While filters can help reduce the amount of contaminants in your drinking water, the only way to ensure pure H2O is through a water distiller. Much like the earth’s natural water cycle, these appliances heat up water until it turns into steam, which is then condensed back into pure H2O. This process effectively removes all impurities from the water, including not only lethal viruses and bacteria but also low levels of chemicals and heavy metals that can impact long-term health.

Water distillers come in various designs, sizes, and price points, so the best one will vary from household to household. For example, some distillers heat up faster than others, while others may feature more or less water capacity. High-end water distillers often offer additional features, such as programmable time settings and carafes made of high-quality glass rather than plastic.

Below, we’ve rounded up some of the best water distillers on the market, vetted according to standards such as quality, ease of use, and price. Whether you’re looking for the best water distillation systemfor personal hydration or for the whole household, one of these may be best suited to fit your needs.

What to Consider When Choosing the Best Water Distiller

Most water distillers share a similar design, consisting of a carafe or pitcher that catches the water and a heating element that steams and dispenses it. But many factors of this design can vary, from size and capacity to durability and efficiency.

Type

Unlike some of the top water filters, which can range in type from pitcher to plumb-in models, the best water distillers share a more similar design. Most models we reviewed consist of two main parts: the boiling chamber, which heats and cools the water, and the carafe or pitcher, which collects it for drinking. Some distillers also incorporate internal filters to further clean the water of any contaminants before or after the distillation process.

Alternatively, some distillers may feature a more rudimentary design, consisting of a copper coil and large pot that can be filled with water and heated over the stove. These kits are sometimes marketed for emergency situations or for alcohol distillation, but they can also be used to purify water at home.

Capacity and Speed

For everyday household users, among the most important features of a water distiller are capacity and speed. While water distillers may operate more slowly than regular water filters, which do not have to heat and cool the water, it’s beneficial for them to work quickly and efficiently. The right water distiller should also be able to hold enough water to hydrate the entire household, whether it consists of just one person or a whole family.

At the very least, a good water distiller is often able to purify a single person’s daily recommended hydration requirements—around 2 to 3 liters—in just a few hours. Some are faster than others, making them a more convenient option for users who drink tap water regularly. There also are water distillers that are able to hold and purify large quantities, making them more suitable for multimember households.

Materials

When it comes to picking the right water distiller, material construction is particularly important. Water distillers are designed to produce pure, contaminant-free H2O, and the material construction and quality of the appliance can ultimately impact that very purity. For example, it’s important that the distiller’s boiler chamber and associated parts be made of stainless steel since that will help prevent them from oxidizing or corroding over time.

It’s also worth considering the material of the carafe that collects and stores the water. Some plastics contain BPAs and other chemicals that can leach into the water after it’s clean, so finding a distiller that is free of those toxins is important. In general, glass carafes are more sanitary than plastic ones, not only because they’re free of toxic chemicals but also because they are easier to clean and keep clean.

Beyond cleanliness, the material construction of a distiller will also affect its durability. Glass may be cleaner than plastic, but the latter tends to be more durable, which may be an important consideration in accident-prone households.

Filtration

Water distillers work through a process of distillation, during which the water is boiled to release steam, and the steam is cooled and condensed into pure H2O. Because the vast majority of chemicals and contaminants are left behind when the water evaporates, this ensures purer water than regular filtration, which invariably allows some impurities to seep through.

Still, many water distillers incorporate filters for added benefit. Some contaminants, such as volatile organic compounds (VOCs), can exist in a gaseous state, allowing them to survive the distillation process. To capture those toxins, many distillers come with an activated-carbon post filter through which the purified water runs before being dispensed into the carafe.

Additionally, while distillation may effectively remove toxins from tap water, the process can also strip it of certain minerals that actually contribute to our health. To that end, some distillers also incorporate remineralization filters, which reintroduce certain healthy minerals back into the water after it’s been purified.

Energy Consumption

Depending on their size, water distillers can vary in terms of energy consumption. Water distillers designed for use in the U.S. will run off of a standard 110 or 120 volts, the same as most household appliances. In terms of energy consumption, a medium-size water distiller consumes around the same amount as a small drip coffee maker—somewhere between 500 and 800 watts.

To improve their energy efficiency, many water distillers include automatic shut-off features that keep them from sucking up energy when not actively distilling water.

Certification 

While there is no universal certification standard for water distillers, the most reputable models will often carry approval from Underwriters Laboratories (UL), a nonprofit organization that vets the safety and quality of small appliances and products in the United States. A UL certification ensures that a water distiller has been tested and conforms to certain industry-wide standards of safety and quality.

Our Top Picks

Taking the above features into consideration, we selected some of the best water distillers on the market for specific situations and needs. Our top picks include models with a large capacity, a compact design, and high value for money for those on a budget.

Our Verdict

For an efficient, easy-to-use water distiller for casual home use, our favorite choice is the Megahome water distiller. Alternatively, shoppers looking for a reliable way to purify their tap water without spending a ton of money may want to consider the affordable Mophorn water distiller.

How We Chose the Best Water Distillers

To find the best water distillers out there, we spent hours researching the most trusted brands and models on the market according to both user and expert reviews. We initially looked at more than a dozen different options, vetting them based on features like material quality, durability, efficiency, and ease of use. We took into special consideration each model’s capacity and distillation speed, as these are two of the most important features for casual home users.

Because distillation is a useful way of purifying water in emergency and outdoor situations, we also differentiated between and included both electric and nonelectric models.

The Advantages of Owning a Water Distiller

Although most tap water in America is deemed safe to drink, safe doesn’t mean it’s healthy. The U.S. Environmental Protection Agency sets legal limits on more than 90 contaminants found in tap water, from viruses and bacteria to chemicals like fluoride and lead. But some trace amounts of these impurities can still make their way into our drinking water and can have negative effects on our long-term health.

A water distiller is one of the most effective ways that shoppers can ensure they’re drinking the purest water possible. Unlike a faucet water filter or even reverse osmosis, a distiller separates the water from any harmful chemicals through evaporation and condensation, resulting in purer H2O. By stripping these impurities, a distiller can produce water that is not only healthier for the body but that also tastes and smells better.

Distilled water isn’t just better for the body, either—it’s also easier on the wallet. Though distillers require an up-front investment, they can save users from having to buy distilled bottled water, making them a more economical choice in the long run. Accounting for energy costs, many distillers can produce pure water at less than 25 cents per gallon.

  • Drinking distilled water is healthier than plain tap.
  • Water distillers produce purer H2O than filters or reverse osmosis.
  • Distilling water is cheaper than buying it.

Tips for Cleaning a Water Distiller

To keep a distiller operating for a long time, it’s important to clean and maintain the appliance regularly in between uses. This is especially true for the distiller’s boiling chamber, which can become covered in heavy-metal scale and other impurities left behind during the distillation process. If left uncleaned, this scale can corrode the inside of the chamber, ruining the appliance.

Cleaning methods may vary from model to model, but most water distillers can be cleaned with a simple rinse and scrub. If there is excess limescale buildup in the chamber, the unit may need to be soaked for a few hours in a cleaning solution. Many of the distillers in this list come with their own cleaning solutions to help break down residues and buildup inside the chamber. It’s important to clean a water distiller regularly, preferably after every use.

When in doubt, consult the manufacturer’s instructions for tips on cleaning the distiller.

  • For best results, water distillers should be cleaned often—ideally between uses.
  • Pay special attention to the buildup of heavy-metal scale in the boiling chamber, which could lead to corrosion and rust.
  • Some distillers may include special cleaning products to break down excess scale.
  • Consult the manufacturer’s instructions for specific tips on cleaning.
