may affect its freshness and purity. But – if you’re using your home unit to distill your drinking water in real time, the taste and odor will be fresh and clear, plus providing you with the most superior health benefits associated with distilled water.
• Distilled water is absolutely pure, with no unnecessary contaminants – Even though the water that comes through your tap may have been municipally treated, it’s not uncommon for tap water to pick up sediment as it travels from a treatment plant to your home; in addition, tap water often contains a chlorine residual. The distillation process can remove all of these extra elements from your water. Distilled water will contain no iron, salt, fluoride or any other unnecessary mineral or compound.

 

Distilled Water vs Purified Water vs Spring Water

It’s easy to get confused about the differences among distilled water, purified water and spring water. Let’s try to cut down on the confusion.

As we’ve established, distilled water is pure, fresh water with all chemicals, trace elements, sediment, etc., removed through a process that closely mimics the natural hydrological cycle. It is one type of purified water, but not the only type. And distilled water can come from any source; it’s the distillation process that defines it.

Water labeled as “purified” is also defined by its treatment – but it’s a broad, umbrella term that indicates that this water may have been treated in a variety of ways. For example, distilled water is a type of purified water – the distillation process has purified it by removing contaminants, metals, sediment, etc. However, all purified water isn’t distilled water. “Purified” simply means that the water has undergone an extra purification step – that may be distillation, reverse osmosis or deionization – and purified water can come from any source.

On the other hand, water touted as “spring water,” is defined by its source rather than the process by which it’s treated; in order to be labeled as “spring water,” the source should be an underground spring that is theoretically protected from contaminants. However, spring water often includes a wide range of water purity levels and may contain many of the same extraneous elements found in tap or well water. And some studies have indicated that many spring water brands are actually tap water that’s been bottled and marketed to consumers. Be careful as well about any spring water labeled as “100 percent pure” – the claim of purity actually applies to the source and not necessarily to the water itself. In effect, 100 percent of the bottle’s contents should have come from an underground aquifer source rather than a surface water source, which is where most municipal water supplies come from.

 

Water Distiller Maintenance and Cleaning

Once you’ve chosen your water distiller, it’s relatively easy to clean and maintain. Keep in mind that all the contaminants left behind in the boiling chamber can have an adverse effect on your distiller over time. It’s a good practice to periodically clean your unit in order to dissolve any hard-water scales that might accumulate and to remove any sediment that it has collected through the distillation process. Speaking of hard water, if it’s a problem through out your home, you might want to look into purchasing a water softener system. In addition, you’ll lower the chances that your distiller suffers from mold growth in the long term. If you’re also using a carbon filter, you should establish a schedule for replacing it according to manufacturer recommendations.

Most units are designed to clean quickly and easily – you can mix about ¼ cup of white vinegar with ¼ cup of lime or lemon juice to make a powerful cleanser. First, turn off the power to your unit. Then, simply use either a scrub brush or clean cloth to clean the lid of your unit with the solution you’ve made. If the lid is removable, you can also soak it in warm water with a bit of vinegar and lime/lemon juice added. Then just rinse and dry, and you’re ready to use your distiller again.

To clean the boiling chamber, mix ½ cup of warm water and ½ cup of either lemon juice or vinegar and fill the chamber, making sure the water level is above any mineral deposits by a couple of inches. Let soak overnight, then rinse thoroughly and dry.

One of the most important points to remember is that you should use natural elements like vinegar and lemon to clean your water distiller instead of commercial detergents. These detergents can easily leave behind traces of chemicals within the boiling chamber, which then could make their way into your drinking water, defeating the purpose of distillation.

 

Best Water Distiller Buyer’s Guide

Home water distillers are easy to find, either online or at brick-and-mortar retailers focused on home goods. However, before deciding on the water distiller that’s best for your home, there are several factors you should consider.

First, consider how you’ll want to use your distiller on a day-to-day basis. How much water do you need to meet your family’s needs? If you simply want to distill water for your family to drink, a small, countertop version – like any of those reviewed here – is likely to be sufficient. A good recommendation is to plan for two gallons per person, per day, within your household for drinking water. However, if you’re looking to distill all the water that flows into your home – not just your drinking water – you’ll need to consider a larger commercial unit that is designed to process 1,000 gallons or more per day. Many people also enjoy cooking with distilled water, watering their plants with it, giving it to their pets to drink or using it for their aquariums. Think carefully about all the ways your family can benefit from using a distiller and plan accordingly.

Second, consider the costs and the return on your investment. For example, if you’re currently spending a large amount of money on purchasing bottled water, investing in a home water distiller can reduce your water spending over the long term as you replace bottled water with water you’ve distilled.

Some estimates show that a gallon of water distilled within your home averages around 25 cents, compared to an average cost of around a dollar for one individual bottle of water. While the initial cost of a water distiller can be quite the investment, you will be able to quickly recoup those costs with bottled water savings. And budget versions like the ROVSUN Countertop Water Distiller, the CO-Z 4 or the Mophorn Pure Water Distiller are especially economical.

You might also consider the speed at which your distiller will deliver pure, fresh water. Larger distillers are able to distill water faster simply because their heating elements are a higher wattage – the increased speed lets you enjoy your distilled water with a shorter waiting time. For example, the CO- 4 and the Mophorn Pure Water Distiller have been favorably reviewed in terms of distillation speed.

Another consideration is the energy required to power your water distiller. A good estimate to count on is 3KWH of energy per gallon of distilled water produced. So if you know how much your family is likely to distill per day, month, etc., that can help you calculate the effects on your power bill.

Think as well about where you’d like your water distiller to live. Small, countertop versions can easily fit within your kitchen space, but larger, more powerful units may need to be installed in a garage, basement, etc., with remote water lines to the kitchen and other areas throughout your home. Any of the models we’ve reviewed here can fit well within your kitchen décor without taking up too much space. For example, the Megahome model is particularly stylish, while the Pure Water Mini-Classic is especially compact.

The good news is that with so many options available, you’re sure to find something that meets your needs for production level, energy use, size and budget. In fact, if the countertop style of distiller is what you’ve set your sights on, consider learning about the best countertop water filters.
