7 Best Water Distillers in 2019 – Reviews and Buying Guide

Best Water Distiller

There are many ways to assure safe drinking water for you and your family but very few of them are as effective as distillation. With a water distiller, you produce drinking water that has lost over 99.9% of its contaminants.

Distillation is not new, it's a tried and tested system that has been in use for ages. A distiller heats up water until it evaporates. This vapor is then passed through a series of cooling tubes to produce distilled water. The impurities don't evaporate and the microorganisms get killed by the heat.

Distilled water comes without the minerals, bacteria or viruses that are often found in other sources of water. With home-made distilled water, you can guarantee a 100% safe drinking water source for your family.

Fortunately, many companies have come out with compact distillers, designed to serve the average home and this water distillers review will show you how to make the right choice.

You get a list of the top distillers in the market and a buying guide that shows you exactly how to choose the right offer.

1. Megahome MH943TWS Charcoal-Filter Countertop Water Distiller

Editor's Rating: 4.6 out of 5 stars (4.6 / 5)

Megahome MH943TWS Charcoal-Filter Countertop Water Distiller
  • Distilling Capacity: 1 gallon / 5 hours
  • Material: Glass
  • Dimensions: 9 x 9 x 13 inches

The Megahome MH943TWS is one of the best water distillers for home use that you can find. It features a sturdy and durable construction, including 304 stainless steel and glass parts.

Megahome guarantees you that your water will not touch plastic once inside the distiller and this means that there's no chance of getting chemicals leached into the distilled water.

This countertop distiller is also UL listed and approved, guaranteeing you that it meets all the necessary safety standards. Megahome then backs it with a 1-year warranty, including a friendly and quality support.

It distills 1 gallon of water in about 5.5 hours, which is not the fastest speed. It does, however, offer an activated charcoal filtering system to further get rid of any volatile organic compounds in the water.

You also don't need to stick around while it's working, because it will automatically shut-off once it's done. Just fill the tank with water, place the 1-gallon glass collector correctly, and turn on the system, that's it.


  • Features a stainless steel and glass interior
  • Distilled water gets collected in a glass container
  • Includes activated charcoal filter
  • Backed by a 1-year warranty


  • It's a bit slow at producing 1 gallon in 5.5 hours
  • The design is neither trendy nor beautiful

2. H2o Labs Top-Quality Water Distiller

Editor's Rating: 4.6 out of 5 stars (4.6 / 5)

H2o Labs Top-Quality Water Distiller
  • Distilling Capacity: 1 gallon
  • Material: Glass / stainless steel
  • Dimensions: 16.5 x 12 x 11.3 inches

This brand has consistently been rated the best overall water distiller in its class and you are about to see why. Its steam chamber, for example, is entirely made of stainless steel, and that's including the condensing coils.

It comes with an "easy lift" glass carafe, making sure that your distilled water does not touch plastic along the way. Then there is also a porcelain nozzle insert for the highest purity standards, letting you know why this countertop distiller is one of the best countertop water distillers in the world.

The distiller comes with a 565-watt heater and H2o argues that this is the ideal size for distilling a 1-gallon tank. The reason is that a larger heater might distill the water faster but you'll get more contaminants in the distilled water because the tank got boiled too rapidly.

It takes 4-5 hours to make a gallon and it can make up to 4 gallons a day. The only issue is that it has a rather high price tag but H2o Labs backs it up with a 1-year warranty.


  • The entire steam chamber is from stainless steel
  • Features a glass carafe
  • Includes activated charcoal filters for VOC removal
  • Makes up to 4 gallons per day


  • The price is on the high side
  • Some machines are faster at distilling water

3. Morphon 1-Gallon Countertop Water Distiller

Editor's Rating: 4.1 out of 5 stars (4.1 / 5)

Morphon 1-Gallon Countertop Water Distiller
  • Distilling Capacity: 1 gallon / 4 hours
  • Material: stainless steel & plastic
  • Dimensions: 15.3 x 9 x 9 inches

Top-rated water distillers don't have to cost a fortune and that's the message that Morphon is sending with this 1-gallon, countertop water distiller that's the cheapest offer in this review.

Unlike other top-rated brands that use stainless steel and glass exclusively, Mophorn uses stainless steel in the inner chamber and a BPA-free plastic carafe to catch the filtered water.

Another plus with this offer is that it comes with a 750-Watt heater and this makes it produce 1 gallon in as little as 4 hours, making it able to produce up to 6 gallons every day.

This offer also looks stylish and you can get it in different colors including red and gold, although there are slight price variations for choosing other colors.


  • Comes with a powerful 750-Watt motor
  • Delivers 1 gallon in 4 hours & up to 6 gallons per day
  • Made with stainless steel & BPA-free plastic
  • Offered at a low and attractive price

4. CNCShop Stainless Steel Water Distiller

Editor's Rating: 3.6 out of 5 stars (3.6 / 5)

CNCShop Stainless Steel Water Distiller
  • Distilling Capacity: 1 gallon / 4 hours
  • Material: Plastic & stainless steel
  • Dimensions: 20 x 9 x 4 inches

Here's another very affordable countertop water distiller, great for those who are on the search for the best distiller for the money. It comes in plain white plastic and features a plastic collection bottle, but that's not all.

You get a stainless steel interior and that includes everywhere that has to deal with heat and turning the water into steam. The water distiller itself will take up to 320 degrees Fahrenheit before switching off automatically.

Its heater burns 750 Watts of electricity to produce about 1 liter of distilled water every hour, which means or equals 1 gallon every four hours.

The package includes an instruction manual, a cleaning powder for the stainless steel chamber, a filter, and a discharge cap for the collection bottle, which is perfect for going into the fridge.


  • Powered by a 750-Watt powerful heater
  • Produces one gallon every 4 hours
  • Comes with an extra filter
  • One of the best budget water distillers you can find


  • It includes many plastic parts
  • Not very stylishly designed

5. ROVSUN 750-Watt Countertop Water Distiller

Editor's Rating: 4.5 out of 5 stars (4.5 / 5)

ROVSUN 750-Watt Countertop Water Distiller
  • Distilling Capacity: 1 gallon / 4 hours
  • Material: Stainless steel & glass
  • Dimensions: 9 x 9 x 15 inches

This ROVSUN water distiller features a modern and stylish design, which makes it a top choice for those who love stylishness. Its housing is stainless steel and the carafe is glass with a stainless steel cap.

At the bottom of the carafe is an anti-skid ring and the steel cap includes a stainless steel water inlet, which is not removable.

You get a 750-Watt heater, which is powerful enough to produce about a gallon of distilled water every 4 hours. It's also lightweight enough and easily portable.

The countertop distiller is also available with a champagne gold housing and ROVSUN backs it with a 1-year warranty. There are many accessories included in the package like three sachets of an activated charcoal filter and a cleaning powder for the boiling chamber.


  • Beautifully designed distiller
  • It's powered by a 750-Watt heater
  • Made of stainless steel and glass
  • Backed by a manufacturer's 1-year warranty
  • Comes with many accessories


  • It's not a cheap water distiller
  • The package only includes 3 filter sachets

6. Co-Z Countertop FDA-Approved Water Distiller

Editor's Rating: 3.6 out of 5 stars (3.6 / 5)

Co-Z Countertop FDA-Approved Water Distiller
  • Distilling Capacity: 1 gallon in 4 hours
  • Material: Plastic & stainless steel
  • Dimensions: 19 x 11 x 10 inches

If you don't mind the plastic housing, then you can gain a lot from this offer because it's well priced and features a powerful heater which helps it keep up an acceptable distilling capacity.

Although there's nothing special about its design, it's a reliable distiller that can produce about a gallon of water in 4 hours, plus it includes a high-temperature automatic shut-off system for your safety.

The steam chamber comes lined with 304 stainless steel anyway, but the last collector is from plastic, although it's a BPA-free and guaranteed food-grade plastic.

If you take care of this distiller and don't misuse it, then you'll definitely use it for decades to come because it's a well-built distiller water machine, in spite of its many plastic parts.


  • Comes with powerful 750-Watt heater
  • Produces 1 gallon of distilled water in 4 hours
  • Steam chamber is stainless steel
  • Backed by a 1-year warranty from C0-Z


  • It's made mostly of plastic

7. Mini Classic CT Pure Water Distiller

Editor's Rating: 3.9 out of 5 stars (3.9 / 5)

Mini Classic CT Pure Water Distiller
  • Distilling Capacity: 1 gallon / 4.5 hours
  • Material: Stainless steel and glass
  • Dimensions: 13.5 x 10 x 15 inches

The Mini Classic CT water distiller offers you in simple terms, the best countertop water distiller you can lay your hands on. This water distiller is in a class of its own, as you are about to find out.

It starts with the entirely stainless steel construction of the distiller, plus its glass container, which comes with a handle and a pour-through lid, perfect for the refrigerator as well.

The boiling tank is removable, so you can fill it with water easily. It takes about 3 liters of water and the distiller can process it in about 3.5 hours, and this includes passing the water through its charcoal filter.

One thing that's a bit tasteless about this distiller is its price, but if you want a quality and self-sterilizing water distiller that's as good as this one, then you'll agree with me that no price is too much for true value.


  • The powerful 800-Watt system delivers 1 gal in 4.5 hrs
  • The most powerful offer in this water distillers review.
  • Made entirely from stainless steel and glass
  • Includes charcoal filtering pads for maximum purity
  • Backed by a 15-year warranty


  • It's the costliest distiller in this review
  • The design is not visually appealing

How to Buy The Best Water Distillers

How to Buy The Best Water Distiller

Since there are different kinds of water distillers out there, there are few factors that you'll need to consider when making your choice because they'll help you to make the right choice.

#1. Your Water Needs

You need to consider your water needs first and what this means is that you need to know how much water you or your family consume per day. If you have no idea, then you may need to take some time to figure it out.

By knowing your water needs, you'll be able to know what size of a distiller that you'll need to get. A smaller family can make do with a countertop unit while a larger family will need a larger unit.

The right-sized distiller prevents you from constantly having to fill up a water distiller that's too small or spending plenty of money on an over-sized distiller that you don't actually need.

#2. Distilling Capacity

Asides from its water-holding capacity, the distilling or flow rate, is another important factor to consider. Most countertop units you'll find, for instance, need about 3 to 5 hours to produce a gallon of distilled water.

If you think this will be enough for you or your family, then it's okay, else, you'll have to consider models with higher flow rates, to meet up with demand.

#3. Material

The distillation process involves high temperatures and this means that using the wrong materials is potentially dangerous, as they can leach toxins into your drinking water.

To guarantee a safe and high-quality distilled water, you should focus on distillers that only offer stainless steel or glass components. These are the two major trusted materials, but there are also BPA-free plastics, which are safe so long as you don't heat them up.

#4. Energy Consumption

Energy consumption is also a necessary consideration when checking out water distillers because nearly all the models that you'll find in the market use electricity to heat the water.

Some models work with less power than others, so if you're concerned about energy use and saving costs, you may want to go for a lower-wattage distiller.

A typical home water distiller will use about 3 kWh (kilowatt-hours) of electricity to make a gallon of water. Simply multiply your electricity cost per kWh by 3 and you'll get your cost of producing one gallon of distilled water at home.

#5. Price

Keep in mind that larger distillation systems are costlier than small ones. Also, those that come with more fancy features will also cost more. It's left for you then, to strike the balance between cost and features because you alone know your budget.

#6. Carbon Filtration

Although distillation filters over 99% of the impurities in water, you should know that it does not filter any gases trapped in the water or VOCs (Volatile Organic Compounds) such as pesticide compounds.

The reason is that they have a boiling point which is lower than that of water, so they evaporate with the steam from the water and get cooled as part of the distilled water.

For this reason, some water distiller manufacturers offer a carbon filtration system as the last stage that the water must pass through after distillation.

This ensures that most of the VOCs are completely filtered out from your drinking water. Whether you want such an extra carbon filter or not, is up to you to decide.

Common Myths about Drinking Distilled Water

A lot of myths and misinformation are unfortunately circulated about the drinking of distilled water. Following is a list of the most popular ones, plus the real truths behind the myths.

Myth #1. Drinking Distilled Water weakens your Teeth

The Truth: Drinking distilled water will never weaken your teeth. Fluoride helps to strengthen teeth and the distillation process does remove it from the water, but there's always enough fluoride in toothpaste to make up for it.

Myth #2. Drinking Distilled Water reduces your Mineral Intake

The Truth: Although the distillation process removes all traces of minerals from drinking water, the level of minerals in water is too low to start with. Human beings get most of their mineral needs from food and not from mineral water.

You would need to drink 9 liters of water per day to get your body's calcium needs or nearly 1,000 liters per day for sodium. As you can see, most popular mineral waters don't really satisfy your daily minerals' needs.

Myth #3. Cooking with Distilled Water reduces your Meal's Minerals

The Truth: All types of cooking lowers the nutrient content of foods, especially when cooking in water. If you have any worries about maintaining your food's nutrients, then try steaming it, else, it doesn't really matter what type of water you use.

Myth #4. Making Distilled Water is an Expensive Process

The Truth: Most home water distillers use about 3 kWh of electricity to produce a gallon of water. Multiply your kWh cost of electricity by 3 and you'll see how cheap it is.

Myth #5. Drinking Distilled Water depletes the Minerals in your Body

The Truth: US Navy sailors have been drinking distilled water for decades and they are perfect proofs that distilled water does not leach minerals from your body.

Myth #6. Distilled Water has a Flat/Funny Taste

The Truth: It's actually the other way around, pure water is H2O and has absolutely no minerals in it. Distilled water is the closest to that and tastes just like pure water should, which is flat or tasteless.


We've reached the end of this water distillers review and you've seen the most interesting offers out there, as well as a guide to help you make the right choice.
