8 Best Water Distillers of 2021 – Reviews & Buying Guide

There is no way to purify water at home that is as effective as a water distiller.

If you want distilled water on tap, then an at-home distiller is, in fact, your only option! Luckily for you, they’re affordable, easy to use, and intuitive to understand the mechanics of.

The distillation process removes over 99.9% of contaminants including heavy metals, VOCs, chlorine, and pretty much anything else nasty you can think of.

Distilled water is the best option for lots of cleaning tasks, and distillation is the most effective way to treat your water in emergency situations.

Basically what I’m saying is, everyone should own some kind of at home water distiller!

Why you should use a water distiller

There are a whole bunch of reasons you might want to use a water distiller. They can be useful day to day, and in emergency situations depending on your water needs. They’re generally very easy to use (and intuitive to understand) which makes them a simple solution to several different water problems.

1. Because of water orders or contaminated water sources

If you’re under orders to boil water (because of an emergency situation or water supply issue), you can automate the process with a water distiller. Likewise, if you are afraid (or know) that a water source like a well or private water supply is contaminated you can use a water distiller to remove over 99.9% of contaminants.

2. To get rid of excess minerals

Although minerals like sodium, magnesium and calcium are necessary for the healthy functioning of our bodies, we can also get too much of them. If your water is just too mineral rich, either for you or for your appliances, then you can use a water distiller to get rid of those minerals. Do remember, though, that distilling water completely removes minerals. You need some in your diet, so be sure to add them in elsewhere!

3. To provide water for cleaning

Distilled water is great for cleaning. It activates soaps and other cleaning supplies better than most kinds of water, and leaves behind no mineral deposits. Distilled water is particularly recommended for cleaning hardwood and flagstone flooring.

4. To fill and maintain CPAP machines, engines, irons

Distilled water is the best water to use in a lot of mechanical equipment, including radiators, engines, CPAP machines and irons. When you have a distiller at home, you’ve got an ongoing supply of distilled water for all your mechanical needs.

So, what are your options?

Scroll down to find much more detail on each of these products, with my final thoughts and top picks at the end of the article.

1. H2o Labs Best-In-Class Stainless Steel Water Distiller - Best of the Best

If you want a top of the range water distiller, this is the only option.

H2o Labs Best-In-Class Stainless Steel Water Distiller

Pros

  • The highest quality distiller you will find for home use
  • Long-lasting activated carbon filter pods complete the water purification process
  • Slow-boiling and quiet
  • Triple-protected glass carafe

Cons

  • This is the most expensive distiller on the list - but it is worth it!

It’s all the same in some ways - activated carbon, stainless steel. Except it’s way more. The nozzle that feeds to the carafe in the Best-in-Class is porcelain, VOC removal is better than any competitor, and that stainless steel? Well, it’s the best grade you’ll find in most food environments, and so is every plastic component. There’s no BPA, and no cheap or sub-food-standard plastic anywhere on this distiller.

This is a water distiller that does the same stuff as most water distillers… only better. 

An optimally sized water heating element has been carefully chosen to make sure that water isn’t boiled too quickly, which means the steam won’t mix with VOCs or other contaminants. This is much more effective than the ‘splash shields’ that many competitors use. 

The glass carafe is also exclusively well built, triple-protected and comes with a supply of carbon pods that are up to 3x more long lasting than basic carbon filters. Additionally, your first jar of non-toxic cleaning crystals, designed to fight limescale buildup, are included with every purchase. 

Bottom Line

If you want a really high quality at home filter, then look no further than the Best-in-Class.


2. Waterwise 4000 

The Waterwise 4000 is, without doubt, a really great water distiller. It looks good, works well, and is at the top of the price range for products like this. But it’s worth it.

Waterwise 4000 water distiller

Pros

  • This is a great looking product
  • One gallon shut off function
  • Six gallons can be distilled in 24 hours
  • Larger capacity than most home distillation options
  • Easy to install and ready to use almost immediately

Cons

  • Can be a bit noisy
  • This distiller is one of the most expensive on this list

The glass water jug makes your whole setup look really high quality, and it’s practical too. The system uses stainless steel rather than aluminum, and although it can distill 6 gallons in 24 hours it has a built in 1 gallon shut off function. This is a really well-built machine that should stand  years of regular use. It’s made with high quality materials, and comes with a one year warranty for your peace of mind. 

There’s a post-distillation filter to make sure your water smells and tastes as good as it possibly can, but rest assured, 99.9+% of contaminants are removed from the water during the distillation process. 

The Waterwise 4000 requires no installation or hookups, you just have to plug in, fill and go. It’s perfect for a home anywhere, and is usable pretty much as soon as you get it into your kitchen. Like all distillers, it removes almost all contaminants from water including heavy metals, VOCs and dissolved solids.

Bottom Line

This is a premium product, just a small cut above the rest. If quality is your main concern, then go for the Waterwise 4000.


3. MH943SWS Megahome

This mid-priced distiller can handle up to a gallon of water per five hours. It’s attractively designed and suitable for almost any home.

MH943SWS Megahome

Pros

  • Amazing per gallon prices
  • Very dependable unit
  • Comes with charcoal filters
  • Made from 304 level stainless steel
  • Underwriters Laboratory listed

Cons

  • Can be a bit noisy
  • Not the most attractive kitchen appliance in the world

With the ability to distill one gallon per 5.5 hours, the Megahome gives most distillers a run for their money. A gallon, by the way, is almost 4 liters of water, so more than enough for a single person’s daily drinking water needs.

The setup includes six optional-use charcoal filters, so your water is as pure as it can possibly be by the time you’re drinking it, and all components that touch water are made from 304 level stainless steel.

All water poured into the unit is distilled and then filtered, and then stored in the outside tank that you can use as a super clean water source. Overall, costs are around 0.25-0.30 cents per gallon, according to the manufacturers and using a distiller like the Megahome also helps reduce the use of single use plastic bottles. 

Bottom Line

The Megahome is a really durable, high quality option for a mid-priced water distiller. If you want something solid and dependable that won’t break the bank, go for the Megahome MH923SWS.


4. CO-Z 110V - Best Countertop Distiller

If I had to say only one thing about this distiller? Well, I’d tell you it’s classy as hell!

Pros

  • A balance of quality and value
  • Great looking
  • Includes overheat protection
  • Includes a filter

Cons

  • A little noisy
  • Slower than some competitors, though not by much

Seriously! This space age looking water distiller can remove dissolved solids, VOCs, heavy metals and almost everything else for up to six gallons of water per day. 

The included BPA free plastic container is a half gallon, so if you want to run your CO-Z all day you’ll have to change it out or sort out a setup with a larger container and an intricate feeding method. That’s by no means difficult to do, but it may take a little MacGyvering.

If you want it broken down, this is essentially a kettle that feeds into a jug that holds the clean, boiled water. But, better than most kettles, the CO-Z includes overheat protection which means it won’t burn your kitchen down if you forget about it. It also has a non-slip base, ports for multiple plug sizes, and includes a filter.

This distiller works with single-button operation for both distilling water and cleaning the unit (you just need to add white vinegar to your water to run a cleaning cycle). The single-touch feature makes it an absolute breeze to use, no matter how busy you might be.

Bottom Line

This is, all in all, a really great looking water distiller. With its medium price point, it is probably one of the best options for most people who are interested in a balance of quality and value.

This fantastic budget still and distiller is perfect for a beginner, or use when traveling.

Seeutek Moonshine Still 3 Gal 12L Water Alcohol Distiller

Pros

  • Excellent value
  • Suitable for distilling and as an alcohol still
  • Comes with a 100% money back guarantee
  • Made from food grade red copper and stainless steel - no aluminum
  • Works as a portable still
  • No outlet needed

Cons

Made from non-toxic red copper and stainless steel, the Seeutek is safe for use with water or alcohol you will consume. It removes 99% of contaminants from tap water, and it comes with inbuilt thermometers to make sure all processes are taking place at the correct temp (temperatures are shown in fahrenheit and celsius for ease of use).

6. ROVSUN Stainless Steel Countertop Water Distiller

This mid-priced stainless steel countertop distiller from ROVSUN offers many features of more expensive plug-in distillers at a really manageable price-point.

ROVSUN Stainless Steel Countertop Water Distiller

Pros

  • This mid-priced unit balances value and functionality
  • Comes with a 12-month warranty
  • Includes activated charcoal sachets and cleaning solution
  • Easy to use, just plug in and fill up
  • Auto off function

Cons

  • Not the quickest distiller out there

Its stylish stainless steel body and glass collection jug are not only food-safe and high quality, and designed so that water never touches plastic, they also look modern and attractive and should fit in well with most modern kitchens.

The distiller purifies one liter of water per hour, and features an auto-shutoff when the chamber is empty. This both saves money and prolongs the life of your countertop distiller so you can ditch bottled water and purify your H2O yourself for years to come.

Speaking of which, the ROVSUN comes with a 12-month warranty, so that if you are unsatisfied for any reason you can return your distiller for a refund. Every unit comes packaged with five free gifts, too, including three activated charcoal sachets to remove and remaining contaminants from your distilled water, a soft catheter to reduce leakage, and chamber cleaning powder so you can keep your countertop distiller running beautifully by cleaning it between uses.

Bottom Line

If you’re looking for an easy to use, dependable electric countertop distiller for use on water and only water, look no further than the ROVSUN countertop.


7. Pure Water Mini-Classic CT

The Pure Water Mini-Classic Countertop is a solid, industrial looking water distiller at a really reasonable price.

Pure Water Mini-Classic CT 120v

Pros

  • An affordable water distiller
  • Quite a quick distillation process
  • Excellent warranties
  • Made in the USA

Cons

  • Can be noisy
  • The rugged looks aren’t everyone’s cup of tea

It can produce 3 liters of 99.9% pure water within 3.5 hours, so it keeps up with the fastest of the distillers on this list. It’s made in the USA from food-grade stainless steel, and the collection jug is fridge-friendly, thick-walled glass that will keep your water cool and fresh for days.

The whole unit is double-clad for safety (this prevents burns, and protects the mechanics of the distiller), and the stainless steel fittings come with an amazing 15 year warranty. Electrics come with a generous two year warranty, which is excellent compared to the 12-month warranty standard with this kind of equipment.

This is the perfect distiller for a single person or small family. It’s compact, neat, and can be left to run in the kitchen while you are off doing other things. It’s also super easy to clean without the use of any harsh chemicals - all you need is water, white vinegar and 8 hours to run a cleaning cycle!

Bottom Line

If you want simplicity and rugged, vintage style design in your water distiller, you’ll love having the Pure Water Mini-Classic sat on your countertop.


8. Mophorn Water Distiller Countertop

This mid-sized, mid-priced distiller from Mophorn is far from a middle of the pack piece of kit. Distilling a liter per hour, it keeps up with the quickest distillers on this list and it looks good while doing it, with a polished finish and a classic glass carafe for collection.

Things to Consider When Choosing a Water Distiller

Here are some things to consider when choosing a water distiller. Think about each of these elements before you choose a water distiller and you’re bound to find one that suits your needs to a tee.

1. Materials

Distillers tend to be made out of stainless steel, copper or aluminium. Sometimes there are plastic elements to countertop models. You should think about which of these metals you feel comfortable with, and if you have the budget to stretch to a glass collection jug that’s usually a good idea too for smell and taste reasons.

2. Capacity

How many people will you usually be distilling water for? If it’s just you, or you and your partner, then a distiller that is either a little slower or has a smaller capacity may suit your needs well and be a real bargain. If you have a larger family, you’ll want a quick, efficient water distiller with a multi-gallon capacity. Some countertop distillers can handle up to 5 gallons of distillation per day. 

3. Additional Filters

Do you need your distiller to include charcoal filters? That depends on your water supply, the smell and taste of your water, and personal preferences. Distillation removes 99.9% of contaminants from water at a minimum, so further filtration is very much a cautionary measure. 

4. Where You’ll Be Using It 

Will you be using the distiller only at home? Or do you want to take it to the office? This will affect the size and model of countertop distiller you choose. If you want a water distiller just for camping or emergencies, then a non-electric model might work best for you. Non-electric distillers are extremely long lasting, and can be stored for a long time without being tested or in any way maintained. 

5. Your Budget

Be realistic with how much you can afford to spend on a distiller. Think about what you spend on bottled water now, and how much you will save over a few months or a year. Is a top of the range model worth it? How often will you use your distiller? Prices really vary, so take the budget considerations seriously as you make your water distiller decision.

Types of Water Distiller

There are two main types of at-home water distiller you’re likely to find available for purchase. They are countertop distillers and non-electric distillers.

1. Countertop Distillers

Countertop distillers are a lot like electric kettles with additional chambers. They are self contained and need to be plugged in and filled up with water. Heating elements in the lower chamber heat the water to boiling point, at which point it becomes steam, moves to the upper chamber and then out of the spout and into a collection jug which is either BPA free plastic or, in higher quality countertop distillers, glass and stainless steel. The distiller chambers themselves are usually stainless steel, but some are aluminium.

Often, countertop distillers include additional charcoal or ceramic filters to ensure water purity. They tend to be easy to clean and maintain, and many of them have automatic shut off features and other safety controls that make them perfect for use within the home. Although they come in different sizes, countertop distillers tend to be at least semi portable. 

Occasionally, countertop distillers are also used to make wine although this isn’t always a feature. 

2. Non-Electric Distillers

Non-electric distillers are multi-chamber pots that work on a heat source like a stove. The smaller non-electric distillers on the market are excellent for travel, and work on camp stoves as well as they do on your home stovetop.

They’re great for use in emergency situations as well as outdoors and camping. The issue with non-electric distillers, though, is that you can’t leave them unattended. They’re a really good back up option, or a budget option if money is a concern.

Non-electric distillers usually include a large coil of copper or stainless steel, and adjustable vents. They can often be used as stills for alcohol as well as distillers, but again, the process needs to be carefully controlled and monitored. 

Distillers with Alcohol Distilling Functions

Some countertop distillers double up as wine makers, which is a similar process that takes place at a lower temperature. Some distillers, specifically usually stovetop or non-electric distillers, can be used as stills for distilling moonshine, rum, gin and other spirits.

Final Thoughts

There are several distillers on this list that I would happily use day-to-day. The selection available in 2021 is genuinely really impressive.

Overall, the best of the best has to be the H2O Labs Best in Class, with its porcelain nozzle insert and quiet, speedy distillation process. I am aware, however, that the H2O labs won’t be in everyone’s price range. 

More affordable, the ROVSUN is a very similar product. It’s a little slower and a little louder, but really ticks all the boxes, including that important auto-shutoff feature that’s so useful in a countertop water distiller. 

If you’re going camping or just need a distiller for emergencies, you can’t beat the Seeutek Moonshine. Its copper coil is impressive, and you can even get brewing moonshine when there’s no water boil order out!

You can’t go wrong with any of the distillers on this list, really, so weigh up your needs and pick the one that makes the most sense for you.
